Kallfass Shrink Tunnel STANDARD 650 NT

Universally applicable high-performance shrink tunnel with side-adjustable air flaps and externally adjustable bottom air outlets for precise control of the hot air flow, ensuring optimal shrink results even with challenging product contours. The recirculation system, a tunnel hood with an additional double-chamber system, and significantly enhanced all-round insulation provide energy-efficient operation. Equipped with infinitely variable rod chain conveyor.

This tunnel is suitable for use with all shrink films, especially polyethylene (LDPE) or polyolefin films, in medium to high performance ranges.

Comprehensive standard features:
• Silicone-coated transport rods, rod spacing 25 mm, rod diameter 12 mm
• Infinitely variable speed adjustment for the rod chain conveyor
• Wear-free, contactless temperature control
• Energy-saving, highly effective thermal insulation of the tunnel hood
• Temperature control via electronic thermostat
• Air outlet flaps adjustable from outside during operation
• Fixed clearance height 200 mm
• Adjustable working height
• Safety equipment in accordance with EC Directive EN 60204: over-temperature monitoring
• Machine design complies with EC Machinery Directive 98/37/EC (CE mark), built to EN/VDE standards and relevant accident prevention regulations for the food and beverage industry (GS test mark)
