Atlas Copco ZT90VSD Oil-Free Screw Compressor 90kW

The Atlas Copco ZT90VSD is a 90 kW air-cooled, oil-free rotary screw compressor carrying ISO 8573-1 Class 0 oil-free certification — the highest standard of air purity achievable and the only classification that guarantees zero risk of oil contamination at any point in the compression cycle. The ZT range is Atlas Copco's answer to industries where a single drop of oil in the compressed air stream would compromise product quality, trigger regulatory rejection, or shut down a production line. At 90 kW, the ZT90VSD covers FAD from 60 to 185 l/s at 4 to 10 bar(e), making it the right-sized oil-free solution for mid-scale pharmaceutical manufacturing, food and beverage processing, and critical utility air in sensitive process environments.

The ZT90VSD's two-stage oil-free screw element design achieves compression efficiencies comparable to oil-injected screw compressors without the lubrication contact risk, and the variable speed drive further optimises energy consumption by matching output to demand rather than running at fixed capacity. Atlas Copco's water injection cooling principle in the ZT ensures the compressed air exits the element clean and at low temperature — avoiding the thermal degradation of downstream dryer systems. The Elektronikon® controller monitors all parameters including element temperature, differential pressures, and vibration for early fault detection.

In Saudi Arabia, the ZT90VSD is the compressor of choice for facilities subject to SFDA (Saudi Food and Drug Authority) audit and compliance, where Class 0 oil-free air certification is a mandatory prerequisite for compressed air contact with food products, pharmaceutical granules, tablet coating, and sterile fill-and-finish operations. Saudi pharmaceutical manufacturers in Riyadh's Second Industrial City, Jeddah's industrial zones, and Dammam's Jubail area increasingly specify Class 0 oil-free compressors as they expand export capacity and seek GMP compliance documentation for international markets. The ZT90VSD is also specified for electronics and semiconductor assembly, paint booths requiring zero contamination, and high-purity gas blending operations.

Razz Middle East provides ZT90VSD units with full Class 0 certification documentation, SFDA compliance support dossiers, and locally-based Atlas Copco-certified engineers for installation, validation, and ongoing service in the Kingdom.
