b. Stage 2: LG-X 4000 Fuel Conditioner – to reduce the size and mass of fuel sediments
which naturally form in fuel, and to eliminate microbial contamination thus eliminating the
need for toxic biocides
c. Stage 3: Primary Filtration 10 micron Fine Filter as standard, with water sight-glass and
water drain valve – Cartridges shall be available in 1, 5, 10, and 25 micron ratings
d. Stage 4: Secondary Filtration 10 micron Coalescing Filter as standard, with water sensor
probe and water drain valve – Cartridges shall be available in 1, 5, 10, and 25 micron
ratings in each of three cartridge types: Fine Filter, dissolved and emulsified water
absorbing “WB water block”, and Coalescing
e. Primary and secondary filters shall be equipped with a liquid-filled pressure gauge and
differential pressure indicator
5. Water Sensor: Watect model 550 microcontroller-based water sensor alarm module to
eliminate probe corrosion.
6. Controls / Display functions : System control features, indicator lights and emergency
stop button shall be located on a descriptive external control panel on the front door of the
enclosure for easy operator access. Additional alarm and system status information shall be
displayed inside the system on a full color programmable touch-screen PLC controller,
displayed on a dedicated webpage that monitors the system as well as delivered through E-
mail and SMS messages to designated individuals. System shall provide following control
and display function:

g. Pump running indicator, amber indicator, external display
h. High vacuum, high pressure, no flow, high water alarm and leak detection, red
indicator, external display
i. Emergency stop push button, red, latching - turn reset, external access
7. Electrical enclosure / Controller : All electrical control features shall be contained within a
separate UL 508A listed industrial control panel located within the mechanical enclosure.
The controller shall monitor the following system alarm points:
a. Leak in enclosure detection (system shutdown)
b. Primary filter high vacuum sensor (system shutdown)
c. Primary filter high water sensor (system shutdown)
d. Secondary filter high pressure sensor (system shutdown)
e. Flow switch (system shutdown after priming delay)
f. External system shut down input
g. Motor Overload (system shutdown)
8. Pump: Positive displacement, internal gear, direct coupled, rotary pump with cast iron housing
and built-in pressure relief bypass valve. Pump flow rate of 30 gallons per minute.
