ABSTRACT:
A Method for Supplying Industrial Gases Using Integrated Bottle Controllers that overcomes the problems encountered by previous gas cabinet equipment is disclosed. The present invention comprises a compact and virtually explosion-proof controller (10) that is anchored securely to the top of a standard gas bottle (12). The entire system resides within a housing (11) that sits atop a conventional gas bottle (12) that would normally be enclosed within a gas cabinet (25) that may be sixty times the volume of the present invention. The controller (10) includes a housing (11) that has a top or lid (14), an upper cylinder (16), an annular wall (18) which forms a seal with the bottle (12). In a preferred embodiment of the invention, filled and cleaned bottles are connected to controllers at a fabrication clean area. The controllers are then operated remotely using a radio frequency or infra-red control. After the bottles are depleted, the controllers are removed and tested. The bottles are then refilled for reuse.
