Ultralight 500-700 CO2 Heatpump
Roof compact air conditioner | Cooling capacity: 26,5 kW | Heating capacity: 21 kW
The most environmentally friendly and innovative way to air-condition electric buses
The Ultralight 500-700 CO2 heat pump is our holistic thermal management for electric buses - and a must for innovative and ecologically oriented transport companies.
It is operated with CO2 - a refrigerant permitted in the long term - and extracts the energy from the ambient air - thus increasing the range of the electric bus by up to 60%. The savings potential in service costs is enormous: it is around 70%. Thanks to the new energy carrier modules, the Ultralight 500-700 CO2 heat pump is very flexible: it can heat and cool buses simultaneously - and cool the batteries, for example, while simultaneously heating the passenger compartment.
Advantages
- CO2 heat pump
- CO2 is cheap and permanently available
- The system heats and cools simultaneously
- Environmentally friendly and recyclable material
