Fluidized Temperature Bath

Accuthermal Fluidized Temperature Baths

Accurate Thermal Systems manufactures Fluidized temperature baths to meet a wide range of applications requiring a stable and uniform temperature environment. Fluidized temperature baths have been used for decades to remove organic material from extrusion tooling and other metal surfaces or parts. They are also used to shape set medical devices, for calibrating and testing various sensors and systems, and for heat treatment of metals and heating reactors, coils, flasks, and containers. Fluidized temperature baths provide faster processing times than ovens and furnaces and are more thermally stable and uniform while offering faster heat-up of immersed parts and objects. Fluidized baths are safer to operate than molten salt baths since immersed objects remain clean and dry with no material to remove.

Typical Applications:

Cleaning Parts, Tooling, Machinery, and Hardware

Removing all types of organics, including paint, oil, grease, epoxy, plastic, varnish, insulation, rubber, adhesives, food and plant material, and more. ATS models FTBSL6, FTBLL12, FTBLL12W, FTBLL26, FTBLL27 & FTBLL47 are typically recommended for thermal cleaning applications.

Heat Treatment of Medical Devices, Metals, and Materials

For annealing, tempering, shape setting, high-temperature quenching, and other operations that require fast and uniform heating, we recommend ATS models FTBSL6, FTBSL15, and FTBSL25, depending on specific heat load requirements.

Calibration, Testing, and Reactor Heating

Calibration of temperature sensors, devices, and systems, thermal failure mode analysis testing, and heating of coils and vessels for endothermic and exothermic reactions. Choose any model based on your application’s volume and heat load requirements.

How Does a Fluidized Bath Work?

Fluidized bath technology has been used across various industrial applications for over fifty years. The system comprises a tank or inner container with a chamber at the bottom and a porous plate on top. The tank is filled with aluminum oxide media, and compressed air is fed into the chamber with sufficient pressure and flow to cause air bubbles to break the surface of the sand and rise upwards through the porous plate. Heat is radiated into the sand either directly or indirectly from the heater. Air constantly flows into the bath to mix and stir the heated media for consistent and stable thermal results. The “bubbling” media provides thermal and displacement properties similar to that of a fluid (i.e., the term “fluidization”) but at much higher temperatures than a liquid can reach. These liquid-like properties are the secret to fluidized bath technology, providing fast heat-up of immersed objects.

The aluminum oxide media provided by Accurate Thermal Systems is inert and highly safe to use. The particle size of our aluminum oxide is 120 grit, and once an item is removed from the fluidized bath, the aluminum oxide media will either fall off or can be easily removed with compressed air. A fluidized bath is not a grit or media sandblaster. Aluminum oxide is non-abrasive to immersed objects. Organic material is thermally burned off through the gentle bubbling action of fluidization.

Why Choose Our Fluidized Temperature Baths?

A fluidized bath’s liquid-like properties provide fast heat transfer to immersed objects for immediate heating and thermal performance desired from a heat source. Large working volume and heat capacity are ideal for heating large and small objects. Fluidized temperature baths do not require consumables or chemicals to operate, are safer than salt baths, and provide superior temperature stability and uniformity versus ovens.
