Selecting a Cooling System: Ambient Cooling System | Recirculating Chiller | Liquid-to-Liquid Cooling System | Recirculating Chiller or Liquid-to-Liquid Cooling System

A liquid-to-liquid cooling system cools below ambient temperature and offers similar temperature stability to a recirculating chiller. Instead of rejecting the waste heat to the room, it transfers it to chilled facility water via a liquid-to-liquid heat exchanger. The process side circuit is completely isolated from the facility water, protecting your equipment from fluctuations in temperature and flow rate of the facility water and any contaminants that may be present. Since the facility water provides the cooling, the facility water temperature is the lower limit for the fluid exit temperature.

Liquid-to-liquid cooling systems are popular for high heat load applications as they are compact - approximately 1/3 the size of a refrigerant-based chiller of similar capacity. Without a compressor, they are also very quiet and energy efficient.
