The cooling system, featuring Alfa Laval plate-type heat exchanger for cooling the drilling fluid for high pressure/high temperature wells, for increased safety. The unit is very compact and skid mounted, consists of either a single or dual plate heat exchanger depending on process requirements designed in accordance to ASME codes and standards.

The drilling fluid is pumped to the cooler via centrifugal pumps (optional delivery) from the clean fluid pit with the cooled fluid returning to the same pit. With this system, the oil based fluids can be maintained at surface below their flash points, improving safety and environment for rig personnel.
