Auxiliary Power Unit

With the assistance of our expertise, we are capable of manufacturing and supplying of Auxiliary Power Unit in Hyderabad, Telangana, India. It is a self-contained system with its own small diesel engine coupled to low capacity compressor and alternator to maintain main reservoir pressure, charge battery, operate driver cabin HVAC system and other small loads as per customer requirement. The main engine is started only when the locomotive is actually required for movement or traction.

The control system on the locomotive continuously monitors the locomotive battery status and other important parameters like MRPR, Loco IDLING status, Engine temperatures etc. If the loco idling time is more than 10 minutes, the system shuts down the main engine and run the APU engine.

APU has a baby compressor, which produces compressed air and feeds to locomotive main reservoir to compensate the formation leakages.
