Brazed plate heat exchangers

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.

tailored » optimised and customised.

performance » reliable, energy efficient and cost effective.

economical » optimal material usage.

versatile » cover a wide range of cooling and heating capacities.

turbulent » resist scaling and fouling; effective self cleaning.

innovative » true dual, double-wall and asymmetric brazed plate heat exchangers.

tested » pressure and leak tested. All widely recognized pressure vessel codes available eg. PED, KHK and UL.

responsive » small hold-up volume and lower refrigerant charge.

standards » comply with standards such as ISO 9001 (quality) and ISO 14001 (environmental).

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!
