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 AND CONSULT FACTORY.

*All Models—Control panel extends 13" above. Blower overhang 10" rear. Electric Models—Heater terminal box overhang 4" right side. Gas Model—Burner overhang 11" right side.

†Accuracy as percent of controller span. Uniformity at 50°F below maximum temperature. Rise Time in minutes to 50°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.

STANDARD EQUIPMENT  Back to Top

Two (2) reinforced 100 lbs uniformly distributed load capacity nickel plated wire shelves. Nine (9) pair shelf support channels on 6" centers; first shelf 8" above factory floor. Fully insulated 2" thick floor reinforced for 500 lbs distributed loading.
Aluminized steel interior and Trilite Green enamel painted aluminized steel exterior.

Electric Models
Each features completely wired, top 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. Alloy wire heating elements. 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.

CAH AND CBH SERIES
Horizontal Air Flow
These electric or gas models come in two sizes. They feature full horizontal air flow with adjustable patented opposed louvers on full coverage supply and return duct work. Commonly used where work is shelf loaded and least restriction to free air passage is in the horizontal direction.

CAV AND CBV SERIES
Vertical Air Flow
These electric or gas models come in two sizes. They feature vertical air flow for processing at temperatures to 550°F.

Used where least restriction to free air passage is in the vertical direction. Heated air is supplied at each side of the work space and sweeps upward through the work load. Ideal for hanging long parts or placing large objects directly on the oven floor.

Other specifications identical to CAH and CBH Series above.

Circulation Diagrams ( Front View )
CAH and CBH Series Heated air is blown sideways between shelves and across parts.		CAV and CBV Series Heated air is provided from each side and pulled upward around the load.
