Meeting your demands

Danfoss offers a wide range of efficient fan drive systems. Below are the benefits and critical considerations you need to take into account as you determine the right system for your specific needs.

Benefits

Increased efficiency due to variable flow piston pump

Fan speed independent of engine speed

Reversibility inherent to the system with no additional plumbing

Has inherent zero-speed capability

Minimal reservoir requirements

Well known, closed-circuit technology for high-power applications

Negligible risk of motor cavitation

Higher pump pressure, power and life ratings

Critical considerations

Loop flushing required

Charge flow required

Higher pump cost

Fan fails to minimum speed

Over-pressure protection required
