CtrlTech supplies whole house dehumidifiers and central ducted dehumidifiers for UAE villas, apartments & large homes. SPD ceiling-mount series. Dubai, Abu Dhabi, Saudi Arabia, GCC. Free survey.
Living in the UAE means accepting certain realities: temperatures that push past 45°C in summer, electricity bills that reflect it, and an ambient relative humidity that regularly exceeds 85–92% along the coast from June through September. Most homeowners address the heat with air conditioning and consider the matter settled. But the humidity does not leave simply because the temperature drops indoors. Walk-in wardrobes develop mould within weeks of a new season. Wooden furniture warps quietly over months. Paint peels along skirting boards. Children wake with blocked sinuses. The split AC units run harder, the electricity bill climbs, and the air still feels dense and damp.
The gap between what air conditioning delivers — temperature reduction — and what a UAE villa actually needs — temperature reduction plus active moisture control to a specific setpoint — is the problem a whole house dehumidifier is designed to close. Where a portable unit in a single room fights the symptom, a central dehumidifier for home treats the cause: it integrates directly with the villa’s existing HVAC ducting, processes every cubic meter of recirculated air, and maintains a target of 50–55% relative humidity [ASHRAE-recommended residential RH range] throughout the entire property, continuously, without any visible equipment in any room and without any condensate bucket that requires daily attention.
CtrlTech is the UAE and GCC’s leading specialist in residential whole house dehumidifier systems, with over 17 years of experience supplying, installing, and commissioning ducted ceiling dehumidifiers across Dubai, Abu Dhabi, Sharjah, Riyadh, Jeddah, Doha, Muscat, Sohar, Manama, Kuwait City, Amman, Baghdad, Erbil, Baku, Yerevan, and across Africa. Our SPD series ceiling-mount ducted dehumidifiers — from 50 L/day for apartments to 480 L/day for large villa compounds — are the standard specification for UAE MEP consultants, villa developers, and homeowners who want whole house humidity control done once and done properly.
Whether you are a homeowner frustrated with persistent mustiness in a Jumeirah villa, a property developer specifying a residential compound in Riyadh, or an MEP consultant designing the HVAC system for a new waterfront development in Doha — CtrlTech has the product, the engineering capability, and the regional installation infrastructure to deliver.
The UAE’s coastal geography creates a humidity environment that is structurally incompatible with standard villa HVAC design. The Arabian Gulf acts as a continuous source of moisture-laden air that pushes inland throughout the day, particularly during summer when sea surface temperatures are at their highest. In a villa, this ambient moisture enters through every gap in the building envelope — around window frames, through fresh air intakes, via bathroom and kitchen exhaust points, and across the positive pressure differential that opens every time an external door is used.
A split air conditioning system handles sensible heat — the heat you can measure with a thermometer. It removes some moisture as a by-product of cooling, but it was designed and sized to maintain a target temperature, not a target relative humidity. When a villa’s AC brings the indoor temperature to 22°C while outdoor air carries the moisture load of 88% RH, the indoor air stabilizes at a humidity level the AC cannot suppress — typically 65–80% RH. That is the range in which mold colonies textiles and wall surfaces, timber joints shift and warp, condensation forms on cold water pipes and glass surfaces overnight, and the human respiratory system works harder than it should even in a cooled environment.
The consequences accumulate over years in ways that are expensive and, in the case of mold on walls and soft furnishings, genuinely damaging to health [WHO dampness and mould in buildings report]. Warped doors and cabinetry that cannot be repaired without replacement. Mold behind wardrobes spreading undetected into the wall itself. Paint and plaster affected by cyclical condensation failing well ahead of any normal maintenance schedule. A whole house dehumidifier eliminates all of these downstream consequences by removing the moisture from the circulating air before it can settle on any surface.
A central dehumidifier for home in the UAE intercepts the return air stream of the villa’s existing HVAC system before it is cooled and redistributed. Humid return air from the villa’s rooms travels through the return air duct toward the air handling unit. At the connection point — installed in the ceiling void above the plant room or within the main duct run — the ducted dehumidifier draws in that return air, passes it across its refrigerant coil, extracts the moisture as condensate, and returns drier air back into the supply air stream distributed to every room through the existing grilles and diffusers.
Three connections are required at installation: a return air duct connection (in), a supply air duct connection (out), and a condensate drain to the nearest building drain point. A wall-mounted humidistat — placed in the master bedroom or the central living hall — controls the setpoint. When interior humidity rises above the setpoint (typically 50–55% RH), the unit starts. When the target is reached, it stops. The process is fully automatic, invisible in the living spaces, and silent enough to be unnoticed.
An inline duct dehumidifier retrofit installation in an existing UAE villa takes a single working day for a competent MEP contractor. In a new build, connection points are specified at design stage and integrated into the HVAC drawing set. CtrlTech provides AutoCAD drawings for MEP submission in both scenarios. For multi-storey villas with separate HVAC zones per floor, two units can be independently zoned with separate humidistats — useful where a ground floor kitchen generates a higher latent load than the sleeping floor above.
The SPD series ceiling-mount dehumidifier is CtrlTech’s primary recommendation for whole house humidity control in UAE villas and apartments. Installed within the ceiling void and connected to the existing HVAC duct system, the SPD series has no presence in any living space, drains condensate automatically, and operates silently at full extraction capacity regardless of outdoor humidity conditions. The SPD series covers villa sizes from small apartments at 50 L/day to large compound properties at 480 L/day. This is the best ducted whole house dehumidifier available in the UAE market for residential applications, combining refrigerant-cycle extraction efficiency at high ambient temperatures with seamless HVAC integration.
An inline duct dehumidifier sits directly within the main return air duct run, upstream of the air handling unit. For MEP consultants designing new villa HVAC systems, an inline dehumidifier HVAC specification is the cleanest integration approach — the dehumidifier is treated as a component of the HVAC plant, with duct connections designed from the outset. For retrofit installations in existing villas, an in-line duct dehumidifier can be installed in any accessible ceiling void with a connection to the main return duct, without any structural modification to the villa.
For property developers building villa clusters, residential towers, or large compound properties, a commercial ceiling mounted dehumidifier scaled to the full building’s air volume provides centralized humidity control from a single — or dual, for redundancy — installation. A commercial ceiling mount dehumidifier in the SPD-480L specification handles properties up to 380 m² from a single installation point, with larger properties served by multiple zoned units. CtrlTech provides compound-level supply and installation packages including design, documentation, and commissioning for residential developers across UAE and GCC.
Large UAE villas and mansions — typically above 800 m² gross floor area, spanning three or more independent HVAC zones across multiple floors, and specified with high-end interior finishes including solid timber flooring, custom joinery, bespoke marble surfaces, and curated art collections — require a central dehumidifier specification that goes beyond the single-unit approach appropriate for residential properties. At this scale, the whole house humidity control challenge involves managing different latent loads across distinct zones simultaneously. Treating all three zones from a single setpoint and a single unit means one zone is always either over-dried or under-controlled.
Dubai’s established villa communities generate the highest volume of whole house dehumidifier enquiries in the UAE. Jumeirah, Arabian Ranches, The Springs and Meadows, Palm Jumeirah, Emirates Hills, and Mirdif properties were delivered over the past 20 years with no whole house humidity control provision. Homeowners in these communities have accumulated years of mold remediation costs, warped cabinetry, and the running cost of portable dehumidifiers they manage themselves. A central dehumidifier for home in these properties ends all of it in a single one-day installation. In Abu Dhabi, Khalifa City, Mohammed Bin Zayed City, Al Reem Island, and Yas Island’s waterfront villa districts represent the same opportunity.
Property developers building villa clusters or gated compounds in the UAE, Saudi Arabia, or Qatar increasingly specify whole house dehumidifier systems as a standard amenity — particularly in the premium and ultra-premium residential segments where buyers expect the interior environment to feel as controlled as a five-star hotel. A built-in dehumidifier for villa UAE is a design decision made at MEP stage that costs a fraction of its value as a sales differentiator. CtrlTech works with developers from design stage through handover and post-handover maintenance across the UAE and GCC.
Large apartments in coastal residential towers — Dubai Marina, JBR, Downtown Dubai, Abu Dhabi’s Corniche, and Al Reem Island — face high infiltration loads from their proximity to the water and the constant fresh air requirements of occupied high-rise spaces. A ceiling mount dehumidifier for home integrated with the apartment’s ducted AC system provides the same whole house protection that villa installations deliver, within the ceiling void available in a typical Dubai Marina apartment layout.
Hotel rooms, serviced apartment units, and hospitality suite corridors face continuous latent heat loads from frequent occupant changeover, bathroom steam, and high fresh air ventilation rates. Commercial ceiling mounted dehumidifiers in the SPD series provide the continuous whole house humidity control that hospitality environments require, protecting soft furnishings, preventing mold behind furniture, and maintaining the 50–55% RH comfort band that guests associate with quality.
School classrooms, clinic examination rooms, and institutional spaces with high fresh air requirements and variable occupancy benefit from ducted inline HVAC dehumidification. Maintaining 50–60% RH in these spaces reduces airborne pathogen transmission conditions, protects building fabric, and meets the IAQ specifications increasingly required by UAE municipality and health authority building standards.
Community halls, theatres, cinemas, function rooms, and entertainment venues in the UAE face significant humidity control challenges due to rapid occupancy changes. Humidity can rise by 5–10% RH within 30 minutes of a full audience arriving. In Gulf summer conditions, repeated door openings and high latent moisture loads can overwhelm standard air-conditioning systems, making dedicated dehumidification essential for comfort, IAQ, and building protection.
Correct sizing of a central dehumidifier for home in the UAE requires three inputs: the villa’s total floor area (m²), the number of HVAC zones, and the worst-case ambient humidity the system must manage. The following table provides indicative capacity guidance at UAE summer peak conditions (30°C, 80% RH):

UAE Sizing Note: European catalogue capacity figures should be increased by 25–35% when specifying for UAE Gulf summer conditions. The SPD series is rated at 30°C / 80% RH — representative of UAE indoor conditions at peak season — and does not require this adjustment. Always confirm the rating conditions of any competitor unit before accepting its nominal capacity as applicable to a UAE installation. CtrlTech provides free villa sizing assessments — contact us with your villa floor plan or square footage for a same-day capacity recommendation.
A central dehumidifier installation UAE project requires access to the villa’s main HVAC return air duct — typically accessible from the ceiling void above the plant room or the main circulation corridor ceiling. Three connections are required: return air duct inlet, supply air duct outlet, and a condensate drain to the nearest building drain point. A 240V single-phase electrical supply and a humidistat signal wire from the unit to the selected control point complete the installation. CtrlTech provides AutoCAD duct connection drawings for MEP submission for new build projects. For retrofit projects, CtrlTech’s site survey team visits and assesses ceiling void access before any commitment. The most common retrofit in Dubai and Abu Dhabi villas is completable within six to eight hours from standard ceiling void access.
| Task | Recommended Frequency | Notes |
|---|---|---|
| Air filter inspection and cleaning | Every 4–6 weeks | UAE summer dust loads filters faster — inspect monthly Apr–Oct and clean before restriction reduces extraction capacity |
| Condensate drain confirmation | Monthly | Confirm auto-drain flow is unobstructed and condensate is clearing fully |
| Humidistat calibration check | Every 6 months | Verify against reference hygrometer; adjust setpoint if drift detected |
| Full CtrlTech service — compressor, fan motor, coil clean, refrigerant check | Annually | Schedule before summer peak (March–April) to ensure full capacity available from June |
| 🏜 Gulf Tip: UAE summer sand and dust loads air filters significantly faster than European climates — inspect monthly during April to October and clean or replace before any restriction reduces airflow, which directly reduces extraction capacity at the moment of highest demand.

Maintaining 50–55% RH prevents the surface moisture conditions that allow mold to establish and grow — ending the cycle of remediation, repainting, and textile replacement that high-humidity UAE villas generate every season.
Wood absorbs and releases moisture in response to the surrounding environment. Warped doors, swollen drawer runners, cracked veneer, and splitting timber are all symptoms of cyclical humidity variation. A central dehumidifier for home stabilizes indoor RH and therefore the moisture content of all timber in the villa, stopping seasonal movement before it causes visible damage.
Air at 50–55% RH feels fundamentally different from air at 70–80% RH at the same temperature. Occupants consistently describe the difference as lighter, cooler despite the same thermostat setting, and more comfortable for sleeping. Respiratory symptoms associated with mold spore exposure reduce measurably.
Humid air carries a latent heat load that the AC must remove before it can begin sensible cooling. By pre-removing that latent load, a whole house dehumidifier allows the AC to reach its temperature setpoint faster and cycle off sooner — typically delivering a measurable reduction in AC electricity consumption within the first full season of operation.
A UAE villa with documented whole house humidity control, no mold history, and intact joinery and finishes is worth more and more lettable than an identical property without it. For property investors, a central dehumidifier is an asset protection investment with a calculable return.
Unlike portable dehumidifiers that require daily emptying and regular repositioning, a ducted ceiling unit manages itself entirely — condensate drains automatically, the humidistat manages the cycle, and the occupant interacts with it no more than with any other fixed HVAC component.
CtrlTech is not a general HVAC contractor that installs dehumidifiers as a secondary product line. Every engineer, product, and service protocol in our business is built around a single discipline: dehumidification. That specialisation, sustained for over 17 years and 2,000+ installations across the UAE and GCC, produces consistently reliable results in a product category where incorrect sizing, wrong technology selection, or poor installation creates problems that take months to discover and are expensive to rectify.
Our residential installation team has completed whole house dehumidifier projects in the same villa communities, the same floor plan configurations, and the same HVAC duct layouts dozens of times. The site survey, the sizing calculation, the duct connection assessment, and the commissioning verification are not new work for us in any standard UAE villa format. For the homeowner, this means a faster survey-to-installation timeline, a more reliable sizing recommendation, and a post-commissioning RH measurement confirming the target has been achieved before we leave the property.
We carry SPD series stock in the UAE continuously. A site survey can typically be arranged within 48 hours of enquiry. Installation follows within the same week for standard villa formats. We service our own installations under an optional annual maintenance contract and provide post-installation technical support by phone and WhatsApp at no additional charge. Our regional engineering team serves the UAE (Dubai, Abu Dhabi, Sharjah, and all seven Emirates), Saudi Arabia (Riyadh, Jeddah, Dammam), Qatar (Doha), Oman (Muscat, Sohar), Kuwait, Bahrain (Manama), Iraq (Baghdad, Erbil), Jordan (Amman), Azerbaijan (Baku), Armenia (Yerevan), and Africa.
The villa is a four-bedroom, two-storey property in one of Dubai’s established villa communities — built in the mid-2010s, approximately 340 m² of conditioned floor area across two floors, with a single ducted central air conditioning system serving all rooms from two AHUs in the ceiling void above the ground and first floors respectively. The owners had lived in the property for four years before contacting CtrlTech. During that time, they had replaced two sets of bedroom wardrobes due to mold damage to the internal shelving and timber frames, repainted the master bedroom and one guest bedroom to address wall mold that had developed behind furniture during the previous two summers, and purchased two portable dehumidifiers — one for the master bedroom, one for the main living area — both of which they emptied daily during summer and described as ‘a constant maintenance task that solved the problem in one room and left every other room exactly as it was.’
A CtrlTech site survey recorded the villa’s indoor conditions at the start of June — before the peak Gulf summer humidity season. Interior relative humidity across the ground floor was averaging 74–78% RH at 22°C, with the master bedroom first floor measuring 71% RH. The external ambient condition that morning was 88% RH at 36°C. Both AHUs were operating at full cooling capacity.
CtrlTech installed a single SPD-136L ceiling-mount ducted dehumidifier into the existing return air duct plenum above the first-floor ceiling void. Total installation time: six hours from access panel to commissioning completion. The condensate drain was routed through the ceiling void to the nearest bathroom drain stack — no structural modification required anywhere in the villa. The humidistat was positioned in the master bedroom at 1.5 meters above floor level, away from any supply grille. Target setpoint was agreed at 53% RH for general comfort and mold prevention. The owners were not present during installation.
CtrlTech returned to the property 72 hours after commissioning to conduct the first post-installation measurement. The data below reflects conditions measured at the same time of day (10:00 AM), under comparable outdoor ambient conditions (86–89% RH, 37–38°C), using the same calibrated reference hygrometer used at the initial site survey.
4-bedroom villa, Dubai — approx. 340 m², single ducted AC system, SPD-136L installed in ceiling void. Measurements taken at 10:00 AM before and 72 hours after commissioning under comparable outdoor ambient conditions (86–89% RH, 37–38°C). Calibrated reference hygrometer used at both measurement dates.
| Measurement Point | Before Installation | 72 Hours After Commissioning |
|---|---|---|
| Ground floor — main living area | 76% RH | 52% RH ▼ 24 percentage points |
| Ground floor — kitchen | 78% RH | 54% RH ▼ 24 percentage points |
| First floor — master bedroom | 71% RH | 51% RH ▼ 20 percentage points |
| First floor — guest bedroom | 73% RH | 53% RH ▼ 20 percentage points |
| First floor — landing / corridor | 74% RH | 52% RH ▼ 22 percentage points |
| AC cycling frequency (ground AHU) | ~42 mins ON / 8 mins OFF | ~26 mins ON / 22 mins OFF ▼ approx. 38% less compressor runtime |
| Condensate extracted (per 24 hrs) | N/A (pre-installation) | Approx. 118–124 litres Moisture removed from villa air daily |
| All five room measurements moved from above 70% RH to below 55% RH within 72 hours of commissioning — within the 50–55% RH target range recommended for UAE villas to prevent mould, protect timber finishes, and reduce AC latent heat load. The AC runtime reduction (42 min → 26 min compressor-on cycles) is consistent with the latent heat load reduction that whole house dehumidification provides when correctly sized and installed.

The owners returned to the property on day four after installation. Their first observation — before we had explained any of the measurement data — was that the air in the villa felt different. Their exact words: ‘It doesn’t feel like you’ve walked into a damp room anymore.’ When shown the 72-hour RH data, their second observation was the AC cycling pattern: ‘The AC isn’t running all the time. I can actually hear it switching off now, which I don’t think I ever noticed before.
By the end of the first summer season, the owners reported no new mold growth anywhere in the villa — including in the wardrobes that had previously required replacement within two years of use. The two portable dehumidifiers were removed from service within the first week and have not been used since.
This installation is typical of what CtrlTech delivers in standard UAE four-bedroom villas in the 280–400 m² floor area range. The specific data will vary by property — ceiling height, number of occupants, window area and orientation, fresh air ventilation rate, and the condition of the existing HVAC system all affect the outcome. What does not vary is the fundamental result: when the moisture load is removed from the air before it circulates through the rooms, the AC performs the job it was designed for — cooling air that is already at an appropriate humidity level — and the villa reaches and maintains a comfort standard that air conditioning alone cannot achieve in the UAE Gulf summer environment.
Contact CtrlTech on +971 50 153 7113 or WhatsApp for a free villa humidity assessment. We measure your current interior RH, recommend the correct SPD series model for your floor plan, and confirm the achievable post-installation setpoint before you commit to anything.

While selecting a whole house dehumidification system, home owner should ensure that unit has following features at least to ensure better performance.
Eliminates all visible equipment from living spaces; condensate drains automatically to building drainage; no daily occupant maintenance.
Capacity should verified at 30°C and 80% RH — representative of UAE indoor peak conditions. Never use European-rated figures without verifying the test.
Ceiling void installation isolates mechanical noise from living spaces. SPD series units do not require acoustic attenuation in typical UAE villa ceiling depths.
Maintains target 50–55% RH automatically. Optional tighter setpoint (45–50% RH) for premium villa finish protection of timber, marble, and artwork.
Condensate drains continuously to building drainage system. No tank to empty. Essential for any unoccupied or infrequently visited property.
Units should support BMS dry contact outputs for humidity monitoring and remote status visibility in smart home and building management systems.
High-efficiency compressor and EC fan motor maintains extraction performance without adding disproportionately to UAE residential electricity bills.
Unit should provided with wall mount LCD controller to allow user to set required humidity, Fan speed, automatic on/off timer, and other parameters
Whole house dehumidifier should automatically restart one failed power gets resumed and start working with privious settings saved by the user.
A whole house dehumidifier — also called a central dehumidifier for home or a ducted dehumidifier — is a fixed unit installed within the villa’s HVAC ceiling void or duct system that processes all of the home’s recirculated air through a single installation. It connects to the return air duct (drawing moist air from every room) and the supply air duct (returning drier air to every room), with condensate draining automatically to the building drainage system. A portable dehumidifier processes the air in a single room, requires daily manual emptying of its condensate tank, generates heat and noise in the living space, and leaves the rest of the villa untreated. For any UAE villa above two bedrooms, a whole house ducted system is the correct specification — portable units are a temporary measure that most homeowners replace within one to two seasons.
Whole house dehumidifier prices in UAE depend on villa size and HVAC zone count. The SPD-50L (50 L/day, apartments up to 80 m²) starts from AED 13,500. The SPD-136L (136 L/day, villas up to 200 m²) starts from AED 16,800. The SPD-240L (240 L/day, villas up to 400 m²) starts from AED 28,000. The SPD-480L (480 L/day, villas up to 600 m²) starts from AED 36,500. Central dehumidifier installation UAE costs — including duct connection, drain routing, and humidistat wiring — are assessed at site survey and quoted separately. Contact CtrlTech with your villa square footage for a same-day budget range.
Yes. Retrofitting an inline duct dehumidifier into an existing UAE villa is a one-day installation requiring only ceiling void access to the existing HVAC return air duct. No structural modification, wall opening, or major civil work is required in most standard UAE villa formats. CtrlTech’s site survey team assesses the ceiling void access and duct layout and confirms the installation approach before any commitment. The most common retrofit in Dubai and Abu Dhabi villas involves a ceiling void access panel — standard in most UAE builds — and a direct duct connection to the return air plenum, typically completable within six to eight hours.
For general residential comfort and mold prevention, the target relative humidity for a UAE villa is 50–55% RH. Below 50% RH, the air begins to feel dry for some occupants. Above 60% RH, mold colonization risk increases measurably and timber begins to absorb moisture that will cause movement and warping over time. For premium villa finishes — marble flooring, solid timber furniture, artwork, and high-specification joinery — a tighter target of 45–55% RH ±3% provides better protection for sensitive materials.
In the majority of UAE villa installations, a whole house dehumidifier reduces the overall electricity bill by lowering the AC’s latent heat load. When the AC no longer needs to remove the full moisture content of incoming humid air before it can begin sensible cooling, it reaches setpoint faster, cycles off sooner, and runs fewer compressor hours per day. The electricity consumed by the dehumidifier is more than offset by the reduction in AC runtime, particularly during the June–September peak humidity season. Individual results vary by villa size, occupancy, and HVAC system condition — CtrlTech can provide a site-specific energy assessment on request.
Yes. CtrlTech supplies whole house dehumidifier Saudi Arabia projects from UAE stock with delivery in two to three working days. Active supply destinations include Riyadh villa compounds, Jeddah waterfront residences, Mecca and Medina hospitality properties, King Abdullah Economic City residential developments, and Dammam and Al Khobar’s Eastern Province villa communities. All Saudi Arabia supplies include post-installation commissioning support and site-specific sizing documentation.
A ceiling mount dehumidifier sits within the ceiling void and has its own air inlet and outlet — it draws room air directly through the ceiling, processes it, and returns drier air, without necessarily connecting to the villa’s main HVAC duct. An inline duct dehumidifier connects directly into the main HVAC return and supply ducts, integrating with the full air distribution system. For a whole house application in a UAE villa, the inline duct connection is always preferred because it ensures every room’s air is treated. CtrlTech specifies the appropriate integration method at site survey based on the villa’s ceiling void access and duct layout.
Yes. The SPD series whole house dehumidifier operates independently of the villa’s AC system. It has its own fan motor that draws air through the duct connection regardless of whether the AC is running. This means the dehumidifier can protect the villa during transitional seasons when AC is not required for cooling but humidity remains elevated — typically April–May and October–November in the UAE — and during extended vacancy periods when the property is closed. This capability is particularly valuable for holiday homes and investment properties unoccupied for several months at a time.
Yes. CtrlTech supplies whole house and ducted central dehumidifiers across the full GCC from UAE stock. Qatar (Doha, Pearl Qatar, West Bay): three to four working days. Oman (Muscat, Sohar): three to four working days. Kuwait, Bahrain (Manama): three to four working days. Jordan (Amman), Iraq (Baghdad, Erbil): four to five working days. We also supply to Baku (Azerbaijan), Yerevan (Armenia), and across East and West Africa. Contact CtrlTech with the project location and villa floor plan for a region-specific quotation.
The two primary inputs are the villa’s floor area in m² and the number of separate HVAC zones. As a practical guide for UAE peak summer conditions: apartments and small villas up to 80 m² need 50 L/day (SPD-50L); 3–5 bedroom villas of 80–200 m² need 136 L/day (SPD-136L); large villas of 200–400 m² need 240 L/day (SPD-240L); and very large villas or small compounds of 400–600 m² need 480 L/day (SPD-480L).
