[Xingtai] largest manufacturer HL-type gas bus, the bus also known concentration of gas converging device, the main bus with oxygen, nitrogen, bus, bus argon, carbon dioxide, bus, etc., palace Chen Xu specializes in the supply, Phone 18733907082 centralized gas supply apparatus is widely used in large-scale use bus centralized gas supply factories, mines, hospitals and research institutions, and other units. It is about more than just the cylinder into two groups, each bottle of gas will bring together, through pressure, through pipes to each point of the supply of equipment to use. When working with a group of first gas bottle, gas bottle when the group spent on automatically switch to another set of gas bottles, while audible alarm signal so that staff promptly replaced the bottles when another When a group of exhausted gas bottle, and automatically switch back to its previous state. Such cyclical, in order to achieve the purpose of stable gas supply uninterrupted, if during power outages can also manually switch supply. Automatic switching bus known as automatic switching gas centralized supply device, which is widely used in large-scale use of gas units in factories, mines, hospitals and research institutions and other. Automatic switching centralized supply device is more than just about the cylinder into two groups, each bottle of gas will bring together, through pressure, through pipeline gas supply of equipment to each point of use. In operation, it is the first to use a set of bottles of gas, when the gas bottle runs out group will automatically switch to the other group of state gas bottle, while audible and visual alarm signal to staff in time for duty Under bottles; bottle when another group of gases exhausted, and automatically switch back to its previous state. Such cyclical, we can achieve the purpose of stable gas supply without interruption, if power supply can be switched manually Shihai achieve.
