Concentric AB-FAN DRIVE-US-2011-6 2 Concentric Hydraulic Fan Drives The Concentric fan drive offering includes systems that range from simple to complex. System designers can choose the option best suited to the design criteria driving each vehicle and cooling system project. The fan drive systems and components within this catalog are not all inclusive regarding system solutions. For instance, the fan drive system may also be integral to the hydrostatic drive charge pump system, the brake charging system, the pilot control valve system, etc. Concentric has provided fan drive system solutions for all these and many other types of integrations. Solutions from the vehicle perspective are one of our core competencies. We have many other products (pumps, electrohydraulic power systems, valves, etc.) that may be applicable to your application. Therefore, if you do not find the specific solution within this catalog, contact Concentric for assistance. We will engineer a solution specifically for your vehicle.

Vehicle Host Control ECM WM900 Motor W900 Pump Reservoir The demand for increased energy savings, reduced emissions and reduced noise in vehicles is requiring that vehicle engineers question traditional design approaches and traditional systems. One area of focus on vehicles ranging from buses to excavators is cooling systems. Concentric fan drive systems offer significant advantages to cooling system designers when compared to traditional belt and electric fan drive systems. These advantages include: • Fan speed independent of engine speed • Precise control of coolant temperature • On-Demand cooling capability which eliminates excess power consumption • Reduced noise • Reduced emissions • Flexibility in cooling system design quality products for mechanical & fluid power jbj Techniques Limited, www.jbj.co.uk quality products for mechanical & fluid power ~ jbj Techniques Limited, www.jbj.co.uk UK distributor for Concentric Hydraulics
