LOW COST ELECTRIC AND GAS OVENS FOR CONVENIENT TRUCK LOADING
Hard working ovens designed for
baking, drying, preheating or any other application where a dependable source
of heated air to 500°F is required. Complete with temperature controllers
that offer the latest in heat-sensing technology and built-in floor level guide
tracks that make truck loading easy.
Standard Truck 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 NON-STANDARD SAFETY EQUIPMENT MUST BE ADDED. SEE BULLETIN TC-940

†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.
All Models
— 208 volts, 3-phase, 60 Hz
— 230 volts, 3-phase, 60 Hz
— 460 volts, 3-phase, 60 Hz
— Other electrical characteristics available
Insulated floor with truck
wheel guide tracks. Aluminized 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. Alloy wire heating

TA AND TB SERIES Combination Air Flow
These electric or gas models come in two sizes. They feature combination vertical
and horizontal air flow for truck processing of various size parts at temperatures
to 500°F.
TA Series
Size 36" x 36" x 60" high provides 45 cubic feet of work space. Truck tracks
2" wide, 24" center to center. Optional companion truck holds twelve 30" x 30"
shelves on 4" centers.
TB Series
Size 48" x 48" x 60" high provides 80 cubic feet of work space. Truck tracks
2" wide, 36" center to center. Optional companion truck holds twelve 42" x 42"
shelves on 4" centers.
TAH AND TBH SERIES Horizontal Air Flow
Similar to TA and TB Series, these electric or gas models feature full horizontal
air flow with adjustable patented opposed louvers on full coverage supply and
return duct work. Used when vertical air flow through the load is restricted.
Ideal for processing flat sheets, pans of parts or when shelves are densely packed.
Circulation Diagrams
