Description

Rugged ovens designed for baking, drying, preheating or any other application requiring a reliable source of heated air at 550°F.

They are equipped with temperature controllers featuring the latest heat sensing technology and integrated floor level guide rails for easy truck loading.

Standard Features
CONTROL PANEL LISTED UL Grieve's standard truck ovens meet the requirements of the National Fire Protection Association Standard 86, Industrial Risk Insurers, Factory Mutual and OSHA standards. For certain applications, such as those involving flammable solvents or hazardous locations, the above organizations require additional safety features. Control Digital temperature controller, based on a microprocessor, operated by a thermocouple and indicating the temperature. Modulating burner on gas ovens Motor control buttons and heat on/off switch LED indicator lights Safety equipment - Electric oven Adjustable, thermocouple-operated, manual reset overtemperature lockout. Separate heater control switches Recirculation fan air flow safety switch Safety equipment - Gas oven Adjustable, thermocouple-operated, manual reset overtemperature lockout. Electronic flame protection 325 CFM forced air vent for combustion exhaust Exhaust air flow safety switch Recirculation fan air flow safety switch Purge timer High gas pressure switch Low gas pressure switch Two pilot safety shut-off valves with leak test stations Two main safety shut-off valves with leak test stations Valve position indicator on main safety shut-off valves Construction Choice of airflow patterns specifically for truck processing Aluminized steel interior Aluminized steel exterior with enamel finish Brushed stainless steel control panel face Explosion-proof vent latches 6" of 10 lb/ft3 industrial rock wool insulation Built-in baffles prevent radiant heat Silicone rubber door seal Insulated floor with truck rails Adjustable fresh air intake and exhaust louvers High pressure recirculation fan One year limited warranty Each oven is fully assembled and individually tested at the factory

Specifications
Caution: Furnaces handling combustible materials must be equipped with a fire suppression system in accordance with National Fire Protection Association Standard 86. If flammable solvents or vapors are present in an oven, OSHA requires compliance with NFPA 86, which defines ovens for these applications as Class a ovens. A forced draft system and other non-standard safety equipment must be added.

* All Models — Blower motor overhang 10" rear. Control panel overhang 9" right side. Gas Models — Burner overhang 15" 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.

Standard equipment
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 rails. Aluminized steel interior and aluminized steel exterior painted in Trilite green enamel.
Electric models
Each unit has a fully wired, side access, UL listed control panel with terminals for power supply, temperature controls, push buttons and pilot lights. The motor starter and heater contactors are electrically interlocked to turn off the heaters if the fan power is interrupted and to allow the fan to operate without heat for cooling. Alloy wire heating elements. 4" diameter exhaust outlet.
Gas models
1000 BTU natural gas at 6" water column pressure, 1" NPT inlet Other gas characteristics available Control panel as detailed above and safety features as listed on the front of this bulletin. Automatic pre-ignition purge period and push-button electric ignition contribute to ease of operation. The modulating gas burner is protected by an electronic flame safety relay.
TA, TB AND TC SERIES
Airflow combination	These electric or gas models come in two sizes. They feature a combination of vertical and horizontal airflow for truck processing of different sized parts at temperatures up to 550°F.
TA Series
The 36" x 36" x 60" high dimensions provide 45 cubic feet of work space. Cart rails are 2" wide, 24" center to center. Optional add-on cart holds twelve 30" x 30" shelves at 4" intervals.
TB Series
The 48" x 48" x 60" high dimensions provide 80 cubic feet of work space. Cart rails are 2" wide, 36" center to center. Optional add-on cart holds twelve 42" x 42" shelves, spaced 4" apart.
TC Series
The 60" x 60" x 60" high dimensions provide 125 cubic feet of work space. Cart rails are 2" wide, 48" center to center. Optional add-on cart holds twelve 54" x 54" shelves at 4" intervals.
TAH, TBH AND TCH SERIES
Horizontal Airflow	Similar to the TA, TB and TC series, these electric or gas models feature full horizontal airflow with adjustable opposed louvers on full surface supply and return ducts. They are used when vertical airflow through the load is limited. Ideal for processing flat sheets, coin trays, or when shelves are densely packed.
