Features
High Temperature Processing Capability
The Solar Tunnel Oven supports temperatures up to 360℃, making it suitable for high-temperature drying, baking, and curing applications.
Stable Temperature Control
Equipped with OMRON PID temperature controllers and SSR solid-state relay output, the system provides accurate temperature adjustment and stable operation.
Uniform Heating Performance
The optimized airflow circulation structure ensures even heat distribution inside the tunnel and improves product processing consistency.
Clean Production Structure
The inner chamber is made of SUS304 stainless steel with full argon arc welding. Stainless steel components and low-friction conveyor support rollers help reduce particle generation.
Reliable Conveyor System
The conveyor system provides smooth product transportation with reduced vibration, helping prevent scratches, edge damage, and contamination.
High-Quality Drying Results
The optimized heating process helps prevent defects such as bubbles, over-baking, yellowing, and white spots after baking.
Advanced Temperature Monitoring
The six-channel temperature recording system monitors temperature changes in different sections and supports USB data export for process traceability.
Dust and Static Control Design
The inlet dust-removing roller helps maintain conveyor cleanliness, while the outlet static elimination bar reduces electrostatic problems during transportation.
Flexible Customization
The working width, tunnel length, temperature range, conveyor design, and control system can be customized according to customer production requirements.
Safe Operation System
Multiple protection functions, including overload protection, phase protection, emergency stop, and over-temperature protection, ensure safe and reliable operation.
