SFO 904 - FUEL OPTIMIZER
Description
An intelligent Fuel Optimizer unit optimizes the usage of Genset operations in Tele Communication towers in the event of mains failure condition. Instead of turning on the Genset immediately upon mains failure, it checks the Shelter Battery voltage condition as well as the Shelter Temperature before activating the starting of the Genset.
By the optimized usage of Genset, this unit will reduce fuel consumption. This unit can be smoothly integrated to any AMF panel currently installed in Telecom towers. It continuously monitors the EB.
