Raypak 017708 407A Digital Low NOx ASME Pool Heater

Raypak 407A Digital Low NOx ASME Pool & Spa Heater

The Raypak 407A Digital Low NOx ASME Gas Pool & Spa Heater is the highest-capacity model in Raypak’s Low NOx ASME series, engineered for the largest pools, spas, and commercial systems where dependable power is essential. With a heating input of 399 MBTU/h and 82% thermal efficiency, it delivers rapid temperature recovery for high-volume applications while balancing strong performance with energy-conscious operation. Certified to ASME standards, it is built to meet strict commercial codes for safety and durability.

Constructed for longevity, the 407A is protected by a corrosion-resistant galvanized steel cabinet and heavy-duty bronze ASME headers. Its straight-tube copper or cupronickel heat exchanger eliminates stress-prone bends, minimizing wear while delivering consistent results. Raypak’s exclusive ProTek Shield module adds another level of defense, absorbing corrosive elements commonly found in both chlorinated and saltwater pools. Together, these design features extend the heater’s service life and reduce long-term maintenance needs.

The 407A also incorporates intelligent digital controls with a microprocessor thermostat for precise temperature management and easy system integration. A self-adjusting burner maintains efficient combustion even during gas pressure fluctuations, while its Low NOx certification ensures compliance with stringent air-quality requirements in states such as California, Utah, and Texas. Designed for power, reliability, and convenience, the 407A is a proven solution for large-scale pool and spa heating.
