QWO Oxygen-Free Oven
Merchandise number：QWO
Description：
- Effectively saves 30% of nitrogen consumption.
- With excellent airtightness, it can reduce the O2 to as low as 10 ppm.
- Special Pressure Relief Design.
Features
10ppm Oxygen-Free Key Technology- Special Pressure Relief Design: Utilizing an adjustable exhaust valve in conjunction with air intake control to maintain positive pressure inside the oven, ensuring a low-oxygen environment.
- Enhanced air tightness is achieved at the tubular heater cable outlet through a unique hermetic seal design.
- N2 Throttling Design： Segregating the supply conduit into two - main and auxiliary – and with automated flow regulation.
- Cooling inter-layer design：a special indirect method to maintain an oxygen-free environment during cooling phase.
- Inner door design： establishing an invisible barrier of nitrogen gas that not only prevents external gases from entering but also inhibits heat dissipation.
- The inter-layer and the space between the inner and outer doors are filled with nitrogen (N2) to recover conducted waste heat for energy-saving.
Applications
IC packaging, wafer baking, film deposition and other industry manufacturing for drying productions. The equipment such as semiconductor drying equipment, circuit board drying equipment, PCB industrial oven, touch panel drying equipment, ABF carrier board drying equipment, precision industrial oven.
