Decarbonisation Through Green Automation

Climate Protection & Greenhouse Gas Neutrality

With the amendment of the Climate Protection Act, the European Government has anchored the goal of greenhouse gas neutrality by 2050. The European Commission adopted a set of proposals to make the EU's climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels.

In view of the scarcity of all resources and the increasing importance of energy efficiency, the sustainability goal of green automation is more topical than ever. This also includes the environmentally friendly design of production processes as well as resource-saving technologies such as robotics and automation solutions.


Reduce energy consumption sustainably

Using energy in drive technology much more efficiently than in the past is an important goal for sustainable development in many manufacturing companies. This involves their future development and measures to effectively counter the growing cost pressure.

The key to reducing production costs lies in eliminating performance losses in the energy-intensive overall processes of factory automation. This is why more and more companies are opting for airless automation and replacing their pneumatic cylinders with electric ones.



Green Automation by IAI


IAI defined the efficient use of energy as one of its corporate goals as early as 2008. All measures are summarised under the term "Green Automation".

The efficient use of energy is viewed holistically. IAI actuators are to be manufactured with as little energy input as possible. At the same time, the airless drive solutions help to minimise energy consumption on the customer's side as well.

Comparison:   Energy consumption IAI electric actuator and pneumatic cylinder

The generation and distribution of the compressed air required for the operation of pneumatic cylinders is associated with very high losses that can only be optimised to a limited extent. In addition, the energy requirement of a pneumatic cylinder increases sharply compared to electric cylinders when the utilisation of the production plant and thus the cycle frequency increases. The difference in energy consumption increases with the number of work cycles per minute.

Power consumption at different utilisation rates

In the practical test, the power consumption of an electric cylinder is compared with a pneumatic one at a load of 10, 20 and 30 %. Both actuators operate for one hour each under the same production conditions:

Electric Actuator (EC-S6H) Pneumatic Cylinder: Ø 25
  • Stroke: 300 mm
  • Payload: 12 kg
  • Speed: 375 mm/s
  • Duration: 0,3 G
  • Duration: 1 h
  • Travel time: 1 s
  • Stroke: 300 mm
  • Payload: 12 kg
  • Speed: 320 mm/s
  • Air pressure: 0,4 MPa
  • Duration: 1 h
  • Travel time: 1 s

Reduction:  Annual energy costs and CO2 emissions

The difference in energy consumption between EleCylinder and pneumatic cylinders depends on their frequency of use. The more often pneumatic cylinders are replaced by electric cylinders, the higher the energy savings.

The example shows the energy costs and CO2 emissions of a production line with 300 actuator each.


Sustainability:  No sealing materials - long service life

The sliding components on the EleCylinder do not require sealing materials. Instead of damping devices, the integrated linerar guide of the EleCylinder is equipped with a recirculating ball screw and ball guide track.

Based on internal calculations, the service life of an EleCylinder is five times longer than that of a pneumatic cylinder.
