Closed Loop Cooling

Power Test Closed Loop Cooling System (CLCS)

Test cell ready, engine coolant system that is used in place of an open-loop cooling column. Glycol systems provide corrosion and freeze protection in engines stored for extended periods or in cold environments. Stationary and Portable Closed Loop Cooling Systems are available in both Jacket Water (JW) and After Cooler (AC) models to suit your requirements.

Taylor Dyno Closed Loop Cooling Centers (CLCC)

We offer a family of Closed Loop Cooling Centers (CLCC), each sized to handle the heat rejection rates of 1,250, 2,500, 4,250 and 8,000 hp (932, 1,864, 3,169 and 5,965 kW) engines. The CLCC allows you to use a glycol-based coolant to regulate an engine coolant circuit temperature while cooling the CLCC with the facility process water.

Power Test – Portable Closed Loop Cooling System Features:

• Provides temperature control & pressure regulation of engine coolant/glycol.
• Separates engine coolant from facility water.
• Integrated transfer pump to fill & drain engine coolant.
• Stainless steel heat exchanger.
• Includes a coolant level sight glass that allows visual monitoring of the engine coolant for presence of oil or exhaust gases.
• Digitally controlled analog valve allows temp. set-point range of:
  JW Models: 160-205° F (71-96° C)
  AC Model: 125-150° F (51-65° C)

• 230° F (110° C) Maximum engine coolant inlet temperature.
