Hot Air Tunnel Oven

The Hot Air Tunnel Oven manufactured in China by Dingfeng takes into account that thermal uniformity is a fluid dynamics issue. It adopts a proprietary pressurized exhaust system, driven by a 2.2-kilowatt long shaft motor and a 12-inch SUS304 multi-blade impeller. By forcing the hot air through a specially designed internal air collection chamber and precisely drilled distribution plates, we have created a vertical air curtain over a 700-millimeter conveyor belt width.

Qualification Certification

The Dingfeng Hot Air Tunnel Oven for Coating system can store up to 90 days of thermal curves, enabling your quality control team to store and export historical data via USB, thereby providing professional evidence for strict aerospace and semiconductor quality audits. Supported by a high-definition 10.2-inch WynnView touch screen, the touch screen is integrated with Mitsubishi PLC and Delta temperature modules. Unlike ordinary contactors, our SCR output can adjust the current with microsecond-level precision, thus avoiding temperature overshoot.

Frequently Asked Questions

Q1: How do you prevent energy waste in an 88KW high-power system?

A: The 88KW is for rapid initial ramp-up. Once the Mitsubishi PLC stabilizes the zones, the SCR current control switches to pulse-modulation mode. Combined with our dual-layer 120K insulation, actual operating power is significantly lower, maximizing your Energy ROI while maintaining the ±3°C uniformity standard.

Q2: Can this Tunnel oven be integrated into a 1000-level cleanroom?

A: Yes. We offer an optional High-Temperature HEPA/FFU package. The SUS304 mirror stainless steel interior and sealed motor shafts prevent particle generation, making it fully compatible with the strict air purity standards of the 3C and semiconductor industries.

Q3: What is the benefit of the "Side-Opening" doors over standard top-lifts?

A: Standard top-lifts require massive clearance and can be a safety hazard. Our Side-Opening Doors allow technicians to perform maintenance and clean the Down-draft plenum safely and quickly from the floor level, significantly reducing maintenance downtime for 24/7 facilities.
