Ultralight 500 CO2 heat pump 2.0

Roof compact air conditioner | cooling capacity 20 kW | heating capacity 18,2 kW

The most environment friendly way of air conditioning electric buses

The Ultralight 500 CO2 heat pump is our holistic thermal management for electric buses - and a must-have for innovative and ecologically oriented transport companies.

It is operated using  CO2 – a long-term permitted refrigerant – and obtains energy from the surrounding air – this will increase the range of electric buses by up to 40%. The savings potential regarding service costs is enormous: it is at about 70%. Thanks to the new energy carrier module the Ultralight 500 CO2 heat pump 2.0 is very flexible: it can heat and cool buses simultaneously – and for example cool the batteries and heat the passengers’ compartment at the same time.
