The BPHE is in principle constructed as a package of corrugated channel plates between the 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. This design creates a heat exchanger that consists of two separate channels or circuits.
Sealing plates are used to seal off the space between the cover plate and the first and last channel plates. The number of cover plates varies, for example with the type and size of BPHE and its pressure rating. Some BPHEs have a blind ring to seal off the space between the channel plate and the cover plate. In others, the blind rings are integrated into the cover plate and first/last channel plates.

Compact – Our blazed plate heat exchangers are extremely compact compared with other technologies. The carbon footprint can be as little as one tenth that of a shell and tube heat exchanger or half that of a gasket plate heat exchanger.
Efficient – With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature differences efficiently.
Reliable – The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance and operational downtime.
Flexible – The compact size uses space efficiently and makes system design more flexible. Larger installations can be constructed unit by unit via standard doors and elevators, and it is easy to expand capacity when demand increases.
Cost-effective – You will save on energy, maintenance, spare parts, and installation. The life-cycle cost over 15-20 years can often be half that of a corresponding gasketed solution.
Self-cleaning – Our brazed plate heat exchangers are normally self-cleaning, thanks to highly turbulent flows. In applications with a high risk of fouling or scaling, Cleaning in Place is easy without disassembly. Read more about plate heat exchanger cleaning.
Customized – By combining plate design, materials, and connections from standard components, we keep lead times short while still maximizing output in your specific application

Certain BPHEs are available with different types of channel plates where the herringbone pattern varies. The benefit of different herringbone patterns is that the hydraulic and thermal characteristics of the BPHE can be modified. For example, two BPHEs can have the same pressure drop on both sides despite different flow rates.

The fluids can pass through the heat exchanger in different ways. For parallel flow BPHEs, there are two different flow configurations: co-current or counter-current (click images on the right).

Co-current flow
Counter-current flow

There are several different versions of the channel plate packages. Examples include:

Dual-circuit BPHE
Two-pass BPHE, which corresponds to two units connected in series.
Dual-over-two-pass BPHE
