Rochman Heat Tunnel

• Shrink wrapping individual products or multi-packs for retail presentation.
• Protecting goods from dust, moisture, and tampering during storage and transit.
• Creating tamper-evident seals for food products, pharmaceuticals, and cosmetics.
• Bundling multiple items together for promotional offers or logistical efficiency.
• Applying protective film to items for improved durability and shelf life.

Typical throughput

Varies significantly based on product size and film type, but units of this class commonly achieve 10-30 packs per minute.

Power supply

Typically requires a 3-phase industrial power supply, commonly 400V, 50Hz, with varying amperage requirements.

Tunnel aperture

For this model (TR45-90), the '45' likely indicates a typical tunnel width of around 450mm, and '90' a height of approximately 200-300mm. Buyers should confirm exact dimensions.

Conveyor type

Units of this type commonly feature a mesh belt or roller conveyor, with adjustable speed control.

Heating elements

Typically uses electric heating elements with thermostatic control for consistent temperature regulation.

Footprint

A unit of this size would typically require a floor space of approximately 1.5m to 2.5m in length, and 0.8m to 1.2m in width, excluding infeed/outfeed conveyors.

• What types of film can this heat tunnel process?

  Rochman heat tunnels are typically designed to work with various shrink films, including PVC, POF (polyolefin), and PE (polyethylene), depending on the specific model and heating capabilities. Buyers should confirm film compatibility with the seller.

• Is this unit suitable for food packaging?

• What maintenance is typically required for a heat tunnel?

• Can the tunnel temperature and conveyor speed be adjusted?

• What safety features are commonly found on these machines?

Used sealing machines are generally valued for their durability and long operational life. Buyers typically prioritize machines with clear maintenance histories and minimal wear on sealing components. Key considerations include film compatibility, seal quality consistency, and ease of adjustment. Reputable models tend to retain functionality well across multiple applications. Industry sentiment suggests these machines offer strong value when sourced from reliable vendors, though operators should verify calibration settings and test seal integrity before full production use.
