The THERMAFLOW assembly is designed to cool and filter the oil required to operate
your hydraulic system. The oil is cooled by forcing air across cooling fins on the heat
exchanger. This system utilizes either an electric or hydraulic fan motor to force air
across the fins. The fan motor options and control valve options are described below.

The Model 934 has 2 fan motor options, Electric or Hydraulic. The 934HV has
the Hydraulic fan motor option which 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.

Also, the 934HV unit has the optional control valve system installed. This control valve system will
allow the operator to start, stop, and change rotation of the product pump by simply
shifting the control valve. This control valve is integrally mounted and plumbed within
the cabinet to save frame rail space, lower installation times, and to reduce hose and
fitting costs.
