3 Basic Types of Closed Loop Cooling Systems

There are various types of cooling systems for you to choose from according to the needs of your load. Each cooling system has its own unique features, pros and cons, so you should know your system well before investing. Among these cooling systems, one of the most effective types are closed loop cooling systems. 

Here are the 3 most important types of closed loop cooling systems:

• Closed Loop Dry Cooling System- The closed loop dry cooling system can be compared to the radiator in your car. This system uses air-cooled fluid cooler to transfer the heat from the fluid pumped through tubes that have air blown across them. Coolant temperature as low as 5 to 10 F above the ambient dry bulb temperature is possible with the help of a closed loop dry cooling system. These are very simple, easy to install and require fresh air to work efficiently. One of the best locations to set a dry cooling system is on the roof.

• Closed Loop Dry Cooling with Trim Cooling- A closed loop dry cooling with a trim cooling system is similar to a closed loop dry cooling system, but with additional supplemental fluid. This system is commonly used in a location that has too high of a dry bulb in summer and hence provides proper coolant temperature to the load. With an added liquid to the trim cooler, users can also use water sources to lower the temperature to the desired point. The closed loop trim cooler system can provide temperatures below than that of a closed loop dry cooling system. 

• Closed Loop Evaporating Cooling System- A closed loop evaporating cooling system is a hybrid system in an open tower with a built-in closed loop heat exchanger. The unique feature here is that the water stays outside the tower and does not circulate through the cooling pipes. The coolant piping is a closed loop with a glycol solution, flowing from the tower to the load and back. The main advantage of the evaporating cooling system is that it can deliver closed loop coolant to the load at approximately 7 to 10F above the wet bulb temperature.
