The importance of hiring a licensed refrigeration technician to maintain refrigeration equipment and check it for leaks cannot be overstated, especially in view of Article 33 of the Regulation of the Republic of Serbia on handling substances that deplete the ozone layer.



The regulation requires regular inspection and maintenance of refrigeration systems to prevent leaks of harmful substances, such as refrigerants, which can seriously damage the ozone layer and contribute to global warming.
01How often must equipment be checked?
Under the regulation on periodic inspection, equipment containing:
- 3 kg or more of controlled substances must be checked at least once every 12 months – except hermetically sealed systems that contain controlled substances used as refrigerants, are labelled as such, and contain less than 6 kg of controlled substances;
- 30 kg or more of controlled substances must be checked at least once every six months;
- 300 kg or more of controlled substances must be checked at least once every three months.
02Why a licensed technician?
Hiring an expert licensed in refrigeration ensures that this equipment is carefully inspected, maintained and repaired to the highest technical and safety standards. These technicians are trained to recognise and diagnose potential problems and to resolve them properly, preventing serious breakdowns, unnecessary costs and possible environmental incidents.
Refrigeration technicians are also familiar with the procedures and regulations governing the safe handling and removal of harmful substances, which helps protect the environment and reduce the negative impact on the ozone layer. They also advise on more efficient energy use and ways to improve equipment performance.

In addition, licensed refrigeration technicians issue a special leak test certificate in line with the mandatory testing schedule, providing further assurance of the safety and soundness of refrigeration systems.
Working with these experts therefore not only meets the legal obligation to check refrigeration equipment for leaks, but also provides safety, reliability and protection for your equipment, the environment and the community as a whole. Hiring them is key to preserving the ozone layer, protecting the environment and creating a more sustainable world for all of us.
So that each of us can contribute to preserving the environment for future generations, it is important to look after refrigeration dryers and chillers in good time and prevent potential leaks of greenhouse gases.
