Volkswagen and Veolia in industrial heat recovery project for local community

Veolia Energy Poznań with Volkswagen Poznań have launched a joint project for industrial heat recovery. Energy, heat from industrial processes, is used to supply more than 30 buildings in the district Wilda, including the HCP hospital in Poznań.
Thanks to our oil free screw compressors, which are necessary in the foundry of Volkswagen Poznań, this very energy-intensive process (up to 80% of the electricity consumed by the compressor goes into heat energy) is transformed to power the municipal heating system.

Certified oil-free air

Class 0 range of compressors, you are sure to be working with zero risk of contamination, unsafe products or losses from operational downtime.


Meets the top quality standard in the food & beverage industry

ISO 22000 certification for our oil-free production facility in Antwerp, Belgium. The food safety management system is applicable to all our Z type class 0 oil-free air compressors and related dryers and filters.

Energy savings up to 35%

Designed for high-efficiency. Save even more energy with our Variable Speed Drive (VSD), our energy recovery feature and energy-free MD dryers.

Fast & easy set-up

Plug-and-play packages with integrated dryers, VSD and energy recovery. Easy and low cost installation and a quick start-up guaranteed.

Optimal reliability

60 years of innovation and experience. Large installed base. Long lifetime through Atlas Copco designed and patented components:, stainless steel coolers, AGMA A5/DIN 5 gears and latest Inverter drive systems. Assured quality control by testing every unit.

Global presence – local service

Our aftermarket product portfolio is adapted to your needs, ensuring optimum availability and reliability of your compressed air equipment at the lowest possible operating costs.

Oil free screw compressor designed for energy efficiency

The components of the ZR/ZT oil free rotary screw air compressor range have been carefully designed in house. This reduces losses and pressure drop to a minimum, resulting in the highest compressor package efficiency. Our oil less compressors are also class 0 certified, delivering the highest air purity at the lowest total cost of ownership. By using our rotary screw technologies you are guaranteed to reliable and efficient compressor. 

Variable Speed Drive

Over 80% of a compressor's lifecycle cost is taken up by the energy it consumes. The generation of compressed air can account for more than 40% of a plant's total electricity bill. To cut your energy costs we've pioneered in Variable Speed Drive (VSD) Technology in the compressed air industry.

Atlas Copco's VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in energy savings of up to 35%.

Recover your energy

You can turn your compressor in an energy source. Our water cooled oil free air compressors can be equipped with an Energy Recovery unit. This will help you achieve your goals in becoming carbon neutral. Up to 94% of the electrical energy is converted into compression heat.

Without energy recovery, this heat is lost in the atmosphere via the cooling system and radiation. Our energy recovery unit uses the compression heat to heat up water. This warm water can be used for sanitary purposes, space heating or process applications.

Save energy with smart technology

Our compressor monitoring system saves energy by using advanced control algorithms. Our delayed second stop function uses air demand data to stop the compressor whenever possible. The dual pressure band can lower the pressure in your system during e.g. weekends and night shifts.

Our Elektronikon® controller is the brain of the compressor collecting data for optimal energy efficiency.

Monitor your system

It's important to know the status of your compressed air installation. With the Elektronikon® you can easily connect your controller with your mobile devices such as tablets and smartphones. Our SMARTLINK system allows mobile monitoring over a secure network. Monitoring your system not only saves you money, but also avoids breakdowns and production losses.

ZR and ZT oil-free compressors up close

With our global installed base, we can make 60 years of innovation and experience in oil-less air technology for you. No matter the conditions, our ZR and ZT produce certified oil-free air that protects all your critical processes and products. The difference? The ZR is water-cooled, the ZT is air-cooled. With pressure levels ranging from 3.5 up to 13 bar, we maximize your energy savings with a choice of rotary tooth or screw technologies.
