Alpine cooling systems for blown film lines
The cooling systems on our blown film lines consist of internal and external cooling, a calibrating and support basket, and an optional post-cooling unit. To ensure you produce blown film with your desired properties, we tailor the cooling system precisely to your line configuration. The individual components work together seamlessly. Thanks to the optimal utilisation of cooling capacity and extended cleaning intervals, your film production runs particularly energy-efficiently.
Alpine Cooling Ring
(External cooling)
Alpine employs a low-back-pressure system in its CRX range. This allows the available cooling capacity to be utilised more efficiently and increases the system’s throughput.
The base unit is fully thermally insulated for improved energy efficiency
Insulation prevents condensation from forming on the outer surface
Optimised air distribution improves control accuracy for optimum film tolerances
Easy integration into the system thanks to a single cooling air supply line
Alpine cooling tower
(Internal cooling)
A unique monomer collection system for paraffin retention prevents paraffin splashes on the film bubble.
Significant improvement in film quality
Significant extension of cleaning intervals
New nozzle geometry reduces back pressure, thereby ensuring optimum utilisation of the available cooling capacity
The high flow rate guarantees maximum production output
Calibration basket and post-cooling
The calibration basket and post-cooling ensure stable bubble guidance and can be flexibly adapted to your system:
- ball-bearing rollers in a V-configuration and centre-guided roller positioning
- high-precision shear principle for optimum film quality
- modular design with various options for monomer extraction or post-cooling
