Fan Drive Systems

Traditional fixed drive cooling systems will soon be a relic of the past. Machine design requirements, including fan drive systems, just got tougher than ever – due to Tier IV and Stage IV engines which must be in place by 2012. The new engines are bigger, and running hotter, with a 5-10 percent loss of power over previous generations. There’s a greater need for cooling – not only due to increased heat rejection, but also to control the temperatures in the engine, to meet both the emissions limits and fuel consumption requirements. On top of that, designers are facing lower engine efficiency. Quite a machine design dilemma, but we’re ready to help.

Sauer-Danfoss' proportional control, variable speed fan drive systems are engineered to enhance the performance of future generations of machines. We will collaborate with you to deliver a solution that efficiently cools on demand and recovers up to 50 percent of the engine power loss of emission-compliant engines. We’ve taken decades of experience in fan drives off highway to design robust systems that meet specific requirements of machines in a broad variety of applications – employing a combination of PLUS+1™ microcontrollers, gear pumps and motors, and HIC cartridge valves.

We’ll work to reduce the total cost of ownership with a system that’s smarter, more efficient and better supports fuel economy while redirecting available power to your work functions, even improving operator comfort by reducing noise. Today, controlling the economics of operation is an absolute must.

We’ll also work with you every step of the way. Our Design Guidelines contain helpful background information and a System Design Parameters form. The design process begins by simply completing this form and submitting it to a Sauer-Danfoss representative. Complete what you can and we’ll take it from there. We’re ready to employ systems expertise and products to maximize the efficiency of your cooling needs.
