Compact, eco-friendly and quiet.

Space-saving with high performance, plug&play, no wiring required, reduced structure-borne noise and few interfaces.

Our customers benefit greatly from the reduction to one single interface in order processing and significantly minimised effort due to:

  • Established processes and partnerships thatensure solution-oriented engineering and on-time material procurement.
  • Our technicians are highly competent, friendly and weatherproof when installing and maintaining our systems, including offshore.
  • Due to our close cooperation with international insurers, we always find a safe solution during inspections.
  • Our documentation is precise, easy to understand and functional.

We are a system supplier and a problem solver with VdS approval.
