COL Series

COL Series


Hydraulic Oil Cooling

Cooling Medium





Air Cooled / Brazed Aluminum

The COL Series is an air cooled off-line fluid conditioning system utilizing reliable and high performing screw pump technology for independent cooling and filtering of system oils.  Choose the standard brazed aluminum P-BAR plate and bar core technology or the optional T-BAR core for high viscosity fluids.  Other options include cartridge style in-line filters and thermostat temperature sensors.

Consult catalog for additional sizes and technical information.


3D Model Coming Soon.

Our 3D Product Configurator will allow you to build up the cooler with specific options that are required for your application, view what you have created in 3D, then download the model directly into your format to complete your modeling project.
