The Centorr Series M60 Multi-Purpose Front Access Furnace is part of a
long-standing tradition of quality and dependability in high temperature,
controlled atmosphere heating technology.
The M60's cylindrical hot zone is resistance heated (up to 2000°C),
and is insulated from the cold wall by a multi-layer configuration of metallic
radiation shields or rigid graphite insulation.
Access to the hot zone for loading and unloading, as well as for routine
maintenance and inspection, is through the full-opening front door. Clamps
are provided for operation to slightly positive pressures.
The inside of the furnace chamber conforms to the best high-vacuum practices,
with particular attention given to surface finish and choice of materials.
The design and construction of high quality vacuum furnaces calls for minimizing
component surface area and potential leaks; thus, you won't find inferior materials,
or internal coolant connections in a Centorr Vacuum Industries' M60 furnace.
Visual observation of the specimen is provided by a sight port equipped with the
Centorr Vacuum Industries' designed rotatable viewing glass. Ports are also
provided for inert gas inlet, thermocouples, gauges, and other pertinent
instrumentation.
All instrumentation is carefully positioned in an attractive console for optimal
monitoring and control. Furnace temperature is controlled by a closed-loop circuit
between the temperature sensor (thermocouple, power transducer, or optical
pyrometer), the control instrument, and the power supply. The whole furnace
system is protected by a water-flow interlock that shuts down the hot zone if
cooling water flow is reduced or closed off. All components are readily accessible
for inspection and maintenance.
These furnace systems are ready to operate as soon as soon as connections are made
to the proper utilities and a few start-up tests are performed. Each Centorr Vacuum
Industries' M60 furnace is completely assembled and thoroughly tested before it
is shipped.
Specifications
Hot zone size: 3" diameter by 8" high; or 4" diameter by 8"
high
Heating Element: available in tungsten, tantalum, molybdenum, Kanthal or graphite
Heat shields: multi-layered metallic or rigidized graphite
Power feed-throughs: water-cooled copper
Furnace access: through full-opening front door; hinged to pull out and swing free
so Viton O-ring will not scuff. Location and locking pins assure door remains open
and away from work area; clamps allow for operation to 2 psig.
Viewing port: .250" (6.4mm) diameter gas-ported rotatable sight window located
at the front and center of the heat zone.
Chamber: 304L stainless steel, water jacketed. Outer shell temperature maintained
at 150°F (65.5°C) maximum.
Power supply: Silicon controlled rectifier (SCR) power pack and phasing system
for continuously modulating power input. All power supply components pre-wired and
housed in an attractive floor standing cabinet.
Evacuation port: 4" port on rear cover
Mounting: furnace chamber mounted on a floor stand.
Utility Requirements
Electrical: kVA at user's primary voltage; single or three phase;
50 or 60 hertz.
Water: 7 gpm @ 30-50psig (26.61/min. @ 2.11-3.52 kgs/cm2); 70°F
(21°C) maximum inlet temperature; pH should be 7.0-7.5; conductivity should be
300-400 micro mho.
Compressed air: 60-90 psig (4.20-6.31 kgs/cm2), filtered and
lubricated (to operate electro-pneumatic valves on automatic and semi-automatic
vacuum systems).
Floor space: 3' x 4' (.92m x 1.22m) without pumping system; 4' x 6'
(1.22m x 1.83m) with pumping system.
Weight: approximately 1500 lbs. (675 kilograms).
Optional Equipment
Vacuum System
For operation in 10-5 to 10-7 torr vacuum range, an variety of
high-vacuum pumps are available, including diffusion pumps, turbo-molecular pumps,
and cryogenic pumping systems; oil-free pumping technology is also available. Each
vacuum system comes complete with necessary valves, vacuum instrumentation, flanging,
manifolding, and traps, all properly sized to evacuate the M60 chamber quickly. All
vacuum systems can be wired for fully automatic, semi-automatic, or manual operation.
Process Gas System
The gas system for the M60 consists of a vacuum-tight inlet valve, a relief valve,
a Bourdon-type pressure/vacuum gauge, and necessary manifolding.
Evacuation System
For operation in the 10-50 micron range prior to backfilling with an inert gas,
the Centorr Vacuum Industries' evacuation system features a mechanical pump, along
with all necessary valves, manifolding, and instrumentation. Oil-free pumping
technology is available in this pressure range, too.
Temperature Control Instrumentation
Centorr Vacuum Industries can supply instrumentation from the simplest manual power
control to the most elaborate automatic closed-loop control. Thermocouples, power
transducers, and optical pyrometers are available for sensing; any of these can be
combined with indicator-controllers, recorders, and/or programmers for precision
temperature control. Microprocessor-based programmers are also available.
