Atlas achieves ISO certfication
Atlas Copco Compressors, the supplier of air compressors for PET bottle blowers, has demonstrated its commitment to oil-free technologies by achieving ISO 8573-1 Class 0 certification for its ZD 40bar compressor.
The Hemel Hempstead firm said being Class 0 certified meant it had eliminated the risk of oil contamination during PET bottle blowing for bottled water, soft drinks and fruit juices.
Independent testing was carried out by the German Technische Überwachungs-Verein. All possible forms of oil contamination were measured at three different temperatures and pressures and no traces of oil were found in the output air stream.
Atlas Copco Compressors has now reached the ISO standard for its ZD compressor, in addition to its 2006 certification of the Z series of rotary screw compressors. Together these span a pressure range from 300mbar to 40bar.
The ZD offers four-stage compression, an optional integrated variable speed drive and a silencing canopy. It can simultaneously deliver both high-pressure air for blowing needs and medium-pressure air for labelling, instrumentation and capping.
