Angus Foam/Water nozzles are open, air aspirating discharge heads manufactured in stainless steel and designed for installation as part of an engineered fire protection system. They are designed to be used in conjunction with any of the Angus Fire Integrity range of foam concentrates such as AlcosealC6, TankmasterC6 and Tridol C6 Ultra.
The Angus K40 and K20 foam water nozzles are designed for applications where a low expansion foam application is needed followed by a period of water cooling. The nozzles are designed in such a manner as to produce a very similar spray pattern with foam and water. The K40 is designed to meet the 6.5 litres/m2/min application rates of NFPA spacing requirements and the K20 is designed to give an application rate of 4.1 litres/m2/min.
The K20H is a nozzle especially designed to provide foam/water protection for spray rings on bulk storage tanks. The K20H is mounted in a horizontal position, typically 250mm away from the tank wall and 700-900mm below the top of the tank shell.
The Tanker Loading Bay nozzle comes in two designs. The HL nozzle is designed for mounting above the tanker loading bay, to protect the top and sides of road or rail tankers. The LL nozzle is designed to complement the HL, by throwing foam underneath the tanker to protect the tyres and underside of the transport.
