Packaged for easy installation, these chiller units are typically used in smaller buildings and offer lower installation costs.Find Out More
Natural Gas - Engine Driven Chillers
These are similar to their electric counterparts but use compressors driven by natural gas engines.Find Out More
Typically found in large chiller units, these are the most efficient systems and use one or more rotating impellers to compress refrigerant.Find Out More
Typically found in mid-size chiller units, these highly efficient systems use one or two rotating screws to compress refrigerant.Find Out More
Typically found in smaller chiller units, these use pistons and intake and exhaust valves to compress refrigerant. Only refrigerants that operate as a vapor can be used.Find Out More
This recent design uses one stationary and one orbiting scroll to compress refrigerant. Being more efficient, these will eventually replace most reciprocating compressors.Find Out More
A variety of electric motor, gas turbine, reciprocating engine, and steam turbine alternatives are available to drive chiller compressors.Find Out More
