RECIRCULATION FOR UNIFORMITY +/-10F
An alloy fan is mounted in the top. The motor is 1/6 H.P.
STAINLESS STEEL INTERIOR
The entire interior is made of stainless steel for heat and corrosion
resistance. The liner is designed to expand and contract with the heat.
BENCH MOUNTED CASE CONSTRUCTION
The oven case is constructed of 10, 14 and 16 gauge steel with an integrated
bench stand. The case is primed with 800F silicone paint and finished in machine enamel.
SEVEN INCHES OF INSULATION
There is 1 of 2300F ceramic fiber insulation backed up with 6 of
mineral wool. All insulation is sandwiched between the interior liner and exterior of the
oven. No asbestos is used.
The elements are incoloy sheathed elements which are rated for 1600F. They
are easily replaced.
The door is pivoted on the left. A woven fiberglass tadpole gasket and
adjustable latch seal the door tightly.
DIGITAL PID CONTROL AND HIGH LIMIT SYSTEM
The standard control is a Honeywell UDC 2000 digital PID 3 mode tuning
control. All fuses, transformers, contactors, and controls are located in a NEMA 1 panel
mounted on the side. Panel includes a hinged door and generous internal spacing. Quiet,
long life mercury power contactors are standard. The thermocouples are Type K. The control
voltage is transformed to 120 volts. Control and power circuits are branch fused. Limit
switch turns off power if the door is opened. A NEMA 13 lighted On/Off switch is included.
A Honeywell UDC 2000 digital high limit back up control with manual reset, back up
contactors and separate thermocouple is included as standard. Customer must connect fused
power supply to single point on panel.
TESTING AND INSTRUCTIONS
The oven is power tested to insure proper watt ratings. A complete
instruction manual includes easy start up instructions, theory of operation, maintenance
instructions, parts list, and a detailed trouble shooting guide. A ladder logic diagram
and panel layout are prepared on CAD for easy readability.
The oven is warranted for one year except for elements and thermocouples
(warranted for 6 months.)
- JIC CONTROL OPTION: This includes a NEMA 12 control cabinet, all
oil tight switches and a panel mounted fused disconnect switch.
- INERT ATMOSPHERE BLANKETING: A flowmeter/regulator combination
unit is provided which fits onto a compressed gas bottle. Nitrogen or argon can blanket
the inside of the oven, although there will be some leakage around the fan shaft and door
seal. Usually 5 to 10 volume changes per hour are required. If a program control is
ordered an event switch can be used to shut off gas with an optional solenoid.
- SCR POWER CONTROL: This provides longer element life and more
even heating. It also allows the oven to be used to 1400F.
- SPRING LOADED EXPLOSION RELIEVING LATCH
- MANUAL OR POWERED VENTURI VENT: A manual or air powered venturi
can be provided for venting the oven. Optional safety package for solvent use.
- SHELVES AND SPECIAL HEARTHS: Perforated stainless steel shelves
- ANGLE IRON STAND: Standard hearth height with optional stand is
32 from floor. Includes leveling bolts.
