EPA 608 Refrigerant Recovery, Recycling & Reclamation

Question 1

What is the primary difference between refrigerant recycling and reclamation?

Accepted Answer

Recycling is done on-site and reused by the same owner; reclamation is done at an EPA-certified facility to meet ARI 700 standards

Answer

Recycling cleans refrigerant on-site for reuse in the same or similar equipment owned by the same customer, while reclamation is performed at an EPA-certified facility to meet ARI 700 purity standards before resale.

Question 2

What is the primary goal of refrigerant recovery under EPA Section 608?

Accepted Answer

To remove refrigerant from a system and store it without releasing it into the atmosphere

Answer

Recovery captures refrigerant from a system and stores it in an approved cylinder to prevent atmospheric release, as required by the Clean Air Act.

Question 3

Which type of recovery equipment does NOT have its own compressor and instead relies on the system being serviced?

Accepted Answer

System-dependent (passive) recovery unit

Answer

System-dependent recovery equipment has no internal compressor and relies on the system's own compressor or pressure to move refrigerant into the recovery cylinder.

Question 4

For a small appliance (Type I) with a functional compressor, what is the minimum refrigerant recovery efficiency required by EPA 608?

Accepted Answer

90%

Answer

EPA 608 requires 90% recovery efficiency for small appliances containing 5 lbs or less of refrigerant when the system compressor is operational.

Question 5

What is the required color coding for DOT-approved refrigerant recovery cylinders?

Accepted Answer

Gray body with a yellow top

Answer

DOT-approved refrigerant recovery cylinders must be gray with a yellow top to distinguish them from other compressed gas cylinders and ensure safe identification.
