The company’s decision to install two oil-free compressors, the ZT37 VSD and the ZT18, together with new AIRnet pipework, was influenced by the need to ensure optimum air quality and product purity. Atlas Copco’s process air complies with the standard of air purity, ISO 8573-1(2001), and also embraces the Class 0 industry standard which measures all three forms of oil contamination: aerosol, vapour and liquid.
Prince Gate’s compressor upgrade was influenced not only by the need for guaranteed 100% oil-free air, but also for the production environment benefits of lower operational noise levels and the elimination of the time and costs involved in oil condensate disposal. What’s more, the integrated frequency converter feature of the Atlas Copco VSD (variable speed drive) compressors varies the speed of the drive motor to exactly match the changes in compressed air demand, thus using the minimum amount of energy and saving up to 35% in energy consumption costs.
The net effect of these production line improvements has now enabled Princes Gate’s management team to put plans in place for increasing the company’s annual output to 70 million bottles and to undertake a major expansion of retail sales.
“ The Atlas Copco equipment is proving to be very efficient. It produces the 100% oil-free, high quality, dry air we need and is extremely reliable. In our view, the installation of the compressor plant was carried out very professionally and we have no hesitation in recommending Atlas Copco’s equipment to other companies. ”
