Air-Cooling-Ring Systems
For a maximum performance of your production lines!
The decisive factor for the film quality and performance of blown-film extrusion lines is the air ring. Therefore Kdesign has developed the high-performance air ring KARAT , which has been proving its productive efficiency on several hundred lines, day by day.
The development of the KARAT air ring is based on substantial fluidic studies and thorough practical tests, along with our customers.
The high-performance air ring KARAT stands out for:
- Highest cooling rate
- Improved film tolerances
- Absolute even air distribution
- Excellent bubble stability
- Maximum air flow, minimum pressure drop
- Easy handling
- Optimal retrofitting of gauge control system VARIOcool

Small step – but huge effect!
The replacement of your existing air ring by a high-performance air ring KARAT represents a small investment which will pay off rapidly. The retrofitted lines attain a considerable production increased (regularly over 25%) and an improvement of the film tolerances.
In addition to our Karat air rings we offer a wide range of auxiliary equipment:
- Motorised lip adjustment:
For an easier handling of bigger air rings and a reproducible adjustment of the air ring - Lifting devices:
For an easier start-up and die gap cleaning - Housing insulation:
To avoid the forming of condensed water - Air distribution systems:
Low pressure drop, for a direct connection with the air ring - Blowers and heat exchangers:
