TPW MK3

The SKUM TPW MK3 Wide Range Proportioner operates by metering foam concentrate into the water supply line, precisely controlling the mixture of foam and water for effective fire suppression. Designed by Skum, this proportioner is specifically engineered for use with bladder tank foam-water sprinkler systems. It is FM Approved for use with SKUM AFFF 3% UG and SKUM ARC 3x3 UG Foam Concentrates, and UL Listed and USCG Approved for use with ANSULITE A336 USCG 3x3 AR-AFFF Concentrate. When installed in a closed head, wet sprinkler system, the proportioner automatically adjusts to varying water flow rates. As more sprinkler heads open, the proportioner increases the orifice size on the metering tube, allowing more foam concentrate into the water stream. This ensures proper foam proportioning across a wide range, from extremely low flow rates to high flow rates. The SKUM TPW MK3 Wide Range Proportioner is available in three standard sizes (6 in., 8 in., and 10 in.) and is designed to fit between two DN150 (6 in.), DN200 (8 in.) or DN250 (10 in.) DIN PN16 (ANSI Class 150) pipe flanges.
