Description
Internal Hot Air Circulation Heat Shrink Tunnel Machine with PLC Control

The S4525N is an industrial-grade, continuous heat shrink tunnel featuring advanced jet-air internal circulation technology. Engineered for high-volume production, it cuts electricity usage by over 15%, maintains precise constant temperatures, and delivers smooth, wrinkle-free packaging across PVC, POF, and PP films.

Key Performance Highlights
  • 15%+ Energy Efficiency: Internal circulation and double-layer heat insulation dramatically reduce power consumption.
  • High-velocity air jet distribution ensures 360° uniform heating for smooth, wrinkle-free shrink results without film distortion.
  • Broad Film Compatibility: Engineered for PVC, POF, PP, and other heat-shrinkable packaging materials.
  • Precision Control: Fully adjustable constant temperature system paired with a stepless conveyor speed regulator.
  • Industrial Durability: Heavy-duty heating components extend overall equipment service life beyond standard market alternatives.
Detailed Equipment Advantages
  • 15%+ Energy Savings & Thermal Retention
    Equipped with an advanced internal hot-air circulation system, the S4525N recycles thermal energy within the chamber rather than venting it. Combined with a multi-layer insulation structure, it minimizes heat loss, drastically cuts electricity usage by more than 15%, and maintains a cool exterior frame for operator safety.
  • Air Jet Technology for Wrinkle-Free Shrinking
    Unlike static heating tunnels, our jet-air system continuously circulates forced hot air evenly around the target package. This balanced thermal exposure eliminates surface bubbles, hot spots, and seal breakage, delivering a clean, tight, and aesthetically superior wrap every time.
  • Broad Compatibility & Rapid Preheat
    The S4525N reaches operational temperature rapidly, keeping production lines moving without lag. It is optimized for high-performance shrink wrapping on PVC film, while offering equal precision for POF and PP films across various product dimensions.
  • Compact Design & Low-Maintenance Build
    Designed with a minimal floor footprint, the machine easily integrates into existing automated lines or works as a standalone station. Modular components and accessible internal compartments allow for fast routine cleaning and maintenance, reducing long-term downtime.
