The cutting-edge energy-efficient KryoSys PO pipe extrusion system makes it possible to halve the length of the cooling section and to reduce energy consumption by up to 30%. The system is suitable for producing smooth mono or multilayer pipes made of PE or PP, with diameters ranging from 110 to 2,000 mm with wall thicknesses up to 150 mm and above and production rates up to 2,700 kg/hr.

With KryoSys the length of the cooling section can be nearly halved compared to conventional extrusion lines, even for large pipe diameters. For example, a 46 m cooling section is sufficient for producing a 400 mm PO pipe with 36.4 mm wall thickness. In a comparable conventional line, assuming an identical output of 1,300 kg/h, the cooling section would have to be 85 m long.

Another advantage of KryoSys is its large energy-saving potential. Through a variety of measures, including a reduction in the number of vacuum and spray cooling baths required for the downstream aggregates and an optimised cooling system consisting of water and air cooling, a total reduction in energy consumption of roughly 185 kW can be achieved.

With energy costs of 0.10 EUR/kWh and 6,000 operating hours per year, this means annual savings of about 100,000 EUR for a single line.

The KryoS pipe head is the heart of the technology success. The modified spiral mandrel distribution pipe head incorporates a temperature controlled cooling section prior to the die set enabling a reduction of the polymer melt temperature by as much as 25%.

The KryoSys system is rounded off by a highly efficient pipe cooling section where the pipe is cooled simultaneously from the outside and the inside by an ingenious combination of water and air cooling, which permits a further shortening of the cooling section.
