Overview of Techne Fluidized sand baths

     Fluidized baths offer an open work area with the potential for a wide range of  applications where a stable temperature environment is required. They use a media that never needs replacing and doesn't evaporate, are safe to operate and thus a logical choice over molten salt baths, high temperature oil baths and ovens and furnaces.

Applications for Fluidized baths (a few of the many):
bullet

Verification & calibration of temperature sensors, devices and systems (Lab Series, FB08)

bullet

Shape setting of various metals including Nitinol for Medical Stents (FB08 & Industrial range)

bullet

Cleaning of tooling (breaker plates, screws, heads, nozzle) used in plastics manufacturing (IFB series)

bullet

Tempering, annealing & Nitriding of various metals (all models)

bullet

Reactive chemical analysis including distillation, heating of reactors (FB08 & Industrial range)

bullet

General heat treatment applications up to 600ºC/1112ºF (FB08 & Industrial range)

bullet

Thermal analysis of devices, components and materials (all models)

From 10.2" x 12" to 10.2" x 26.0" (diameter x depth) ±1.0 up to 600ºC Cleaning of tooling and parts in Plastics manufacturing.
Heating of reactors, chemical reactive analysis, endothermic and exothermic reactions. Large working area.
Precision FB08 Range FB08 Precision Fluidized bath 50ºC to 700ºC
(122ºF to 1292ºF)
6.5" x 15.0" (diameter x depth) ±0.08ºC full range normal mode

±0.008ºC full range dead bed mode

PRT, SPRT, RTD & Thermocouple comparison calibrations. Shape setting of Nitinol stents and other medical device heat treating.

 

Comparison chart of heat sources - Why choose a Fluidized bath?
  Fluidized bath Molten salt bath Ovens & Furnaces Hi-Temperature
Oil & Ultra-sonic baths
Stability & uniformity good fair fair good
Safety good poor
 (highly volatile)
good poor
 (fumes, odors, splashing & hazardous fluids)
Efficiency & quench recovery good good poor
(heat is lost when opening doors)
good
Setup & ongoing costs good fair
 (must add salt as it's lost on items put in bath)
good poor
(must add fluid as it's lost in use & evaporation. Fume exhaust required)
Notes: Non-abrasive to product immersed in the bath must clean off product after being placed in bath Slow heat transfer must clean off product after being placed in baths - environmental impact of used fluids
