With a focus on Brazed Plate Heat Exchanger technology, and the potential for commercial and institutional buildings, the below article is contributed by SWEP, a global supplier of brazed plate heat exchangers (BPHEs) for HVAC, district energy, and industrial applications. Founded in 1983 in Sweden and acquired by the Dover Corporation in 1994, SWEP’s North American sales network is headquartered in Duluth, GA, with the manufacturing center located in Tulsa, OK.
Brazed Plate Heat Exchangers, For Buildings, District Energy, And More
Brazed plate heat exchangers (BPHEs) provide efficient, stable, and reliable performance in a robust and easily handled unit for air conditioning, refrigeration, heating, industrial, and district heating and cooling applications. Customized to achieve the required characteristics of each specific application, they ensure the highest performance with the lowest life cycle costs. BPHEs have no gaskets to repair or replace, providing savings on maintenance and repairs compared with traditional gasket plate heat exchangers (PHEs).
The BPHE is, in principle, constructed as a package of corrugated channel plates between front and rear cover-plate packages. The cover-plate packages consist of sealing plates, blind rings, and cover plates. Connections are mounted on the cover plates and can be customized to meet specific market and application requirements. During the vacuum-brazing process, a brazed joint is formed at every contact point between the base and the filler material. Brazing the plates together rather than bolting them between gaskets is what makes BPHE technology so efficient and compact as 95% of the material of the brazed unit is used for heat transfer. The compactness of the BPHE also enables a modular design, just like modular chillers, improving redundancy and reducing fouling.
