The SWEP 36N31 E5N brazed plate heat exchanger is a high-performance component designed specifically for use with combi boilers from Lennox. This heat exchanger is engineered to provide efficient and reliable heating and hot water solutions for residential applications.

Measuring 36 inches long, 31 inches wide, and 5 inches high, this heat exchanger boasts an impressive surface area of 661 square feet, ensuring optimal heat transfer. The brazed plate design is characterized by its thin, flat plates that are joined together at the edges using a brazing process, allowing for minimal fluid volume and quick response times.

Constructed from copper and brass, this heat exchanger offers superior durability and resistance to corrosion. The copper plates are coated with a thin layer of nickel for added protection against erosion and scaling. The brass end tanks provide additional strength and stability.

The SWEP 36N31 E5N is designed for use with a wide range of fluids, including water, antifreeze, and glycol. It features a double-pass flow configuration, which ensures efficient heat transfer by circulating the fluid through the plates twice before exiting the heat exchanger.

This heat exchanger comes with a number of advanced features to ensure optimal performance and ease of installation. It includes a built-in bypass valve, which allows for easy system balancing and improved flow rates. It is also equipped with a non-return valve to prevent backflow and protect against damage.

The SWEP 36N31 E5N brazed plate heat exchanger is a premium component that is perfect for combi boiler systems from Lennox. Its efficient design, superior materials, and advanced features make it an excellent choice for residential heating and hot water applications, offering reliable performance and long-lasting durability.
