About
industrial  uidized baths
After years of demonstrated success, plastic manufacturers have come to depend on Techne  uidized baths for safe, e cient and cost e ective cleaning of
tooling, components, systems and parts (dies, breaker plates, nozzles, tools, tips, spinnerets, extruder screws, manifolds, etc.) Fluidized baths will remove
almost all polymers, including plastic, paint, epoxy, rubber and adhesives, as well as other hydrocarbon-based products such as oils,  uids, grease, lubricants
and coatings. Parts immersed into a  uidized bath are cleaned by the high temperature (up to 600°C/1112°F) environment within a bath media of  uidized
aluminum oxide that instantly starts to degrade plastic to carbon, which then leaves the bath as CO
2. This instant heating and minimized quenching results in
shorter cleaning times than those of ovens, and when paired with the even and consistent heat of the bath, results in greatly reduced metal fatigue and tool
damage.
How They Work
A  uidized bath consists of a loosely packed mass of solid particles through which an upward  ow of air is passed. In the  uidized state, the aluminum
oxide particles become mobile and the bath as a whole, displays many of the properties of a liquid. However, since the bath is composed of tiny, inert
aluminum oxide particles, freezing, boiling and evaporation are totally eliminated. Heaters on the outside wall of the bath inner container radiate heat into
the aluminum oxide; Fluidization acts as the stirring mechanism to evenly distribute heat throughout the bath, resulting in excellent thermal stability and
uniformity. These advantages make  uidized baths a cost e ective and environmentally friendly safe alternative to oil, salt, ultrasonic and molten metal
baths, ovens and furnaces.
Details & Facts
The following pages give complete speci cations on the seven models we o er in the Industrial Fluidized (IFB) bath product range. The basic di erences
are dimensions, capacity, heater power, air supply and power required. For burno applications, a gas  red AB-100 Afterburner is o ered for incineration,
to further reduce exhaust particulate and VOC’s. To assist in cleaning the exhaust when PVC’s and other halogenated polymers are burned o , the SR-100
Scrubber can be employed.
The baths can be  uidized with either compressed house air or an inert gas such as nitrogen or argon. It should be noted that  uidized baths and the action
created in the aluminum oxide is not abrasive to items immersed for normal cleaning or heat treatment times. Typical cleaning times range from 30 minutes
to 2 hours depending on bath temperature and amount of material to be cleaned. The speci c heat of aluminum oxide is 0.21. Typical heat transfer rates for
 uidized baths range between 60 to 120 Btu/hr/sq ft/deg F.
Other Applications
The excellent thermal performance of Techne Industrial Fluidized Baths make them a good choice for basic heat treatment, test and calibration as well as
reactive analysis. Some of these applications include tempering, shape setting, annealing, Nitriding, distillation, curing, exothermic and endothermic
reactions, and thermal analysis of devices, components and materials.

IFB-51 & IFB-52
Models IFB51 and IFB52 Industrial Fluidized Baths are our most popular units due to their economical price and smaller size. They o er a front panel
mounted Rotameter for adjustment of the  uidizing air  ow and are ready for use out of the box with the included charge of aluminum oxide.
IFB-101 & IFB-111
Models IFB101 and IFB111 step up in diameter and depth from the IFB51 and 52. These baths also have a 3 phase voltage supply requirement to handle the
large power capacity of the heaters. All larger baths on the following pages also run on 3 phase power.
IFB-201
Model IFB201 o ers a rectangular opening for oblong or non-typical parts cleaning and heat treatment.
