What is MT4?

Marioff HI-FOG MT4 is the a water-mist system, propelled by an Electric- or Diesel-powered pump unit.

Powered by electricity or diesel, the MT4 is capable of long discharge duration with constant pressure.

MT4 system is actuated either manually or automatically. Marioff HI-FOG MT4 was tested for fire-righting ability according to the

International Maritime Organisation (IMO) requirements and for component* qualities to the satisfaction of FM (USA), VdS (Germany), and VNIIPO (Russia).
