CAUTION: OVENS PROCESSING COMBUSTIBLE
MATERIAL ARE REQUIRED BY NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 86 TO
HAVE A FIRE SUPPRESSION SYSTEM. IF FLAMMABLE SOLVENTS OR VAPORS ARE PRESENT
IN AN OVEN, OSHA REQUIRES CONFORMANCE WITH NFPA 86 WHICH DEFINES OVENS FOR THESE
APPLICATIONS AS CLASS A OVENS. A POWERED FORCED EXHAUSTER AND OTHER NONSTANDARD
SAFETY EQUIPMENT MUST BE ADDED. SEE BULLETIN TC-940

*All Models—Control panel overhang 9" right side. Blower motor overhang 17" (26" HC Series); H Series right side, V Series rear.
Electric model HX, HB, HY, HC—Heater terminal overhang 5" rear and left side. Gas Model—Burner overhang 11"; H Series left side, V Series right side.
†Accuracy as percent of controller span. Uniformity at 100°F below maximum temperature. Rise Time in minutes to 100°F below maximum
temperature. Tests run with empty oven and minimum exhaust. Performance will vary
with load and application. See Bulletin TC-920
for additional details.
Inner and outer door gasket; inner gasket seals directly against door plug, outer
gasket against oven face. Two (2) reinforced 200 lbs uniformly distributed load
capacity, 304 stainless steel expanded metal shelves; shelf support channels on
3" centers (6" on HC Models).
304 stainless steel interior and Trilite Green enamel painted aluminized steel
exterior.
Electric Models
Each features completely wired, side access UL
listed control panel enclosing terminals for incoming power, temperature controllers,
push buttons and pilot lights. Motor starter and heating element contactors
electrically interlocked to shut off heaters if power to blower is interrupted
and to permit operation of blower without heat for cooling. Incoloy sheathed
tubular heating elements. The 1250°F models have a heat chamber high limit
controller. Exhaust outlet 4" diameter.
Gas Models
—1,000 BTU natural gas at 6" water column pressure, 1" NPT inlet
—Other gas characteristics available
Control panel as detailed above and safety devices as listed on the front of
this bulletin. Automatic pre-ignition purge period and push button electric ignition
contributes to ease of operation. Modulating gas burner is protected with electronic
flame
safety relay.
H SERIES Horizontal Air Flow
These electric or gas-fired models come in five sizes. They feature full horizontal
air flow for shelf processing at temperatures to 1250°F. Commonly used
where work is shelf loaded and least restriction to free air passage is in the
horizontal
direction.
HA Series – 4.6 cubic feet, holds 6 shelves
HX Series – 11.4 cubic feet, holds 8 shelves
HB Series – 21.7 cubic feet, holds 12 shelves
HY Series – 31.8 cubic feet, holds 12 shelves
HC Series – 72.3 cubic feet, holds 8 shelves
HC Series High Temperature Cabinet Ovens have the heat chamber above the work
space.
V SERIES Vertical Air Flow
These electric or gas-fired models come in two sizes. They feature full vertical
air flow for processing at temperatures to 1250°F. Used where least
restriction to free air passage is in the vertical direction. Heated air is
supplied at the bottom of the work space and sweeps upward through the work
load. Ideal for hanging long parts or applications requiring heated air
to pass both around the outside and through the middle of parts such as open ended cylinders.
VA Series – 14.9 cubic feet, holds 12 shelves
VB Series – 28.6 cubic feet, holds 16 shelves
Due to vertical air flow, a large number of shelves or dense shelf loading will
restrict air flow and may adversely affect oven operation.

H Series Heated air is blown sideways between shelves and across parts
V Series Heated air is provided at the bottom and pulled upward through shelves and load.
