Atlas Copco has launched its latest oil-free rotary screw air compressor, the ZR 90-160 VSD+. It delivers up to 35 per cent energy savings for a fast return on investment, according to the company. The new ZR is available with or without integrated dryer. The water-cooled ZR 90-160 VSD+ is equipped with two high-efficiency permanent magnet motors, state-of-the-art compressor elements, a new cooler design and an improved monitoring system. This plug-and-play compressor is housed in a compact, soundproof enclosure. It is the latest air compressor in Atlas Copco?s smart AIR solutions portfolio.

The drive design of the ZR 90-160 VSD+ incorporates Atlas Copco?s most sophisticated variable speed drive (VSD) technology: NEOS drives combined with permanent magnet motors. The dual motor concept with a smart control algorithm allows both elements to be run at different speeds, which optimises efficiency.

?By adjusting output to match actual needs, the ZR 90-160 VSD+ significantly cuts energy consumption, costs and environmental impact,? said Jeroen Hoen, Product Manager, Oil-free Compressors. ?The internal IP66 water-cooled permanent magnet motors, designed for class-leading efficiency and high reliability, contain oil-lubricated bearings for a long maintenance-free lifetime. Moreover, all service parts are grouped together for ease of access for a minimal service time.?

The ZR 90-160 VSD+ can be included in a Total Responsibility Plan, in which Atlas Copco takes care of all compressor maintenance, upgrades, repairs and possible breakdowns.
