Liebherr tests HVAC energy optimization package with Alstom and Hamburger Hochbahn

Significantly rising electricity costs in the public transport sector are a challenge for both, the operators as well as the rail transport vehicle manufacturers. In order to provide a solution, Liebherr-Transportation Systems, train manufacturer Alstom and operator Hamburger Hochbahn have jointly developed a program to make Liebherr’s existing advanced heating, ventilation and air-conditioning (HVAC) systems for the DT5 fleet even more energy efficient.
