r500 aircon alternative refrigerant

[Argus]

R 409B is a ternary blend of 3 HCFCs. It is restricted in the EU under article 5 of Regulation 2037/2000 (the ODS REgulations).
You can still use it as a replaceent (subject to the phase-out rules), but don't expect any discounts on HCFCs. I expect the price of all HCFCs and thier blends will go through the roof.

My opinion is that anyone converting to these (in the UK) will need their head reading.

Evidently Australia has different rules for chlorinated gasses and blends.
..... no doubt some of our friends down under will tell us what the state of play is with them.
