Grayson Thermal Systems supplies off the shelf and bespoke solutions.

Off-Highway vehicles are often subject to the most arduous of operating conditions. 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.

We supply off the shelf and bespoke solutions; all of our products are designed with a wide range of options enabling our customers to up-spec our systems.

These products are:

  • Complete cooling modules
  • Driver’s cabin heating/air conditioning
  • Radiators
  • Charge air coolers
  • Oil coolers
  • Fuel/hydraulic tanks
  • Optional stone guards and filters
