Welded
Construction
Outside
walls are made from 12 and 14-gauge steel, reinforced and
lined with insulation material pressed into welded studs and
retained with heavy-duty expanded panels.
Total Insulation
Oven is
insulated with 1200 ºF rated mineral fiber blanket 4" thick on
sidewalls and roof. Oven floor is a 2300 ºF poured castable
refractory, providing a hard durable surface for cleaning and
service.
No-Sag Doors
Heavy-duty
insulated doors are furnished with cam lock door hardware top
and bottom on single door models, top, bottom, and center on
double door models. The cam lock arrangement is essential for
sealing the doors airtight during the heating cycle. Doors
include high temperature gaskets around door perimeter and at
closures.
Explosion Relief Panel
Explosion
relief panels allow excess pressure on inside of oven to
equalize with outside pressures without danger to equipment,
operators, or facilities. Hinged explosion relief panels are
designed into the roof of the oven that allows adequate
pressure relief by swinging open and then closing immediately
by gravity.
FM
Option
The following additional combustion control items are included
to meet Factory Mutual Insurance Association requirements:
* FM burners,
* Automatic gas solenoid valve
* Flame safeguard control (non-recycle)
* Ignition transformer.

Control Panel
NEMA-12 rated control panel, complete with door hardware.
Mounted inside the cabinet on a removable panel insert will be
a 15 amp circuit breaker, control relays, interlocks, timer
and terminal strips. Mounted on the control panel door will be
pushbuttons, indicating lights, programmable controller/timer,
and afterburner temperature read-out. The control panel is
factory pre-wired.
Safety
Controls
Standard system includes state-of-the-art micro-based controls
used to control temperature, water suppression, and cycle
time. A dual-element temperature-sensing unit, placed in the
oven chamber, senses temperature and provides a digital
read-out on the corresponding instrument mounted in the
control panel door. This device will sense excessive
temperatures based upon a safe operating set point. Should
excess heat be generated by the coatings, water is
automatically injected into the oven to absorb this heat and
reduce the oven temperature. Also includes a state-of-the-art
dual-element temperature-sensing unit placed in the
afterburner chamber.
IRI
Option
Industrial Risk Insurers require two (2) safety add-ons in
addition to the FM package.
HI/LOW
Fire Afterburner Option
This
option addresses EPA concerns of the afterburner being at
temperature prior to release of smoke.
