helideck diffs system

matre diffs consist of matre foam skid and matre pop-up nozzles. when activated, the system will extinguish a major spill fire on the helideck within 15 seconds. several onshore projects have also seen the benefit of implementing matre diffs – e.g hospitals and similar institutions with helidecks.

matre diffs is designed in compliance to all applicable standards and regulations (cap437, normam27, icao, nmd, norsok). matre dual agent hose reel ( dahr ) is a compact, combined water / foam and dry chemical hose reel that is intended for manual use against smaller fires on and in the vicinity of helicopter decks. matre standalone diffs is developed and designed specially for existing nui platforms on the uk sector according to cap437 appendix d.  matre diffs for yachts is a compact skid unit designed to insert an exact rate of foam concentrate directly into the firewater.

the best way to meet all fire safety requirements and to afford the maximum fire protection for helicopter crew, passengers, building occupants and third parties adjacent to the building is to install a diffs unit to the helipad. it is then piped to multiple nozzles which are distributed evenly across and installed flush with the helipad surface. unperforated steel, concrete and aluminium helipads require the use of aff foam as the fire-fighting agent but for the enhanced safety™ helipad which contains a built-in, automatic fire suppression system, a water-only diffs is allowed by ukcaa cap and icao standards. this system differs from existing ones in that it is sensor activated for automatic operation, is fully fire tested in accordance with 2008/2009 standards and latest civil aviation codes. the system overview here relates to a foam diffs unit; a water diffs unit is essentially similar but somewhat simpler in configuration/hardware. the corrosion resistant spray nozzles are spaced evenly across the helipad and sit flush with its surface to provide an optimal and even coverage of the helipad surface.

the unit is capable of being activated either manually (by way of the remote manual stations) or automatically (by way of uv/ir or visual flame detectors). upon detection of a fire via the detectors, or on manual activation, a foam-water mixture will be released through the deluge valve-foam inductor unit, through the firewater piping network and to the spray nozzles. the entire system has been tested and approved in accordance with ukcaa cap437. in november 2008, senior representatives from international organizations including the uk caa and members of the icao heliport design working group attended live fire tests on the xe enhanced safety™ helipad with a diffs capability. the tests were organized by aluminium offshore and the overwhelming response from all representatives in attendance was support for the passive helipad with diffs option as a world best practice for helipad fire control. in 2016, the first edition of cap1264, standards for helicopter landing at hospitals, draws a similar reference to cap437 regarding the use of water as firefighting medium for diffs on a passive fire retarding helipad.

diffs system is primarily used as a firefighting system for helipad / helideck. based on the system configuration, diffs can be set to operate automatically the foam diffs system consists of an electric operated deluge valve, pop up spray nozzles, remote manual stations, uv/ir flame detectors, deluge valve release matre deck integrated fire fighting system (diffs) is specially developed to extinguish fire on helidecks. matre maskin as delivered its first diffs in 1991,, cap 437, cap 437, diffs nozzle, matre diffs, deck integrated fire fighting system.

a deck integrated fire fighting (diff) system is an effective fire suppression system that is normally the primary firefighting system on a helideck. the compact design of the system also allows it to be easily installed in storage areas and hangars used for aircrafts and helicopters. diff system is primarily used as a firefighting system for helipad / helideck. based on the system configuration, diffs can be set to operate automatically as an alternative to the standard firefighting equipment, we offer deck integrated fire fighting system (diffs). this system consists of a network of pipes diffs is an acronym for “deck integrated fire fighting system”. a diffs unit consists of a skid which processes firewater inflow to output foam or water., foam system, fire suppression system, foam suppression system, onboard fire suppression system, inert gas fire suppression system, tank fire suppression systems, gas suppression system, design of sprinkler system in fire fighting, fire protection system design, gas suppression system design.
