ANSUL KR-S/M4 Dual-Expansion Foam Handline Nozzle 120 gpm (454 Lpm) - 415986

ANSUL KR-S/M4 Dual-Expansion Foam Handline Nozzle 120 gpm (454 Lpm) - 415986

Two sizes are available for nominal flow rates of 60 gpm and 120 gpm at 100 psi (227 Lpm and 454 Lpm at 6.9 bar). Foam solution is sprayed through the nozzle and as air is being drawn into the nozzle, foam is produced in the tube. Each nozzle has a ball shut-off valve. The nozzle tube is constructed of stainless steel with a tough polyurethane handle providing optimum protection against corrosion. Although the normal operating pressure is 75 psi to 100 psi (5.2 bar to 6.9 bar), a minimum operating pressure of 45 psi (3.1 bar) is acceptable. Foam concentrate is usually proportioned to the nozzle using the matching ANSUL Model Z eductor.

Features

• Two foam handline nozzles in one
• Change over from medium- to low-expansion foam in seconds
• Non-corrosive materials
• Pressure gauge equipped
• Easy-to-operate ball shut-off valve
• Good foam quality with pressure of 45 psi (3.1 bar) and greater

Application

ANSUL KR-S/M dual-expansion foam handline nozzles can be used with various types of foam agents. In particular, they are recommended for use with the following foam concentrates for typical applications as noted:

• ANSULITE 3X3 LV Foam – As a vapor suppressant foam for various hazardous fuming compounds including oleum and chlorosulfonic acids. ANSULITE 3X3 LV is also effective with these nozzles as a fire suppressing foam both for flammable and combustible hydrocarbon and polar solvent (water miscible) fuels.
• JET-X High-Expansion Foam – As a fire suppressant for hydrocarbon fuel products when proportioned at a 2–3% concentration in the medium-expansion setting.
• SILV-EX PLUS Class A Foam – As a high-performance fire suppressant on difficult Class A fuel fires including wood, paper, coal and rubber. The dual-expansion nozzles, when combined with SILV-EX PLUS foam proportioned between 0.5% to 1.0%, provide longer surface wetting with reduced risk of ignition/re-ignition. Additionally, the concentrate creates a foam blanket which provides an insulating barrier between the fuel and air.
