From technical selection to rapid delivery – we combine practical experience with an independent and solution-oriented approach.
Brazed plate heat exchanger
What is a brazed plate heat exchanger
A brazed plate heat exchanger (BPHE) is a compact heat exchanger where the plates are permanently joined together by copper or nickel brazing.
Due to the absence of gaskets, these heat exchangers are very compact, pressure-resistant, and suitable for applications with high temperatures and refrigerants.
Brazed plate heat exchangers are widely used in:
- Heat pumps
- HVAC systems
- Refrigeration and chillers
- Industrial process cooling
- Refrigeration systems
- District heating and central heating systems
We are brand-independent and tailor our approach to your installation and process conditions.

Advantages of a brazed plate heat exchanger
Brazed plate heat exchangers (BPHE) combine high heat transfer with a compact design. Because the plates are permanently joined together with copper or nickel brazing, no gaskets are required. This makes these heat exchangers particularly reliable and suitable for high-pressure and high-temperature applications.
- Compact design with minimal installation space
- Very high heat transfer and efficiency
- Suitable for high pressures and temperatures
- No gaskets or tightening bolts required
- Low maintenance and reliable
- Ideal for refrigerants and closed systems
- Long lifespan with proper use
- Available for HVAC, heat pumps, refrigeration, and process cooling
Brazed plate heat exchangers are widely used as evaporators, condensers, economizers, or liquid/liquid heat exchangers within heat pumps, chillers, refrigeration units, and industrial processes.
Are you looking for a replacement for an Alfa Laval, SWEP, Kelvion, Funke, Sondex, or Cetetherm brazed plate heat exchanger? Rell can assist with selecting a suitable alternative and can deliver worldwide for both new installations and replacement projects.
Applications of brazed plate heat exchangers
Brazed plate heat exchangers are used in a variety of installations where a compact design, high pressure resistance, and efficient heat transfer are important.
Thanks to the absence of gaskets, these heat exchangers are particularly suitable for closed systems and applications with coolants.
- Heat pumps
- Chillers and refrigeration units
- HVAC systems
- Process cooling
- Refrigeration systems
- District heating
- Tap water heating
- Industrial heat recovery
How does a plate heat exchanger work?
Hot and cold fluids flow in opposite directions along the plates.
Heat passes through the thin plate from the hot to the cold medium without the fluids mixing.
This counter-current principle gives high thermal efficiency, even with relatively small temperature differences.
By adding or removing plates, the capacity can easily be increased or reduced.
When is maintenance needed?
Signs that maintenance or an overhaul may be needed:
- Reduced heat transfer
- Increased pressure drop
- Leakage between plates
- External leakage
- Fouling or scaling
- Unstable process performance
Regular maintenance extends service life and prevents unplanned downtime.
What is a plate heat exchanger?
A plate heat exchanger is a heat transfer unit in which heat is exchanged between two fluids through thin metal plates.
The plates are fitted with elastomer gaskets that seal the flow channels and keep the hot and cold media separated.
Thanks to their large heat transfer surface and compact design, plate heat exchangers are highly efficient and widely used in industry, HVAC, marine, chemicals, food and energy.
