Bus Engine Cooling

The EEC (Electrical Engine Cooling) equipped with multiple Spal brushless fans consumes about 80% less engine power than the traditional single hydraulic or mechanical fan. Electrical fans are operated on demand at the required speed, optimizing the global efficiency of the cooling system. EECs with Spal fans will lead to fuel savings up to 10% and help noise management, avoiding any maintenance activity. On e-buses, multi fan array reduce power consumption of drivetrain and BTMS (Battery Thermal Management Systems) improve battery efficiency
