HVS LPG-Vapor / Air Mixers with Water Bath Vaporizers

HSV Mixer VaporizerModel Numbers are WB-168/HVS-14 to WB-3000/HVS-250. The first part of the model number indicates the vaporizer capacity in gallons per hour; the second part indicates the mixer capacity in MMBTU per hour. All systems combine horizontal water bath vaporizers (08-series or 05-series) with Venturi-type mixing systems (HVS-series). They come complete with vaporizer, venturi mixer, surge tank, interconnecting piping, electrical and safety controls, and are mounted on a common steel skid. This design concept makes them very compact, easy to install and to maintain, and very reliable.

All systems are factory-tested prior to shipping. After placing a system on a non-combustible surface (i.e. concrete pad), filling the vaporizer with heat transfer solution, and connecting it to electrical supply, liquid gas supply, and mixed gas outlet, it is immediately ready to produce high-quality gas which is directly compatible and interchangeable with NatGas. Standard design output pressure is 5 to 8 psi, or 9 to 12 psi (please specify desired output pressure with order). Higher pressures up to 40 psi are also available and require compressed air for operation. In system with High Pressure Option, the surge tank is ASME U-stamped .

All WB/HVS systems monitor the gas pressure in the surge tank, using a pressure transmitter that is connected to a Siemens or Allen-Bradley PLC. The PLC, which is shared with the vaporizer, “sequences†the venturi lines and controls all mixer safety functions. The PLC also communicates with a color LCD display with Touch Screen Operator Interface, displaying system pressures, and any trouble conditions that may occur. The WB/HVS series is designed for outdoor installation and requires only nominal preventive maintenance. Intended for intermittent service (see Note), the systems are manufactured to meet or exceed requirements of the ASME Pressure Vessel Code Section VIII, and the latest edition of NFPA Pamphlet #58. They are approved by Factory Mutual (FM) and Canadian Standards Association (CSA), and are suitable for Industrial Risk Insurers (IRI) installations.

All systems are factory tested, primed, painted and ready for installation. They come with 2 sets of operating manuals and test reports. All vaporizers are equipped with “smart†Liquid Carryover Protection.

All HVS Mixers are equipped with two solenoid valves per venturi train. The “dynamic†solenoid valve opens and closes each time a venturi train is activated to produce mixed gas. The “static†solenoid valves opens when the mixer is started and stays open until the mixer is stopped, or until a high-pressure alarm occurs. This feature provides an additional level of safety, and prevents the unwanted discharge of mixed gas in case of a failure of the “dynamic†solenoid valve.

The mixer sendout pressure and the sequencing of the venturi lines (differential pressure between trains; ON‑OFF deadband) can be adjusted through simple inputs at the touch screen. A separate “Venturi Cycle Counter†for each venturi train increments each time a venturi train is activated. This information can be used to determine when the mechanical components of a venturi train should be closely inspected, overhauled, or replaced.

The required vapor supply pressure depends on the desired sendout pressure, on the type of available LPG (Propane/Butane content), and on other factors (i.e. altitude). Typical supply pressures for “Propane†and 5-8 psi sendout pressure are 50-70 psi. Mixed Gas Sendout Pressures of more than 8(9) psi require the High Pressure option, which includes a surge tank with ASME “Uâ€-Stamp.

Please Note:   Venturi-based LP/Air mixers are generally considered “for intermittent useâ€. Due to the relatively limited useful life of their dynamically exercised mechanical components (regulators, check valves, solenoid valves, air intake valves, etc. are typically specified by their respective manufacturers to withstand 200000 to 500000 cycles), they are not very well suited for baseload applications. Their main application is “Emergency Backupâ€.
