COLW Series
The COL Series 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 an 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.
Delta T Heat Exchangers is partnered with Thermal Transfer Products, a division of API Heat Transfer, to offer their pre-engineered heat exchangers. If you know your performance requirements, you can contact us by requesting a quote.
