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 steam 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
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
(Allen-Bradley MicroLogix), which is connected to a 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.
Standard lead time on all models is 6 weeks. Actual lead times depend on
factory workload and may vary.
