Catalog HIC
Danfoss offers various pre-engineered HICs, including fan drive, motor mount, spreader, and traction control solutions. These systems accommodate a wide range of flow and pressure ranges to match specific motor capabilities.
Fan drive features and benefits
- Six pre-engineered hydraulic integrated circuits (HICs) available to provide speed control and reversing for hydraulic modulating fan drive motors in open-circuit hydraulic fan drive systems.
- Various frame sizes and options available
- Variable piston pump or fixed pump circuits
- Over-pressure protection and anti-cavitation
- Viton O-rings
- Proportional fan speed control enables electronic matching of fan speed with cooling demand
- Reversing function enables purging (declogging) of coolers and radiators
Traction control features and benefits
- Efficient drive solutions on vehicles where one pump drives multiple motors
- Solutions available for two- and four-motor systems to deliver equal flow to motors once actuated, preventing wheel spin and excessive motor speed
- Custom bypass valve provides extremely low pressure drop with traction control dis-engaged, improving system efficiencies and reducing heat
- LFB12 flushing block assists in removing contamination and cooling oil, helping sustain high-quality working fluid in a hydraulic transmission circuit
Applications
- Agriculture
- Construction

Motor mount features and benefits
- Direct mount to motor provides optimum control at load
- Pre-work enables proper assembly and mounting to motor
- Mounting bolts and O-rings included
- Pre-testing to NFPA test standards enables robustness on your application
- Designed to match technical capabilities of motor
- Available designs include counterbalance, cross-port relief, bypass solenoid, and shock valve with anti-cavitation protection
Spreader features and benefits
- Load-independent flow control for two functions
- Commonly used for ice and snow control on sand/salt spreader vehicles
- Detented hand knob with minimum and maximum stops and 11 positive positions provide easy adjustment
- Dual control of two actuators, typically auger and spinner
- Pressure compensation for load-independent flow/speed control of motors
- Manual or electrical control for unloading
- Load sensing capability for open-circuit piston pump circuits (SPR-2FFLC12)
