Viscous fan drive technology
Precise thermal management that does so much more than keep engines cool.
In addition to regulating engine temperatures with razor-sharp precision, viscous-operated fan drives can produce lower emissions, decrease noise pollution, provide fuel savings and ultimately increase performance. The newest viscous drives also feature Cold-Start Disengagement™, which can help trucks and agricultural tractors warm up faster during cold conditions.
Advantages of variable-speed fan drives that use viscous technology
- Optimized cooling means more power to vehicle's wheels
- Reduced noise
- Decreased particulate matter release/lower CO2 emissions
- Faster engine and cab warmup with Cold-Start Disengagement™
How it works
This animation of Horton's latest variable-speed fan drive, the LCX, shows viscous cooling technology in action.
Applications
Virtually any on- or off-highway engine can benefit from viscous cooling technology. This includes heavy- and medium-duty trucks, agricultural tractors, vocational and specialty vehicles. LEARN MORE >>
Cold-Start Disengagement™
Cold-Start Disengagement helps engines warm up faster in the cold. Viscous drives with CSD hold oil in the reservoir while the engine is off, so the fan disengages up to 80 percent faster than standard viscous drives. LEARN MORE >>
