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.

HFS-2 & HFS-2Q Product Features:

  • Pre-written Graphical User Interfaces for all modules
  • Operates with all OEM electro-hydraulic equipment
  • Sealed and protected to >IP68 / NEMA 6P (with weatherpack option)
  • Unique 'Solid' potting with flame retardant materials
  • Up to 3 channel discrete thermistor input capability
  • Uni or Bi-directional fan control
  • Suitable for new OEM build or Repower / Retrofit / Upgrade applications
