017708 | Raypak 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 most powerful model in the Low NOx ASME series, built to handle the largest residential pools, spas, and demanding commercial installations. Delivering an input rate of 399 MBTU/h with 82% thermal efficiency, this heater provides fast and dependable heating for high-volume systems while keeping energy usage in check. Designed to meet strict ASME commercial code requirements, it combines rugged performance with advanced safety and compliance features.

Built to endure tough environments, the 407A features a corrosion-resistant galvanized steel cabinet, heavy-duty bronze headers, and a straight-tube heat exchanger available in copper or cupronickel. To further extend longevity, Raypak’s exclusive ProTek Shield module is included, protecting the exchanger from corrosive elements found in both chlorinated and saltwater pools. This added layer of defense makes the 407A one of the most durable pool heaters available for large-scale use.

For ease of operation, the heater comes equipped with intelligent digital controls and a microprocessor-based thermostat, allowing precise adjustments and compatibility with remote automation systems. A self-adjusting burner ensures clean, efficient combustion even when gas pressure fluctuates, while Low NOx certification guarantees compliance with strict air-quality regulations in states such as California, Texas, and Utah. With its combination of size, strength, and smart features, the Raypak 407A is engineered to deliver maximum performance with long-term reliability.
