Commissioning/Initial Start-Up
Preparations
Before operating the MTC, we recommend determining the amount of contaminants, free water, and sludge in the tank.
AXI International provides a variety of tank sampling equipment, including Sampling Pumps, tubing and bottles, as well as
Tank Samplers (“Bacon Bomb”) – please see our FS Fluid Sampling line of products. Please make sure the samples are
taken from the bottom of the tank (in the deepest spot). Use a stick with “Kolor Kut” paste on the end, reach through the top
of the tank, and place the end of the stick all the way at the bottom of the tank. Kolor Kut paste will show the water level in
the tank, and indicate how much water, and sludge, will have to be removed. Call AXI International for further information
on other fuel sampling equipment.
Note: Some biocides render water nding pastes inert.
Mobile Tank Cleaning System Overview
The MTC-X is a two-stage mobile fuel conditioning and tank cleaning system. It efciently removes sludge and water from
fuel and oil tanks, restoring and optimizing fuel quality in the same operation.
The system is designed as a “fuel/oil dialysis system” that circulates and cleans fuel/oil by pumping it from the tank, processing
it through the MTC-X, and returning it back to the tank. The system can also be used to clean fuel or oil by pumping it from
one tank, through the MTC-X, into another tank and/or suitable container.
The MTC-X System processes fuel, or oil, by pumping it from the tank, through the clear intake hose attached to Port 1,
through the main bag lter, down to the diverter valve and out Port 2. The discharge hose is connected to port 2.
The MTC-X System has two modes: Bypass Mode and Fine Filtration Mode.
Bypass Mode sends the fuel through the bag
lter only, then back to the tank, bypassing the
ne spin-on lters. Fine Filtration Mode sends
the fuel through the water block and/or ne
lter(s) and then back to the tank. The diverter
valve is used to change the operational mode.
Ports 1 and 2 are equipped with Quick
Disconnect Couplings that easily connect
to the matching couplings on suction and
discharge hoses.

General Tank Cleaning Procedure
The MTC-X has two different operating modes, providing the operator exibility and time efciency.
In Bypass Mode, bulk water and sludge are removed from the tank into a separate container for disposal. The fuel bypasses
the ne lters, removing free water, sludge, and particulate, as small as 1 micron, from the tank. During this step, the system
is not in a re-circulating mode. The fuel enters through Port 1 and exits through Port 2 into a separate waste container. Water
and sludge are directly removed from the tank and collected in an appropriate container for disposal. Next step, while still in
bypass mode, put the hose that was in a separate container back into the main tank to create a kidney loop. This process
will further save and extend the life of the spin-on lters, and remove the worst of contaminants, before polishing with ne
lters to meet the required cleanliness.
In Fine Filtration Mode, the MTC-X system is continuously restoring, reconditioning, and returning the fuel back to the tank.
Fine Filtration mode will continuously remove free water and particles as small as 1 micron, utilizing high efciency spin-on
lters.
We always recommend keeping a “before” and “after” bottom tank sample for “show & tell” purposes to demonstrate the
improvement of fuel color, clarity, and opacity.
AFC Fuel Additive
The use of AXI International AFC-705/710 Fuel Additive is an essential part of any tank cleaning and fuel polishing procedure,
as AFC can more rapidly and efciently decontaminate and clean the entire fuel system.
The additive is best introduced into the process after Fine Filtration Mode. Before dosing the tank with AFC-705/710,
remove as much of the sludge and free water as possible.
Adding AFC-705/710 to the tank will speed up the cleaning process by breaking down and dissolving the sludge covering
the tank walls and bottom. AFC-705/710 will decontaminate areas and sections of the tank that are out of reach of the
suction hose.
It is recommended to use a higher concentration of one to twenty ve hundred (1:2500) instead of one to ve thousand
(1:5000) for the rst treatment. This has proven to be very helpful in accelerating the rate of dissolving sludge. Higher doses
may be necessary, depending on contamination level of the fuel.
AFC-705/710 is a full spectrum fuel additive, containing a combustion catalyst, surfactant (705), detergent, dispersant,
corrosion inhibitor, lubricity enhancers, and a fuel stabilizer that eliminates the need for expensive, toxic biocides.

After Fuel Polishing Process
1. Stabalize the Fuel
AFC-705/710 will stabilize the fuel in tanks used for long-term fuel storage. When a recirculation or STS Automatic
Filtration System is not in place, AFC-705/710 will maintain fuel quality and prevent formation of sludge for up to 12
months. Added after the fuel polishing process, it is not necessary to add more AFC-705/710 until additional fuel
is added into the tank, or an environmental condition for the fuel has been altered (introduction of water or other
contamination.)
2. Prevent Water from Accumulating
The use of AXI Water Eliminators, or tank breathers, will prevent water from accumulating in the tank. The water
eliminators will absorb and remove any water from condensation or other sources. Preventing water accumulation
eliminates microbial growth and the need for toxic biocides.
3. Monitor Fuel Quality
Liquid-Cult Fuel Test Kits are ideal for monitoring your fuel supply for microbial contamination. The tests provide
indication of bacterial and fungal activity.
4. Tank Cleaning Systems
AXI International Tank Cleaning Systems signicantly lower operating costs, save fuel, and eliminates the build up
of solids, sludge, and acids. AXI International Technology enhances personnel safety and addresses environmental
concerns by preventing the need for costly toxic biocides. Larger capacity mobile and stationary tank cleaning systems
are available.

Filter Congurations
The AXI dual in-line ltration setup allows for various modes of operation. The lters can be arranged to clean particulate, or
both water and particulate, out of the ow stream of uid. A single lter element can also be used for refreshing a relatively
clean system. The following information will show you the various congurations.
Filter #1 Filter #2
Fine Filtration Mode can be engaged during operation by changing the position of the diverter valve to position 2. This will
divert the ow of fuel through the spin-on ltration plumbing. The fuel will enter lter #1 rst (void lter if only using single lter)
and then ow through lter #2. When the system is in Fine Filtration Mode utilizing two (2) lters, it is important to install
the lters in the correct order. The higher micron rated lter should be installed as lter #1, and the lower micron rated lter
should be installed as lter #2. This process removes larger particulate, then ne particulate (or water), as shown in Figures
1.2, 1.3, and 1.4. Recommended congurations for lter positions are shown below in Table 1.1.

System Operation
Operational Modes
The MTC-X system has two modes of operation: Bypass Mode and Fine Filtration Mode (Figure 2.1).
Bypass Mode:
Bypass Mode is an important step in the fuel polishing process. This will remove any large contaminants and any additional
free water from the fuel. This process should be performed until the majority of large contaminants are removed. In Bypass
Mode, the fuel enters the MTC-X inlet hose and moves through the pre-lter (bag lter). After leaving the pump, the fuel
encounters the diverter ball valve. For Bypass Mode, the diverter ball valve should be in position 1. This allows the fuel to
bypass the ne ltration plumbing and continue out the MTC-X outlet hose (path shown by blue arrows in Figure 2.1).
Fine Filtration Mode:
After pre-ltration, Fine Filtration Mode is typically the last procedure in the fuel polishing process to bring fuel cleanliness to
an acceptable level. This mode of ltration will continue to use the pre-lter (bag lter), but will direct the fuel through the ne
ltration spin-on lter(s). In this mode, the user has the option to use a single spin-on lter and void a lter, or two spin-on
lters in series (see Figure 2.1). Filter congurations are shown in the “Filter Congurations” section.
Note: Never restrict the ow on the suction side of an MTC; e.g. by using a smaller ID hose or pipe or attaching the suction
hose to a tting on the tank that has a smaller ID than the hose. This will lead to excessive pump load, noise, and will
ultimately damage the pump.
Operating Procedure
Phase 1:
AXI recommends Three phases to successfully polish a fuel tank. This will ensure all water is removed from the fuel,
particulate is removed, and the fuel is in an optimal condition. The goal of the rst phase is to remove any free water and
sludge on the bottom of the tank without mixing the water into an emulsied state within the fuel.

Phase 2:
The goal of the second phase is to remove any additional free water within the tank and also remove any large contaminants
and sludge. This phase will clean the fuel and should be a precursor to using the more expensive spin-on lters. It should
be noted that meeting required cleanliness codes is typically not possible with pre-ltering alone. Phase 2 is used to extend
the life of the spin-on lters, and remove the worst of the contaminants, before polishing with ne lters to meet the required
cleanliness.
1. Keep the diverter valve in Bypass Mode (position #1).
2. Place the return line in the tank at the farthest point of the tank from the suction hose (secure discharge hose) (Figure
3.1).
Note: Never restrict the ow on the suction side of an MTC-X; e.g. by using a smaller ID hose or pipe or attaching the suction
hose to a tting on the tank that has a smaller ID than the hose. This will lead to excessive pump load, noise, and ultimately
damage the pump.
3. Ensure a pre-lter bag is equipped in the pre-lter vessel (Figure 3.2).

4. Open the inlet ball valve and start the system.

Phase 3:
This phase is the most important phase in meeting specic cleanliness codes. Unlike the pre-lter bags, the spin-on lters
typically use absolute rated media. Absolute lters have a very high efciency and will ensure that fuel leaving the system is
clean to specication and has a low water content. Like previously mentioned, pre-ltering should be performed to remove
any large particulate, water, and sludge. Pre-ltering will extend the life of the spin-on lters. The system is equipped with
two (2) spin-on lter heads. These can be used in different congurations to ensure the fuel is as clean and dry as possible
(see “Filter Congurations” section).
1. The MTC-X is designed with a single discharge port so that the system can be switched from Bypass Mode into Fine
Filtration Mode during system operation. Before changing over to Fine Filtration Mode, ensure that spin-on lters are
tightly sealed on to BOTH lter heads (one spin-on may be a void lter, see “Filter Congurations” section). Ensure
that the accessory selector valve is in the OFF position. Change the diverter valve from Bypass Mode (Position #1) to
Fine Filtration Mode (Position #2). The system is now diverting ow through the two in series spin-on lters and out
the discharge port (Port #2).
2. During Fine Filtration Mode monitor the pre-lter vacuum gauges, the water sight glass on the prelter, and the two
differential gauges. The differential gauges will provide an indication of how clogged the spin-on lters are, and when
they should be serviced. A gauge in the red provides an indication that the lter should be serviced (Figure 4.1).
3. When a spin-on lter is clogged, check the water sight glass to ensure the pre-lter contains no water. Shut the system
down, close the inlet ball valve, and drain the water if it is visible.
4. Open the inlet ball valve, turn the system on and follow the procedures of “Filter Drain” section to perform the lter
draining.
5. When ready to inject AFC into the tank, follow the procedure in “Additive Injection” section.
Figure 4.1- Pre-lter vacuum gauges, and differential gauges
Run several volume cycles of the entire tank, continuously reducing the micron rating of the bag pre-lters. This will
remove the majority of large contaminants from your fuel. Keep an eye on the vacuum gauges on the pre-lter vessel.
The bottom vacuum gauge will display when the pre-lter bag must be serviced. The top gauge will give an indication
to the static head the system is currently experiencing, while the bottom gauge will provide an indication to the vacuum
the pump is experiencing. Also, watch the water level display sight. When water is observed in this sight, it is time to
drain the water. Shut the system down (close inlet ball valve) and drain the water until fuel is observed in the clear
drain hose.

Priming the System
Note: The MTC System is equipped with a positive displacement vane pump. It should never be run dry and started without
the hoses attached and/or valves in the closed position. Failure to do so may damage the bypass valve and/or pump.
Priming Procedure
Before turning on the pump make sure the entire suction side of the MTC system (suction hose, separator, plumbing, pump,
strainer, etc …) is primed and lled with oil/diesel fuel. Running the pump dry could cause pump damage and pump to not
operate properly.
Note: The separator/coalescer has to be full at all time to perform properly.
! IMPORTANT ! Never exceed 15” HG on vacuum gauge located before of pump.

Maintenance
! IMPORTANT ! It is recommended that only qualied, experienced personnel, familiar with this equipment,
who have read and understood all the instructions in this manual should install, operate, and maintain the
system.
! IMPORTANT ! Always disconnect the system from the electric power supply before working or servicing
it. Do not proceed with any maintenance unless the pressure or vacuum has been released, the system has
been allowed to reach ambient temperature, and all uids have been drained.
Draining and Storing the System
1. Before releasing the quick disconnect couplings, allow all fuel to ow out of the hoses by draining the system, or take
the suction hose out of the tank while the pump is still running and wait till system is purged and empty.
2. Place an appropriate container under each drain valve. Open both the valve on the separator and the valve under the
pump. Use the air purge valve on top of the separator to make sure all of the uid can be drained from the system.
Opening the valves and the air purge valve will allow fuel to ow down and out of both hoses into the tank.
Pump
Check pump for leaks, worn vanes, and if bypass valve operates correctly. We highly recommend carrying a spare pump.
The MTC pump can be easily changed in a matter of minutes by opening the unions and/or short hose connections. Spare
part kits are also available for all MTC pumps. Keep the pump lubricated and pour some oil into pump head for storage.
LG-X Fuel Conditioner
Particles and rust can collect inside the LG-X unit, and over time cause a ow restriction and/or diminish its effectiveness.
Open the lid of the LG-X Fuel Conditioner by unscrewing the lid screws and clean the magnet and fuel chamber. Inspect
o-rings prior to reassembly.
Suction and Discharge Hoses
We recommend replacing the suction hose every year and the discharge hose every two years. Heavy use, visual
deterioration, damage, or poor condition and excessive wear can require an even earlier change.

Flow Rate
Flow rate through a pump is dependent on the amount of restriction put on the pump (both suction side restriction and
pressure side restriction). Pump curves allow a customer/user to understand the ow rate they will experience for a given
restriction on the system.
For the MTC-X, the restriction can come in the following forms:
Suction Side of Pump:
• Clog in line
• Smaller hose than recommended by manufacturer
• Clogged pre-lter
• Partially closed ball valve
On the suction side of the pump, the bottom vacuum gauge will show the total vacuum the pump is experiencing, shown in
inches of Mercury (inHG, or “HG), which is a common way to show vacuum within the industry. When converting inches of
Mercury (inHG) to Pounds per Square Inch (PSI), divide the inches of Mercury by 2 (i.e. 12inHG = 6psi).
Pressure Side of Pump
• Clog in line
• Smaller hose than recommended
• Some types of ow meters
• Clogged spin-on lters (two lters in series added together)
• Partially closed ball valve
To understand the total restriction on the pump, the suction side restrictions should be added to the pressure side restrictions.
This restriction value (in psi) can be used with the pump curve to nd the approximate ow rate the system should experience.
See (Figure 5.1) to calculate the approximate ow of the system for a given restriction.
Note: Low ow rate can often be xed by using a void (bypass) lter in place of lter #1. This provides very little, if any,
restriction on the system, but removes a stage of ltration.
