chemguard high expansion foam generators produce large volumes of foam by coating a stainless steel perforated metal screen with a high expansion foam solution and expanding it by airflow generated by a water-powered fan. They are capable of producing finished foam with expansion ratios from 332:1 up to 891:1, depending on the model and operating pressure.
Typical applications include protection of aircraft hangars and high-hazard, hazardous materials storage facilities. They are also used to protect liquefied natural gas (LNG) facilities.
Liquefied natural gas (LNG) absorbs heat from the surrounding environment and forms a vapor cloud that is difficult to control or suppress by traditional fire suppression methods. Using high expansion foam helps to block the heat due to convection and thermal radiation.
In addition, the water content of the foam provides a valuable cooling effect to the flaming fuel. It is a safe, nonflammable, biodegradable, and water retentive solution for use in Class A and Class B fires.
Environmentally Responsible Foaming Agent
CHEMGUARD C2 2% High-Expansion Foam Concentrate is an environmentally responsible foam concentrate that consists of surfactant based polymers and a low odour, high water retentive base. It can be used to protect both indoor and outdoor environments from Class A and Class B hydrocarbon fires, as well as control and extinguish flammable liquid spills.
The UL Listed CHEMGUARD High-Expansion Foam Generator is a portable, water turbine powered system that requires a foam compound and pressurised water supply (4 bar minimum). It produces large volumes of foam with a variety of expansion ratios and can be controlled by an electric or battery operated fan.
