Heat Exchangers

Many more sizes and styles of heat exchangers are available, including models suitable for pool heaters and salt water applications. Also available are heat exchanger mounting brackets and Aeroflex pressure sensitive insulation kits to seal against condensation on cold temperature fluid applications. Consult the factory for details.

Please Note The heat exchanger BTUH ratings shown are very conservative, and were derived using familiar system temperatures, flow rates, and pressure drops. For each heat exchanger, the BTUH output can be greatly increased by choosing different system design temperatures and increasing flow rates
