Hello guys i,v seen a few recovery machine models stating that their machines recycle refrigerant, and they have a oil drain tap on them,do they just seperate oil from the refrigerant and clean the gas, what i want to know is how do properly recycle refrigerant, i e if a burn out occures and you want to recycle the refrigerant to re use it again. or is it economical to build something my self to use for recycling . any ideas would be very grateful, thank you
