The demands placed on HVAC systems are more complex and differentiated than ever before, and present a new challenge to manufacturers. Rather than limiting ourselves to the development of individual components, we place emphasis on the integration and interplay of innovative air conditioning components, including newly developed control software, including for the strongly growing market for electronic drives. We call it “Entelligence”, currently the best solution for modern eBus climate.


Each innovation is put through its paces at the development and test centre in Gilching, Germany, where a large climatic chamber for overall system tests and numerous component test facilities, together with values obtained from the company's two test buses, provide information on the function and reliability of the air conditioning systems. Whereas air conditioning systems are tested at Gilching and the Spheros plant at Caxias do Sul, Brazil, there are further test centres for heaters, pumps and components in Neubrandenburg, Germany, and for hatch systems in Turku, Finland


Responsible use of energy and raw materials are also core issues for our customers. Aspects such as energy efficiency, fuel consumption and system weight are increasingly crucial for gaining customer orders. Ecological and at the same time economic thinking are a basis for long-term partnerships. Examples of our commitment hitherto to new, resource-saving and efficient solutions:

  • Reduction of weight (e.g. operation with aluminium components)
  • Use of recyclable material
  • Reduction in fuel consumption
  • Operation with alternative fuels or drive concepts
  • Lower emissions (noise, exhaust)
  • Alternative energy generation, e.g. solar electricity for fans
  • Vehicle energy economy
