Information

The performance of chilled water heat exchanger mainly depends on the material, quantity and heat exchange area of ​​gasket, process, compactness of structure, etc. Let's talk about gaskets first. The materials of chilled water heat exchanger gaskets are carbon steel, stainless steel, aluminum and aluminum alloy, brass, Monel alloy, nickel, molybdenum, titanium, etc. The materials are different and the prices are different. Stainless steel is widely used. When some users need to deal with chlorine-containing or other corrosive media, they will use titanium material with good corrosion resistance, but the price is very expensive.

chilled water heat exchanger
In engineering applications, the heat load and working conditions are various. The version and geometric dimensions of chilled water heat exchangers are different, and the price difference is obvious. Among them, the pressure bearing quality of the gasket and the configuration of additional working conditions will increase the cost. The sealing gasket is mainly to prevent the leakage of the fluid and the leakage between the two fluids. It is subjected to pressure, temperature and erosion of the working fluid during operation. Therefore, it is required to have good elasticity. It is generally made of rubber, including nitrile rubber, ternary Ethylene-propylene rubber, fluororubber, neoprene, silicone rubber and asbestos fiberboard. Different working conditions, different material requirements, and different prices. Additional configuration includes configuring the structure of different functional segments such as heating, cooling, purification, and noise reduction according to user needs.
In addition, the thickness of chilled water heat exchanger gasket is usually in the range of 0.5~1.5mm. According to the needs of the working conditions, the thickness of the choice is different, and the price is also slightly deviated. Different corrugated forms of gaskets will have a greater impact on the heat transfer and flow resistance of the plate heat exchanger. Different corrugated gaskets are used according to different working conditions. Generally, herringbone corrugated plates and horizontal straight corrugated plates are the main ones. Prices will also vary. When production requires changing process conditions and output, increasing or decreasing the number of chilled water heat exchanger gaskets or changing the form of gasket assembly process channels, these operations will affect the price.
