Blow Air Cooling

Internal product cooling with compressed chilled air

Extrusionsblasformen

Cooling the product is the longest and most critical part of the solidification process.

The fact that the mould only removes heat from the outside surface of the container causes material stress and extended cooling time in the mould.

Blue Air Systems’ Blow Air Cooling units replace the regular blowing air with chilled compressed air inside the container during the blowing process. As a result the heat is removed also from the inner surface of the container reducing material stress and cutting cooling time up to 50 %. Blue Air’s Blow Air Cooling Systems stand for an important contribution to increased production and improved quality in the field of extrusion blow moulding.

Compressed Air Chiller CAC

Internal product cooling by Compressed chilled air

The Compressed Air Chiller (CAC) replaces the regular blowing air with chilled compressed air (-35°C) inside the container during the blowing process.
