F-Gas Information
From 1/1/2015, F-Gas Regulation EC 517/2014 came into force replacing the old Regulation EC 842/2006. This affects system
labelling, information supplied within documentation and also the way in which thresholds for frequency of leak testing
refrigeration systems are calculated. Please be aware of the following:
•
The models of equipment covered in this Technical Manual rely on fluorinated greenhouse gases for their functioning.
•
All unit models come from the factory pressurized with OFN (Oxygen Free Nitrogen) only.
•
The GWP (Global Warming Potential) values of refrigerants which are specified for use along with the three new
thres
holds for leak testing requirements based on TCO₂Eq (Tonnes CO₂ Equivalent) are as follows:
Refrigerant Charge - kg
5T 50T 500T
Refrigerant GWP CO₂Eq CO₂Eq CO₂Eq
R448A 1387 3.6 36.0 360
R449A 1397 3.6 35.8 358
•
Changes to leak testing requirements are as follows:
OLD LEGISLATION NEW LEGISLATION LEAK CHECKING FREQUENCY
3-30 kgs 5- 50 TCO₂Eq
Every 12 months but can be increased to 24 months if
fitted with a fixed leak detection system.
30-300 kgs 50- 500 TCO₂Eq
Every 6 months but can be increased to 12 months if
fitted with a fixed leak detection system.
300+ kgs 500+ TCO₂Eq
Every 6 months - however automatic leak detection
system is mandatory which requires servicing every 12
months
To calculate TCO₂Eq value: Refrigerant charge (kgs) x Refrigerant GWP
1000
Please note: From 1st January 2017, the new legislation applies to systems which previously were exempt from leak testing under
the ‘below 3kg’ charge limit.
A refrigerant charge label is supplied with each unit (inside the electrical box). The total refrigerant charge for the system and the
TCO₂Eq value must be entered on the label with indelible ink and must be adhered in the proximity of the product charging port.
The label supplied will represent the refrigerants approved for use with that particular unit. Examples of the unit labels are as
follows:
