The DM range of watermist nozzles has been stringently fire tested by the Building Research Establishment.
BRE GLOBAL at Watford, UK.
Dualmist can supply Nozzles to the commercial standard BS 8489 and the published BS 8458 for residential and domestic applications. Significantly, the DM4R and DM4C Nozzles have now been accredited with LPCB Approval.
The design objective of the DM nozzle is to provide optimum coverage whilst utilising low-pressures and minimal water distribution. This is achieved by a unique concept of combining fine and course droplets which are disseminated evenly within the respective range of each DM nozzle.
The DM nozzle range is extensive and is typically provided via a closed bulb arrangement, although fire testing has proven that at fixing heights above 5 meters that the open DM3 nozzle with smoke detection activation is far more effective than a bulb activated commercial sprinkler component. DM nozzles are manufactured as standard in 304 Stainless Steel components with a Nickel Plated Brass Main Body.
An optional blow off cap is also available developed for both aesthetic appeal and as a protection device, available as standard in white.
