Foam Dosing System

Overview

Review of Foam Dosing System

Dosing foam system is one of the latest foam fire extinguishing systems, which is very popular due to its economical price, easy installation and convenient use. This system, which is known as the newest foam fire extinguishing system, does not require any external force to mix water and foam, and it uses water flow to supply the energy needed by the device. The foam dosing system is produced in two fixed and portable models.

The foam dosing system consists of a coupled pump and turbine. In this system, the power required to suck the foam from the tank is provided by the water turbine. This turbine is directly connected to the pump to provide the required power. As we have already mentioned, this system does not need any external power and to supply its energy, it uses the water flow in the system that moves towards the nozzles. In general, the foam fire extinguishing system includes various equipment such as blower tank, foam pourer, Portioner foam and so on.

Material of foam dosing system equipment

To use this system for a long time, it is better to choose equipment materials that have sufficient resistance. For this reason, the water turbine is made of aluminum body material so that it has less weight in addition to water resistance. In cases where salt water is used, it is better to use anodized aluminum or bronze or nickel aluminum bronze. Also, the material of the body of the foam pump is made of bronze so that it has good resistance against foam in the long term.

The valves and connecting pipes of this product are usually made of stainless steel, so that in addition to the proper resistance to foam, it does not add impurities to the solution.

Features and applications

Benefits of foam dosing system

As we said, the foam dosing system is a fire extinguishing system that uses foam as the main agent to extinguish the fire. This system includes equipment that produces foam and sprays or applies it to various locations, including fire hazard areas. The foam used in these systems is usually produced in two forms: cooling foam and encapsulating foam. Cooling foam extinguishes the fire by cooling the fire area and reducing the temperature. But the foam that creates the cover by creating a cover layer on the combustible surfaces, prevents its contact with oxygen and neutralizes the fire.

The foam dosing system is usually used in places where there is a high risk of explosion or fire with flammable liquid and gas materials, such as gas stations, chemical industries, power plants, airports, etc.

These systems usually work automatically and if heat or fire is detected, they spray foam in the desired area and extinguish the fire. But in order to use it properly and ensure its optimal performance, they need periodic maintenance and repairs.
