Foam Proportioner

INTRODUCTIONP roportioners are designed to introduce a controlled flow of foam concentrate into a pressurized water stream. They provide an inexpensive foam proportioning means for systems requiring fixed flow rates and where available water supply pressures are adequate. Depending on specific foam systems design, line proportioners may operate with inlet pressures as low as 80 psi (5.52 bar).

Foam Proportioner

INTRODUCTION

INTRODUCTIONP roportioners are designed to introduce a controlled flow of foam concentrate into a pressurized water stream. They provide an inexpensive foam proportioning means for systems requiring fixed flow rates and where available water supply pressures are adequate. Depending on specific foam systems design, line proportioners may operate with inlet pressures as low as 80 psi (5.52 bar). The flow rate and operating pressure required at the foam making device are of primary importance in determining the required line proportioner inlet pressure. The line proportioner must match the flow rate of the foam making discharge device. Line proportioners can be used with all types of foam concentrates. The proportioners are available in a wide range of sizes for fixed foam system applications. These applications also require an atmospheric foam concentrate storage tank as shown in the typical Line Proportioning System schematic. Typical applications include use with fixed systems for protecting flammable liquid storage tanks.
