Compromiseless fire protection.

The advantages of our compact diesel fire pump units: Space-saving with high performance, plug&play, no wiring required, reduced structure-borne noise and few interfaces.

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

  • Established processes and partnerships ensure 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, understandable and functional.

We are a system supplier and NFPA member.
