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 10005 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, 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 are equipped 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 TOT burners (or similar types). Both series are
equipped with an Agency-approved Safety Controller, GasLeak Monitor with
long-life infrared sensor, and electronic flame safe guard. This
combination elevates the safety of the vaporizers to "Performance Level
4" (formerly known as SIL 3).
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-1100 (or MicroLogix-1400) PLC and a high-resolution color LCD
display with Touch Screen Operator Interface for system status display
and first-outage indication. Ethernet Interface is standard on all PLCs.
The Siemens PLCs are also available with Profibus DP interface. 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
description can be found in AES brochure “Water Bath LPG Vaporizers”.
Standard lead time on
all models WB-555 to WB-4505 is 6 weeks. Larger models (WB-5505 and
above) are typically available within 90 days. Some models are carried
in inventory (mainly 08-Series up to 508 gph / 975 kg/h). Actual lead
times depend on factory workload and may vary.
