Swimming Pool Heaters - CN Series

swimming pool heaters

In response to the overwhelming popularity of salt water swimming pools, we are pleased to offer the CN series heat exchanger which are impervious to the corrosive effects of salt water. The CN series swimming pool heaters are designed with corrosion resistant cupro-nickel tubes and bronze end covers making a perfect fit for heating salt water pools, spas and hot tubs. Also visit our Pool Heat Exchangers website for more detailed information.

The CN series swimming pool heaters are ideal for applications ranging up to 1 million btu/hr. These salt water pool heaters are easy to maintain as both the end covers and tube stack can be removed for easy cleaning. At the moment, the CN series pool heaters are the only swimming pool heaters that offer this unique feature.

Because of the standard mounting brackets (vertical or horizontal) provided with each unit, the CN series pool heater is extremely easy to install. Standard uses for these pool heaters include the heating of pools using boilers or solar panels with either hot water or glycol as the heating medium. In warmer climates they are often used for cooling of pools using a chiller as the cooling source.
