Frequently Asked Questions
Common questions about the ZF-S450.
How much energy does an energy-saving shrink tunnel save? +
The downwind circulation system with 100mm insulation saves 2-3KW/H compared to ordinary shrink machines, significantly reducing operating costs over the machine's lifetime.
Which sealing machines pair with a shrink tunnel? +
Shrink tunnels pair with all types of sealing machines — L bar sealers, reciprocating sealers, and tire packaging systems. A shrink tunnel is a universal complement in any packaging line.
What is the temperature control accuracy? +
Automatic temperature control within ±1°C ensures consistent shrink results across all product types and film materials.
What warranty is provided on key components? +
Main electrical heating pipes and fan motors are guaranteed for 10 years — industry-leading coverage that reflects our confidence in component quality.
What are the available shrink tunnel sizes? +
Four models available: 450mm, 550mm, 650mm, and 800mm tunnel widths. Power ranges from 9.6KW to 23KW at 380V/50HZ. Choose based on your product size and production volume.
Which industries use heat shrink tunnels? +
Shrink tunnels are essential for food & beverage, pharmaceuticals, cosmetics, electronics, and tire manufacturing. Any product requiring tight, professional shrink film wrapping needs a tunnel.
What are the key features of an energy-saving shrink tunnel? +
Downwind circulation with 100mm insulation saves 2-3KW/H, ±1°C automatic temperature control ensures consistent results, adjustable wind power and direction, and 10-year warranty on heating pipes.
Is a shrink tunnel a standalone machine? +
No. A shrink tunnel is supporting equipment that pairs with a sealing machine (L bar sealer or reciprocating sealer) to complete the shrink wrapping process.
