generaL DeSCrIptIOn

The SBL-2D bath inner is a cylindrical stainless steel vessel of welded construction and inside diameter
230 mm (9"). This vessel is suspended in, but thermally insulated from, an outer mild steel cylindrical
container. The porous plate is made of either sintered or woven mesh stainless steel and is mounted across
the vessel between compression flanges. Bath insulation is provided by fibreglass but some circulation of
air is provided to prevent the outer container from getting too hot.
Each of these fluidised baths have 1kW Inconel sheathed electric heating elements mounted just above
the porous plate. The SBL-2D has four heaters. The air control valve is mounted at the right hand side
of the bath. A pneumatically operated safety switch is fitted which switches off the heating current in
the event of failure of the air supply.
Temperature control is achieved by a manually operated energy regulator. This may be by-passed by setting
it to maximum and fitting an externally connected controller, the Techne TC-8D. On the SBL-2D switches
are fitted for the selection of either 1kW or 2kW or 3kW heat input but only the initial 1kW is controlled
by the energy regulator. A switch is fitted for the selection of the fourth boost heater, this heater is not
controlled by the energy regulator.
Each heater has its own neon light indicator to show when it is working.
The air supply must be from a filtered and regulated air line or alternatively a Techne air pump, F119D
for 240V or F119P for 120V, may be used. The air pump includes a safety valve and special filters and is
driven by 1/4 HP electric motor.
