Discovery 10T

Discovery 10T

Air ring with sectoral thermal modulation

Discovery 10T is designed for the extrusion of LD or HD blown film. It is equipped with a sectoral thermal modulation cooling flow and can be installed between the extruder die and the customers’ existing ring.

With Discovery 10T productivity can be increased, and in combination with the thickness control system it is capable of ensuring superb gauge uniformity.

  • Reduction of the 2 Sigma value
  • Increased productivity
  • Reduction of start-up times
  • Suitable for retrofitting on existing systems
Discovery 12T

Discovery 12T

Automatic air ring with thermal modulation

DISCOVERY 12T is an innovative dual-flow automatic cooling ring with sectoral thermal modulation that allows precise automatic thickness adjustment.

Its exclusive design provides two distinct cooling flows to ensure effective regulation of the point-to-point thickness and greater cooling efficiency with reduced energy consumption.

  • Dual-flow system
  • High definition bubble check
  • Reduction of the 2 Sigma value
  • Reduction of start-up times
Discovery 13T

Discovery 13T

Multi-flow cooling ring with automatic sector adjustment

DISCOVERY 13T is a high performance cooling ring with triple cooling flow. The three cooling flows combined with the thermo-regulated sectors enable proper bubble support and consistent gauge control along the entire circumference offering a substantial increase in productivity.

The installation of the DISCOVERY 13T automatic ring allows the improvement of the 2 Sigma value. DISCOVERY T13 is managed by NAVIGATOR 9000 which, through the touch view control, guarantees a simple and intuitive interface.

  • Independent triple flow system
  • Air flow with sectoral thermal modulation
  • Energy saving features
  • Reduction of start-up times
Atlantis 23T

Atlantis 23T

Adjustable triple-flow ring with thermal sector modulation

ATLANTIS 23T is an innovative high-efficiency multi-flow automatic cooling ring with sectoral thermal modulation that allows precise and automatic gauge adjustment. As the Discovery line, this cooling ring maintains precision in thickness control and management, enabling the operator to realize quick and easy adjustment and preparation for production startup and changeover.

It improves production changeover times and, together with the LIFTER, increases productivity by automatically raising the upper part of the ring to the optimal position. This further enhances the mechanical film properties and improves both quality and productivity.

  • Designed for high production
  • High bubble stability
  • Uniform film profile
  • Carbon fiber construction


Motorized lifting system

LIFTER is a motorized system that adjusts the mobile part of the ATLANTIS ring to the most suitable position required by the processing resin typology, thereby ensuring that the frost line is positioned correctly.

The innovative design enables higher cooling of the blown film and further maximizes overall production efficiency.

  • Compatible with ATLANTIS 23T
  • Optimal cooling efficiency
  • Easy operations
