FECON Hydraulic Rooftop Oil Coolers

The difference with the coolers must do with install. Either the cooler gets installed after the control valve which would be no check valve or gets installed after attachment return, requiring a check valve.  Basically, the check valve makes the cooler a 1-way flow. The unit without a check valve is 2-way flow. It must be understood though, that a cooler with no check valve must be installed after the control valve. Generally, the return of the control or main valve will go to the inlet of cooler. The outlet of cooler will go back inline either to tank or a return filter all depends on the carrier. The units with the check valve are ONLY 1 way flow.
