F-GAS INSPECTIONS / F-GAS REGISTERS
Since July 2007, regulation EC No 842/2006 has stipulated rules for systems containing more than 3kg of hydrofluorocarbons (HFCs, or F-Gases). These rules are mainly intended to prevent leaks, as the gases can have a powerful greenhouse effect.
The most damaging F-Gases will be phased out over the next few years, but certified personnel will still be required for regular checks. Operators are required to take all ‘technically feasible’ steps to prevent leakage and repair leakage.
The volume of refrigerant in your system determines how often tests must be carried out, with annual tests the absolute minimum. Frequency is determined as follows:
- 3kg to 30kg: every 12 months;
- 30kg to 300kg: every six months, or every 12 months if a leak detection system is installed;
- 300kg or more: every six months. Technically the rules stipulate every three months, but leak detection systems are mandatory at this level, and these systems halve the required frequency.
If a leak is identified, the system must be rechecked within a month of the repair.
