Wittmann - Blow Air Chiller Get latest price

Material & Workmanship:

• Outer housing made of brushed stainless steel
• High quality refrigeration compressor
• Fully insulated internals to prevent sweat
• Crane hook
• Water- and oil separators to clean the compressed air
• Activated carbon filter to also remove chemical residues 

Product Benefits: 

• One of the most critical and at the same time the most lengthy sub-process in extrusion blow molding is the cooling of the plastic parts, as the temperature gradient between the cold water-cooled outside and the warmer inside causes material stress. This degrades the quality and can lead to failure in leak, load and/or drop tests. Therefore, a system to chill with cold compressed air from the inside has been developed for many years, the Internal Air Cooling System (IACS).
• This increases productivity by up to 200% while helping to improve the quality of the products by exchanging cold air inside of the blow moulded product during the cooling phase. This ensures that material stress is reduced and the cooling time is automatically reduced. In most cases, material savings of up to 10% were achieved. The payback periods, according to our experiences, are between two weeks and six months.
