Does any one have any information / experience on retrofitting a large pumped liquid R22 system, (5000kg) with R507?

Hi Country boy,

I could send you a report on a hypermarket retrofit from R22 to R404A, which is "the same" thing than R507.
Should you like to have it, please ask.
The retrofit was carried out in 14hours, cleaning the circuits and extracting all MO.
R22 was recycled for its later reuse, regarding E.R.1005/2009.

Regards,

Nando.
