Hot Water Tunnel 500 HWT

Request More Information ›

The 500 HWT Hot Water Tunnel is designed for use with Ossid end-seal machines and provides hot water shrink to maximizing package integrity. This waterfall style tunnel can be ordered with new Ossid tray overwrappers or can be integrated with Ossid end-seal machines already in the field.

The Ossid 500 HWT generates hot water via electricity, allowing the water tunnel to hold a tighter temperature tolerance vs. a traditional steam tunnel system. Each system works separately giving processors the option of only running the lines they need.

The 500 HWT is ideal for companies seeking more control and consistent temperatures.
