The best way to size your plastics chiller is by the information provided by the plastics machine manufacturer. For used equipment or when OEM cooling information isn’t available this chart can assist. Always round up or go up one size for adequate cooling capacity.

ABOUT GLYCOL IN CHILLERS

A chiller will run without glycol as long as the fluid temperature in the system is above freezing. Glycol or other inhibitors are recommended for most process cooling applications even if the fluid temperature doesn’t reach temperatures near freezing.

What type of glycol is best?

American Chillers recommends Inhibited Propylene Glycol which works as an anti-freeze, but also includes rust inhibitors and other additives that keeps your pump seals lubricated and fluids and chilled water system running in optimal condition. Other glycols may be acceptable.

NEVER USE AUTOMOTIVE OR RV ANIT-FREEZE IN CHILLERS.

NEVER USE GLYCOL IN COOLING TOWERS.

Glycol will reduce chiller capacity.

Questions about what glycol concentration and/or type to purchase? Contact and American Chillers sales engineer for assistance.
