Heating-, ventilation- and air-conditioning units for high speed train application

Technology

With extreme outside temperatures of up to 60 °C and occasional sand gusts, the HVAC systems must work reliably to enable comfortable travelling. Liebherr's HVAC technology solution ensures a constant, agreeable climate on board and can keep the inside temperature in the saloons below 23 °C - even with full passenger capacity. The HVAC saloon units offer for the pressure-protected high-speed train application an innovative redundancy concept and are equipped with a best-in-class air filtration system.
