Tube and Shell Heat Exchanger 400kBtu 304 Stainless Steel for Spa Heat Recovery. 304 Stainless Steel Tube and Shell Heat Exchanger 400kBtu for Spa Heat Recovery. The pool heat exchanger is made of high-grade anti-corrosion stainless steel, which has the characteristics of anti-rust and salt water resistance, so it is very durable and very suitable for chlorine or salt pools and spas. 2 inch FPT is used for swimming pool water, and 1 inch FPT is used for hot water. The salt pond heat exchanger adopts an innovative in-line design to ensure a continuous constant temperature and indirectly transfer heat between any hot water circuit, steam circuit and any swimming pool or spa facility. The shell-and-tube heat exchanger is based on the 60°C (140°F) temperature difference between the inlet and hot water, and can provide a fresh pond of 400 kBtu/hr. It gets hot immediately without waiting. This kind of heat exchanger is a very safe, reliable, efficient and cost-effective way to heat swimming pools or spas through any hydraulic system. The heat recovery pool heater is very suitable for swimming pools, spas, hot tubs, solar, hydraulic heating, oil cooling, heat recovery, snow melting, etc. Material: 304 stainless steel. Output: 400 kBtu / hr. Heat transfer area: 11.8 square feet. Hot water flow rate: 50 L/min. Cold water flow: 360 L/min. Side of hot water pipe: 1 FPT. Port on the same side: 2 inch FPT. 1 x stainless steel heat exchanger. 2 x fixed bracket.
