Atlas CopcoLow pressure oil-free air compressors(Atlas Copco screw Air Compressor) Model ZE2 air-cooled - 60 Hz and ZA2 water-cooled - 60 Hz
The preferred choice for total reliability and efficiency
1.State-of-the-art screw compression element
Unique Teflon coating results in increased efficiency, higher pressures up to 4 bar(e)/58 psig, longer lifetime and protection against corrosion.
Cooling jackets improve reliability and efficiency by ensuring rotor clearances are always kept to the absolute minimum.
Efficient shaft sealing eliminates the risk of oil leakage, reduces wear, and guarantees 100% oil-free air.
2. Advanced element bearings
Assuring constant reliability, the element bearings remain stable under varying load conditions.
Durability is a given: two axial bearings limit internal leakage losses by maintaining small clearances between the rotor surfaces.
The bearings adapt easily to changing loads, providing the flexibility and efficiency to make production processes run smoothly.
3. Control and monitoring
To keep a firm grip on costs, the advanced Elektronikon® system allows you to monitor overall system performance with service indications, malfunction alarms and safety shutdowns. The multi-language text display is easy to use.
For extra flexibility, the Elektronikon can be integrated into existing process control systems.
To increase efficiency and minimize downtime, two control algorithms (Dynamic Pressure Limit Control and Dynamic Speed Limit Control) tune setpoint pressure and operating speeds to element discharge temperature.
4.High-precision drive system
Even in dusty and humid environments, the high-efficiency IP55 motor (efficiency class EFF1) offers assured operation.
Transmission losses are low, noise and vibration levels are decreased and element lifetime is prolonged thanks to the AGMA Q13/DIN Class 5 gears in the main drive.
Since no pulleys are used, the replacement of belts and misalignment of elements is avoided, while mechanical losses are limited.
5. Air-cooled aftercooler (ZE only)
User-friendliness is increased and costs reduced thanks to easy installation and easy access for cleaning.
The highly efficient cooling reduces energy consumption and dryer loads.
