Foam is the only proven fire fighting system against fire on heli-decks. Our systems are certified according to international standards.
SemDual is a manually operated unit, discharging dry chemical powder and AFFF foam.
It is built for the protection of a helicopter landing area to meet CAP 437 specification.
In operation, the dry chemical gives a quick knock down of the fire, and the water/AFFF foam mix gives cooling and a sealing surface to prevent re-ignition.
SemDual is connected to the firewater ring main system via a standard flange connection.
Correct mixing of foam is achieved through an in-line inductor.
