Passenger Coaches
Locomotives
MRVC 2TR Tower AC
The microprocessor-controlled, Roof-Mounted Air Conditioning Packaging Unit (RMPU) serves to maintain passenger comfort within the coaches by regulating temperature and humidity levels. Based on ambient temperature conditions, the operational modes of heating, ventilation, cooling, and dehumidification can be selected via the Human-Machine Interface (HMI) panel. Microprocessor controlled, Roof mounted Cab AC Unit maintains comfort for the driver inside the cab by controlling the temperature and humidity level. Depending on ambient temperature, the unit can be operated in Auto and Manual mode.
