Horizontal Water Bath Vaporizers with Venturi Mixer ModulesThese skid-mounted, packaged systems utilize a horizontal water bath vaporizer with a venturi type mixing system. Designed for capacities from 14MM BTU to over 250MM BTU per hour, the units are manufactured to meet or exceed requirements of the ASME Pressure Vessel Code and latest edition of NFPA Pamphlet #58. Intended for intermittent service, the units are approved for Factory Mutual (FM) or Industrial Risk Insurers (IRI) installations, and are also approved by Canadian Standards Association (CSA).

Standard design output pressure is 5 to 10 psig. Higher pressures of up to 50 psig are also available and require compressed air for operation. The vaporizer model number (WB) designates gallons per hour propane vaporization at 0 °F inlet temperature, and the mixer model number (HVS) designates millions of BTU per hour propane-air mixture. The model number of the vaporizer capacity requirement determines the type of vaporizer and all burner and safety features. Electrical requirements: AC 115 V 60 Hz, single phase, or 
AC 480 V 60 Hz, 3-phase (larger units).

All module units are designed for outdoor installation and require only nominal preventive maintenance. All units are manufactured to IRI specifications, and bear Factory Mutual (FM) and Canadian Standards Association (CSA) Approval.

For detailed technical specifications of the two main modules, horizontal water bath vaporizer and Hallberg venturi mixing system, please refer to the pages for these components:
