Atlas Copco, a world-leading provider of sustainable productivity solutions, has announced the launch of ZR 90-160 VSD+ air compressor.

The latest oil-free rotary screw air compressor from Atlas Copco delivers up to 35 per cent energy savings for a fast return on investment.

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, a new cooler design and an improved monitoring system, said a statement from the company.

This plug-and-play compressor is housed in a compact, soundproof enclosure. It’s the latest air compressor in Atlas Copco’s smart AIR solutions portfolio, it added.

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 optimizes efficiency.

“By adjusting output to match actual needs, the ZR 90-160 VSD+ significantly cuts energy consumption, costs and environmental impact,” remarked Jeroen Hoen, the 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,” stated Hoen.

All components in the compressor element, such as the rotor profiles, smart inlet (patent pending) and rotor coating, have been redesigned for maximum efficiency and durability, he added.

According to him, 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 thus guaranteeing Class 0 oil-free air.

"The redesigned cooler incorporates a highly efficient water separator. Parallel water flow optimises cooling of the motor, element and the cooler itself," stated Hoen.

"Enlarged stainless steel surface coolers improve cooling efficiency and ensure top performance over a long lifetime," he added.-TradeArabia News Service
