DS-640EX Explosion-Proof Forced-Air Drying Oven, 640 L and 6 kW (CAT#: STEM-BC-3684-ZJF)

The DS-640EX is a large-volume forced-air drying oven designed for hazardous processing environments. It provides a 640 L chamber for drying, baking, curing, and controlled heat treatment. The composite electrical protection system combines flameproof and intrinsically safe technologies. Its sensor is isolated through a safety barrier, while passive switches prevent operating sparks. A microcomputer PID controller maintains stable temperature and displays all essential process information. Forced heated-air circulation improves drying speed and chamber uniformity. The reinforced stainless-steel interior, thick insulation, adjustable shelves, and wheeled structure support heavy-duty operation. Automatic self-checking, temperature correction, timing, memory, alarms, and heating cutoff provide layered safety protection.
