Valeo is committed to developing solutions for greener mobility and is a world leader in technologies to reduce CO2 emissions. 

From October 7 to 12, 2023, Valeo will be at Busworld Europe, the world’s largest event for buses and coaches taking place in Brussels, to showcase its innovative thermal management technologies for buses of all sizes and drive types.

Valeo is committed to developing solutions for greener mobility and is a world leader in technologies to reduce CO2 emissions and improve comfort on board buses and coaches. At Busworld Europe 2023, Valeo will focus on thermal management systems for buses worldwide – thermal comfort without compromise, maximum safety, and fleet-efficient solutions with zero emissions.

The shift towards low-carbon mobility and subsequent fast-growing market share of electrically powered buses has a significant impact on vehicle development and powertrain-related systems, including heating and air conditioning systems.

The fast-growing electrification of mobility – particularly in public transport – requires high-performance mobile energy storage systems that enhance travel comfort. In Brussels, Valeo will showcase its E-Cooler solution, allowing a range of battery temperature management models with a maximum cooling capacity of 10 kW, an optimal solution for a wide range of applications. Depending on the requirement, the E-Cooler protects the battery from overheating during charging and discharging and cools it while driving at higher outside temperatures and heavy loads. An additional heating function even warms up the sensitive batteries if necessary to restore the optimum temperature range.

Moreover, with limited electrical energy available from traction batteries, innovative and efficient HVAC solutions for buses are needed. A strategic leader in this market, Valeo’s innovations provide a comfortable interior climate for passengers and efficient solutions for fleet owners whatever the weather conditions, the size of the vehicle, its powertrain type, the mode (urban, suburban, or long-distance), and the duration of the journey.

The all-electric rooftop air conditioner REVO®-E HP R744, Valeo’s latest air conditioning system for buses with alternative engines will be presented at Busworld 2023. With a compact, reversible heat pump, this system cools and heats the interior of the electric vehicle efficiently and with low energy consumption. The unique dynamic de-icing on demand enables energy-saving heat pump operation even at cold outside temperatures lower than 5°C. The system is operated with the natural refrigerant R744. The chemical properties of this refrigerant and the specially developed control system enable it to be used at ambient temperatures from -20° to +50°C. The electronic control includes holistic thermal management with its own developed software, which always operates the system at the optimal operating point. This means that the cooling/heating capacity is generated according to demand and available energy so that the maximum coefficient of performance is always achieved.

The system impresses with a further significant reduction in noise emissions and weight, as well as a simplified refrigeration circuit. The integration of the compressor made it possible to achieve a compact system design, low refrigerant charge, and low energy consumption. The refrigerant circuit is maintenance-free, and durable components ensure low life cycle costs. The integrated battery cooling module keeps the battery at a constant temperature, which extends its service life and ensures greater efficiency. The new REVO®-E HP R744 has the same interface as Valeo’s REVO® classic system. For the vehicle manufacturer, this offers the greatest possible flexibility in installation and product mix. The system is a “plug & play” unit that can even be delivered to the customer pre-filled.
