Inspection of HVAC industrial ventilation systems

Cleaning up workplaces in industrial environments is a priority for occupational and environmental health in order to avoid exposure of the population to dangerous substances. The development of ventilation, filtration, pollutant capture and containment systems is becoming increasingly sophisticated, depending on the pollutants emitted. 
And in a context of rising energy costs and reduced greenhouse gas emissions, improving the energy performance of buildings is a major challenge.
Eurocontrol is monitoring all these developments to ensure quality controls and to protect health risks in the workplace.

What is the

inspection of ventilation and air treatment?

The inspection of ventilation and air treatment (HVAC) systems in industrial installations guarantees that they adequately fulfil the safety functions for which they were designed and that there are no degradation processes that prevent the satisfactory fulfilment of these functions.


At Eurocontrol we test ventilation and air treatment (HVAC) systems in industrial installations, in accordance with the requirements established in the applicable reference standards (UNE-EN-ISO 14644, ASME AG-1, SMACNA-HVAC System Testing, ACGIH, etc.).

We have qualified inspectors according to UNE 73 405:2001 and ANSI/AMSE N45.2.6-1978.

We have specific equipment to carry out all types of tests required in filtration and ventilation systems:

  • Multifunction portable equipment.
  • Hot wire anemometers, windlass anemometers and Pitot tubes.
  • PAO aerosol detector photometer, Model TDA 2iN by ATI.
  • Hot aerosol generator Model TDA 5C from ATI.
  • Precision digital manometer for absolute pressure measurement.
  • Precision digital micromanometer for relative pressure measurement.

Industrial Hygiene

Countless studies have been able to demonstrate the cause-effect relationship between certain jobs and the development of certain diseases. Most of these diseases do not show obvious symptoms until after a long time, even years. It is therefore essential to approach the problem from a preventive point of view, as this is the only way to achieve an optimal state of health for the worker at the end of his or her working life. Industrial hygiene is one of the tools we can use to achieve this goal.
