The Wincom DHG-9101-OSA (often classified within the DHG series) is a high-precision electrothermal constant-temperature blast drying oven and thermostat incubator designed for laboratory and industrial applications. Manufactured by Wincom Company Ltd., this unit utilizes a forced-air “wind blow” convection system to ensure uniform heat distribution for drying, baking, sterilizing, and sample incubation.
Key Specifications & Technical Features
- Temperature Control Range: Typically operates from Room Temperature (RT) +10°C up to \300°C (some variations cap at 250°C depending on incubator vs. oven tuning).
- Temperature Fluctuation: Maintained within a highly stable pm 1°C.
- “Wind Blow” Forced Convection: Equipped with a low-noise axial fan paired with optimized air ducts. This creates a continuous hot-air circulation system so that heated air flows directly through objects for uniform thermal processing.
- Chamber Material: Constructed with a heavy-duty stainless steel inner chamber designed for corrosion resistance, long-term durability, and easy cleaning.
- Smart Controller: Features a microcomputer-based PID intelligent digital display. It tracks target and real-time temperatures simultaneously and includes built-in timers (ranging from 1 to 9,999 minutes).
- Safety Protections: Outfitted with automatic over-temperature visual/audible alarms, electricity leakage protection breaks, and sensor fault indicators.
- External Design: Built with an outer high-quality steel sheet finished with electrostatic spraying. The front door features a tempered, double-layer glass observation window to monitor materials safely without losing chamber heat.
Primary Applications
- Laboratory Operations: Sterilizing glassware, sample dewaxing, and moisture testing.
- Industrial & Mining: Material heat treatments, component baking, and thermal aging tests.
- Biochemical Incubation: When dialed to lower thresholds, it acts as a constant-temperature chamber for non-critical microbial setups requiring active air circulation.
