The LPG Air Mixing Systems are basically used as stand-by system for replacement of Natural Gas or Peak Shaving for base load applications. Some of the Models have an integrated Vaporizers and LPG Air Mixing System. There are mainly two designs of LPG-Air Mixing System – ‘Vaporaire’ and ‘Blendaires’. ‘Vaporaire’ type of LPG Air Mixing System is a Venturi type of LPG Air Mixer which can be used for gas delivery pressure upto 15 Psig. max. The Equipment basically works on a Venturi design through which LPG vapours enter at a high pressure creating vacuum and thereby sucking in air from the atmosphere to give desired diluted gas. A solid state sequencer automatically Switches different arms of the unit taking command from pressure transducer. It is a very easy system to install and requires very little maintenance, if properly installed.
