Swimming Pool Heat Exchanger design conditions:

  • Shell Side Pressure: 90 PSI (6 Bar)
  • Shell Side Temperature: 248 F (120 C)
  • Tube Side Pressure: 90 PSI (6 Bar)
  • Tube Side Temperature: 212 F (120 C)

Pricing and technical data for models with capacities up to 7,000,000 btu/hr [2000 kW] are available upon request.

To maximize the performance of a swimming pool heat exchanger, it should be installed in a counter-current flow method. The hot, or heating, fluid flows through the shell side. The cold (pool water) must flow through the tube side in the opposite direction.
