FireDos has once again proven the capability of its foam proportioners, passing FM tests with impressive results. The latest models, optimized for high-viscosity foam concentrates, have exceeded previous performance levels, setting them apart in the market.
These advanced proportioning systems can now accurately mix foam agents with higher viscosities than their predecessors. Achieving FM-approved viscosity values for “Variable Viscosity Foam Proportioners,” these models ensure precise mixing of foam concentrates with water for viscosities below the tested limits.
A “Variable Viscosity Foam Proportioner” allows for accurate blending of both low-viscosity (Newtonian) and high-viscosity, pseudoplastic foam agents. This flexibility is maintained within tested flow rates and back pressures, ensuring a constant proportioning rate.
Improved Viscosity Performance
Recent FM test results reveal that FireDos proportioners not only outperform previous models but also surpass the viscosity capabilities of FM-certified competitors. The new models show a certified viscosity increase of 12%, as of December 2024, setting a new industry standard.
Efficient Performance with Low Pressure Loss
FireDos proportioners stand out for their low pressure loss, even when working with high-viscosity foam concentrates. Unlike many proportioning systems that experience significant pressure loss with such agents, FireDos maintains exceptional performance, even at maximum extinguishing water flow, as verified by FM tests.
FM-Certified Flow Meter for Precision
FireDos also offers an FM-certified electromagnetic flow meter to measure foam agent volume flow. Installed on the return line, this device ensures reliable flow measurement and accurate proportioning rates. Paired with a calibrated tachometer, it provides estimations of extinguishing water volume flow in the range of 20% to 100% of the maximum flow rate.
Conclusion
FireDos continues to push the limits of foam proportioning technology. With FM-certified high-viscosity foam concentrate handling, low pressure loss, and precise flow measurements, FireDos proportioners offer superior performance and versatility, meeting the increasing demands of fire suppression systems worldwide.
