Refrigerants are chemical compounds widely used in various cooling, air conditioning, and refrigeration systems. They transfer heat and enable cold storage of food, space cooling, and industrial processes.
However, many traditional refrigerants, especially HFC compounds, are potent greenhouse gases with high climate impact. Therefore, their use is increasingly regulated under the EU F-gas Regulation (517/2014).
Stricter requirements in 2025
The regulatory updates that came into force in 2025 further restrict the use of refrigerants with high Global Warming Potential (GWP). This especially affects systems using refrigerants such as R134a, R22, R404A, R507, and R410A.
The availability of these substances within the EU is governed by a quota system, in which the total allowable amount on the market decreases each year. Manufacturers and importers must purchase emission allowances (quotas), which are limited in supply. This increases the prices of refrigerants and may lead to supply shortages.
From the beginning of 2025, the use of new high-GWP refrigerants for servicing is only allowed in recycled or reclaimed form — and only for a limited transition period. This directly impacts service procedures, equipment choices, and the lifecycle management of entire cooling systems.
Leak detection becomes critical
As regulations tighten, leak prevention and monitoring become even more important. The EU regulation requires that refrigerant systems be equipped with proactive monitoring to detect leaks as early as possible.
Detector’s gas detectors provide a reliable and certified solution for refrigerant leak detection. The systems are particularly suitable for facilities using HFC-based refrigerants, such as:
• Cold rooms and freezer warehouses
• Retail freezer cabinets
• Industrial refrigeration and process systems
• Commercial and institutional kitchen refrigeration systems
Reliable leak detection helps comply with regulations, reduces environmental impact, and prevents costly downtime or spoilage. It also improves safety for property users and those responsible for the facilities.
