ST Vacuum Oven
The Model
ST is our standard hot-wall type vacuum oven. We utilize
long wavelength infrared to heat the vacuum vessel from the
outside, absorbed heat is then reradiated to the product.
Both sides, top, and bottom walls are fully heated in order
to maximize heat distribution and uniformity. The Model ST
has several temperature capabilities
 depending
on configuration:
Thermal
loading of the ovens operating environment has been
addressed by incorporating a top mounted draft inducer for
the removal of convective heat losses produced by the
heaters, maintaining the exterior at temperatures below 122°
F (50°C). This draft inducer also assists the natural
cooling effect of the vessel once the heaters have been
shutdown.
 Model
ST’s are offered in three standard interior sizes which are
constructed from a brushed finish 304L
Stainless Steel .250-in
plate, fully passivated, with other material grades
available as options. Our unique gusseting and welding
techniques
give our vessels superior strength and integrity under high
vacuum and temperatures. All of our vessels are helium leak
tested to 5.0 x10-7
Torr. Higher vacuum tests
are
available upon request. Our standard exteriors are
constructed from heavy gauge cold roll mild steel and powder
coated, a customer selected
color, for a long durable finish.
 Our
control system is unsurpassed in the industry, offering
fully digital programmable time temperature and vacuum
control. We also offer an optional a 6.00-in color
touch-screen and PLC control fully automating and
simplifying programming and operator interface.
We also
have the most complete line of options and accessories for
your system, and or process, such as moisture and oxygen
analyzers, sensor and process feed-throughs, shelves and
fixtures, data loggers, inert gas preheating, high vacuum
pumping, vessel cooling and blower circulation.
Control
type, pumps, traps and other options and accessories are all
configurable on the Model ST.
