DS-70EX Explosion-Proof Forced-Air Drying Oven, 81 L and 1.5 kW (CAT#: STEM-BC-3680-ZJF)

The DS-70EX is an 81 L explosion-proof oven for controlled drying and thermal processing. It is intended for materials or workplaces involving flammable and explosive gases. The control system combines flameproof and intrinsically safe protection methods. Passive operating switches avoid generating electrical sparks during adjustment. The PID temperature controller presents operating data clearly on the LCD. Internal forced-air circulation accelerates heat transfer and improves chamber temperature uniformity. A reinforced 304 stainless-steel interior resists corrosion and simplifies cleaning. Overtemperature cutoff, alarms, parameter memory, and timed operation support secure unattended processing.
