XPV Packaged Propane-Air Mixing System

XPV systems are self contained units that provide a natural gas compatible mixture of propane and air or LPG vapor and air. These systems are supplied with a dry electric vaporizer and a venturi mixer. An accumulator tank enables the venturi to cycle on and off to meet the required load allowing 100% turndown. Operation is quiet, reliable and safe.

XPV compact LPG-air mixing systems are available in various propane and LPG models providing gas/air mixtures from 2.5 – 28 million BTU/Hr at pressures from 5-12 PSIG atmospherically. A liquid pump, such as the Algas-SDI STABILAIRE liquid LPG pump may be required to provide sufficient gas pressure for the mixing process.

XPV Packaged Propane Air Mixing System

Compact unit incorporates XP electric vaporizer, venturi mixer, and surge tank for ease of installation and operation.


Explosion-Proof design allows the unit to be placed directly adjacent to the propane supply tank.


System provides 100% turndown capability and is available in mixed gas delivery pressures of 5, 8, and 12 PSIG.


Venturi silencer promotes quiet operation.


Perfect for confined space applications and those requiring additional security – schools, bakeries, general industry – these systems are explosion proof and take up very little space.


Ready to operate in 1 minute from a cold start.


Systems up to 12 psig discharge pressure do not require compressed air.


Can be used with LPG — discharge pressures vary. Contact factory for more information.


ASME constructed surge tank with “U” stamp.


FM Approved.


Available in most voltage configurations.
