The FFB-8 is a precision fluidized
bath, with exceptional temperature
stability and uniformity, which make
them the ideal choice for critical
temperature sensor calibration and
heat treatment processes. FFB-8
fluidized (sand) bath has become
the market standard for carrying out
shape setting (heat treatment
processing) of metals including
Nitinol and platinum for medical
device manufacturing. This unit is
suitable for many other applications,
including thermal testing of sensitive
components such as semiconductor
devices, wire products, delicate
transducers and may also be used
as a constant temperature
environment for chemical reactions.
Because the fluidized bed is a fine,
dry powder, it does not have surface
tension effects of liquid baths and
will not wet any immersed
components. The electrical
insulating properties of the alumina
used in the FFB-8 are not affected
by fluidization making.
* The dead bed mode of operation is entered
by shutting off air and power to the unit.
The system reaches a state of thermal
equilibrium after the bath media collapses
and stability is better than ±0.010°C for a
period of 3 to 6 minutes. This allows for
precise comparison calibration of
temperature sensors in the bath.
