• High Country Tek (HCT)


The highly cost effective HFS-J has enough processing power and input output functionality when operating as a single control module to support a wide range of hydraulic fan system applications.

As with all of the HCT modules, the HFS-J is packaged in a small rugged enclosure and encapsulated in flame resistant resin to withstand extreme conditions in the harsh mobile operating environment. It can control a hydraulically driven fan proportionally or In an ON/OFF manner based on user settings, system configuration and cooling needs with J1939 CAN Bus communications for engine and temperature zone data Inputs, and / or two independent inputs (zones) that will interface with industry standard NTC, two wire thermistors. Two (2) switch inputs, suitable for over temperature switches, retarder switches and air conditioning clutch switches are also provided for added system flexibility.
