REVO ®-E Global

All-electric unit for e- and hybrid buses

The REVO®-E Global is our latest global air conditioning development for buses with alternative powertrains, designed specifically to meet the demands of global markets. Particular emphasis has been placed on lightweight construction, performance and ease of installation.

In addition to heat pump technology, customers also have the option of PTC heating and battery cooling. To enhance riders' experience, the system cools and heats the interior of the electric vehicle efficiently and with low energy consumption. The system is a “plug & play” unit that can even be delivered pre-filled to the customer.

Highlights

Environmentally friendly

  • Safety against leakage due to the hermetically sealed refrigerant circuit
  • Noise emissions optimized

Low life-cycle costs

  • Low consumption of energy in the vehicle due to the low unit weight
  • Short dimensions allow space for battery system on the roof
  • Long duration due to brushless EC blowers
  • Nearly maintenance-free

Comfort

  • Cooling capacity from 21 up to 40kW
  • Heating with heat pump or PTC heater possible as an option
  • Tropical version: High cut off temperature of 55°C

Range of driving

  • Range of application: -20°C to +55°C
  • Maximized range due to the low unit weight and highly efficient heat pump up to -10°C (R407C)
  • Optimized power consumption
  • Variable regulation of the PTC heater
  • Automatic de-icing function on demand, for energy saving heat pump operation at cold outside temperatures < 5°C
  • Flexibel and efficient power output due to infinitely variable compressor and fans

Battery Cooling function and more

  • Integrated compressor, no installation of refrigerant lines necessary
  • Integrated plate heat exchanger for BTM
  • Designed for R407C
  • Design for R134a on demand
