All- electric, intelligent energy management
The all-electric REVO ®-E rooftop unit for hybrid, electric, and trolley buses is characterised in particular by intelligent energy management, i.e. demand-oriented production of cool air depending on the available energy, and special compressor integration. The extremely compact electric compressor is located on the roof and not, as hitherto, at the rear of the vehicle. This has obvious advantages and due to the integration of all refrigerant-conducting components the closed system is more efficient, leak-proof and virtually maintenance-free.
Low life-cycle costs
- Low maintenance costs due to hermetically sealed refrigerant circuit
Comfort
- Controllability and intelligent integration of all electrical components
- Off-board power supply possible
- Cooling of traction battery possible
- Suitable for hot countries
- Use as a heat pump possible
Easy Installation
- No installation of refrigerant pipes because of integrated compressor
Reach
- Demand-responsive cooling output depending on available energy resources
Environmentally friendly
- No leakages because of hermetically sealed refrigerant circuit
- Patented vibration isolation of the compressor for less noise in the passenger compartment
Other features
- Patented vibration isolation of the compressor

Designed for the city
Valeo has developed an innovative and at the same time elegant climatic concept specially for city buses. With the new Citysphere air distribution system passengers are guaranteed a comfortable climate in the bus interior. Its low life cycle costs, together with maintenance free AC circuit, user friendliness and simple installation make the roof-top unit an efficient solution for many different applications.
Low life-cycle costs
- Low added fuel consumption
- Very low maintenance and service costs
- Long service life through brushless EC-blowers
Environmentally friendly
- Low weight reduces CO² – emissions
- Low noise emissions
Comfort
- Windchill-effect: combination of gentle cooling and air movement along the comfort line
- 15 % fresh air
- Optional heating with PTC-heating element
- Conforms to the requirements of the VDV guideline 236/1
Easy Installation
- Simple installation in hatch opening possible
- Pre-filled refrigerant circuit
- No installation of refrigerant pipes because of integrated electrical compressor
Reach
- Maximization of reach through reduced weight
- Low energy demand with stepless-regulated compressor
Other features
- Can be used also in hybrid and alternative bus drive concepts

Integrated air conditioning systems
Integrated full air conditioning system: Using its expertise in heating, ventilating and cooling, Valeo assembles a complete air conditioning system from the components air conditioner, parking heater, convectors, frontbox and skylight. The interplay of these elements guarantees a pleasant and consistent interior environment. Split-type units are always customized solutions which can only be implemented in close cooperation with bus manufacturers.
Aquasphere – heating and cooling by water circulation
- Highest level of comfort
- Individual weight distribution
- Free design of the outer contours of the bus
- High level of environmental compatibility due to less refrigerants
- Designed as a split-type unit, pre-filled with refrigerant
- Conventional integrated split air conditioner
- Individual weight distribution
- Refrigerating capacity from 17 to 54 kW
- Option of fresh, mixed or circulating air operation
Lightweight with simple installation
The REVO®-E Global is supplementing Valeo’s 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.
Low life-cycle costs
- Low consumption of energy due to 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
Easy Installation
- Easy installation on the bus roof from the inside or top
- Fast gluing due to integrated seal below the unit
Driving range
- Maximization of the range due to the low unit weight
- Optimized power consumption
- Variable regulation of the PTC heater
Other features
- Integrated compressor, no installation of refrigerant lines necessary
- Designed for R 134a & R 407C
