Frame Mounted Hydraulic Cooler

The THERMAFLOW SS600 hydraulic cooler is the original SS934. The SS600 and the SS934 have almost identical capabilities but the SS600 is a wider unit. It is a hydraulic cooler designed to be conveniently mounted on the frame rail just like the SS934. User preference is the only real difference between these two siblings. The SS600 hydraulic cooler will drive most 3″& 4″ product pumps and compressors, with options for multi-pump applications, it is able to support applications such as, chemicals, compressed gasses, food grade, crude oil, vacuum pumps and combo drives..

Model Options


Relief (R):

The standard relief valve offers pressure protection.

Directional Control (V):

A directional control valve allows for easy rotation changes or drive selection.


Electric (E):

The Electric fan motor option has a 12VDC cooling fan which is operated with a temperature control switch. This switch gets wired into keyed power. When the key is turned on, the switch will be ready to activate the fan when the oil temperature gets to 110°F. When the oil temperature falls to 105°F the fan will turn off.

Hydraulic (H):

The Hydraulic fan motor option has a fixed pressure compensated flow control that automatically cycles the fan “ON” when the hydraulic system is running and “OFF” when not running. This option comes plumbed from the factory.
