If you run a refrigeration service business, an appliance recycling facility, or an e-waste recycling plant, the refrigerant recovery equipment you use must meet specific EPA certification requirements. Under Section 608 of the Clean Air Act, recovery and recycling equipment must be tested and certified to ensure it can safely and effectively capture refrigerants before they are released into the atmosphere. Understanding these certifications matters both for staying compliant and for choosing equipment that actually performs.
What the EPA requires
EPA regulations under 40 CFR Part 82, Subpart F require that refrigerant recovery and recycling equipment be tested to verify it meets EPA requirements. For most equipment, these requirements are detailed in Appendix B2 to 40 CFR 82, Subpart F. Equipment manufactured or imported after January 1, 2017 must meet the stricter standards in Appendix B3 (for non-flammable refrigerants) or Appendix B4 (for flammable refrigerants). These standards are based on the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 740 test protocol.
AHRI 740 certification
AHRI 740 is the standard that defines the testing procedures recovery and recycling equipment must pass to receive EPA certification. Equipment is tested by an EPA-approved laboratory to verify it can achieve the required vacuum levels and recovery rates. Equipment manufactured after November 15, 1993 must meet stricter standards than older machines, including deeper vacuum requirements. When you buy a recovery machine, checking that it carries AHRI 740 certification is the first and most important step.
UL certification
Alongside AHRI, Underwriters Laboratories (UL) is another EPA-approved testing organization that certifies recycling and recovery equipment. Both organizations can provide information on certified equipment, so a machine certified by either AHRI or UL meets EPA's minimum requirements. Certified equipment can be identified by a label that states: "This equipment has been certified by AHRI/UL to meet EPA's minimum requirements for recycling and/or recovery equipment intended for use with [appropriate category of appliance]."
Standards vary by appliance type
Recovery equipment standards depend on the size and type of air-conditioning or refrigeration appliance being serviced. For example, small appliance recovery equipment must be able to recover either 90 percent of the refrigerant when the small appliance compressor is functional, or 80 percent of the refrigerant when the compressor is not functional. Equipment used with larger commercial systems must meet the evacuation levels specified in the EPA's required evacuation tables. This is why a single machine is not always suitable for every job, and why matching the certified equipment to your application matters.
A practical checklist for buyers
When evaluating refrigerant recovery equipment, use this checklist to confirm EPA compliance and reliable performance:
- Look for the AHRI or UL certification label on the machine itself.
- Confirm the equipment is compatible with the refrigerants you handle, such as R134A, R404A, R407C, R410A and similar common blends.
- Check the recovery rate in both liquid and vapor modes, since slow recovery ties up your technicians and your jobs.
- Verify that the machine's collection tank and recovery cylinders meet DOT requirements, including the 80 percent fill rule and hydrostatic retest dates.
- If you work with newer flammable refrigerants such as A2L blends, choose equipment rated for those refrigerants.
Choosing certified refrigerant recycling equipment
For appliance recycling plants and e-waste recyclers, refrigerant recovery is only one step in a complete end-of-life treatment line. San Lan Technologies Co., Ltd, a professional manufacturer of WEEE and e-waste recycling machinery, offers a range of refrigerator and AC recycling machines designed for this work. Their refrigerant extraction machine SD-680 features a dual input design, multi-stage filtration, oil separation and air separation, and is compatible with R404A, R407C, R410A and R134A refrigerants, with a recovery rate of 50 kg/h for liquid and 25 kg/h for gas. The refrigerant recycling machine RRM-650 is another option for recovering refrigerant from AC and refrigerator compressors. For the complete treatment line, an AC compressor cutting machine separates the compressor shell so the copper coil can be recovered after the refrigerant has been extracted.
Buying certified refrigerant recovery equipment is not just a paperwork exercise. It protects the environment, keeps your operation compliant with EPA Section 608 rules, and ensures your machines actually capture the refrigerant they are supposed to capture. Start with the certification label, match the equipment to your refrigerants and appliance types, and build the rest of your recycling line around machines designed to work together.
