Atlas Copco Offers New ZR 90-160 VSD+ Oil-Free Rotary Screw Air Compressor With Dual Element and Motor Design

Atlas Copco Compressors has expanded its oil-free air compressor offering with the introduction of the new ZR 90-160 VSD+ (120-200HP) - delivering an average of 12 percent energy savings when compared to the previous industry-leading savings of the former generation. The most recent version of the ZR series provides the latest technology in oil-free rotary screw air compressor innovation – available with or without an integrated dryer; savings of up to 35 percent are possible depending on the application.

Ideal for applications in the food and beverage, electronics, automotive, textile and pharmaceutical industries, the water-cooled ZR 90-160 VSD+ is equipped with two high-efficiency permanent magnet motors, state-of-the-art compressor elements, and a redesigned monitoring system. 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 allows automatic variable synchronization of the independently driven airends ensuring maximum operating efficiency at every speed.

Clean and dry air is guaranteed. The ZR 90-160 VSD+ is available with an integrated MDG rotary drum dryer, providing a stable and guaranteed pressure dew point of -40°F at almost zero energy cost. The design and sealing of the venting chamber ensure physical separation between the oil and air circuits, eliminating any possibility of oil entering the compressed air chamber and guarantees Class 0 oil-free air.

“The latest generation of ZR compressors significantly cuts energy consumption and reduces environmental impact by adjusting output to match process needs,” says Neil Breedlove, vice president of oil-free air solutions in the United States. “Its adjustable water-cooled motor features full regulation between 15 to 100 percent of the maximum capacity to save even more energy at reduced air demand.”

All components in the compressor element, such as the rotor profiles, smart inlet and rotor coating, have been redesigned for maximum efficiency and durability. The IP66 motors and new drivetrain offer complete protection from dust and moisture – while maintaining extreme levels of efficiency. The new ZR models can work in extreme temperatures up to 131° F (55°C). All this is possible with a footprint that is up to 20 percent smaller than comparable machines on the market.

The redesigned cooler incorporates a highly efficient water separator. Parallel water flow optimizes cooling of the motor, element and the cooler itself. Enlarged stainless steel surface coolers improve cooling efficiency and ensure top performance over a long lifetime.

The ZR 90-160 VSD+ is equipped with the new, user-friendly Elektronikon® Mk5 Touch Controller to optimize system pressure and maximize energy efficiency. The new Touch Controller includes warning indications, maintenance scheduling and online visualization of the machine’s condition. This works together with Atlas Copco’s new Optimizer 4.0 central controller. It enables a compressed air system to be optimized through selection of the most efficient combination of air compressors while assuring supply of required pressure and having balanced running hours.

The data monitoring program, SMARTLINK is integrated as a standard feature. This remote monitoring system provides analysis of the whole compressed air system on how you can reduce energy costs and plan your preventive maintenance. 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.
