flamability.

Hi sirs.
how about flamability of MO49 and MP39 in compare with R12?
we may use them in some tran-passenger air- conditioners and need to have doccuments for approval.

Hi there,

have a look at :

http://www.refrigerants.dupont.com/Suva/en_US/products/suvamp39.html

It might help.

Also I suggest you contact the refrigerant supplier for better info.

Cheers

If by "trans-passenger" you mean air transport then you will need to type approval from the aircraft manufacturer to enable compliance.

The refrigerant manufacturer does not provide compliance for use in aircraft.

I think he means Trains.

CheersThat's OK then, cheers.

[pirestani]

ok.
excuse me for wrong dictation ,I mean train-passenger air conditioner .
"depont" has no information about R12 to compare with any other.looking for safe side of MO49 or MP39 in this case.

Dear pirestani,

As far as I know there is a charge limit for the refrigerants which are flammable.
This means that for every application there is a charge limit for safety reasons.

You can get the best and reliable info from the manufacturer.

What about retrofiting to R-134a?

[pirestani]

Yes we have tried R134.but since we still have some old system(out of work and recently are beeing recharged) which have been charged with R12, as the last decision to avoid changing oils(MO or POE) and protecting of acidic oil hazards it was prefered to use some "drop in" refrigerants.
Anyway thanks for ur attention .
