Despatch Electric Ovens


All Despatch laboratory ovens feature digital microprocessor controllers, open coil heater elements, and a five year warranty.


Double-wall construction with glass fiber insulation and silicone door gaskets minimize heat loss. Exterior surfaces have scratch-resistant baked enamel coating and stainless steel interiors. Shelf location can be repositioned every 2in (52mm). Two shelves are included.

Standard DOL series forced-convection ovens have single setpoint digital proportioning controller and rocker switches for power and heat. Maximum temperature is 400°F (204°C). Models with capacity 6.9ft³ (200L) and larger are supplied with two chamber doors. Forced air circulation from top mounted fan and side plenums allow rapid and effective heat distribution, permitting higher-density work loads. Chamber temperature uniformity is ±3° at 150°C. Optional DOBA-2 Count-Down Timer for Standard DOL series shuts down heater at the end of each cycle time. Count-Down Timer range is 99.9 hours; range can be changed to 999, 9.99, or .999 hours or minutes.

Deluxe DOC ovens have superior thermal uniformity and a forced-air convection system with an adjustable damper. They also feature the exclusive Despatch Protocol 3™ microprocessor controller system. This controller has self-diagnostic and calibrating capabilities, two levels of password security to protect program parameters and a recovery system for controlled responses to power failures. Oven can be set to operate at a single setpoint temperature, in timed cycles, or up to 255 total ramp and soak profile segments in up to 64 programs. Additional options allow control of multiple units from a remote PC. Large LED temperature display and 32-character LCD display of oven status and setpoints are easy to read and simplify programming. Control stability after calibration is ±0.5°C at 25°C. Oven uniformity is ±1° at 100°C.

Stands and Extra Shelves are available for bench ovens. Matching enameled-steel 22in (559mm) high stands allow placement of ovens on floor instead of bench tops. Stands have a support frame with one open shelf. Stacking Hardware is available to stack two similar ovens. Two standard shelves are included with each oven; heavy-duty shelves are standard on DOL Models. Inquire for optional heavy-duty, reinforced shelves for other models. Ovens will operate on 50Hz or 60Hz power supply. Some units are available in either 120V or 240V. 240V ovens will operate on a 208V electrical supply with approximately 25% reduction in heating output. Specify the voltage required when ordering.
