| Vacuum ovens are used for a wide variety
of vacuum drying, curing, and moisture content testing. common
applications include drying heat sensitive samples, moisture
determination, and drying samples under a controlled atmosphere. SHELLAB
vacuum ovens are specifically designed for unparalleled performance when
utilized for these, and other, applications. |
 |
Since there is no air in the vacuum chamber, heat is transferred from the
heating elements to the interior chamber wall, then to the shelves, and finally
to the samples. SHELLAB vacuum ovens maximize conductive heat techniques. To
minimize conductivity resistance, ALUMINUM shelves are provided with all SHELLAB
vacuum ovens. The oven chambers are wrapped in high temperature insulation which
aids overall performance and promotes energy efficiency.
Sheldon offers both standard ANALOG vacuum ovens with mechanical thermostats
and a range of high-performance, MICROPROCESSOR CONTROLLED models. Both ranges
include unique design features which enhance the overall performance of the
ovens. These features include durable construction with corrosion resistant
stainless steel chambers, true vacuum valves, cross-flow ventilation through the
oven chamber, and interchangeable door gaskets for application specific use.
Independent, resettable circuit breakers prevent any electrical overload.
Analog Models for Accuracy and
Economy

The Models 1410 and 1430 feature
hydraulic thermostats and corrosion resistant stainless steel interiors.
A 13mm thick tempered glass observation window resists breakage under
vacuum and permits easy viewing of the chamber interior. Glass viewing
windows are "spring mounted" which allows the door to close
squarely, thus ensuring a tight seal around the oven door. Furthermore,
the door gasket has a beaded edge which also ensures vacuum integrity. |

| In addition to the standard ANALOG
models, Sheldon also offers the Models 1410D, 1430D, and 1450D
DIGITAL vacuum ovens. Our PID (Proportional Intergral Differential)
controller delivers precise temperature stability and uniformity. A
touchpad control panel provides easy parameter setup and even
temperature calibration. Both setpoint and actual chamber temperatures
are digitally displayed. |
 |
The SHELLAB DIGITAL vacuum ovens feature all stainless steel construction; both
chamber interior and oven exterior. All models have two doors; the inner door
featuring a "spring mounted", tempered glass viewing window. Closing
the outer stainless steel door serves to greatly diminish any heat dissipation
through the glass viewing window. All doors are secured with a positive door
latch.

The standard gasket supplied with all models is made of highly resistant
SILICONE rubber. Also available as optional accessories are application specific
gaskets. The BUNA-N gasket is available for solvent applications and is limited
to a maximum temperature of 160 Deg. C. The VITON-B gasket is available for
application involving acids.
 |
All SHELLAB vacuum ovens feature a unique
cross-flow ventilation design to ensure superior performance. The vacuum
port is located inside the chamber on the top, left side, while the vent
port is located on the bottom right side of the chamber. Therefore,
during vacuum operation, heavy particles or condensation from the oven
interior are not pulled into the vacuum pump. More importantly,
Nitrogen, or other inert gas, is forced across the greatest distance
inside the oven chamber, passing over your samples, and purging the
chamber. Corrosion resistant stainless steel tubing is used for the gas
purge piping system. |

1495D Vaccuum Oven/Station
Vacuum ovens are used for a wide variety of vacuum drying, curing, and
moisture content testing. Common applications include drying heat
sensitive samples, moisture determination, and drying samples under a
controlled atmosphere. SHELLAB vacuum ovens are specifically designed
for unparalleled performance when utilized for these, and other,
applications.
The model 1495D is a general-purpose vacuum oven specially designed for
professional and industrial use. The most salient feature of this oven
is its size: 9 cubic feet (255 Litres). The oven is secured to a
ruggedly constructed mobile stand, thus creating a vacuum station. The
stand is designed for mounting a vacuum pump at the base. Although the
oven is not supplied with a vacuum pump, all vacuum plumbing and KF25
connections are provided. Stainless steel is used for all vacuum tubing
and connections. |
A digital vacuum gauge, mounted in the control panel, shows the chamber vacuum
level in measurements of Torr and m/Torr. Although this gauge has the capacity
to act as a controller, in this application it functions only as a gauge with
display. The display range is 760 torr down to 0 mil torr.
The microprocessor based main temperature controller offers multiple ramp and
soak capabilities. The WATLOW 981 programmable controller is capable of storing
and running up to 24 steps of ramp and soak temperature profiles. A secondary,
and completely independent, High Limit controller provides overtemperature
safety protection. All controls are easily adjustable at the control panel.
Since there is no air in the vacuum chamber, heat is transferred from the
heating elements to the interior chamber wall, then to the shelves, and finally
to the samples. To minimize conductivity resistance, Aluminum shelves are
provided. The oven chamber is wrapped in high temperature insulation, which aids
overall performance and promotes energy efficiency. All stainless steel
construction, true vacuum valves, and cross-flow ventilation through the oven
chamber aid overall performance.

Ovens - Microprocessor Controlled |
| Simulate the same environments you find
when flying at high altitudes. Without the flying part. We were
thinking. Always thinking. Always trying to find new ways to give you
top-of-the-line products. We have a history of firsts in the industry.
But our heads aren't in the past; they're in the future, thinking up
other firsts to create. That's how we keep temperature and pressure
constant. That's how our products endure heavy use. And that's how we
plan to stayŃforever supplying products of constant thinking. With that
in mind, here are specs on our digital vacuum ovens: |
 |
Cool outer surface - A result of our double plenum design, which exceeds
CE safety requirements.
Introduced gas saturates chamber uniformly - Our unique cross-flow
ventilation forces inert gas to fill the entire chamber, as seen to the right.
Maintains precise temperature - Our PID controller combined with
appropriately sized heating elements maintains precise temperature stability
with no overshoot.
Won't over heat - Our independent over-temperature safety control
maintains chamber temperature should the main control malfunction.
A product of constant thinking for constant use - Durable construction
with seamless welds and strong bracing.
All of our vacuum ovens are built with a stainless steel chamber for
exceptional durability. We use true vacuum valves built of brass with 3/8"
orifices to withstand heavy use and minimize draw-down time. The doors have
positive latch handles with spring loaded glass to facilitate a good vacuum seal
without leaks. A selection of gaskets (for specific applications) and a small
bench top footprint increase the versatility of our ovens. And they all come
with a 12-month warranty. We were the first to bring square vacuum ovens to the
industry and we continue to offer innovative, top-of-the-line vacuum ovens.
