New rooftop air-conditioning system for electric vans and minibuses from Webasto
The fully electric Cool Top 120-e air-conditioning system delivers up to 12 kilowatts of cooling power. It is suitable for electric vehicles with a 400-volt DC power supply, like minibuses, light commercial vehicles and ambulances. Thanks to its intelligent variable compressor control, it is very efficient and quiet.
Stockdorf – March 3, 2026 – The new air conditioning system from thermal technology expert Webasto has been specially developed for light commercial vehicles with electric drives and operates with voltages between 250 and 460 volts DC. Thanks to its high cooling capacity, it reliably ensures pleasant interior temperatures even in hot outside conditions and with a full load.
Measuring 1,605 x 1,290 x 300 millimeters, the air conditioning system is very compact in design despite its high performance and weighs only around 80 kilograms. It uses R1234yf as a refrigerant, which contributes to the system's environmental friendliness thanks to its low global warming potential (GWP). The system is delivered pre-filled.
Cool Top 120-e cools the vehicle, both when stationary and while driving. Once the target temperature has been reached, the variable speed control of the compressor automatically adjusts the output to the cooling demand. The system then operates at partial load, making it very quiet. A fresh-air function provides additional comfort in the vehicle when required.
The roof-mounted system can be integrated into existing vehicle systems via CAN bus or controlled via an optional Webasto control unit. Thanks to its plug-and-play design, installation and commissioning are very quick and easy.
The housing of the rooftop air-conditioning system can be painted in the color of the vehicle. Air outlets and ducts can be individually specified. The units are now available to order from specialist retailers, with a recommended retail price of 7,059 euros net.
