Silicon aluminum heat exchanger product introduction:
The special cast silicon aluminum heat exchanger for commercial condensing low nitrogen gas boiler is cast from silicon aluminum alloy, with high heat exchange efficiency, corrosion resistance, durability and high hardness. It is applicable to the main heat exchanger of commercial condensing gas boiler with rated heat load below 2100 kW.
The product adopts low-pressure casting process, and the molding rate of the product is higher than that of similar products at home and abroad. A removable cleaning opening is set on the side. In addition, the flue gas condensation heat exchange area adopts the company’s patented coating material, which can effectively prevent ash and carbon deposition.
Advantages of silicon aluminum heat exchanger products:
Space advantages： compact structure, small volume, light weight and small occupied space;
Material advantages: made of silicon aluminum alloy, high heat exchange efficiency and strong corrosion resistance;
Functional advantages: super acid corrosion resistance, super thermal conductivity; Reverse flow of flue gas and water to strengthen heat exchange.
Product features: the combustion chamber has a large furnace area, low temperature in the furnace and uniform distribution.
High efficiency and energy saving: efficiency up to 108% (water outlet temperature 30 ℃)
Safe and reliable: the rotary design is adopted for the water around the furnace, which avoids the dry burning phenomenon in the application process from the structure;
Service life: no weld, no stress, one-time molding by fine casting process, large heat exchange area and long service life;
