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.
Benefits
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

Our Digital Displacement® pump technology is a fundamental innovation. It utilizes a radial piston machine which enables cylinders in real time, using ultra-fast mechatronic valves controlled by an embedded, intelligent computer. This makes our pump highly controllable and extremely efficient. The result is lower energy losses, increased productivity, and faster response time.
