Vortex Pilot Gas Heater

The UVI Vortex Pilot Gas Heater (VPGH) is a heating device that prevents regulator pilot gas from freezing up in applications within natural gas transmission & distribution pressure regulation stations.

Universal Vortex Inc. Pilot Gas Heater (VPGP)

The VPGH protects pilot-operated regulators from freezing and where electronic instrumentation for monitoring is used. The Vortex Pilot Gas Heater is a Class I, Division 1 explosion-proof device that meets and exceeds federal and state requirements for regulator station design and applications. The heater was introduced in 2001 and has been used in various applications.

The VPGH is an alternative to pneumatic control heaters such as catalytic pilot gas heaters or electrical pilot gas heaters and offers energy savings and maintenance-free operation.
