“Perfection Without Compromise”

 Process West was established in 2003. The business has seen continual rapid growth and we now have approximately 95 distributor/resellers worldwide. In April 2012 we moved from our old 180m2 workshop to our brand new 900m2 factory. We specialise in the design, engineering and manufacture of small heat exchange products and other aluminium products for the automotive industry.

Managing director Kevin Westblade has been designing cooling, intake and fuel systems for 25 years.

With years of experience in the heat exchanger industry and traveling around the world to various heat exchanger manufacturing plants means that Process West uses only the absolute best available heat exchanger core and manufacturing processes.

We use the latest state of the art tig welding equipment and HAAS CNC vertical milling and lathe machines.
