Proportioner for Bladder Tank

Proportioners

The fixed ratio proportioner is designed to maintain a constant ratio of foam concentrate in foam systems. The product is designed for use with low-viscosity foam agents and has a minimum and maximum flow rate ratio range of 1:6. This range can vary depending on the type of foam agent used and specific minimum or maximum flow rates on a given diameter basis. To ensure proper mixing, at least five pipe diameters of straight pipe are required before and after the mixer. The proportioner operates on the principle of reverse pressure and consistently delivers foam from the foam tank or pump to the foam installation through a specified hole diameter. The proportioner ratios the foam at %1-%3-%6 concentrations. Commonly used components include sprinklers, nozzles, monitors, foam makers, and foam chambers. Each fixed ratio proportioner must be accurately calibrated at the factory.
