AS Direct Fired LPG Vaporizer

AS Direct Fired LPG VaporizerThis vaporizer line has been phased out. Information is provided for reference purposes.

Direct Fired LPG Vaporizers do not require an electrical source for their operation. They are manufactured in capacities of 50, 80, 120, 160, 240, 360 and 480 gallons per hour propane vaporization at 0 °F inlet temperature. Featuring a unique primary and secondary air burnerthat assures quick ignition, there are no openings or louvers at the base of the unit which could cause pilot outage problems. The units are manufactured with a brass liquid inlet valve, dual liquid level control to prevent liquid carryover, and a stainless steel ball float with 600 psi pressure rating. Encased in a durable, powder coated steel sheet metal cabinet, the door is easily removed for simple access and maintenance to burner assembly and temperature control valve.

The vaporizing tube and all propane piping conform to the standards of Section VIII, Division I of the ASME Boiler & Pressure Vessel Code, NFPA #58, and are approved for Factory Mutual (FM) and Industrial Risk Insurers (IRI) installations. The Model Numbers (AS-xxx) designate gallons per hour propane vaporization at 0°F inlet temperature.

AS direct fired LPG vaporizers include the following features:

  • Meet industry specifications outlined in ASME Boiler & Pressure Code, Section VIII, Division I, and NFPA #58. ASME “U” Stamp.
  • Two-stage burner regulator for stable burner pressure.
  • Factory Mutual (FM) approved.
  • The vaporizer heat exchangers carry ASME ‘U’-Stamp.

AS models offer several options for specific needs:

  • Liquid inlet hand valve.
  • Electric automatic re-ignition for AC 110 Volt or DC 9 Volt.
  • Liquid inlet strainer (standard AS-160 – 480 models).
  • Vapor Outlet shutoff valve (standard AS-160 – 480).
