Recovery & RecyclingCâu 232 / 240

Why is identifying the refrigerant before recovery especially important today?

a.Mixed charges can't be reclaimed
b.Because all refrigerants are now identical
c.Because it changes the cylinder color
d.Because it lowers recovery pressure

Giải thích

With many refrigerants in the field and counterfeit or mixed charges circulating, identifying refrigerant first protects your recovery machine and cylinder from contamination and preserves the refrigerant's value for reclamation. A mixed batch usually cannot be reclaimed and must be destroyed. A refrigerant identifier is a small investment against a costly mistake.
