Indoor swimming areas are usually maintained at about 10 to 15°C (18-27°F) higher than outdoor ambient for various reasons, the most important being to reduce condensation. That decreases ambient relative humidity (RH), which limits the size of your dehumidifier and saves on power consumption.
The indoor air is generally maintained at minimum 1.1-2.2°C (2-4°F) higher than the pool water temperature while RH is typically between 50-60% to provide optimum occupant comfort. Maintaining these conditions also helps protect costly infrastructure and equipment from corrosion.
Preheating incoming outdoor supply air prevents damage to the chilled water (CW) or direct expansion (DX) coils of the pool dehumidification unit (PDU). Post-humidification reheating also helps reach the desired indoor temperature set-point. We also offer corrosion-resistant designs with stainless steel (SS316 or 304) frames, elements and terminals.
Neptronic can build the required heaters according to your PDU’s specifications while using corrosion-resistant materials and innovative designs to fit your application.
