ClimaCO2 Pro400 uses carbon dioxide (R744), a natural refrigerant with a Global Warming Potential (GWP) of 1 and zero Ozone Depletion Potential (ODP).
R744 is non-flammable and is not subject to the HFC quota phase-down. This makes the system suitable for bus projects prioritizing lower refrigerant-related environmental impact and long-term refrigerant availability.
The transcritical CO₂ heat pump system provides both cooling and heating through a single rooftop HVAC unit.
A variable-frequency compressor adjusts operation according to system demand. In cold weather, the heat pump can reduce reliance on conventional electric resistance heating, helping electric buses manage the energy required for passenger cabin heating.
The integrated design is suitable for bus fleets operating across different seasonal conditions.
ClimaCO2 Pro400 adopts a compact rooftop structure designed for integration with electric bus bodies.
The system features a double return-air arrangement and optimized airflow distribution to support more consistent cabin temperatures. Its evaporator and condenser fan configurations are designed to deliver the airflow required for passenger cabin cooling and heating.
The rooftop configuration also allows bus manufacturers to incorporate the HVAC system into their vehicle layout and installation planning.
ClimaCO2 Pro400 incorporates a dedicated heat pump control system for cooling, heating and defrost operation.
The control system supports operating-condition monitoring and maintenance management. Pressure monitoring and pressure relief protection provide multiple levels of protection for the high-pressure R744 refrigerant circuit.
These features support reliable operation and system management in demanding bus applications.
ClimaCO2 Pro400 is intended for electric passenger transport applications, including:
Electric city buses
Intercity buses
Electric coaches
Airport shuttle buses
Public transport fleet projects
For bus OEMs and vehicle integrators, the final HVAC configuration should be matched to the vehicle dimensions, electrical system, operating climate and required passenger cabin performance.
