The CN-XL series of heat exchangers was designed specifically for commercial sized swimming pools. They provide a simplified and practical means of indirectly heating both commercial and municipal pools. The vast majority of hotels, YMCAs, municipal arenas, community centers, universities/colleges and condominiums already utilize boilers for makeup air and domestic water heating. Typically these boilers are oversized and are not in operation on a continuous basis even during the winter months. Utilizing this excess capacity also ensures a more continuous operation of the boiler which reduces cycling.
The CN-XL series heat exchangers are available in capacities ranging to 3,000,000 Btu/hr and are therefore suitable for large Olympic size swimming pools.
In addition to providing sufficient surface area to facilitate high rates of heat transfer these units are also designed to handle a flow rate of 400 USGPM of pool water with a pressure loss of only 3.2 psi (7.5 feet water). As these are engineered products it is important that they are correctly sized for the application. Please contact us with the design parameters and we can size a suitable unit and provide a data sheet with the design criteria and flow characteristics.
