The refrigerant circuit has many points where it is necessary to use brazing filler material.
In addition to the traditional materials for Fe/Fe, Fe/Cu coupling with silver-based alloys (typically T90S a 40% Ag with Sn) and Cu/Cu coupling with (with CuP alloys with Ag such as FH45, FH46 or FH35) it is possible to use a unique brass alloy of the MR series with the ECOFLUX® liquid flux (instead of traditional liquid fluxes which are toxic).
