INTRODUCTION

Our equipment, as described in the manual, has been designed for use by properly trained personnel.
It is important that all relevant information, relating to our equipment, be distributed to employees who
may handle or come into contact with it. In particular, we would stress the importance of standard,
commonsense rules and adherence to normal, safety standards and procedures. (For example, any
covers or enclosures should only be removed by trained personnel.) Please ensure that all those involved
in the operation of this equipment are knowledgeable of the design criteria and that it is used in
accordance with the instructions and recommendations contained in this manual. If there is any doubt

whatsoever relating to the proper use of this equipment, we’ll be pleased to assist you with
technical data, etc.

The fluidized bed is housed in a circular container manufactured from 0.075" (14 gage) stainless steel.
This container is surrounded by electrical heating elements and housed in a square insulated case. The
temperature of the fluidized bed is set and maintained by digital PID temperature controller, which is
governed by the electrical signal from a type "K" (chrome/alumel) thermocouple placed along the
fluidized bath container inner wall. Current to the heating elements is switched on and off by means of
solid state relay actuated by the temperature controller. The controller has a resolution of 1º and can be
switched between ºC and ºF.

The FFB51 and FFB52 are supplied with an internal contactor that disables power to the heaters in the
event that one of the following conditions occur; thermocouple failure, loss of power to or controller
fault and/or exceeding the factory set high temperature limit of 620°C(1148°F). The controller will
flash a message when one of these conditions has occurred and can be reset for operation once the
situation is corrected. See page 6 for more details on the PID temperature controller.

The air supply to the bed must be clean and dry. An air filter and pressure regulator can be supplied as
optional equipment (Omega Part No. 6035915).

The Omega Industrial Fluidized Bath has been specially designed for removing plastic residue from
extruder and molding machine tools, paint build up and carry out various heat treatment processes.
When used for burning plastic residues, the “FFB’s” should be installed with an adequate fume
extraction system. A fan and fume extraction collar can be provided, along with other fume cleaning
equipment.

FUME CLEANING

When the Industrial Fludized Bath is installed with a fan and exhaust ducting system, fumes will be
removed from the top of the fluidized bed.

INSTALLATION & SETUP

1) The bath should be placed in a location that is level and dry.

2) Connect a 30 PSI air supply to the input that is capable of delivering 5 CFM maximum flow. The

supply should be dry and free of particulate. A 6’ length of tubing should be used to connect the
air supply to the bath. The tubing and any fittings should not be less than 1/2” ID at any one
point or bath performance may be reduced.

3) Wire up the bath to your 220 to 240 volt single phase power supply. A 208 volt supply is too

low and should be boosted to 230 volts with a boost transformer. The catalog number for the
boost transformer that has a rating of 7200VA for use with the FFB51 and FFB52 is 7032838.

4) Fill the bath with Aluminum oxide sand to within 3 or 4 inches of the top. Fill with sand before

placing the extraction collar into the bath.

5) Turn on power and air to the unit. Set the air flow per the front label to 4 CFM when at ambient

temperature. When Fluidized and bubbling make sure the Aluminum oxide sand level is still
within 3 or 4 inches of the top.

6) Place the extraction collar (if purchased) into the bath and place the lid on. Set the controller to

your operating temperature.

7) Important; as the bath heats up you will need to adjust the air down based on the front label

chart settings or the heat up time will greatly increase. The reverse needs to happen when cooling
down.

8) Once the controller has reached your set point allow 1 hour for the bath to fully stabilize before

attempting to use it. (IF YOU ARE NOT CLEANING TOOLING JUMP TO LINE 13)

9) With your first tool cleaning start with a smaller number of tools and at a lower temperature.

Adjust the bath set temperature and the number of tools cleaned based on your expected results
and the amount of time required. It is always a good idea to clean at the lowest possible
temperature.

10) Extraction Air setup; if you use an exhaust hood for ventilation this step doesn’t apply to you.

a. Make sure the exhaust system is plumbed according to our recommendation in the

manual.

b. With the exhaust fan on, close the damper so there is no extraction to the bath
c. Put parts in basket and lower into the bath
d. Place lid on the bath
e. When smoke and fumes start to come up and around the lid slowly open the damper just

to the point where they are pulled back into the bath and no longer entering the room,
then stop adjusting.

f. This setting will give good results with minimal heat and sand loss.

11) After repeated tool cleanings heavier clumps and larger particulate should be sieved from the

sand.

12) In time the sand may become dense and fluidize poorly at which point it should be replaced.

13) The bath air supply and power can be turned off after the temperature has cooled to 200ºC/400ºF

Alternatively if used daily reduce the overnight temperature to 300ºC for quicker startup

AIR ADJUSTMENT

Set the inlet air pressure to a value of 30 psi. Use the factory default air flow settings below as viewed
on the air flow meter to obtain optimum bath results. Note that the air flow must be adjusted while
cooling the bath also as indicated.

BATH TEMPERATURE

The bath should allowed to stabilize for at least 1 hour after the controller has reached the setpoint
temperature before placing parts to be cleaned into the bath. An initial temperature drop or quenching of
the bath can occur after inserting a workpiece to be cleaned. This temperature drop depends on the size
of the immersed object, but is generally in the order of 77°F (25°C). Carbon is burned to carbon dioxide
quickly above 752°F (400°C). It may be found desirable to pre-heat the bath to as high as 1020°F
(550°C) in order to obtain quick results, but caution should be exercised not to damage tools by
overheating.

PID TEMPERATURE CONTROLLER

The control parameters in the PID temperature controller have been optimized by the factory during
manufacture to give the best results for most applications. Per the image below use the “scroll” button to
navigate to the menu option UNITS for changing display from ºC to ºF and vice versa.
Two setpoints can be entered for future recall, press the “scroll” button to access SP1 and SP2. Set a
different setpoint in each of these. Then “Scroll” to SP.SEL to select either setpoint SP1 or SP2. The
up/down buttons are used to set the bath setpoint temperature. If an alarm indicates an overtemperature
condition or thermocouple failure the two buttons labeled as ACK need to be depressed together after
the alarm condition is corrected. If the alarm cannot be cleared please contact the factory for support.

OPERATION

The industrial fluidized baths detailed in this booklet were designed specifically for "burning off"
residue from plastic machinery tools. However the FFB baths are also a good choice for many heat
treatment, reactive chemistry and exothermic reaction type of applications.
Our systems are effective on the full range of plastics, including polyethylene, polypropylene, PVC,
nylon, polyester, polycarbonates, acrylic, polystyrene and acetyl. In addition, they are effective with
rubber, EPR, epoxy resins and acrylic paints. They provide a safe, dry and fast means of removing all
plastic residue with a minimum amount of effort and physical contact with the tools. The "burning off"
operation is controlled at a uniform temperature so that distortion is avoided. Furthermore, as the
fluidized bath is non-abrasive, physical damage to parts is minimal. Each of these factors extends tool
life.
The cleaning process itself is very simple using the heat transferred from the fluidized bath to the tools
to degrade the plastic residue. Objects to be cleaned, supported in a wire basket for ease of handling, are
placed in the fluidized bath, operating at a temperature between 842°F (450°C) and 1020°F (550°C)
depending on the polymer, for approximately 20 to 30 minutes. Actual burn off times and temperatures
vary depending upon the weight, complexity and material composition of the item to be cleaned, in
addition to the quantity of residue to be removed. Our technical staff will always advise on specific
applications.

THE CLEANING PROCESS

The first two thirds, of the total time required for tool cleaning, sees the plastic reduced to a tar mix
state. In this phase, all the initially combustible products of the plastic leave the bath through an
appropriate fume extraction system. In the last third of the immersion time, the tar mix state is reduced
to carbon which either burns away or remains loosely bound to the tool. In the latter case, it can be
blown away or brushed off without causing damage, after the part is removed from the fluidized bath.
The clean item can then be put to one side, preferably on a steel plate, to cool before refitting on a
machine or returned to the tool store. In some cases, particularly with dies from blow molding machines
using PVC, a further operation of polishing with a soft cloth may be required.

The aluminum oxide fluidizing medium is not degradable but will need to be replenished due to loss
from spillage or extracted in the exhaust. In the particular case of PVC, chlorinated hydrocarbons
remain in the fluidized bath after burn off which dictates special maintenance procedures.

CAUTION

Care should be taken when handling hot parts which have been removed from a fluidized bath. We
recommend that protective clothing (safety glasses, etc.) be worn when working with fluidized baths and
that the installation and maintenance procedures outlined in this booklet be followed explicitly.

MAINTENANCE

The aluminum oxide, not being degradable, will only require replacement when losses occur due to
attrition, spillage or contamination with inert pigments, filler or acidic by-products from the burn-off
process.

On at least daily intervals, the bed should be cleaned of floating residues by means of a wire mesh hand
scoop. This procedure removes carbon char which impairs fluidization and acts as an absorbent. More
importantly, it can also remove uncharred plastic and so reduce the quantity of fumes produced and the
time of processing.
The optional air-line filter into the bed is self-draining. However, it should be kept in good condition by
inspection at two week intervals and by cleaning the bowl and washing or replacing the filter element as
necessary. With exceptionally dirty or wet air supplies this frequency may have to be increased. Fe
water or water vapor in the air supply is a notorious source for the production of hydrochloric acid in the
bed when PVC is burned off. In addition, oil vapors in the air supply which reach the fluidizing plate
are carbonized within the pores of the plate, quickly causing blockage and consequent poor fluidization.

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
plastic, instead of being burned off in a fluidized state, could perculate down through a static bed and
settle on the porous plate causing blockage and poor fluidization.
When parts are removed from the bed, they should be allowed to cool in the air and, while still warm,
wiped with on oily cloth to prevent rusting.If the bath is left unused for long periods of time, empty the
aluminum oxide and store it in a separate container. Keep the inside of the bath clean and dry.

SPECIAL MAINTENANCE PROCEDURES FOR OMEGA INDUSTRIAL FLUIDIZED BATHS
WHEN BURNING OFF PVC OR OTHER HALOGENATED POLYMERS

Burning off PVC (polyvinyl chloride) in a fluidized bath offers one of the most severe conditions of
operation. Hydrogen chloride (HCl) liberated on the breakdown of PVC is absorbed by the bed medium
creating an acidic environment within the bed. This happens especially when the bed also absorbs water
from the atmosphere or when the fluidizing air is cold. HCl is extremely corrosive, especially when it is
aerated and wet. In addition, in water it produces chloride ions which, even in neutral or alkaline
solutions, promote corrosion and rusting in steel. Witness, for example, the corrosive nature of sea
water and calcium chloride road de-icer.

Consequently, fluidizing beds used for burning off PVC require strict supervision to minimize corrosion
of the bed itself and of parts cleaned in it, especially if these are of un-coated steel. The purpose of most
of the recommended maintenance procedures is aimed at keeping the bed medium clean, free-flowing,
free of gums, acids, agglomerates, partly decomposed plastic, char and larger particles. These cleaning
processes have the additional benefit of ensuring good fluidization and thus good heat transfer
throughout the bed and through immersed parts. This, in turn, reduces burn-off time, uneven heating of
parts and thus distortion, increases heater life by eliminating localized hotspots and makes cleaning
easier on a regular basis.

The following procedures are essential when PVC is burned off on a regular basis, but they can also be
followed profitably by users of other plastics.

The bed should be completely emptied at monthly intervals and visually inspected for signs of corrosion.
Examination should include the walls of the inner cylinder, the porous fluidizing plate, the thermocouple
sheath and the loading baskets with particular emphasis on exposed weld lines. Serious corrosion
should be dealt with immediately by improving maintenance procedures or by replacing the inner
container before holes appear and cause failure of the heating element and corrosion in more
inaccessible parts.

The fluidizing media should be screened by passing through a 50 to 70 mesh sieve on at least monthly
intervals to remove foreign bodies, agglomerated gummy material and, periodically, be completely
changed for a new charge of aluminum oxide.

During shutdown overnight or over the weekend, the temperature should be reduced to 212°F (100°C) to
ensure that the moisture from the atmosphere is not condensed into the bed to create a hydrochloric acid
solution. Fluidizing air may be turned off in these circumstances but it is better that it should be
continued when it is practical to do so. For extended shutdowns exceeding two days, the medium
should be removed and the inside of the bath wiped out with a rag wetted with a 5% washing soda
solution (sodium carbonate).

FAULT FINDING

If the heater indicator fails to go off, the unit fails to reach its operating temperature or heat up rate
decreases, check:

1) Fluidization – remove aluminum oxide from bath leaving approximately 2 inches in the
bottom. If an area ¼ or more is not bubbling then most likely the porous plate is blocked
and should be replaced. Check that the porous plate is not blocked with plastic residue or
other material.

2) Heater - Empty medium from the bed and disconnect the main supply. Turn the unit
upside down and check the resistance of the heater. If one or more heater windings are
faulty, replace the heater. Reassemble in the reverse order.

3) Thermocouple – check with an instrument that can measure and simulate thermocouple
signals to verify its operation.

4) Controller and/or SSR – the controller will output a DC signal to the SSR when heat is
called for. If the SSR is receiving a DC control signal but not passing power to the
heaters then it should be replaced. Alternatively a problem may exist with the controller.

If the fluidization deteriorates, check the air filter assembly for clogging of the filter element; if
necessary, replace the element. If the fault remains, run your bath at 1100°F (600°C) for a period of one
hour to allow any accumulated residue in the bath to burn off. If the fault still remains, empty the
medium from the bed, check the stainless steel porous plate for damage due to clogging by plastic
residue, distortion of the plate or corrosion.
