CN-P Series Pool Heat Exchangers

The use of external sources of heat as a means of heating swimming pools has increased significantly over the past decade. Indirect pool heating is becoming increasingly popular and is growing with alternative heating applications such as hydronic heating, solar thermal, geothermal and biomass heating. These alternative heating applications are energy efficient and will to grow in popularity due to rising energy prices.

In recent years there has been considerable growth in the popularity of saltwater pools. In certain parts of North America saltwater pools
account for over 80% of all new installations.

The Bowman CN-P Series Cupro-Nickel Pool Heat Exchangers are designed specifically for saltwater water pool applications. Cupro Nickel is
used widely in marine applications.

The CN Series is available in capacities ranging from 200,000 Btu/hr to 400,000 Btu/hr.
