“Freon” is a popular brand name used to describe chemical refrigerants. In the compressed air industry, these gases are vital for running refrigerated air dryers. However, due to their environmental impact, global and national laws are rapidly phasing them out.
If your facility operates older air dryers, understanding South African refrigerant legislation is critical to avoiding service disruptions and planning equipment upgrades.
The Legal Framework: Why is Freon Regulated?
South African refrigerant laws are governed by the Department of Forestry, Fisheries and the Environment (DFFE) under the National Environmental Management: Air Quality Act. These laws align with two major international treaties:
- The Montreal Protocol: Focuses on eliminating Ozone-Depleting Substances (ODS) like older CFCs and HCFCs.
- The Kigali Amendment: Focuses on phasing down Hydrofluorocarbons (HFCs) because of their high Global Warming Potential (GWP).
The Phase-Out Timeline Impacting Your Air Dryers
1. The R22 (HCFC) Phase-Out: Happening Now
R22 (often called R22 Freon) was the standard gas for older air dryers. Because it damages the ozone layer, its import is being aggressively restricted.
- The 2026 Quota Cut: South Africa’s legal import quota for virgin R22 has dropped to just 2.5% of its original baseline.
- The 2030 Ban: By 2030, the import and production of virgin HCFCs will be entirely banned.
- What this means for you: Virgin R22 is becoming incredibly scarce and expensive. If your air dryer leaks or breaks down, it will become increasingly difficult and costly to service unless you switch to reclaimed gas or retrofit the system.
2. The HFC Phase-Down: The Next Phase
Common replacement gases like R134a and R404A do not damage the ozone layer, but they are powerful greenhouse gases. South Africa has committed to a strict HFC phasedown schedule, beginning with a 10% import cap reduction in 2029 and leading to an 80% total reduction by 2045.
