Even though the air can be found around us without any problem and completely free of charge, its use in the industry is a problem, if we talk about energy. From a simple tool running on air, to the most complex machine. A large number of devices, surround the industry with their air-filled pipes.
According to a recent study by the U.S. Department of Energy, in a typical industrial facility, approximately 10% of the electricity consumed is consumed for the generation of compressed air, and may even exceed 30%.
The existence of 4 industrial revolutions is widely accepted. Each of these revolutions is determined by inventions and novelties that after being introduced in the factories, they greatly improved the production efficiency.
The 4 industrial revolutions and the main changes in the industry:
1st Industrial Revolution (1784) – Mechanization: steam machine, water power and mechanization.
2nd Industrial Revolution (1870) – Electricity: mass production, assembly line and electricity.
3rd Industrial Revolution (1969) – Computing: Automation, technologies of the information and communication (TIC)
4th Industrial Revolution (today) – Digitalization: Internet of things, clouding, digital coordination, cyber physical systems and r...
Spanish industrial companies are clearly behind those of the rest of the world in terms of digitalization, as revealed by the report "Industry 4.0", prepared by the consultancy PwC from interviews with 2,000 managers of companies in the sector in 26 countries -45 of them Spanish ones-. If at a global level the companies of the industrial sector have gone from words to action, in our country we are still not in this scenario.
The report concludes that only 8% of Spanish industrial companies - auto, aerospace, electronics, chemicals, paper, metallurgical, construction and transport and logistics - are at an advanced level of digitization, 25 points below the global average, which stands at 33%.
