When you examine the graphics, you can see that the energy consumption of the pneumatic and servo-electric cylinders differs considerably, and that the energy consumption of the servo-motor system remains very low even without including the pneumatic equipment maintenance requirements (cylinder maintenance, valve, regulator, hose changes, conditioner, etc.). As the usage time increases, the difference between energy consumption becomes wider.

On the other hand, the first investment cost is also seen in the chart no. 2 besides the energy consumption. When we add the initial investment costs, it will be seen that the servo cylinder remains high (expected situation), but after 5200 hours of operation, the situation comes together and diverges sharply.
The servo electric cylinder will pay for itself in 1.5 years in a 3-shift working order.

Other Advantages of 100% Servo Controlled Machine

Apart from the basic cost advantages, the following benefits of servo systems are also
should not be overlooked:


  • No delays in welding speed caused by pneumatic cylinders.
  • Minimizing downtimes arising from possible malfunctions and instant maintenance requirements in multi-component pneumatic structure.
  • Elimination of the need to have a pressure tank, compressor, air system.
  • Elimination of force variability.
  • Elimination of the cost of the rangefinder and much more precise measurement. (More sensitive than incremental encoder.)
  • Providing shock-free and silent operation.

Carbon Emission and Carbon Footprint

Every method where efficiency is low and energy is obtained from fossil fuels increases the damage of the activity to the environment by increasing the emission of greenhouse gases, which are shown as the main responsible for global warming and measured in terms of carbon dioxide (CO2).


As can be seen from the graphics, traditional pneumatic systems have 2 main effects that increase carbon emissions:

      1. The high energy consumption of the system over the years.
      2. Cumulative energy consumption of the compressor system feeding the system and CO2 emission to the atmosphere.

In addition to the methodologies published by the Intergovernmental Panel on Climate Change (IPCC), GHG Protocol, ISO 14064, CDP, PAS 2050 are the leading standards that deal with the 6 main greenhouse gases (CO2, CH4, N2O, PFC, HFc, SF6) evaluated within the scope of the Kyoto Protocol. is coming.


Considering that 33.00% of the electrical energy in our country is obtained from natural gas, 30.00% from lignite and imported coal, and a significant share among renewable resources belongs to waste-garbage recycling, the effect of electricity supply on greenhouse gas emissions will be seen more clearly. (Figures are taken from TEİAŞ, EMRA, TSKB.)


In the carbon footprint calculation of institutions, which are classified as Scope 1-2-3, greenhouse gas emissions are tried to be reduced by obtaining even the energy used for heating and lighting from renewable sources, while servo systems with much lower energy consumption, no CO2 emission and much higher energy efficiency are used. will be an important step in both improving the carbon footprint and controlling the energy consumption of companies.


The use of these systems will become inevitable as carbon footprint standards become a legal requirement in the near future.
