DGF-4S Double-Door Forced-Air Drying Oven, 640 L and 300°C (CAT#: STEM-BC-3544-ZJF)

The DGF-4S is a large-capacity forced-air drying oven for laboratory and industrial thermal processing. Heated air is circulated through the chamber by dual fans and dual air ducts. This forced circulation promotes uniform heat exchange between the air and the loaded materials. The oven is suitable for drying, baking, wax melting, constant-temperature treatment, and related applications. Its vertical structure and double-door design provide convenient access to the 640 L chamber. Large thickened glass viewing windows allow operators to observe samples without opening the doors. PID temperature control, automatic tuning, deviation correction, timing, and overtemperature alarms support stable operation. The galvanized-steel working chamber has rounded internal corners and removable adjustable shelves for easier cleaning and flexible loading.
