Leverage Eaton Boyd Thermal chillers for a wide range of liquid cooling systems, including extreme temperature ranges or excessive heat loads. Our recirculating chillers are designed for flexibility by implementing a wide variety of performance-matched pumps, controllers and additional safety and monitoring features that enable you to tailor your chiller to your specific application.
Chillers are a mechanical device used to cool fluids in a liquid cooling loop by removing heat from the fluid. Recirculating chillers leverage compression refrigeration to reach sub-ambient temperatures and maintain high temperature stability.
Recirculating chillers have a wide range of applications from preventing key high-performance components from overheating or maintaining specific conditions for complex processes. Chillers can be found in data centers, manufacturing facilities, medical equipment, test and calibration equipment, air conditioning and refrigeration systems.
Chillers leverage vapor compression refrigeration to cool. They have a compressor, condenser, evaporator and an expansion valve. The compressor pumps refrigerant gas into the condenser. Refrigerant releases heat in the condenser and converts into a high-pressure liquid. This liquid flows through the expansion valve, undergoing a pressure drop and becomes a low-pressure liquid. As the liquid enters the evaporator, it absorbs heat from the fluid being cooled, which causes the refrigerant to evaporate into a low-pressure gas. The cycle repeats as the gas returns to the compressor.
Our custom recirculating chillers accommodate customer requirements including different process fluids, performance specifications, electronics and controls, dimensional and hardware specifications for integration, and regulation and certification compliance. By using field tested and enduring components, our recirculating chillers offer high reliability in even the most demanding applications; with standard chillers including a 2-year warranty.
Maintain extreme liquid coolant temperatures and cool high heat loads up to 50 kW with Eaton Boyd Thermal recirculating chillers designed to best fit your application requirements.
Recirculating chillers are designed for precise temperature control or cooling below ambient temperatures. Eaton Boyd Thermal chillers offer outstanding performance and high reliability with components performance-matched for quiet operation such as Positive Displacement Pumps (PDPs), Centrifugal Pumps (CPs) or Turbine Pumps (TPs). Custom PID controllers and advanced refrigeration control circuits ensure that the chiller maintains ±0.1° C (0.2° F) stability.
Eaton is responsive to customer support needs ranging from spare parts fulfillment to system service and repair solutions. Globally available service operations and factory-certified technicians provide rapid, effective and affordable service to minimize system maintenance downtime.
Low-temperature recirculating chillers are designed to maintain process fluid temperature stability over a wide range of target coolant temperatures from -80° C to 90° C or 4° C to 200° C. Our low-temperature chillers are designed with either a magnetically coupled gear pump or a turbine pump and are installed with internal heaters to maintain temperatures above ambient. By using field tested and enduring components, low temperature recirculating chillers offer high reliability in the most demanding applications.
High-capacity recirculating chillers are designed to cool high heat loads while still maintaining tightly controlled output temperatures. Our high- capacity chillers are designed with either centrifugal pumps for temperature control within 0.5° C or turbine pumps, which have a higher compressor capacity enabling the highest level of cooling of up to 50 kW.
