BSPL will present the BOSCH Rexroth Fan control for hydrostatic fan drive systems on INTERNATIONAL BUS AND COACH TRADE FAIR (FIAA) on 23-26th of May in Madrid.

The task of a hydrostatic fan drive is to use controlled air movement to carry off the dissipated heat from the combustion engine arriving at the radiator. Here the drive serves to ensure optimal engine and combustion temperature. Intelligently controlled fan drive systems thereby help to maintain the legal emissions directives while saving energy. How? Controlled by highly developed sensors, they provide cooling based on the measured temperature to consistently reduce operating costs. No more or less cooling than needed – regardless of whether in on- or off-highway applications.
