<p>A compressed gas regulator apparatus 10 for controlling a pressurised OFN supply 28 has a regulator housing 20 with an inlet (24, fig 2), outlet (16, fig 2) and a flow path between. Inlet (24, fig 2) is releasably connectable to an outlet 26 of the OFN supply 28. An electrically operable regulator valve (30, fig 2) in the housing 20 for controlling a flow of gas along the flow path is provided, along with a pressure sensing device for sensing a backpressure at or from the gas outlet (16, fig 2). A regulator user interface 36 for inputting a backpressure value, a local regulator controller for automatically closing the valve when the user-selected backpressure is reached, a wireless regulator receiver in the housing 20 for remotely controlling the local regulator controller, and a discrete remote controller 18 having a remote user-interface 80 and a wireless transmitter for wirelessly transmitting a control signal to the wireless regulator receiver are also included. A second invention relates to a splitter device 14 used with the regulator, for connection to a suction line of an air conditioning system and a liquid gas outlet (16, fig 2) for connection to a liquid line of an air conditioning system.</p> |
