Propane-based heating-, ventilation- and air-conditoning system

Technology

This design marks a special milestone for Liebherr as the company is supplying for the first time a series-produced HVAC system using propane. The technical concept considers all relevant safety requirements. Propane as a refrigerant offers a natural alternative to conventional, environmentally harmful refrigerants. In addition, the system is easy to service and guarantees rail operators a reliable product solution with minimal down time.
