VORTEX PILOT GAS HEATER (VPGH)

The Vortex Pilot Gas Heater (VPGH) is an emissions free, energy saving, and maintenance free alternative to catalytic pilot gas heaters, and electric pilot gas heaters. The VPGH protects pilot operated regulators from freeze off at gas pressure regulation stations and has applications at CNG and LNG stations. The Vortex Pilot Gas heater is Class 1, Division 1 explosion proof device that meets and/or exceeds all federal and state requirements for regulator station design and applications. Since introduction in 2001 the VPGH has been applied in all types of natural gas applications: farm taps, district regulator stations, town border stations, power plant combustion turbine fuel gas, ethanol production plant fuel gas delivery, CNG stations, and LNG stations.

Vortex Pilot Gas Heater Features:

  • Adds up to 90°F to the pilot supply gas

  • Heats pilot gas as an outcome of routine gas pressure reduction in the vortex tube

  • Not sensitive to wet feed gas

  • No lost gas.

  • No moving parts.

  • No chance of overheating.

  • No maintenance, EVER.

  • Easy to install or retrofit in new or existing facilities.

  • Working pressure is 1500 psig or 100 bar.

  • Available in 2 designs that can work with any currently available pilot gas pressure regulators (PR).

  • Single Path (VPGH-SP) has a single heating chamber to serve one pilot at a time.

  • Dual Path (VPGH-DP) can simultaneously serve two pilots.
