Principal of Operation
The ThermoJet Oil Purifier works on the principal of air stripping. The use of air or nitrogen
bubbled through contaminated liquids has long been used to remove contaminants. But the
use of this technique was restricted because the volume of gas required was large due to
limited mixing of the gas with the liquid. The unique technology embodied by the ThermoJet
makes air/gas stripping practical and efficient because of the mixing and intimate contact of
the air/gas with the fluid being cleaned. In addition, the ThermoJet utilizes the principal that
the capacity of a gas to entrain moisture increases exponentially with temperature.
The ThermoJet is designed to operate on ISO 32 through ISO 220 oils from circulating oil
systems. Oil with higher viscosity (ISO 150 and ISO 220) must be at 40oC (100oF) minimum
temperature at the inlet to the ThermoJet during start-up.
Degasification
The ThermoJet® removes dissolved light hydrocarbon gases such as propane and H2S from
industrial lubricants. In refineries and petrochemical plants an ideal application for the
ThermoJet is the removal of hydrogen sulfide from compressor seal oil. The ThermoJet
returns
the viscosity of the lube oil and restores the oil flash point to like new levels. No longer is there
a need to dispose of gas laden and sour lube oils; these oils can be purified and reused.
Flow through the Unit
The suction pump of the ThermoJet draws contaminated oil from the user lube, seal or
hydraulic system. Flexible hose or hard piping can be used to connect the ThermoJet to the
system reservoir. A one and one half horsepower motor drives the suction pump. The suction
pump is protected by a “Y” strainer. From the pump the oil passes through a filter. This
cartridge filter can be easily replaced. It is recommended replacement be made when the
pressure differential across it, as monitored by two easily read gages which are externally
mounted on the panel above the access door, reaches 2 BAR ( 30 PSI). From the filter the
oil passes through the heater that elevates the oil to 82° C (180° F).
The electric heater temperature is set and controlled with a solid-state device whose
operation is viewed through a window on the electrical control box. After the heater, the oil
passes through the heart of the ThermoJet
which is the dual stage jet mixer
The Jet Mixer
This proprietary and uniquely designed device is the heart of the system. Without the aid of
secondary pressure, it continuously and automatically draws ambient air or inert gas such as
nitrogen into the heated oil stream as delivered to it by the inlet pump. The ambient air/gas
becomes intimately mixed with the oil and assumes the temperature of the oil. The oil leaves the
Jet Mixer and is directed to the separation vessel that operates at atmospheric pressure. Here
the moisture laden air, or gas saturated nitrogen, expands and leaves the oil thus cleansing
the oil of water or dissolved hydrocarbon gases.
Return of Clean Oil
In the separation vessel the oil from the jet mixer cascades down trays to promote the release
of the saturated air/gas. A volume of oil is maintained in the lower portion of the separation
vessel to allow any entrained air to leave the oil so that none is contained in the return oil
stream. The second close coupled pump driven by the electric motor returns oil to the user
reservoir. Water vapor vents from the separation vessel and travels through a filter and oil
absorbing media to insure that discharge from the unit is oil free. The water condensate
discharged from the ThermoJet can be piped to a sanitary sewer.
MountingOptions
The ThermoJet Model G3700 Oil Purifier is offered in two different mounting configurations so that
the unit can best fit client requirements. All series units are available as base mounted with lifting
eyes. The H-2000 series is also available mounted on a fork lift able base.

Receipt Inspection
Remove all shipping materials and plastic plugs.
Inspect for shipping damage externally and internally (open enclosure door), and report any found
to the manufacturer immediately. It is desirable to take photographs of any damage to
substantiate your claim.
Inspect for completeness of materials and equipment against the packing list and the purchase
order.
Placement of Equipment
After verifying the adequacy and strength of all relevant support surfaces, place the ThermoJet
Oil Purifier as close as possible to the oil reservoir in an upright position. See Dimensional
Drawings in the PARTS LIST / DRAWINGS / SCHEMATICS section of this manual for anchor
bolt and equipment clearance dimensions
The ThermoJet Oil Purifier is constructed with lift rings. Ensure that lifting equipment and rigging
is suitable for safely lifting, moving and placing the equipment.
Using standard plant practices secure the ThermoJet Oil Purifier to the installation surface by
bolting the four (4) mounting feet.
NOTICE:
Be sure to leave working space around the system and consider
space requirements for electric heater removal, fully opened access
door, control panel enclosure door, and gauge monitoring.
Do not tip or stand equipment on edge
WARNING
Use suitable transport equipment for lifting and
setting the equipment into place. Ensure that the
equipment is secured prior to and during lifting
and transport. Stand clear of the all equipment
while being maneuvered. Crane and fork truck
operators should be properly trained in there
operation.

Inlet and Return Oil Piping Connections
The oil inlet and outlet connection sizes are 1” FNPT. The user suction and discharge line sizes
(either schedule 40 pipe or smooth I.D. hose) should be ¾” I.D. minimum and 2” I.D. maximum to
ensure that no flow restrictions will occur due to line lengths, high viscosity, etc. When
processing high viscosity oils, the larger sizes of pipe or hose should be used. If tubing is used,
increase the diameter by at least one size. All connections should be tight and free of air leaks.
If a flooded suction to the ThermoJet Oil Purifier is not practical, ensure that the suction height
from the reservoir drain to the inlet connection of the ThermoJetis no more than 8 feet (2.4
meters) above the minimum oil level in the reservoir.
If the suction lift exceeds 8 feet (2.4 meters), install a foot-valve or foot-pump to ensure that the
suction pump will prime and hold prime during long-term service.
NOTICE:
Even very small air leaks can dramatically affect pump suction
performance. If air bubbles are visible in the sight glass after flow is
established, re-tighten all suction connection points.

Ensure that the oil return connection is above the oil level in the reservoir to prevent back flow
and flooding of the separation tank when the ThermoJetis not operating. Return oil must be
introduced into the reservoir above the oil level to prevent siphoning when the ThermoJetis not
operating.
To prevent the potential risk of static electricity ensure that free falling oil does not exceed 6
inches (150 mm). If the oil return level exceeds 6 inches (150 mm), insert a guide baffle to
smooth out flow to the oil surface in the reservoir.
Even if the ThermoJetis to be installed temporarily, it should be hard-piped for safety reasons.
Hoses are acceptable if they are certified not to collapse under vacuum conditions and are rated
for 600 PSIG (42 bar) at 200o F (100oC).
Since all wetted parts of the ThermoJetare constructed of type 300 stainless steel, it is
recommended (but not mandatory) that connecting hard pipe work is also stainless steel.
In accordance with good piping practice, the use of joints, bends, and unnecessary long pipe runs
should be minimized. Elevated sections of suction piping in horizontal runs also must be avoided
to prevent air pockets from existing.
Connect the suction line to the reservoir low point drain, or to existing purifier connections if the
reservoir is constructed in accordance with API 614.
When a flooded suction is provided to the ThermoJet Oil Purifier, recommended practice is to
install a manual shut-off valves (if one does not already exist) directly onto the reservoir
connection routed to the ThermoJetinlet connection.
If the oil reservoir is located below the ThermoJetoil inlet connection, a manual shut-off valve is
not required or desirable since it creates a line restriction unnecessarily.
The discharge line should be connected above the oil surface and at the opposite end of the
reservoir versus the suction connection to ensure optimum circulation of oil through the
ThermoJet. An oil purifier return connection will exist if the reservoir is constructed in
accordance with API 614.
NOTE: Do not install any valves or other restrictive devices in the discharge line which could
cause back flow and flooding of the unit.
Choose a central convenient location, allowing enough room to connect oil supply and return
piping and electrical services. Ensure that unrestricted operator access is maintained at the front
of the unit when the cabinet door is open for system operation and ease of access to the
electrical control enclosure..
The ThermoJet Oil Purifier has maintenance access doors on the front of the cabinet. Ensure that
unrestricted access is provided for system troubleshooting and maintenance.
NOTICE:
Ensure that the supply connection to the ThermoJet Oil Purifier is not
adjacent to or near any oil return connection in the oil reservoir being
services. This could result in oil frothing.
