COLW Series

Water-Cooled Cool Loop, Offline Fluid Conditioning System, Wall, and Floor Mount.

The COL Series Cooler is a water-cooled off-line fluid conditioning system utilizing reliable, high performing and low-noise screw pump technology. High efficiency is achieved by the utilization of the brand’s EK Series shell & tube heat exchanger.

Options include cartridge style in-line filters and thermostat temperature sensors. This series is ideal for independent cooling and filtering of system oils.

Features:

  • Utilizes a high efficient EK Series shell & tube (finned bundle) heat exchanger
  • Low to medium pressure applications utilizing low noise screw pump technology
  • Pump flows ranging 9.5 to 45 GPM (60 Hz) (30 to 140 LPM)
  • Standard SAE connections on customer-integrated ports (BSPP adapters available)
  • Optional cartridge-style filters with both visual and electrical bypass indicator options
  • Specifications
    • + expand all
    • - collapse all
