Indonesian textile manufacturer depends on oil-free Atlas Copco centrifugal compressors

2014-07-25

Wilrijk, Belgium, July 2014:  In the Primayudha Mandirijaya Pt. textile factory, an Atlas Copco ZH 350+ centrifugal compressor supplies oil-free air for production processes throughout the facility. As the factory has become more automated, the use of high quality compressed air has increased substantially.

ZH 350  compressor
Established in 1996, Primayudha Mandirijaya Pt. started the commercial production of yarn in 1998. The company has a 50-acre factory in Desa Ngadirojo Boyolali in Central Java with approximately 1,200 employees. The factory has a production capacity between 95,000 and 120,000 bales of yarn per year.

Most important: constant pressure

In 2012, Primayudha Mandirijaya Pt. bought an Atlas Copco ZH 350+ centrifugal air compressor with 7 bar pressure and 350 kW to control the valves and cylinders for its spinning and winding processes. On the winding machine, compressed air is used to splice yarn, and the air-jet loom requires compressed air for the insertion of weft. Compressed air is also needed during the weaving process. 

High quality air is essential in integrated textile units. Atlas Copco was the first manufacturer to provide the textile industry with energy-efficient and reliable oil-free compressed air solutions that allow yarn production at a relatively high rate. 

“Constant pressure is the most important element in our factory,” said Mr. Mukesh Garg, Production Manager for Primayudha Mandirijaya Pt. “Before we purchased the compressor, we compared different brands of products and learned that only Atlas Copco centrifugal compressors satisfy our demands for pressure and provide us with high productivity.”

ZH 350+ oil-free centrifugal compressor eliminates risks

During the air-jet spinning process, cotton is spun into yarn with compressed air supplied through fine nozzles. Oil in the compressed air can clog the nozzles and stain the yarn, which is in direct contact with the compressed air. Expensive nozzle replacements, production losses and rejection of the product by the customer can result.

Atlas Copco’s ZH 350+ oil-free centrifugal compressor provides Primayudha Mandirijaya Pt. with 100% pure, clean air that complies with ISO 8573-1 Class 0 (2010) certification. Class 0 means zero risk of contamination; zero risk of damaged or unsafe products; and zero risk of losses from operational downtime.“To protect our reputation and product quality, we had to select a reliable and oil-free machine to support our production process,” said Mr. Mukesh Garg. “Atlas Copco’s centrifugal air compressor ZH 350+ has shown a very good performance. As a testament to their trust in Atlas Copco compressors, Primayudha Mandirijaya Pt. purchased another Atlas Copco unit – a ZH 500+-9 centrifugal compressor – in November 2013. Delivered as a plug-and-play package, the ZH 500+-9 employs advanced aerodynamics to reduce energy consumption in the core and reduce pressure drop from cooler, inlet filter and optimized part design. It saves up to 7% on specific energy at full load and up to an additional 9% at partial load. The new machine arrived at Primayudha Mandirijaya Pt. in April 2014. “We hope this new machine will help us to increase our production reliability, safeguard the quality of our product, and also achieve maximum energy savings,” said Mr. Garg. Equipment Spotlight ZH 350+- Directly driven by a permanent magnet synchronous motor for high-speed, efficient operation- Optimal three-stage compression reduces operating costs- 100% certified oil-free air that meets ISO 8573-1 Class ) (2010) standards- Equipment Spotlight ZH 500+- Packaged plug and play unit- The most “energy efficiency” compressor ( average 10% saving compared to competitor)
