General Air Products offers a complete selection of standard and custom water cooled chillers. The water cooling process is typically done with loop chilling from chiller to process and in return offers continuous or intermittent cooling to any fluid-cooled process or sensitive instruments or machines. Water cooled chillers are available in capacities from 1 ton – 60 ton capacities. For specific heat removal requirements please contact our experienced support personnel at 1-888-863-7389.

Water Chiller Maintenance Requirements

  • Keep cooling and condenser fluids clean (7 pH range).
  • Regular electrical systems checks
