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

Driver’s zone A/C simplified

We have quickly responded to the call for a maintenance- and user-friendly driver’s zone air conditioning unit that is easy to install. The result is the Citysphere S, which is based on our successful Citysphere model. By virtue of its compact dimensions and existing application interfaces, installation is astoundingly simple.

Low life-cycle costs

  • High lifetime through EC fans
  • High durability by semi-hermetic compressor
  • Easily accessible for service work

Easy Installation

  • Compact system pre-filled with refrigerant
  • Installation or retrofitting in a single day

Environmentally friendly

  • Noise-optimised operation compared to predecessor model Easysphere

Comfort

  • Constant cooling performance

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
