NTRODUCTION

The Cornelius “CH” Series Recirculating Water Chiller is designed to provide an accurate, reliable and user--
friendly system for cooling a continuous flow of water and keep it at a constant temperature in various closed loop 
or tank cooling applications.

The “CH” Series Chiller consists of an air--cooled refrigeration system housed in a sturdy sheet metal frame and 
cabinet. A standard pump and insulated water reservoir package provides a complete liquid cooling and 
circulating system.

The “CH” Series Chiller is designed to operate in a clean laboratory or industrial environment where ambient 
temperatures range from 40 to100° F (5 to 38° C). With proper installation, operation and maintenance, the “CH” 
Series Chiller will provide years of trouble free service.
