The two IP66, water-cooled permanent magnet motors that drive the the ZR 90-160 VSD+ compressor were designed and built in-house, specifically for independently driving the low and high pressure compression elements. These motors contain oil-lubricated bearings to ensure a long, maintenance-free lifetime.
The speed of the elements is controlled using Atlas Copco’s NEOS VSD technology. NEOS optimises the speed of both elements throughout the entire operational speed range of the compressor to maximise unit efficiency. The NEOS drive and motors are designed and manufactured by Atlas Copco to ensure a perfect match and optimal performance.
Why not add an integrated, guaranteed -40°C pressure dew-point dryer that offers almost zero energy consumption? This Full Feature package offers you true peace of mind, reduced installation materials and a through-life cost of ownership investment lower than any comparable oil-free compressor available today.
Investing in oil-free technology is the best way to safeguard the integrity of your process and guarantee the quality of your product. Our ZR VSD+ range is certified to deliver Class 0 and is made on a production line that is compliant with ISO22000. But your compressed air system is not made up only of your compressor. Sensitive applications such as pharmaceuticals, food and beverage, electronics and automotive have stringent requirements where air quality is concerned, most commonly defined through the ISO8573-1:2010 standard. This standard defines the maximum level contaminants (particles, water and oil) which can be present in the compressed air used for an application.
Most commonly, sensitive applications such as these highlighted require dry compressed air. Because traditionally compressors with integrated dryers are only available with a refrigerant dryer option (enabling a compressed air pressure dew point of +4°C), the dry air requirement meant your compressed air system had to include a desiccant dryer to achieve the standard needed. The most common solution was to add a heated blower purge dryer such as our CD+ or BD+ range of desiccant dryers, though Atlas Copco now offers zero purge options. The ZR VSD+ range of oil-free compressors offers a different method to meet your quality requirements. By integrating our most efficient compressed air drying technology, the latest ZR compressor offers you the benefit of a 25% smaller footprint for your installation and compressed air with a pressure dew point of -40°C at the compressor outlet. This is alongside the benefit of a reduced pressure drop that would have been brought on by the external dryer and required filtration. Recalling that lowering your compressor's pressure output by only 1 bar saves 7% in energy requirement, the financial benefit of a lower pressure drop becomes obvious.
Following years of intensive R&D we’re proud to unveil our latest leap forward in oil-free compressor technology. Not only does the innovative dual-motor concept enhance energy efficiency and output by up to 15 and 10 per cent respectively, but there is the optional benefit of having an integrated, guaranteed -40°C pressure dew-point dryer that offers almost zero energy consumption. This Full Feature package will offer users true peace of mind, reduced installation materials and a through-life cost of ownership investment lower than any comparable oil-free compressor available today.
The latest range of ZR 90-160 VSD+ compressor has so many benefits compared with other oil-free VSD compressors, that it truly can be called a leap forward in compressor technology.
The range is ideal for applications in the food & beverage, electronics, automotive, textile and pharmaceutical industries, which require oil-free air to guarantee product integrity and quality. Read more in our press release.
