The varied operating conditions and specialist requirements encountered by military vehicle manufacturers require Grayson’s products to be enhanced to exceed specific contract specifications. This bespoke design requirement means that we must be able to produce designs constructed using heavyweight components that will remain durable at extreme temperatures, offering unrivalled thermal performance. It just so happens that we already have a range developed for this specific purpose.

Our EXT range is constructed from dimpled fin and heavy duty tubes. The tube to tube plate brazed joint used in the design is incredibly strong, and the construction minimises leak paths, thus ensuring reliability year after year.

All of our products are designed with a wide range of options our customers to up-spec standard vehicles without redesigning the base vehicle; this is useful where you have a specific operational requirement.

Products available include:

  • Complete cooling modules
  • Driver’s cabin heating/air conditioning
  • Radiators
  • Charge Air Coolers
  • Oil Coolers
  • Fuel/Hydraulic Tanks
  • Optional stone guards and filters
