R134a replacement help

[Bill]

I have a technical consulting company & have a client who needs to replace r134a with a EU friendly refrigerant. Currently the gas is vented to atmosphere. I'm looking for a consultant to help guide them. Please let me know if anyone wants to discuss or recommend someone. Thanks.

What do you consider 'EU Friendly?' There are no restrictions on R134a, except in cars.


Currently the gas is vented to atmosphere.



That's as illegal in the EU as it probably is in the States.


Please let me know if anyone wants to discuss or recommend someone. Thanks.

Can you be more specific?

thanks for reply. My client states it (r134a) may be banned in the future & wants to design his product accordingly. Specifically wants to examine other gasses & mixtures that could be used in their system, report on required pressures, toxicity, flammability, and compatability with EU standards (now & anticipated). My client (nor I) is not a refrigerant expert thus an initial consult to establish the "starting point" may be appropriate.

Please let me know if you would like to discuss furhter.

thanks again,

bill

Bill,

Are you talking about the EU or elsewhere?

What sort of equipment?

If you are considering drop-in replacements, be careful. It is not permitted to drop Hydrocarbons into existing HFC equipment; electrical equipment, oils and other materials may not be compatible, plus there are containment limits in force for flammable substances.

There is currently new legislation in preparation in the EU (Check today’s new post in the Legal section), but, unless you are thinking of mobile A/C (cars etc), there are no plans to ban R 134a in the EU. Some states (Austria and Denmark) have already done so prior to the new laws, but they were challenged in the EU courts and a compromise derogation in the new regulation allows them to continue these practices up to 2012, but not to introduce new ones and precludes other member states from doing likewise.

It's a medical device product, which I suspect is a stand-alone unit & not a replacement. I'll share your comments with my client for a response. Should it makew sense, would you be interested in discussing the points you made with my client?

Thanks again
