5. Portable Recovery & Recycling Machine

Definition

“Recovery” means To remove refrigerant in any conditions from the system and store it in an external container.

“Recycling” means The process of reducing contaminations in refrigerant recovered from the system by oil separation, non-condensable removal and core filter-driers which will result in reduction of moistures, acidities, and particular matter.
