Foam Guardian - Foam Concentrates Storage and Proportioning System
The FOAM GUARDIAN foam concentrates storage and proportioning complex is specially designed for use in foam fire-fighting systems at oil and gas production facilities, and chemical industries located both onshore and offshore. The FOAM GUARDIAN is designed for storing firefighting additives and enabling precise dosing in a wide range of water flows. The storage complex includes a storage tank of foam concentrate PROFIREX EPO (TU 25.29.1-007-65344199-2020), specially designed for interconnected use with a FIREMIKS proportioning system.
The PROFIREX EPO foam concentrate storage tank is designed for automatic fire suppression systems using low, medium, and high expansion foam in hazardous facilities that store the foam concentrate.
The PROFIREX EPO foam concentrate storage tank provides storage of the foam concentrate and ensures its’ timely supply to the automatic firefighting system by means of the FIREMIKS turbine-type proportioner.
The equipment integrated in the PROFIREX EPO foam concentrate storage tank enables both visual control and accounting of the amount of foam concentrate by means of a visual level meter and automatic control. A vibration level meter (optional) accounts for the amount of foam concentrate and can transmit signals to the fire control panel.
The impeller pump (optional) is integrated in the PROFIREX EPO foam concentrate storage tank and pumps the foam concentrate in a closed cycle, which ensures compliance with the conditions of foam concentrate storage.

ТFIREMIKS proportioner equipped with piston (plunger) type pump
The FIREMIKS turbine proportioning system is designed for high-precision mixing of liquid foam concentrates with fresh or sea water and is suitable for use in fixed and mobile installations.
The FIREMIKS proportioner is a fixed system which does not need a pressure tank. The FIREMIKS proportioner is connected to the PROFIREX EPO atmospheric foam concentrate storage tank. Structurally, the FIREMIKS proportioning system has two volumetric parts, one water motor and one concentrate pump, connected to each other through a direct drive coupling. With this solution the water motor acts like a combined flow meter/ drive for the foam pump, automatically achieving the correct ratio between water motor and foam pump without any external flow meters, foam pumps or orifices.
The water motor provides smooth rotation and volumetric proportional dosing. FIREMIKS dosing system provides stable operation of compatible firefighting equipment when using different types of foam concentrate and water.
The model range of the FIREMIKS proportioning unit with piston (plunger) pump for the foam concentrate is suitable for a wide range of flow rates. Normal and explosion-proof versions enable the proportioning complex to meet any fire production system’s requirements. Additional options make it flexible, easy to maintain, and simple to use (See Table 2).
The main technical characteristics of the FIREMIKS proportioning systems are shown in Table 1. The PROFIREX proportioning complex for firefighting systems has passed the Academy of State Firefighting Service of the Ministry of Emergency Situations of Russia’s voluntary certification procedures.
