The cooling modules consists of electro pneumatic three-way valves, two units of heat exchangers for controlling engine coolant and oil rated 150kW which will marshal by independent temperature controllers to control the engine coolant and oil temperature during testing. Two thermocouples will be installed to monitor the oil and the water temperature from the engine. The accuracy of the temperature control setting will be within ± 2 Degree C.

Electro-pneumatic valves with air filter and regulator, air hoses, copper pipes and junction box. The input control signal is 4-20mA DC corresponds to 0% to 100% valve opening.
