Atlas Copco ZR110 Oil Free Rotary Screw Air Compressor

The Atlas Copco genuine ZR110 water-cooled rotary screw compressor delivers certified 100% oil-free compressed air for continuous, high-capacity industrial manufacturing plants. Certified compliant with ISO 8573-1 Class 0 standards, this heavy-duty package completely eliminates oil contamination risks across automotive surface coating, electronics fabrication, and continuous chemical production processes.

Driven by a high-efficiency 110 kW electric motor, the ZR110 utilizes two-stage dry screw compression to achieve optimal thermodynamic efficiency across 7.5 bar, 8.6 bar, 10 bar, and 13 bar working pressure variants. By dividing total compression into low-pressure and high-pressure stages separated by a high-efficiency water-cooled intercooler, the compression cycle significantly reduces specific energy consumption compared to single-stage units.

Both dry screw elements feature precision-engineered asymmetrical rotor profiles coated with Atlas Copco proprietary thermal barrier coating, preventing surface oxidation and preserving tight volumetric running clearances under high thermal loads.

External synchronizing timing gears lubricated by an isolated oil circuit ensure that the male and female rotors never make physical contact inside the compression chambers, eliminating the need for oil injection. Multi-stage floating carbon ring seals backed by atmospheric air purge galleries provide an impenetrable mechanical barrier that prevents gearbox oil vapors from migrating into the clean compressed air stream.

The integrated water-cooling circuit utilizes heavy-duty shell-and-tube heat exchangers with corrosion-resistant tubes, efficiently dissipating heat from the intercooler, aftercooler, and lubrication system. This design maintains stable interstage air and lubricating oil temperatures even in hot ambient plant environments.

Operated by the intelligent Elektronikon microprocessor controller, the system continuously tracks interstage pressures, water flow temperatures, running hours, and preventative maintenance intervals.

Constructed on a rigid structural steel base frame with sound-attenuating canopy panels, every unit is prepared on export-grade wooden skids with comprehensive weatherproofing for safe international ocean transport.
