Horizontal Water Bath Vaporizers

AES manufactures two lines of Water Bath Vaporizers: the 08-Series for capacities from 168 gph to 508 gph (322 kg/h to 975 kg/h), and the 05-Series for capacities from 455 gph to 10,005 gph (873 kg/h to 20 metric tons per hour).

All AES water bath vaporizers are of "horizontal" design. Top, sides, and rear are insulated to hold the temperature of the water bath. The vaporizing tube bundle and all LPG piping conform to the standards of the ASME Boiler and Pressure Vessel Code and the latest edition of NFPA Pamphlet #58. The design is approved by Factory Mutual (FM) and Canadian Standards Association (CSA), and is accepted for Industrial Risk Insurers (IRI) installations. The vaporizers are also available with European CE Approval (third-party inspection by TÜV Rheinland).

A mixture of water and antifreeze is the heat transfer medium. A pump constantly circulates the solution to reduce heat stratification. The vaporizers are skid mounted, factory tested, primed, painted and ready for installation. They are ready for connection to properly sized electrical supply, liquid LPG inlet, and vapor outlet.

The vaporizers come with 2 sets of Operating Manuals and Test Reports (one physical; one digital), are designed for outdoor installation, and require only nominal preventive maintenance. The model number (WB-XXXX) designates the vaporization capacity in gallons per hour Propane vaporization at 0°F (-18°C) inlet temperature.

All WB vaporizers are manufactured with a protective enclosure for the burner and the control components. Models WB-1805 and above come standard with an extended control room (maintenance house), which is available as an option for the smaller models WB-455 to WB-1505.

Model numbers ending in "8" utilize a European-style compact power burner; model numbers ending in "5" utilize Maxon Tube-O-Therm burners (or similar types). Both series are equipped with an Agency-approved Safety Controller or Safety PLC, and electronic flame safe guard. 

Both series of vaporizers are equipped with "Smart" Liquid Carryover Protection function, using a Rosemount pressure transmitters and a Rosemount temperature transmitter in the vapor outlet.

Prices for all models include a control panel with Siemens S7-1200 or Allen-Bradley MicroLogix-1400 PLC and a high-resolution color LCD display with Touchscreen Operator Interface for system status display and first-outage indication (Alarm History). Ethernet Interface is standard on all PLCs. All standard control systems are equipped with a built-in VNC Server for remote monitoring and control. An open (unlimited) license of the VNC viewer software is included and can be installed on multiple PCs or Laptops.
