About VST
Vapor Systems Technologies, Inc. began in 1990 with
the vision of
One Company
–
One Integrated Solution
.
Today, that philosophy is still in place and getting
stronger. Recognizing that a healthier environment is a
need and not an option, VST has dedicated its
undivided attention to the ever-changing, stringent
regulations that govern fugitive vapors at gasoline
dispensing facilities (GDF). To this challenge, VST is
committed to a continual R&D campaign of developing
the most current, technologically advanced solutions to
service not only the United States, but also the world.
VST specializes in the development, engineering, and manufacturing of products that are sold into the
GDF segment of the petroleum industry. The VST focus provides our customers and users with
exceptional products, services, and innovative solutions for improving the fueling-station experience as
well as the world’s air quality.
VST’s product offering includes curb pump and vapor recovery hoses, safety br
eakaways, nozzles, and
emission-control system - GREEN MACHINE. The ENVIRO-
LOC™ vapor
-recovery product offering
represents the most innovative concept in the industry for trapping fugitive vapors from the front end
(vehicle refueling) to the back end (vent risers) of the GDF site.

GREEN MACHINE Theory of Operations
•
The VST GREEN MACHINE operates based on monitoring the Underground Storage Tank
(UST) system pressure.
•
The GREEN MACHINE controller provides UST pressure data via a Pressure Sensor, located
in the GREEN MACHINE, and manages the GREEN MACHINE operation.
•
The pressure data is provided to the VST Control Panel for system monitoring functions.
•
The closed loop vapor piping solution continuously operates the system to control UST
pressure below 0.2 IWC.
•
See Figure 11-1
for an overview layout of where a GREEN MACHINE is located and
operates in a gasoline station.
