The Delta Hydroshield Water Curtain Nozzles are designed to quickly and efficiently establish a large Waterwall to protect the operative against heat, sparks, smoke and noxious gasses creating a safe zone from behind which firefighters are free to tackle the fire through the Waterwall with jet nozzles.The Hydroshield is also a highly effective nozzle for cooling neighbouring fuel storage tanks or combustible materials that are in danger of spread from the fire.Professional Firefighters have used the Hydroshield for many years and are now also widely used in the Industrial sectors, most commonly for building or plant protection on waste recycling sites and timber yards but equally effective on chemical sites, fuel storage sites and for multiple marine applications.
