Active Refrigeration Heat Exchangers
ETM has provided mechanical refrigeration cooling systems for applications where very high ambient temperatures exist or where close regulation of the coolant temperature is required. Where 24/7 operation is required, ETM has provided systems with redundant chillers so that one-half can be taken off-line for maintenance without interrupting service.


ETM Model 125REF
ETM Model 125REF Chiller System provides 125kW of cooling capacity with a flow of 75 gallons per minute. The refrigeration maintains the coolant temperature to 81 ± 4 degrees Fahrenheit.


ETM Model 25REF
ETM Model 25REF Chiller System provides 25kW of cooling capacity with a flow of 10 gallons per minute. The refrigeration maintains the coolant temperature to 84 degrees Fahrenheit. This system uses redundant refrigerated chiller elements to allow for maintenance or repair of one half of the system while maintaining operation.
