Refer to our Safe Recovery Procedures, which includes: 10-step process, personal safety guide, fill weight guide, and a listing of the proper pressure-rated cylinder to use by refrigerant. Also refer to Steps to Proper Refrigerant Recovery.
No. Do not mix different R-number refrigerants into the same recovery cylinder. By doing so, you will cross-contaminate the refrigerant and in most cases, end up with a charge to dispose of the mixed gas.
Contact a Chemours Authorized Return Center in your area who accepts used refrigerant returns, in most cases has small cylinder exchanges--empty for full--and will properly handle and return the cylinder to an EPA-certified reclaim provider.
Liquid refrigerant will expand as its temperature is increased. If the cylinder somehow becomes completely full of liquid, the pressure can increase dramatically with a relatively small increase in temperature. Typically, the cylinder should not be filled to more than 80% liquid full at 77°F (25°C). Refer to the recovery cylinder manufacturer for your specific recovery cylinder fill weights.
It’s very important to use the proper pressure-rated (psi) recovery cylinder for the refrigerant you are recovering from your system. The cylinder size also plays a role to determine the correct psi cylinder.
EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act restrict the resale of used refrigerant to a new owner unless it has been reclaimed to at least the purity specifications (AHRI Std 700) by an EPA-certified refrigerant reclaimer. Refrigerant that has been recovered and/or recycled can be returned to the same system or other systems owned by the same person without being reclaimed.
