Atlas Copco Certifies All Its Oil-Free Compressor Technologies Under New ISO 8573-1 2010 Standard

All of Atlas Copco’s oil-free technologies have been certified under the new standard. This includes its centrifugal, tooth, scroll, piston, water-injected screw, oil-free screw and four-stage combined piston and screw machines, as well as its mobile P series of rental compressors. These compressors deliver 100% oil-free compressed air to the textiles, food and beverage, mining, offshore, and electronics (including semiconductor fabrication and clean rooms) industries, as well as to pharmaceutical, chemical and cosmetics manufacturers, automotive plants for paint spraying, municipalities for water treatment and hospitals for critical medical applications.

The first edition of the standard ISO 8573-1 was a first step, in 1991, to acknowledge the importance of air quality and classify air output with respect to the levels of three contaminants: oil, water and dust. The evolution of the standard over time has reflected the ever-increasing needs for air quality for processes and sensitive end products like food and pharmaceuticals. The second edition of the standard, released in 2001, included the CLASS 0 classification for oil content. Atlas Copco was the first manufacturer to obtain the CLASS 0 certification in 2006 from the Technische Überwachungs-Verein who found no oil whatsoever in the compressed air of the Z series of oil-free rotary screw compressors. The other Atlas Copco oil-free technologies (centrifugal, tooth, scroll, piston and water-injected screw) followed suit in 2007, confirming the company’s leadership across the range of pressures from 300 mBar to 40 bar. ISO 8573-1 Ed. 2 (2001) was revised in 2010 to reflect a changed dust content and gave rise to the new standard, ISO-8573-1 Ed. 3 (2010).

“Certification according to the latest 2010 edition of this standard bears testimony to our commitment to oil free technology and to the safety of processes, human beings and the environment,” states Chris Lybaert, President of Atlas Copco’s Oil-free Air Division.

Certificates regarding oil content of the existing Atlas Copco compressor ranges have been issued by the renowned independent Technische Überwachungs-Verein (German Technical Monitoring Association, or ‘TÜV’), based on the most stringent measurement and test methods available. These confirm that no traces of oil could be detected.

One Atlas Copco customer is the L'Oreal factory in Suzhou, China. It uses compressed air for pneumatic devices and dry process after sterilization. Air quality is paramount in the manufacture of high-quality makeup products. Even the slightest traces of oil can result in altered or polluted product batches and the risk of health hazards for consumers. For this reason L'Oreal chose Z series CLASS 0 compressors at the start of production in 1999.

According to Mr. Huang, ETNSE Manager at L'Oreal Suzhou, “We chose Atlas Copco because the CLASS 0 Z range matched our high manufacturing standards and contributed to our ISO 14001 and OHSAS18000 certifications. As an additional benefit, we have managed to reduce the energy consumption of the compressor room by 20%.” The plant received the EFE (Environment Friendly Enterprise) Award, which is the highest award regarding environmental protection from Jiangsu Province, in 2008.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
