Reducing refrigerant in direct expansion (DX) HVAC system designs is a trend both contractors and consulting engineers are using to distance themselves from the competition. While refrigerant reduction has been fairly common in conventional air conditioning, it’s only now emerging in the category of indoor pool (natatorium) dehumidification.

Ranging from 18- to 140-ton units, the Protocol (NP) Series indoor swimming pool dehumidifiers provide energy-efficient natatorium space heating/cooling and optimum humidity control, while also offering free pool water heating and reheat through heat recovery.
