We manufacture printed circuit heat exchanger (PCHE) flow plates for leading global suppliers of heat transfer solutions.

What is a printed circuit heat exchanger?

A printed circuit heat exchanger is a type of plate-fin heat exchanger that is based on the two technologies of chemical etching and diffusion bonding. Flow channels are etched chemically onto the metal plates then stacked to produce one block by diffusion bonding, a solid-state joining process.

Precision Micro and PCHE technology

Precision Micro has been at the forefront of PCHE manufacture since the 1990s.

Our market-leading chemical etching service offers volume versatility – from fast, cost-effective prototypes through to high volume manufacture.

We operate Europe’s largest PCHE production etching plant and can supply flow plates up to 1500mm x 600mm in size, and in thicknesses to 2.5mm.

Etched flow plate materials

Our chemical etching process is suitable for almost any metal type or grade.

Although our customers often specify printed circuit heat exchanger plates from stainless steel, we can also work with lightweight, corrosion-resistant metals such as aerospace grade aluminium or titanium for extreme environment applications.

Diffusion bonding service

We have long standing partnerships with world leaders in diffusion bonding technology and can offer a one-stop-shop for chemical etching and diffusion bonded flow plates.
