This product has been designed specifically for Hydraulic Fan Drive control and gives the user new levels of automation while integrating seamlessly in a typical discrete cooling system.

It can control a hydraulically driven fan proportionally or in an ON/OFF manner based on user settings, system configuration and cooling needs with three 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.

HFS Product Features:

  • Pre-written Graphical User Interfaces for all modules
  • Operates with all OEM electro-hydraulic equipment
  • Sealed and protected to >IP67 ( NEMA 6P )
  • Unique 'Solid' potting with flame retardant materials
  • Up to 3 channel discrete thermistor input capability
  • Uni-direction fan control
  • Suitable for new OEM build or Repower / Retrofit / Upgrade applications
