Appraisal of energy use levels in
industrial compressed air installations

Most of the times, the energy audit for industrial compressed air is ignored, although it represents one of the greatest opportunities to reduce energy consumption in industry.

Industrial compressed air is considered the fourth utility and has direct effects on energy consumption, being the most expensive utility used in the manufacturing industry.

Successful projects

Identifying the points where it is possible to intervene to reduce costs and increase loading safety

Radiography and analysis of industrial compressed air installations

Highlighting the investment costs of the proposed improvement measures and calculations related to their recovery period

Industrial compressed air installations energy audit

Profitable energy efficiency

In order to eliminate the significant wastage from industrial compressed air installations and to optimize the energy consumption, the following major elements are analyzed in detail:

- Production of compressed air
- Distribution of compressed air
- Use of compressed air


The audit performed by Quartz Matrix SRL is in accordance with the requirements of the Energy Efficiency Law no. 121 of 18.07.2014 and completed with Law 160 of 26.07.2016, adopted by the Romanian Parliament. This law transposes Directive 2012/27 / EU of the European Parliament and of the Council of 25 October 2012 on energy efficiency, amending Directives 2009/125 / EC and 2010/30 / EU and repealing Directives 2004/8 / EC and 2006 / 32 / EC, published in the Official Journal of the European Union series L no. 315 of November 14, 2012.

Good to know!

Interrupting a factory's industrial compressed air supply can have negative effects, as bad as a power outage. Therefore, the main requirement for modern compressed air installations is continuous availability.
As energy and maintenance costs represent approximately 80% of the total operating costs of the compressed air system, it is important to pay special attention to analysis, planning and acquisition. The direct benefit will be reflected later in the energy bill.
The audit involves taking into account a wide variety of system elements and selecting the optimal combination of components corresponding to each industrial compressed air installation. No two systems are the same and each is designed to meet customer’s requirements.
Whether a new system is installed or an existing one is checked, it is necessary to determine the demand for industrial compressed air. The audit not only ensures data collection, but also records the variable loading periods to verify the sizing of the compressors and the interaction between them during operation. Thus, an overview is created on the compressed air system that takes into account the number of compressors, their type, type of cooling, the size of the buffer vessels, the air treatment and the diameter of the pipes.
The air treatment system must be efficient, with minimal pressure losses and be able to meet the demands of operation at both maximum and partial load.
