REVO ®-E Global

All-electric unit for e- and hybrid buses

The REVO®-E Global is supplementing our range of all-electric rooftop air conditioning units and is specifically oriented to the demands of the global markets. A special emphasis was placed on lightweight construction, performance and simple installation. In addition to heat pump technology, customers also have the option of PTC heating and battery cooling.

Highlights

Low life-cycle costs

  • Low consumption of energy 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

Environmentally friendly

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

Comfort

  • Cooling capacity up to 33 kW
  • Heating with PTC heater or heat pump possible as an option
  • Tropical version: High cut off temperature of 55°C

Range of driving

  • Range of Driving: -20°C to +50°C
  • Maximized range due to reduced system weight and highly efficient heat pump down to -10°C (R407C)
  • Variable regulation of the PTC heater
  • Automatic de-icing function for energy saving heat pump operation at cold outside temperatures < 5°C
  • Flexibel and efficient power output due to infinitely variable compressor and fans
  • Electronic expansion valves (EEV) with Valeo control units for efficient operation with optimum high pressure control (optimal COP control)

Others

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