Highest efficiency

Over 80% of a compressor’s cost comes from energy use, with compressed air making up 40% of a plant’s electricity bill. The ZR/ZT ensures reliability and efficiency, featuring patented elements for maximum performance and 100% certified oil-free air.

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/ZT 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.

Optimized air flow in the machine

The ZR/ZT 160-315 (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 bare minimum.

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.

SMARTLINK

  • Monitor your compressed air installation with SMARTLINK: Knowing the status of your compressed air equipment at all times is the surest way to achieve optimal efficiency and maximum availability.
  • Go for energy efficiency: customized reports on the energy efficiency of your compressor room.
  • Increase uptime: all components are replaced on time, ensuring maximum uptime.
  • Save money: early warnings avoid breakdowns and production loss.

Energy Recovery: turn your compressor into an energy source

Compressed air is a vital utility for many industries. It is also one of the largest consumers of energy. Our ZR compressors equipped with Energy Recovery can help you reduce energy bills and your carbon footprint. In a typical process, up to 94% of the electrical energy is converted into compression heat, which is lost into the atmosphere via the cooling system and radiation. With Energy Recovery, you can recuperate this energy as hot water for sanitary purposes, space heating or, even more effectively, process applications. By using the hot water as boiler pre-feed or directly in processes requiring temperatures of 70 to 90°C, you will reduce your consumption of more costly, carbon-based energy sources such as natural gas and heating oil.

Dual set-point and automatic stop

Most production processes create fluctuating levels of demand which can lead to energy waste in low use periods. Using the Elektronikon® unit controller, you can switch manually or automatically between two different setpoints to optimize energy use and reduce costs at low use times. In addition, the sophisticated algorithm runs the drive motor only when needed. As the desired setpoint is maintained while the drive motor’s run time is minimized, energy consumption is kept to a minimum.
