FAQ - brazed plate heat exchangers

Our frequently asked questions

We have collected the most common questions and answers about brazed plate heat exchangers.


SWEP has pioneered the development of the gasket-free brazed plate heat exchanger which has several clear advantages over the gasket plate to frame heat exchanger. The brazed plate heat exchanger maximizes the most efficient transfer of energy, with 95% of its content. The life cycle cost over a period of 15-20 years can often be halved compared with gasket-plate solutions, which are built on a frame, require much more material and are thereby less efficient (the additional material does not provide additional heat exchange capability).

SWEP Software Package is our unique and world-leading software that has been developed for advanced heat exchange calculations. The software handles single-phase, condenser, evaporator, cascade calculations, two-stage applications and more. Input your data and SWEP Software Package immediately presents the product concept that best meets your needs.

A brazed plate heat exchanger is normally self-cleaning thanks to highly turbulent flows. In applications with a high risk of fouling or scaling due to unsuitable conditions such as questionable water quality and high temperatures (scaling), chemical cleaning may be necessary to maintain efficiency.

In such cases Cleaning in Place (CIP) is suitable, a convenient way of cleansing the interior surfaces of closed systems.

The mediums come into close proximity inside the brazed plate heat exchanger, on either side of the corrugated plate without mixing, and energy is transferred from one side to the other as they flow side by side.
