Vertical Circulating-Hot-Water Bath Vaporizers
 
Alternate Energy Systems offers a complete line of circulating hot water vaporizers in capacities from 200 gallons per hour to 3000 gallons per hour. The vaporization tube is of multi-pass design to transfer the maximum heat to the liquid. The tube bundle and all propane piping conform to Section VIII, Division I of the latest edition of the ASME Boiler and Pressure Vessel Code. The pressure vessel carries the ASME ”U” stamp and is National Board registered.

The prices shown below include dual liquid carryover protection through an ultrasonic liquid level transmitter in the pressure vessel, and “smart” liquid carryover protection with Rosemount pressure transmitter and temperature transmitter in the vapor outlet; and liquid inlet valve (solenoid valve). Temperature gauges in water inlet and outlet, and in pressure vessel shell and vapor outlet are standard.

Vaporizer design, wiring, controls, and electrical components and their installation comply with the latest editions of NFPA #58 and NFPA #70.

All safety devices of the vaporizer, including the dual liquid carryover protection, are monitored by a programmable logic controller (Siemens S7-1200 or Allen-Bradley MicroLogix-1100), which is connected to a high-resolution color LCD display with Touch Screen Operator Interface. The operator interface provides start/stop control for the vaporizer; it displays the system status, and any failure conditions that may occur, in plain English (with date/time stamp). The electrical enclosure for the PLC and the operator interface are to be installed in a remote, non-classified location. A small explosion-proof enclosure, mounted to the vaporizer, provides local start/stop and alarm reset functions.

Ethernet Interface is standard on all PLCs. The Siemens PLCs are also available with Profibus DP interface. All vaporizers are configured for remote monitoring and control via a built-in VNC server. The VNC viewer software is included.

Standard lead time on all models is 6 weeks. Actual lead times depend on factory workload and may vary.

Water Flow Requirements are based on 185°F (85°C) water temperature and 40°F (22°C) inlet/outlet temperature drop.
Weights and dimensions are approximate. Dimensions are for heat exchanger shell only.
Trim and accessories are not included in dimensions.
Specifications are subject to change without notice. Call factory or distributor for price quotation and actual lead times.
