BRAZED PLATE HEAT EXCHANGERS SERVICE, DELIVERY AND ADVICE

Q: How does a plate heat exchanger work?

Warm and cold fluids flow in opposite directions along the plates. Heat is transferred through the thin plate from the warm to the cold medium without the fluids mixing. The countercurrent principle ensures high thermal efficiency, even with relatively small temperature differences. The capacity can be easily increased or decreased by adjusting the number of plates.

Q: When is maintenance necessary?

Signals that maintenance or overhaul may be required: Reduced heat transfer Increased pressure drop Leaks between plates External leakage Fouling or scaling Unstable process performance Regular maintenance extends the service life and prevents unplanned downtime.

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:

We work independently of brands 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 tension bolts needed
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?

Warm and cold liquids flow in opposite directions along the plates.

The heat is transferred via the thin plate from the warm to the cold medium without the fluids mixing.

The counter-current principle ensures high thermal efficiency, even with relatively small temperature differences.

The capacity can be easily increased or decreased by adjusting the number of plates.

When is maintenance necessary?

Signs that maintenance or overhaul may be needed:

Regular maintenance extends the lifespan and prevents unscheduled downtime.

What is a plate heat exchanger?

A plate heat exchanger is a heat transfer device in which heat is exchanged between two fluids via thin metal plates.

The plates are equipped with elastomer gaskets that seal the flow channels and ensure that hot and cold media remain separated.

Due to the large heat transfer surface area and compact design, plate heat exchangers are particularly efficient and widely applicable in industry, HVAC, maritime, chemical, food, and energy sectors.
