Product Overview

The Raypak Professional ASME Digital heater is the perfect choice to help get more enjoyment out of your pool. These units meet the ASME pressure vessel requirements demanded by code for commercial installations over 200,000 BTUH and are certified to the ANSI Z21.56 pool heater standard. The Raypak gas heater has a polyester-coated, non-corrosive cabinet and the Wind-Resistant Design protects itself from the things that tend to stifle ordinary pool and spa heaters. The digital system requires external power and generates a pilot only when there is a call for heat. Its LCD digital display provides simple setup and easy programming, as well as easy-to-understand diagnostics and simple connections to remote controls. Every burner tray is built to last, from the stainless-steel burners to the aluminized metal used in the heat sensitive areas. Innovative design allows for the easy removal of the tray and burners for servicing. Has a unitherm governor that prevents condensation, wiring sheath and a robust burner. Flow switch and T and P are standard equipment on the Raypak Professional. This makes the unit 50 state ASME compliant right out of the box. Also, having a flow switch eliminates pressure issues from elevated pools.
