Are You Properly Cooling Your Engine While Testing?

Closed Loop Cooling Center

Your engine, while testing under load, requires a cooling system. Have you considered a glycol-based coolant instead of raw process water?  The advantage of a glycol-based cooling system is that you are operating the engine closer to its typical operating conditions.  In addition, the residual coolant in the engine will provide freeze protection and most likely corrosion protection without any additional processing.

Taylor has a family of Closed Loop Cooling Centers (CLCC), each sized to handle the heat rejection typically required for engines that are of 1,250 hp, 2,500 hp, 4,250 hp, and 8,000 hp (932 kW, 1,864 kW, 3,169 kW and 5,965 kW). 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.

The CLCC system utilizes a heat exchanger (liquid-to-liquid) and temperature sensor to control and monitor the coolant temperature. The coolant temperature is controlled by a set point that you set in the controller or remotely using a remote set point from the DynPro2 System.  All you need is an optional DynPro2 cable to enable this capability. The CLCC also includes a coolant pump within the enclosure. This coolant pump is used to fill and empty the engine before and after testing. A coolant tank of suitable capacity is required to complete the system and an expansion tank is required to capture gasses entrained in the coolant and allow for fluid expansion.

The design of your cooling storage and distribution system, needs to take into account your test cell layout, the amount of coolant required by the engine and capabilities of the engine and CLCC pumps. Contact Taylor to provide you with the proper coolant and storage distribution system specific to your test cell requirements email: or call (414) 755-0040.

Additional Cooling Components:

Large Cooling Column: For applications up to 4,250 hp (3,169 kW), large pressurized cooling columns regulate the jacket temperature and pressure of the engines being tested.

Small Cooling Column: For applications up to 1,250 hp (933 kW), an inexpensive, reliable, and easy to use engine jacket water cooler.

Low Temperature After-Cooler (LTA): Designed to regulate the secondary water circuit temperature on engines that use an onboard liquid-to-liquid heat exchanger (other than jacket water) to cool charge air.

Hose Interconnect Kit: Specially designed for quick connect and disconnect between the engines and cooling column and/or LTA.

Charger Air Coolers (CAC): A temperature controller with full PID auto-tuning. Typical applications include engines rated up to 3,000 hp (2,237 kW).
