CN-S Solar Series Pool Heat Exchangers

The market for Solar Thermal Heating has grown annually by 30+ percent in North America over the last 5 years as energy prices have continued to climb.

This growth rate is even higher among pool owners who have to deal with large heating bills and need to find ways to reduce costs.

The Solar Market has grown substantially to the point where a sizeable percentage of pool owners are now heating their pools indirectly with solar panels.

Solar heating of swimming pools is unique and differs in a number of ways from other heating methods. These systems run at their peak efficiency at temperatures lower than other indirect heat sources.

In order to maximize solar harvesting the CNS Series Cupro-Nickel Solar Range of Pool Heat Exchangers are constructed with longer tube bundles to increase the retention time.

These units are available in capacities ranging from 82,000 Btu/hr to 600,000 Btu/hr (at 158F).
