Sealed System
Definitions
Recovery:
To remove refrigerant in any condition from a system
and store it in an external container without necessarily
testing or processing it in any way.
Recycling:
To clean refrigerant for reuse by oil separation and sin-
gle or multiple passes through devices, such as replace-
able core filter-driers, which reduce moisture, acidity and
particulate matter. This term usually applies to
procedures implemented at the field job site or at a
local service shop.
Reclaim:
To reprocess refrigerant to new product specifications
by means which may include distillation, will require
chemical analysis of the refrigerant to determine that
appropriate product specifications are met. This term
usually implies the use of processes or procedures
available only at a reprocessing or manufacturing facility.
