Introduction
Please read all the information in this booklet before using
the unit.
Warning
HIGHTEMPERATURESAREDANGEROUS:they
can cause serious burns to operators and ignite
combustible material.
Techne have taken great care in the design of
these units to protect operators from hazards, but users
should pay attention to the following points:
• USE CARE AND WEAR PROTECTIVE GLOVES TO
PROTECTHANDS;
• DO NOT put hot objects on or near combustible
objects;
• DO NOT operate the unit close to inflammable liquids or
gases;
• DO NOT place any liquid directly in your unit;
• At all times USE COMMON SENSE.
Operator Safety
All users of Techne equipment must have available the
relevant literature needed to ensure their safety.
It is important that only suitably trained personnel operate
this equipment, in accordance with the instructions
contained in this manual and with general safety standards
and procedures. If the equipment is used in a manner not
specified by Techne the protection provided by the
equipment to the user may be impaired.
All Techne units have been designed to conform to
international safety requirements and are fitted with an
overtemperature cut-out. On some models, the cut-out is
adjustable and should be set to suit the application. On all
other models the cut-out is preset to protect the unit.
If a safety problem should be encountered, switch off at
the mains socket and remove the plug from the supply.
Installation
1. All Techne units are supplied with a power cable. This
may be integral or plug-in.
2. Before connecting the mains supply, check the voltage
against the rating plate. Connect the mains cable to a

The fused plug supplied with the mains lead for use in
the UK is fitted with the following value fuse to protect
the cable:
230V UK 10 AMP
The fuse in the unit protects the unit and the operator.
Note that units marked 230V on the rating plate work at
220V; units marked 120V work at 110V. In both
cases, however, the heating rate will degrade by
approximately 8%. The rating plate is on the rear of
the unit.
3. Plug the mains cable into the socket on the rear of the
unit.
4. Place the unit on a suitable bench or flat workspace, or
in a fume cupboard if required, ensuring that the air

WARNING
Poor fluidisation causes hot spots, heater failure, and damage to other parts.
Follow instruction book carefully. For correct fluidisation, pay attention to;
INSTALLATION
Ensure bath is level and air supply is adequate.
OPERATION
Adjust air valve for even fluidisation.
Do not insert objects larger than recommended.
Ensure objects do not lie in contact with container wall or porous plate.
MAINTENANCE
Regularly inspect and maintain air filter to eliminate oil vapour in air supply.
ALUMINA
Should the fluidised bath be stirred for a long period of time under damp or humid
conditions, moisture may be absorbed by the alumina which is hydroscopic. To avoid violent
fluidisation which occurs when damp alumina is heated above 100°C, operate the bath for a
period of approximately 8 hours at 90°C prior to operation at elevated temperatures.
NEVER ADD COLD OR DAMP ALUMINA TO A HOT BATH AS THIS WILL ALSO
CAUSE VIOLENT FLUIDISATION WHICH CAN BE DANGEROUS. Allow the bath to cool then
add the fresh alumina. If this fresh alumina is a large portion of the charge then dry the whole
charge as above.
FUME EXTRACTION
When used for processing items which may emit toxic or inflammable fumes, it is
essential that an adequate fume extraction system be installed. The extraction system must
be correctly sized to ensure that any toxic fumes are removed from the working environment.
To eliminate the risk of spontaneous ignition, the concentration of inflammable
fumes above the bath and within the exhaust duct work must be kept below the lower explosive
limit.

GENERAL DESCRIPTION
The fluidised bath employs the principle of fluidisation of a mass of finely divided
inert particles by means of an upward flow of gas. A state of fluidisation is achieved when the
individual particles become microscopically separated from each other by the moving gas. This
“fluidised bed” of particles has unusual properties which differ markedly from either those of the
gas or of the solid particles. Instead, the fluidised bed behaves remarkably like a liquid,
exhibiting characteristics which generally attribute to a liquid state. For example, the fluidised
bed can be agitated and bubbled; it always seeks a common level; materials of less density will
float while those with densities greater than the equivalent fluidised bed density will sink; and,
most important, the heat transfer characteristics between the fluidised bed and a solid interface
can have an efficiency approaching that of an agitated liquid.
In addition, the fluidised solid phase has a most unusual physical behaviour, in that
its basic characteristics change only slightly over very large temperature ranges; it has no
melting point and no boiling point. The lowest temperature available is the liquefaction point of
the gas used for fluidisation, while the high temperature level is usable temperature of the inert
solid. Various metal oxides with allowable temperatures of over 1700°C are readily available.
The metal oxide beds commonly used, (Eg aluminium oxide) are non-flammable, non-explosive
and non-toxic.
The most commonly used fluidised gas is ordinary compressed air obtained from a
blower or compressor. For situations where a non - oxidising atmosphere is required, nitrogen
can be utilised and if a reducing atmosphere is required, cracked gas can be employed with a
silicon carbide bed.
The unique characteristics of gas fluidised particles is the relatively high rate of heat
transfer which yields highly isothermal conditions, as well as excellent heat transfer to solid
surfaces. This characteristic is due to the turbulent motion and rapid circulation rate of the solid
particles in conjunction with the extremely high solid gas interface area. Therefore, despite the
fact that gas solid interfaces normally yield low heat transfer coefficients and the solids normally
have low thermal conductivities, the overall heat transfer characteristics of fluidised particles
approach those of a liquid.
The combination of excellent heat transfer characteristics and high heat capacity
are ideal for attaining rapid stabilisation at an isothermal condition.
Techne industrial fluidised baths use aluminium oxide as the fluidising medium.
They have been designed to remove plastic residue from extruder and moulding machine tools,
paint build up from paint fixtures, and carry out various heat treatment processes.
The fluidised bed is housed in a circular stainless steel container which has an
effluent gas extract duct and fluidised medium drain chute. The container is surrounded by
electrical heating elements which are enclosed within thermal insulation. The inner assembly is
housed in a square outer case which also supports the electrical and pneumatic control
console.
The following control options are available:
A manual control system which consists of a temperature controller, an independent
over-temperature cut-out device, a fluidising air pressure interlock, and a manually adjusting
fluidising air control valve. Supplied as standard with this, and all other options, is an air
pressure regulator and filter assembly.

I F B - 1 0 1 O P E R A T O R ’ S M A N U A L
PAGE 10
During operation the correct fluidising air flow must be determined by visually
inspecting the surface of the fluidised bath. When the fluidised bath is heated the air within the
bath expands; it is therefore necessary to decrease the amount of air supplied to the bath during
the heat up period to ensure that the bath is correctly fluidised at all times.
A control system with automatic air control is also available. This system is
designed to automatically adjust the fluidising air flow rate as the bath heats up. This allows the
system to be operated without supervision and is useful in applications where it is
advantageous to preheat the bath prior to the start of the working day.
The system is programmed to feed a set amount of fluidising air to the bath between
room temperature and 200°C. When the bath reaches this temperature, the amount of air feed
to the bath is reduced and held at constant value until the temperature of the bath exceeds
400°C, at which point a further adjustment is made.
A non-standard version of this industrial fluidised bath is available for applications
where continued treatment of components contaminated by PVC and other halogenated
polymers is envisaged. This version is manufactured from materials that resist the effects of
corrosion which are experienced when processing the above polymers.
The compressed air supply to the fluidised bath must be clean, dry, and free from
oil.
When used for processing items which may emit toxic or inflammable fumes it is
essential that an adequate fume extraction system be installed.
The extraction system must be correctly sized to ensure that any toxic fumes are
removed from the working environment.
To eliminate the risk of spontaneous ignition the concentration of inflammable fumes
above the bath and within the exhaust duct work must be kept below the Lower Explosive Limit.
A later section of this manual details the various fume treatment equipment that is available, and
how it should be installed and adjusted.

INSTALLATION
Mount the fluidised bath in the position where it is to be used. It is important to
ensure that the bath is level, otherwise it will fluidise incorrectly. This will lead to the formation
of large temperature gradients across the bath which results in premature heater failure and
possible damage to the porous plate and inner container assemblies.
Connect any associated fume treatment equipment to the fluidised bath effluent gas
extract duct. See section which follows on Fume Cleaning.
Check that the heater isolation resistance (measured from the load side of the solid
state relay, to earth) is at least 2.5M ohm before connecting the electrical circuit to the electrical
supply. See attached circuit diagram for connection details and the unit rating plate for details
of the electrical supply required.
The compressed air supply to the fluidised bath must be clean, dry, and free from
oil.
If a manual control option is fitted, close the air flow adjusting valve which is situated
on the front of the control console, and connect the air inlet port at the rear of the control
console to a suitable dry, clean air supply. Make sure that the pressure delivered to the fluidised
bath is between 204kPa (30psi) and 1030kPa (150psi), and that the compressed air line is
capable of supplying sufficient air to fluidise the bath (see specification details).
Fill the fluidised bath with a sufficient quantity of aluminium oxide so that, when
fluidised, the distance between the top of the aluminium oxide and the top of the bath is 390mm.
Should the fluidised bath be stored for long periods of time under damp or humid
conditions, moisture maybe absorbed by the alumina which is hydroscopic. To avoid violent
fluidisation which occurs when damp alumina is heated above 100°C, operate the bath for a
period of approximately 8 hours at 90°C prior to operation at elevated temperatures.
NEVER ADD COLD OR DAMP ALUMINA TO A HOT BATH AS THIS WILL ALSO
CAUSE VIOLENT FLUIDISATION WHICH CAN BE DANGEROUS. Allow the bath to cool then
add the fresh alumina. If this fresh alumina is a large proportion of the charge then dry the
whole charge as above.
Set the air pressure regulator, which is situated within the pneumatic section of the
control console to 204kPa (30 psi).
Units fitted with the automatic fluidising air control system require no further
adjustment. Other systems require adjustment of the air flow adjustment valve which is
situated on the fascia of the control console. Adjust the air flow so that the fluidised bed lifts and
fluidises evenly across with bubbles of approximately 50mm diameter. It is important to ensure
that the bath is correctly fluidised.
If the air flow is too small, uneven fluidisation will result in poor heat transfer and
large temperature gradients across the bed. If the air flow is too large the fluidisation will
become violent and an excessive amount of fluidising medium will be lost from the bed.
The following table shows the recommended fluidising air flow rates which should
be used to achieve the correct level of fluidisation.

200°C to 400°C 110 l/min

The figures quoted are approximate and may need to be varied depending upon the
work load, e g the bath may have to be over fluidised to avoid the creation of dead spots above
an immersed object. For details of how to adjust the fluidising air flow rate when using the
automatic air control system, see Item c) of the Fault Finding Section of this manual.
To safeguard the fluidised bath from damage, two safety features are included in the
control console: an adjustable over temperature cut-out which guards against controller failure,
and an air pressure switch which inhibits operation if the compressed air supply to the fluidised
bath fails. Both of these devices isolate the electrical supply to the heater elements and
illuminate the cut-out indicator in a fault condition. The over temperature cut-out is factory preset
at 630°C. Under no circumstances should this setting be increased, but lower limits may be set
to safeguard particular processes in the fluidisation bath.
If the fluidised bath is to be used to process items that may emit toxic or
inflammable fumes, it is essential that an adequate fume extraction system be installed. Details
of fume cleaning equipment are contained in the following section of this manual.
The extraction system must be adjusted during initial operation for optimum
extraction in line with the following instructions:
a) Heat the fluidised bath to the operating temperature a recommended later in this manual,
ensuring that the fluidising air flow rate is adjusted in accordance with the above table.
b) Switch on the fume extraction system.
c) Immerse a typical component that is to be treated into the fluidised bath; do not exceed the
stated loading capacity, see Technical Specification for details.
d) Adjust the overall fume extraction rate by adjusting the setting of the damper valves built into
the fume extraction system so that adequate fume removal occurs over the surface of the
fluidised bath. The velocity of the extraction system should be just sufficient to entrain the
maximum quantity of fumes produced above the bath. If high extraction velocity misused, an
excessive amount of fluidising medium will be entrained by the extraction system.
e) Measure the fume concentration within the fume extraction system using an explosimeter
and ensure that the Lower Explosive Limit (LEL) is not exceeded. The fume concentration
should be diluted by fitting a dilution tee into the extraction ductwork directly after the fluidising
bath. Air may then be induced into the system to dilute the effluent gases. It is
recommended that the maximum fume concentration be less than 25% of the LEL.
f) Measure the fume concentration in the working environment adjacent to the fluidised bath
using suitable gas analysis equipment such as “Drager” tubes, to ensure that any toxic
fumes generated within the fluidised bath have been diluted so that the fume concentration is
below the threshold limit value. Recommended Threshold Limit Values (TLVs) are available
in publications such as the Health and Safety Executives Guidance Note EH15/76 in the UK,
a copy of which is available from Techne on request.

Fume Ignition
Spontaneous ignition may occur above the surface of the fluidised bath or within the
exhaust ductwork if the concentration exceeds the lower explosive limit.
The fume concentration is dependent upon the rate of fume production in the
fluidised bath and the level of dilution achieved by entraining air from above the bath or through
the dilution tee.
The rate of fume production is dependent upon the type and amount of material
being treated and the temperature of the bath.
To ensure that the concentration of inflammable fumes is below the lower explosive
limit, ensure that the amount of combustible material immersed in the bath at any one time is
within the design capacity of the extraction system.
Ensure that the temperature of the bath is at minimum level to which satisfactory
results can be achieved. Increased working temperatures result in increased fume
concentration. By way of example, an extraction rate of 2m3 /min is required to ensure that the
fume concentration is below 25% of the lower explosive limit when thermally decomposing 1kg/
hr of polythene at 450°C.
To safeguard the fluidised bath from damage, two safety features are included in the
control console: an adjustable over temperature cut-out which guards against controller failure,
and an air pressure switch which inhibits operation if the compressed air supply to the fluidised
bath fails. Both of these devices isolate the electrical supply to the heater elements and
illuminate the cut-out indicator in a fault condition. The over temperature cut-out is factory
preset at 630°C. Under no circumstances should this setting be increased, but lower limits may
be set to safeguard particular processes in the fluidised bath.

Fume Cleaning
When used for processing items which may emit toxic or inflammable fumes, it is
essential that an adequate fume extraction system be installed. A typical schematic diagram of
such a system is shown in the appendix; the system consists of the following components:-
Ductwork to connect the fluidised bath extract duct via the various fume treatment
equipment to the input of the fume extraction fan. The ductwork should include an air dilution
tee, positioned as close as possible to the fluidised bath. The dilution tee enables the fumes
within the system to be diluted with air. The ductwork should also include a damper valve which
is normally positioned adjacent to the extraction fan. This valve allows the extraction velocity to
be reduced. In general the ductwork may be manufactured out of galvanised mild steel;
however, in installations where PVC or other halogenated polymers are being processed, it is
recommended that stainless steel ducting is used.
The ductwork should be as short as possible and contain the minimum number of
bends and horizontal runs so as to reduce the possibility of a blockage.
A cyclone separator should be mounted directly after the dilution tee. The cyclone
removes any fluidised medium that may be present in the extracted fumes. The fluidised
medium is collected in the cyclone collection bin from where it may be returned to the fluidised
bath.
In applications where the components being cleaned are contaminated by polymers
which contain inorganic pigments or fillers such as titanium oxide, of a particle size less than
0.005mm diameter which will not be retained by the cyclone, it is recommended that a filtration
system be fitted after the cyclone.
In applications where the materials being treated produce acidic vapours during
thermal decomposition, it is recommended that a fume scrubber be utilised to ensure that the
final fume emission from the plant conforms with local regulations. A caustic dosing system
may also be required to ensure that the scrubbing liquid is maintained at an acceptable pH level.
An extraction fan is required in all applications to provide the motive force for the
exhaust. In applications where it is not permissible to emit visible smoke from the plant or
where local regulations specify the maximum fume concentrations that may be emitted from an
exhaust stack, an afterburner may be required. The afterburner heats the fumes to a point
where thermal incineration eliminates the visible content of the fumes while reducing the fume
concentration.Finally, an exhaust stack is required to direct the treated fumes away from the
working environment. The exhaust stack will generally be manufactured out of the same
materials as the ductwork system. However, in installations where an afterburner is fitted, the
exhaust stack should be manufactured out of insulated stainless steel.
The exact combination of fume treatment components required depends upon the
application and local conditions. Technical staff are available to discuss particular applications
and offer advice as to which combination is required.
Techne are able to offer the following fume treatment equipment:
Cyclone
Scrubber
Caustic Doser

OPERATION
To set the temperature controller to the required operating temperature, switch on
the electrical supply which will illuminate the power and cut-out indicators. Then set the
required temperature, either by using the thumbwheel on the Eurotherm 101 or the up and down
arrows on the Eurotherm 807. Depress the reset switch to initiate the system and extinguish
the cut-out indicator.
The following control parameters have been factory pre-set on the Eurotherm 807:-
High Alarm Hi Al 600°C 1112°F
Low Alarm Lo Al 20°C 68°F
Deviation Alarm D. Al 600°C 1112°F
Proportional Band P 7% 7%
Integral Time I 124 secs 124 secs
Derivative Time D 3 secs 3 secs
Heater Cycle Time HCT 0.3 secs 0.3 secs
High Cut Back HCB 20°C 36°F
Low Cut Back LCB 20°C 36°F
If your unit is fitted with a Eurotherm 2208L controller, the parameters are factory set
and should not be changed.
As the fluidised bath heats up the fluidisation will become more vigourous, due to the
expansion of the fluidising air. Units fitted with the automatic fluidising air control system will
automatically reduce the air input so as to keep a constant level of fluidisation. Manually
operated units must the fluidising air flow, reduced unit the level of fluidisation returns to its
origional state. The following table indicates the flow rates that are factory set on an auto-air
unit
Ambient to 200°C 160 l/min
200°C to 400°C 110 l/min
400°C to 600°C 70 l/min
The fluidised bath should be operated with the bath lid fitted to reduce heat loss
during the heat up period, and to increase the efficiency of the fume extraction system. As the
temperature of the fluidised bath approaches the set point, the heater indicator, situated in the
temperature controller fascia, will cycle on and off, until the actual temperature reaches the set
point temperature.
It may be desirable, depending on the process being carried out in the fluidised bath,
to check the actual bath temperature with an independent temperature sensor. Any offset in the
temperature may be corrected by adjustment of the temperature controller (an instruction
manual for the temperature controller is included with this manual). Further temperature
checks may be made at various points within the fluidised bath to ensure good temperature
uniformity is being achieved throughout the bed. Slight adjustment of the fluidising air flow rates
will reduce any excessive temperature gradients.
CAUTION: Care should be taken when handling hot parts which have been removed
from a fluidised bath. We recommend that protective clothing (gloves, aprons, and visors, etc)
be worn at all times when working with fluidised baths and that the installation and maintenance
procedures outlined in this booklet be followed explicate.

Special Operating Pprocedures for use when Removing Plastic Residue
The industrial fluidised bath detailed in this manual is suitable for “burning off” plastic
residue from plastic machine tools, and is effective on the full range of polymers. In addition, the
bath is also effective on rubber, epoxy resins and various paints. The bath provides a safe, dry,
and fast means of removing all plastic residue with the minimum effort.
The process is controlled at a uniform temperature so that distortion of tooling due
to uneven heating which occurs when using other heating methods is avoided. Furthermore, as
the fluidised bed is non-abrasive, physical damage to parts is minimal.
The cleaning process relies on heat being transferred from the fluidised bed to the
immersed tools, the heat degrading the plastic residue. Objects to be cleaned should be
supported in a basket or suitable holder for ease of handling and lowered into the fluidised bed.
To avoid physical damage and local overheating, it is important to ensure that any items placed
in the bed are supported and not allowed to rest either on the porous plate at the bottom of the
bed or against the wall of the inner container. The bath should be operated generally in the
temperature range of 450°C to 500°C, depending on the polymer to be removed. The process
time depends upon the thermal mass of the object, the amount and type of polymer to be
removed. During the first two thirds of the process time the polymer is reduced to a tar mix, in
this phase all the initially combustible products of the polymer are emitted from the fluidised bath
in the form of fumes that must be extracted and treated by suitable fume handling equipment.
During the last third of the process time the polymer is reduced to carbon which either burns
away or remains loosely bound to the object being cleaned.
Any carbon or incombustible filler that remains on the processed item can be
removed by a secondary cleaning operation, either by brushing or some form of water wash.
It is important to ensure that the items being processed do not exceed the maximum
loading capacity (see Technical Specification) and that they are loaded into the fluidised bath in
such a way that the fluidisation is not impended.
THE PROCESS RELIES UPON GOOD FLUIDISATION TO ENSURE GOOD HEAT
TRANSFER; OVERLOADING OR INCORRECT LOADING OF THE BATH WILL RESULT IN
EXTENDED CYCLE TIMES GIVING INFERIOR RESULTS. LOCAL OVERHEATING MAY ALSO
OCCUR, GIVING RISE TO PREMATURE HEATER FAILURE AND POSSIBLE DISTORTION
OF THE INNER CONTAINER.
The aluminium oxide fluidising medium does not degrade but will need to be
replenished due to loss from spillage or entrainment in the exhaust (from where it may be
recovered by a cyclone trap).
All articles should be completely cleaned and removed from the bed before shut
down. Corrosion of processed parts could be seriously increased if they are left immersed
overnight. Furthermore, residual polymer, instead of being burned off in a fluidised state, could
percolate down through a static bed and settle on the porous plate to cause a blockage and
result in poor fluidisation.
When parts are removed from the bed they should be allowed to cool in air and,
whilst still warm, treated to prevent rusting.
It should be noted that some plastics and, in particular, paints contain fillers. These
fillers are usually inorganic materials and will not therefore burn when put into a fluidised bath,
with the result that the material falls away from the article being cleaned and is retained in the

I F B - 1 0 1 O P E R A T O R ’ S M A N U A L
PAGE 18
bath, either on the surface or at the base of the bath, depending upon the density of the material
involved. If this happens it is recommended that the bath be checked and cleaned at least once
a week or more frequently if the bath is used continuously.
The following table details recommended operating temperatures for particular
polymers. The temperatures quoted should be used as an initial guide.
The ideal operating temperature will vary depending on the size of the components
being cleaned and the amount of material being removed. In general temperatures below
400°C should be avoided to obviate the danger of the polymer melting and sinking to the bottom
of the bath where it may block the porous plate. With some large objects it may be desirable to
preheat the bath to well above the operating temperature so that the polymer temperature
rapidly moves through the melting phase to the burning condition.
Excessive operating temperatures should be avoided as they increase the fume
concentration above the bath and may result in the formation of condensed fumes within the
extraction system.
