Features: mining Fuel inert gas bubble generating device, technologically advanced multi-functional latest mining Fuel inert gas bubble generating device, it can be readily observed oxygen content, and can adjust the gas composition, improved due to water power automatic protection device . Additional secondary combustion equipment so that it can maintain in the case of oxygen reduction of CO at a low level, the use of to import oxygen probe permanent use, you do not need to change. Mine explosion-proof switch, automatic ignition device. Operation is safe and easy to use. Is the most practical coal mine fire extinguishing devices. Using a combination of technology: Depending on the fire changes can be composed of different fire models, the use of a machine, is the most suitable coal mine fire extinguishing devices. This product is currently free expansion elongated, the new restructuring automatic leveling damping wheels. The machine made of stainless steel. Purpose and scope: mainly used for Fight large fires, coal mine rapid inerting fire zone, control gas explosion, reduce or eliminate residual fire resurgence, both burst fire resistance, but also play the latest technology and equipment of the isolated, choking fire , but also for warehouses, tunnels, petroleum, chemical, airports, underground shopping malls and the limited space of the fire extinguishing devices.
