Recovery, Recycling, and Reclaiming Flashcards

What is the key difference between recycling and reclaiming refrigerant?

Answer: Reclaiming processes refrigerant to ARI-700 purity and requires chemical analysis; recycling only reduces contaminants on-site

Reclaiming restores refrigerant to ARI-700 (AHRI-700) purity with a chemical analysis, while recycling merely reduces contaminants through filtration on-site.

Recovered refrigerant may be returned to the same system or a system owned by the same owner without reclamation when it is only:

Answer: Recycled or recovered

Refrigerant that is recovered or recycled may be returned to the same or another system owned by the same person without being reclaimed.

Before refrigerant can be sold to a different owner, it must be:

Answer: Reclaimed to ARI-700 standards

Refrigerant changing ownership must be reclaimed to ARI-700 purity by a certified reclaimer before resale.

A recovery cylinder should never be filled beyond what percentage of its capacity?

Answer: 80%

Recovery cylinders must not be filled beyond 80% of capacity to allow room for liquid expansion and prevent rupture.

What color combination identifies a DOT-approved refrigerant recovery cylinder?

Answer: Gray body with yellow top

Recovery cylinders are marked with a gray body and yellow top to distinguish them from disposable refrigerant cylinders.

Recovery cylinders must be hydrostatically tested and re-marked at least every:

Answer: 5 years

DOT requires refillable recovery cylinders to be hydrostatically retested every 5 years.

Mixing two different refrigerants in one recovery cylinder results in:

Answer: A cross-contaminated mixture that usually must be destroyed

Mixed refrigerants cannot be separated economically and typically must be sent for destruction, so cylinders should hold only one refrigerant type.
