Suggested measures
energy efficiency

In order to identify solutions to reduce consumption and energy costs, our specialists have carried out various industrial energy audits aimed at installations with the highest energy efficiency potential. Following the performance of complex measurements/calculations/analyses in the key points of the distribution and consumption system, the identified solutions were embodied in the Plan of measures and actions for increasing energy efficiency. The companies that created and implemented such plans are:

Thermal energy audit

Benefit from a broad, clear and realistic "radiography" of energy consumption

Complex energy audit

Benefits of complex energy audit

  • The analysis of energy balances will lead to: locating energy losses, determining their causes and classifying them, as well as establishing the measures that must be applied to optimize the technical-economic indicators
  • The analysis will highlight all reusable energy resources, highlighting them by category and energy potential
  • The central objective of the energy audit is to substantiate and quantify, through cost-benefit analysis, feasible solutions to increase energy efficiency

Industrial compressed air audit

Benefits of industrial compressed air audit:

  • 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


The correct application of procedures for increasing energy efficiency implies in-depth knowledge of the specifics of the activity carried out in an established outline. In this sense, for the precise determination of energy flows entering and exiting a given contour, the latest portable measuring and data acquisition equipment are used. These high-performance equipment offer the possibility of performing a qualitative and quantitative analysis of the energy supply of the activities carried out in an outline and, respectively, provide effective information with the role of identifying, locating and preventing problems in energy installations.
