Available in either gasketed or brazed plate design. These units can be supplied to operate with pressures up to 30 bar. Manufactured from a variety of plate or gasket materials, units can be used with the most aggressive fluids and cooling media.

Built to meet designated application requirements, limitations to flow and dissipation do not exist. Plate heat exchangers are built on a module-based concept and are designed to provide maximum efficiency in transferring heat from one liquid to another, or from steam to liquid. Frames, plates and connections can be combined to form a number of different exchanger types. By using different types of plates, with different characteristics, the heat exchangers can be adapted to a wide variety of applications.

gasketed plate heat exchanger explanation
The benefit of the gasketed plate heat exchanger is that it can easily be expanded or adapted, by adding or replacing plates for different operational conditions.
Plate heat exchanger design pattern
GC and GL Plates
Symmetrical plates for regular use. Different plate patterns allow for optimisation of thermal transfer or pressure drop. An obtuse angle (high-theta plate) gives high resistance and an acute angle (low-theta plate) a low pressure drop.

GX Ultraflex Plates
The plates are available with a herringbone pattern and either an acute or obtuse angle, making it possible to achieve six channel combinations.

GD Double Wall Plates
Two plates laser-welded together for optimal safety. For applications such as the pharmaceutical industry, food industry, district heating, cooling of transformer oil etc., where it is vital that media are not mixed.

GF Wide Gap Plates
Plates with wide channels for fibre- and particle-rich fluids. The plate pattern is optimised for cooling applications to give high thermal efficiency even with asymmetrical flows.

GW Semi Welded Plates
With a sealed channel for ammonia and other fluids. The plate pattern is optimised for cooling applications to give high thermal efficiency even with asymmetrical flows.

Brazed Plate Heat Exchangers

SPB & SPBT series
The compact brazed plate heat exchanger (BPHE) is constructed as a plate package of corrugated channel plates with a filler material between each plate. During the vacuum-brazing process the filler material forms a brazed joint at every contact point between the plates, creating complex channels.

The BPHE allows media at different temperatures to come into close proximity separated by channel plates that enable heat from one media to be transferred to the other with very high efficiency. The concept is similar to the older plate and frame technology but without the gaskets and frame parts.

Simple, flexible, cost effective
The channel plates form separate circuits for each media. The number, type and configuration of the channel plates are easy to vary to provide the thermal characteristics required.

In a one-pass configuration, the two flows are continuous through each channel plate. In a two-pass configuration, the two flows are redirected by special channel plates to give the equivalent of two units connected in series.

In addition to one and two-pass configurations, we offer a variety of other executions and customised solutions.

The flows inside a heat exchanger can be arranged differently to fulfil different purposes. In these BPHEs, counter-current flow is more common because it increases efficiency. These BPHEs also employ co-current flow where necessary in applications such as flooded evaporators.

brazed plate heat exchanger flow
Compared with shell and tube type coolers of the same capacity these BPHEs are as much as 90% smaller by weight and volume.
The brazed plate heat exchanger is not only easier to transport and handle but its size means it also offers greater system design freedom. Further more connections are available in a wide range of industry standards.

Installation

The BPHE should be connected so that fluids flow counter currently to maximize performance. Piping should be installed so that no pulsations or pressure peaks from pump, valves, compressor, etc. are transferred to the BPHE. Filtration is recommended of mesh size 16-20 in front of BPHE.

A brazed plate heat exchanger for every need

The flexibility of these BPHEs makes them an excellent choice for many industrial applications. The wide range of plate sizes, plate pattern combinations and connections enables a virtually unlimited number of combinations.

You have the application, we have the solution!
