Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant’s total electricity bill. The ZR is not only designed for reliability, but also for efficiency. Our unique and patented elements are designed in-house for maximum efficiency. The superior rotor coating, compact rotor profiles and cooling jackets guarantee maximum compression efficiency. The unique Z seal design guarantees efficient and 100% certified oil-free air for your application.
Highest efficiency
Designed for VSD
Compressors don’t always run at full load, because your application often has a varying air demand. Atlas Copco’s VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in large energy savings of up to 35%. The elements of the ZR are designed for VSD machines to run efficiently at the broadest possible range. For this unit we also designed our own NEOS inverter to constantly optimize the motor speed and our own Permanent Magnet Motor for class-leading efficiency.
Energy cost: 42%
Energy savings with VSD: 35%
Investment: 12%
Maintenance: 11%

VSD⁺ concept
The ZR VSD⁺ range with its dual NEOS drives has the widest operating range on the market today. These units can operate from 11 to 100% load without wasting energy from unloaded operation, resulting in huge energy savings during periods of low to medium air demand. Another advantage of the dual NEOS drives is that the ZR VSD⁺ always works at optimal efficiency at any pressure, when comparing to standard fixed speed and VSD machines that have a fixed gear ratio.
Optimized air flow in the machine
The ZR 200-355 VSD⁺ brings cool dense air into the package for optimal compression efficiency. The piping and components are strategically placed to minimize the pressure drop in the package, leading to optimal efficiency. The coolers have been carefully designed to keep the pressure drop at a bare minimum. Our zero loss drains account for zero waste of compressed air, making the ZR VSD⁺ the most efficient machine on the market.
Elektronikon® Mk5 Touch control
80% of your costs with a compressor come from energy consumption. The Elektronikon® compressor monitoring system saves energy by using:
Delayed second stop to stop the compressor whenever possible.
Dual pressure band for lower pressure in the systems during weekends and nights.
Automatic main motor speed adjustments depending on air demand.
Adapting dryer speed according to your needs.

Energy Recovery
You can turn your compressor into an energy source. Air compressors equipped with Energy Recovery can help you achieve your goals in becoming carbon neutral. Compressed air is one of the most important utilities for the industry. It is also one of the largest consumers of energy. Up to 94% of the electrical energy is converted into compression heat. Without energy recovery, this heat is lost into the atmosphere via the cooling system and radiation. You can use hot water recovered from the compressed air system for sanitary purposes and space heating. But it is particularly suitable for process applications. Using the hot water as boiler pre-feed or directly in processes requiring 70 to 90°C can save you costly energy sources such as natural gas and heating oil.
