Duct dehumidifier.

When it comes to a vast pool, a duct dehumidifier always a first choice. If the swimming pool is under construction, then plan for a ducted dehumidifier. Based on the working principle, it is the same as that of a portable or wall mount unit. But, this dehumidifier for pool designed with high airflow. Besides, it creates higher external pressure. Hence, this inline system can integrate with the HVAC ducting. CtrlTech offers a wide range of duct mounted units for indoor pool rooms.

For the best performance, a unit should have air circulation without obstacles. This unit installed in technical rooms or any room near to the pool. Thus, the system is invisible, and it does not contribute any noise to the swimming pool room. CtrlTech offers DRY 400, DRY 500, DRY 800, and DRY 1200 duct mountable dehumidifier. The ducted system needs proper calculation and installation planning. Like any other dehumidification system, sizing is the same. But, we need to consider external pressure also as a primary parameter. 

DRY Duct dehumidifier.

DRY series duct dehumidification systems are most suitable for indoor pools. Yet, it capable of drying any space. This series consists of up to a capacity of 181 liters per day. It can address the swimming pool from small to extra large sizes. These systems can be mount on the floor or hung on the wall. Rectangle exhaust grill located at top and intake grill at the bottom. Cover made by galvanized steel with powder-coated enamel. Thus, this indoor pool dehumidifier protected from rust. As standard, casing painted in white RAL9010 color. But, users can order units in different colors also.

With a great look, more attention given to safety by providing grounding to the body. Hence, it protects users from electrical shocks. This system has a compact design so that it can install in a small pump room also. The depth of this duct dehumidifier is only 30 cm. DRY system equipped with a rotary compressor with R410a refrigerant. Compressor protected from vibration. The machine also has the facility to intake fresh air up to 30% of its standard capacity. Before releasing this fresh air to the pool room, it preheated by the condenser.

Features of dehumidifier for pool.

Like any other DRY series unit, this model also has a radial fan. By default feature, the unit has a digital and mechanical humidistat. The mechanical humidistat located at the left bottom or underneath the electro box. On the other hand, the digital system placed on the front panel. All the access panel opens from the front side. Thus, the machine is easy to do regular maintenance. Mechanical humidistat acts as a backup for digital. In case of failure in the digital module, the system works as per 70% level set on the mechanical humidistat.

Digital humidistat reads moisture levels of incoming air. And, depending upon the preset value, it either starts or stops dehumidification. It is vital to set a duct dehumidifier between 50 to 65% RH. Lower setting causes more consumption of power. This system has an option to use external humidistat to control it from the pool room. Also, it might disturb the physiological rules. If the installation is in a cold climate, then hot gas defrost helps to keep the unit efficient. It is an optional feature of the DRY series dehumidifier for pools.

DRY duct dehumidifier controls.

The role of the fan in a swimming pool dehumidifier is most important. The function of the fan handles the performance and energy efficiency of the unit. For DRY series duct models, the fan works in synchronism with the compressor. In other words, the fan operates when the machine is under drying mode. In the same vein, it gets idle when the compressor is off. And, as programmed, every 15 minutes, fan read humidity for 2 minutes.

During this, if the moisture level found to be less than the set value, then the fan remains off. But, if it is more than a preset value, then the fan starts at full speed. For installation, contact with the dealer since you need a trained technician. Leave clearances of at least 20 cm from both sides and 75 cm on the front side. This duct dehumidifier can have many optional features. For example, users can have a heater, LPHW coils, and wireless humidistat as options.

Advantages of a ducted dehumidifier for pool.

No doubt, the duct model brings lots of value addition than that of portable units.

• It installed away from the actual pool room. Hence, it does not contribute to noise. 
• These units are safe since the user does not come in actual contact with the user.
• It connected to AC or a separate duct system. Thus, a duct dehumidifier ensures uniform dehumidification.
• These units are easy to maintain without disturbing guests in pool rooms.

USPs 

• This unit delivers high airflow with high external pressure. Thus, it can be suitable to connect to AC ducts.
• Also, this dehumidifier for pools saves energy of proper programmed use of a radial fan. 
• This system has redundant humidistat. Besides, it can connect to a wired or wireless humidistat.
• The compressor is the best in quality with silent operation and free from vibration. Moreover, it is start-up delay protection.
• It has lower power consumption and a high energy recovery rate.
• This system has a facility connect boiler or electrical heater.
• With galvanized steel rust-free casing, the unit is durable.
