Optimal Uniformity, Fast Recovery Time

Their microprocessor controller achieves precise environmental control and maintains stable temperatures for optimal results. The unique turbo blower system creates a true one-pass circulation pattern that provides both exceptional temperature uniformity (± 1.8°C @ 100°C) and rapid heat recovery, without temperature overshoot.

Uniformity is enhanced by a horizontal airflow system, which offers a level of performance usually found only in more expensive ovens. Horizontal air flow creates optimum circulation when the oven shelves are fully loaded. Heated air is directed into the duct space and flows through horizontal slots and across the shelves. A slide-operated vent allows the user to adjust fresh air ventilation. This permits adjustment from continuous fresh air intake to closed recirculation.

Select between large-capacity, 28.0 cubic foot (0.8 m³) and medium-capacity, 14.0 cubic foot (0.4 m³) models. Both incorporate safety overtemperature protection, which operates independent from the microprocessor and controls the heating function if the main temperature set point is exceeded. Other standard features include a P.I.D. Temperature control and an electronic digital timer, with large, easy-to-read LED display that indicates both temperature and time parameters.
