Off-highway mobile machinery OEMs and distributors can choose from six pre-engineered Hydraulic Integrated Circuits (HICs) designed to provide speed control and reversing for hydraulic modulating fan drive motors in open circuit hydraulic fan drive systems. The program includes:
• 40, 80, and 120 LPM Frame Sizes
• Variable piston pump or fixed pump circuits
• Over-Pressure Protection / Anti-Cavitation is standard
• Viton O-rings are standard
Features
•  Proportional Fan Speed Control:
- Electronically match fan speed with cooling demand
- Conserve engine power and fuel for the majority of operating conditions - as compared to non-proportional systems
•  Increased design flexibility:
- The compact HIC valve can be placed in the most suitable location on the machine
- Minimize fan system pressure losses when choosing the optimal fan drive HIC size for the application
- Internal and external reversing pilot options available (40 LPM & 80 LPM )
- Drain port included on all models for motor case drain
- Robust IP69K Deutsch coil options available for all three sizes
•  Increased productivity:
- Fan is reversible to purge (de-clog) coolers and radiators
- Prevents overheating with purged cooler
- More power available for useful work when radiator is not clogged
•  Reversing function allows you to:
- Purge (declog) coolers and radiators
- Prevent overheating
•  Automatic cleaning sequence programmed using PLUS+1™:
- Manual or Automatic activation
