With the new Efficient Air Cooling (EAC), the internal air cooling system from Battenfeld Extrusionstechnik GmbH, Bad Oeynhausen, pipe manufacturers are now easily able to improve the quality of their pipes and simultaneously increase their production output.<\/p>\n
The new system can be used in the production of both mono-layer and multi-layer polyolefin pipes. It is suitable for all pipe diameters between 63 and 2,000 mm with wall thicknesses of up to 150 mm. A special advantage is that EAC can not only be directly integrated into new dies, but also easily retrofitted to any existing VSI die. The benefit of EAC becomes immediately evident in production: the innovative cooling system allows a significant increase in production output or shortening of the cooling section, which is a considerable advantage especially where space is limited. At the same time, EAC ensures an improvement in product quality. The sagging effect is avoided, and the deformation of pipe ends following cutting significantly re-duced.<\/p>\n
Efficient Air Cooling has already left its development stage behind. The first system is in operation at Westf\u00e4lische Kunststoff Technik GmbH (WKT), Sprockh\u00f6vel, Germany, in combination with a PO 500 VSI (T) die. “We are enthusiastic about the in-crease of up to 50% in output in the same pipe size. We have not found any impairment in product quality either. The inner surface of the pipes is absolutely smooth, and the deformation of pipe ends following cutting has been significantly reduced”, Stefan Depmer, WKT is pleased to note.
\nEAC provides effective cooling of pipes from both inside and outside, using nothing but air. In the interior of the pipe, cooling is effected by means of air exchange, with the hot air being sucked off. Simultaneously, the mandrel inside the die is cooled via a special mechanism, and finally the outside of the pipe is also supplied with cooling air. In this way, the pipe is very evenly cooled, which reduces tension inside the pipes and deposits on the inner surface. Systems using exclusively air for cooling are not only efficient but also easy to operate and require little maintenance.<\/p>\n
A positive side-effect can be achieved by using the hot air sucked off from the interior of the pipe for pre-heating granulate. This reduces the extruder’s energy consumption and boosts the efficiency of the line. This means that the ROI for an EAC is reached very quickly, in less than one year.<\/p>\n","protected":false},"excerpt":{"rendered":"
