Schaltbau Alte develops and manufactures heating, ventilation and air conditioning (HVAC) systems for train carriages and driver cabs that meet the strictest of international railway standards.

Depending on individual customer specifications, the systems can be designed as compact or split units and installed either on the roof of the train or below the floor. The Schaltbau Alte Control Unit ensures optimal performance and efficiency due to the frequency regulation of the compressor. We can install reciprocating, screw- or scroll-type compressors, depending on the application. The HVAC unit can be adapted to operate in extremely hot or cold climates as well as in high humidity or very dry, dusty environments.

We comprehensively test the systems in our own company laboratories, including tests for capacity, efficiency, noise level and reliability. Most simulations and tests are performed in-house. The company’s engineering services include:

  • 3D models
  • Finite Element Analysis (FEA)
  • Failure Mode and Effects Analysis (FMEA)
  • RAMS and LCC studies
  • Capacity and reliability studies in our own climatic chamber
  • ENV/REG/EMC tests
  • Detailed documentation
  • Characterisation
