Increased efficiency

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.


Increased efficiency due to variable flow piston pump

Reversibility inherent to the system with no additional plumbing

Has inherent zero-speed capability

Negligible risk of motor cavitation

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

Higher pump and motor pressure, power and life ratings

Fan speed independent of engine speed

Minimal reservoir requirements

Motor speed sensors available

Critical considerations

Charge flow required

Higher pump and motor cost

Motor thrust load capability must be calculated

Fan fails to minimum fan speed
