Blow Air Chiller

In Stock

Product Features: 

• The Blow Air Chiller (BAC) is our top performer in internal mold cooling: powerful and equipped with the FIT controller to get the most out of your system.
• The compressed air is cooled down to -35 °C in the BAC – this requires good quality compressed air.
• A residual oil content of maximum 0.01 mg/m³ and a maximum pressure dew point of 5 °C at 7 bar are an important prerequisite to avoid problems, as oil would destroy the molecular sieve in the PAD.
• The adsorbent serves to lower the dew point of the compressed air far enough to prevent freezing of the moisture in the system.
• With optimum quality compressed air, you can take advantage of the maximum benefits of internal mold cooling! 

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.
