Raypak - ASME Cast Iron Digital Natural Gas 333,000 BTU Pool Heater

The Raypak ASME Digital Copper Heat Exchanger Natural Gas Heater with Cast Iron Headers is engineered to last. Raypak ASME rated heaters are intended for use when local codes mandate the use of ASME-certified equipment in commercial installations, such as apartments, condominiums and public pools and spas. The Raypak commercial digital heater is factory equipped with ASME waterways for commercial use and comes with microprocessor-based thermostat control. This allows the user to set the pool or spa temperature at a precise temperature using the up or down button. The digital display provides a constant reading of the pool's water temperature.
Looking at the heater, you can see that it's designed differently than most heaters on the market. The Raypak ASME Digital Natural Gas Heater's unique "pagoda design" enables the heater to stay effective during high wind speeds and downdrafts. The cabinet of the heater is constructed from a galvanized metal, then powder coated with a 7 stage process to outlast the elements and corrosion. Inside the unit, the heater boasts cast iron headers and a copper fin tube to stand up against harsh pool chemicals and dependable use.
