Front-to-back horizontal air
flow accommodates virtually any oven loading without restricting air passage.
Work can be shelf loaded or placed directly on the optional reinforced work space
bottom. Four sizes from 8 to 36 cubic feet. Top mounted control panel minimizes
floor space required. Designed for baking, drying, preheating or any other application
where a dependable source of heated air up to 850°F is required.
Standard Universal Ovens from Grieve meet the requirements of National Fire Protection Association Standard 86, Industrial Risk Insurers, Factory Mutual and OSHA standards. For some applications, such as those involving flammable solvents or hazardous locations, the above organizations require additional safety devices.

SPECIFICATIONS Back
to Top 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.
†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.
