Recovery
means to
collect the refrigerant in a
special holding container.
Recycling
means to run the
refrigerant through
a filtering system to remove most particles and moisture.
Reclaiming
means to
chemically reprocess t
he refrigerant to return it to its original purity.
Recovering and recycling
refrigerant is possible with the aid of mechanical devices made for the
purpose .The recovery system is a compressor
/
pump assembly, which removes refrigerant from
a
system and safely stores it in a
