Principal of Operation
The ThermoJet Oil Purifier works on the principal of air stripping. The use of air 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 stripping practical and efficient because of the mixing and intimate contact of the air with
the fluid being cleaned. In addition, the ThermoJet
utilizes the principal that the capacity of
air 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 40
o
C (100
o
F) minimum
temperature at the inlet to the ThermoJet during start-up.
Dewatering
The ThermoJet
®
removes dissolved and emulsified water from industrial lubricants. The
ThermoJet
returns the viscosity of the lube oil and restore it to like new levels. No longer is
there a need to dispose of water laden 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 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 30 PSI ( 2 BAR). From the filter the oil passes
through the heater that elevates the oil to 180° F (82° C).
The electric heater temperature is set and controlled with a solid-state temperature controller
whose operation is viewed through a window on the electrical control box. After the heater,
the oil passes through the heart of the ThermoJet, 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 into the heated oil
stream as delivered to it by the inlet pump. The ambient air becomes intimately mixed with the
oil and assumes the temperature of the oil and absorbs water from 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 expands and leaves the oil thus cleansing the oil of water.
Return of Clean Oil
In the separation vessel the oil from the jet mixer cascades down trays to promote the release
of the water laden air. 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.
Mounting Options
The ThermoJet Model H2000
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. See the H2000E Model Code sheet for additional mounting options.
