Pester Pewo Therm 11

• Shrink wrapping of individual products or multi-packs in the packaging industry.
• Heat-shrinking labels onto containers in the food and beverage sector.
• Drying of coated or washed components in manufacturing processes.
• Curing of certain adhesives or coatings on various substrates.
• Pre-heating of materials before further processing steps.

Typical throughput

Throughput for this class of heat tunnel is typically dependent on product size, film type, and desired shrink quality, often ranging from 10 to 60 packs per minute.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz, with power consumption varying based on tunnel length and heating elements.

Heating method

Pester Pewo Therm tunnels generally utilise electric heating elements with forced air circulation for even heat distribution.

Temperature range

Operating temperatures are typically adjustable, commonly ranging from 100°C to 250°C, suitable for various shrink films.

Conveyor type

Heat tunnels often feature a mesh or rod conveyor, with adjustable speed to control dwell time within the heated zone.

Footprint

The overall footprint for a heat tunnel of this capacity can vary, but typically requires several square metres of floor space, including infeed and outfeed areas.

• What types of film can a Pester Pewo Therm 11 typically process?

  This model is generally suitable for processing a range of shrink films, including PVC, POF (polyolefin), and PE (polyethylene), depending on film gauge and specific application.

• Is this unit suitable for food contact applications?

• What maintenance is typically required for a heat tunnel?

• Can the tunnel speed and temperature be adjusted?

• What safety features are commonly found on these units?

Heating and drying equipment for food processing is valued for consistent performance and long operational life when properly maintained. Buyers typically prioritise units with robust construction, reliable temperature controls, and documented maintenance history. Common strengths include energy efficiency and compatibility with existing production lines. When purchasing used models, inspectors should verify heating elements function reliably, check for corrosion or wear affecting interior chambers, and confirm all temperature gauges read accurately. Equipment from reputable manufacturers generally commands confidence in the second-hand market.
