The DXair-A Series base dehumidifier can be utilized as a packaged stand-alone indoor swimming pool dehumidifier, compressor, evaporator, 100% hot gas reheat condenser, Max-Evap option and air handler. The Max-Evap option is exclusive to DXair systems.
To maximize the latent capacity of any evaporator, there are 3 essential components to be addressed: coil temperature, coil surface area and dwell time. The challenge has been to reduce the coil temperature without compromising system air flow. DXair engineers have not only solved the problem but have implemented it in our entire product line under the trade name of MAX-Evap. Max-Evap is an exclusive design on all DXair dehumidification systems that allows the pool dehumidifier to maintain an evaporator coil temperature at 33 degrees F regardless of entering dry bulb or wet bulb temperature and it accomplishes this without compromising one CFM of system air flow. A matching remote DX condenser can be added if cooling is required. If pool heat recovery is desirable, all DXair-A systems are built with a Cupronickel double walled vented heat exchanger capable of rejecting 50% of system capacity to pool water.
The DXair A Series is a state of the art pool dehumidifier compared to all other conventional indoor swimming pool dehumidification systems such as Dectron, PoolPak, Seresco, Desert Aire, Dry-Aire, and more. Many current manufacturers continue to utilize un-cleanable 6 &8 row evaporator coils, which require larger horse power blowers to overcome the higher pressure drops substantially lowering system efficiencies and increase operating costs. The DXair A Series use high capacity, high efficient, cleanable 3/4 row coils and double-walled vented Cupronickel Water Coils for the pool heat recovery options. All units come standard with a K-type thermo-sensors pack, (8 point) & 1 external diagnostic LED array for system monitoring. These systems are CSA Certified and built in R410A.
We’ve been building our primary systems using the fluid cooler/dry cooler technology since 1988. Many companies claim 70-85% reduction in refrigerant using this “new” technology which has been around for over 30 years.
For example, a DXAIR nominal 8 ton pool dehumidifier has 9.25 lbs. total refrigerant installed (R410A). A competing manufacturer’s NE Series 8 ton has 34 lbs. of refrigerant. We provide the least amount of refrigerant per ton in any system design today.

The DXair B series is a liquid cooled packaged heat recovery pool dehumidifier that is factory charged and sealed; eliminating onsite refrigeration work. The refrigeration circuit uses glycol and water as a heat rejection transfer fluid to an outdoor fluid cooler or cooling tower. Several key advantages with the DXair B series: They are true Green Machines known as RRS (Reduced Refrigeration System) or Secondary Coolant Refrigeration Technology (SCRT) since it uses approximately 80% less refrigerant the conventional DX systems with outdoor remote condensers. (See bulletin #28) The use of RRS has substantiated many green benefits including lower installation costs, lower maintenance costs. Two pool heat recovery options are available on all sizes. A built in Cupronickel double walled vented heat exchanger rejecting 20% of unit capacity to the pool water in both dehumidification and cooling mode. A second option is an external 3 way diverter valve to a stainless steel plate heat exchanger connected to the pool water. This option allows 100% system heat rejection to the pool in the cooling mode and is secondary isolation.
Other advantages to fluid cooler/cooling tower technology: There is practically no limit to the distance the outdoor remote fluid cooler can be located from the building, it is non-invasive, there is no breaking into refrigeration lines to service, and is used in “Green” or Leeds Certified applications. Copper piping is not required, water grade plastic is appropriate. Our fluid cooler/dry cooler applications use the least amount of refrigerant in any packaged dehumidification system.
These fluid cooler RSS systems are built in R410A and have optional Bronze Glow Coating for coils, coated interior and exterior of cabinetry and in larger systems can be built in Stainless Steel. These systems are UL Listed and built in an ISO Rated Facility. Larger systems are built, tested and broken down to ship in modules for easy delivery and installation in mechanical space. Up to 10 Tons is built in single phase.
The DXair-G series is a one of a kind geothermal heat pump pool dehumidifier. No other company today builds a true geothermal pool dehumidifier designed for open or closed loop applications.
The geothermal pool dehumidification systems features the only NON-REVERSING Heat/Cool/Dehumidification system with 100% hot gas reheat and pool heat recovery in one very compact packaged unit. This very unique and innovative line has eliminated a major problem that has plagued the industry for decades. DXair-Geothermal Pool Heat Recovery series is a non- Energy Star rated unit applicable for open and closed loop applications for indoor swimming pools. The packaged heat reclaim dehumidification unit comes standard with compressor, evaporator, 100% hot gas reheat condenser, liquid to refrigerant shell and tube condenser/evaporator, Max-Evap option and air handler. This unit operates as a typical geothermal heat pump in heating and cooling. In the DH (dehumidification) mode, the shell and tube condenser/evaporator is not in play and the solenoid valve or loop pump is de-energized. The unit is now operates as a stand-alone pool dehumidifier with the Max-Evap energized maintaining a 33 Degrees F evaporator temperature while the unit rejects 100% of the sensible, latent and compressor heat to the space. Although not Energy Star rated, the COP’s and EER’s are very comparable. Electric built in duct heaters are available for second stage space heating. Hot water coils are often used as second stage heating as well.
The DXair-G-WR series utilizes an Energy Star rated geothermal heat pump and comes with an external patented design of our WR (water reheat) coil and proprietary control system. All modifications are external and do not to affect the Energy Star rating. The built in Cupronickel double walled vented D-Superheater can be used for pool heat recovery or domestic water heating.
