<p>The system is in two separate sections - a vaporiser (1) and a flow and pressure regulator (2) - connected by a simple tube (3). The vaporiser consists of a heat exchanger with a serpentine vaporising tube of a heat conducting material through which the gas passes, in liquid form at the inlet and and as a gas at the outlet, the tube being immersed in a heating fluid container in a sealed chamber made from an insulating material or equipped with an electric heating coil. The gas flow and pressure regulator has no thermal chamber, but incorporates a supple membrane controlling a valve on the gas inlet.</p> |
