A unique heat exchanger

Weplex®, the welded plates heat exchanger has been developed and patented in order to propose a unique thermic exchanger in the market due to its high thermic performances.

Weplex® is a large channels heat exchanger of new generation with improved solidity. Thanks to the use of laser technology to weld the plates, Weplex has a longer lifetime compared to other heat exchangers.
Weplex® heat exchanger is a high performance heat exchanger which is specially adapted to viscous and difficult fluids. Its compact design assures a quick installation and fast cleaning.

Weplex® is tailor made; its design, dimensioning and manufacture are assured in our industrial site of 10 000 m² in Tournan-France (40kms far from Paris). Our industrial experience of more than 70 years allows us to find solutions adapted to all applications.
