A STEP TOWARDS A MORE EFFICIENT REFRIGERANT INDUSTRY

Air dryers, chillers, cascade heat pumps and refrigeration systems are typical examples of applications that operate more efficiently using compact brazed heat exchangers (CBEs). The list of new applications is growing continuously, and today you will find SWEP CBEs in virtually all kinds/sorts of applications in the global refrigerant market. Alongside the increase in the areas of use, there is also a rapid technological changeover to modern high-effi-ciency SWEP CBEs where shell-and-tubes were previously used.

Extensive research and develop-ment combined with effective use of CFD (Computational Fluid Dyna-mics) have enabled us to offer the market's most comprehensive range of condensers, desuperheaters, evaporators and subcoolers for all types of refrigerant applications. And by using standardized compo-nents, we can cost-effectively mass customize the product precisely to your needs.

We can always offer you more, thanks to our complete program of effective aids. SSP, the SWEP Software package that we have developed for dimensioning ex-changers and dynamic drawing generation, is the soft way to get hard facts. Or why not do some in-depth reading in our Refrigerant Handbook, the complete handbook for CBE refrigerant applications? Contact one of our expert heat transfer consultants today to find out more about SWEP CBEs and energy-saving solutions.

Each SWEP CBE is delivered with full traceability and verified functionality. A SWEP CBE is approved by leading independent international bodies, such as PED, UL, KHK and CSA.

The conceptIn principle, a CBE is constructed as a plate 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. During the vacuum-brazing process, a brazed joint is formed at every contact point between the base and the filler material.

The fluids can pass through the heat exchanger in different ways. For pa-rallel flow CBEs, there are two dif-ferent flow configurations: co-cur-rent or counter-current.

There are several different versions of the channel plate packages. Be-low are some examples.
