In most conditions, Arctis(TM) Two-Speed Fan Drives are powered by eddy current, minimizing operating noise while maximizing available horsepower for auxiliary systems. When vehicle needs more cooling, fan drive springs actuate to run fan at full input speed. Featuring high torque clutch package and large air chamber for full disengagement, drives are suited for medium-duty trucks, buses, severe-service vehicles, and rear-engine cement mixers.

Fan Controller regulates RPM according to real-time demand.

info@productnews.com (ThomasNet News) — Mon, 05 Oct 2009 08:26:57 -0500

To ensure required linear air velocity is maintained despite external influences, C-600 controls and modulates fan RPM based on real-time air velocity and/or temperature measurements. User-programmable air velocity and temperature set points are leveraged to increase or decrease fan RPM, and I²C- or UART-based communication to host system can relay real-time information. If cooling fan is unable to generate desired flow requirement, controller initiates low-flow alarm to system.

Hydrostatic Fan Drives feature gear motor/pump design.

info@productnews.com (ThomasNet News) — Mon, 14 Jul 2008 07:41:19 -0500

Incorporating F Series pump and motor technology, Hydrostatic Fan Drives work in range of ambient temperatures from -40º to 212ºF. Units dissipate heat transferred by engine coolant as it flow through radiator. For moderate fan outputs of up to 20 kW, systems incorporating hydraulic fixed displacement pump with bypass control represent best solution. Applications include construction machines, agriculture and forestry vehicles, and road and rail vehicles.
