Brazed plate heat exchangers are one of the most efficient means to transfer heat from one medium to another. Choosing brazed plate heat exchanger technology for your next heating or cooling project will provide many benefits, including minimal space requirements in the system, and savings in energy and maintenance cost.
A brazed plate heat exchanger consists of corrugated plates that combine to create channels through which a hot medium and a cold medium (typically water) can be distributed.
Brazed plate heat exchangers can be used for a range of functions in a heating or cooling system – they can act as condensers, evaporators, oil or gas coolers and be used for other functions that involve the transfer of heating or cooling.
Brazed plate heat exchangers are widely used in many different industries and often in large-scale residential heat networks. They play an important role in delivering air conditioning process and production, refrigeration, data center cooling and residential heating.
A brazed plate heat exchanger compared to a shell and tube heat exchanger and a gasket heat exchanger.
Compact – Our brazed plate heat exchangers are extremely compact compared with other technologies. The carbon footprint can be as little as one tenth that of a shell and tube heat exchanger or half that of a gasket plate heat exchanger.
Efficient – With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature differences efficiently.
Reliable – The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance and operational downtime.
Flexible – The compact size uses space efficiently and makes system design more flexible. Larger installations can be constructed unit by unit via standard doors and elevators, and it is easy to expand capacity when demand increases.
Cost-effective – You will save on energy, maintenance, spare parts, and installation. The life-cycle cost over 15-20 years can often be half that of a corresponding gasketed solution.
Self-cleaning – Our brazed plate heat exchangers are normally self-cleaning, thanks to highly turbulent flows. In applications with a high risk of fouling or scaling, Cleaning in Place is easy without disassembly. Read more about plate heat exchanger cleaning.
Customized – By combining plate design, materials, and connections from standard components, we keep lead times short while still maximizing output in your specific application.

We have collected the most common questions and answers about brazed plate heat exchangers.
The brazed plate heat exchanger maximizes the most efficient transfer of energy
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 for a brazed plate heat exchanger 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).
How to size a brazed plate heat exchanger?

How to clean a brazed plate heat exchanger?
Self-cleaning
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.

How do brazed plate heat exchangers work?
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.

Does your operation still rely on bulky, old-fashioned shell-and-tube heat exchangers for heating or cooling in your processes? Are you curious to learn about the benefits of switching to brazed designs? Brazed plate heat exchanger technology offers significantly higher thermal efficiency than comparable shell-and-tube models, within a much smaller footprint. Among other things, this can help you reduce energy consumption, increase your heat recovery potential, and resolve space and bottleneck issues in your plant. Ready to take the next step?
