Frequently Asked Questions About Reclaiming Refrigerants

How do I recover refrigerant properly?

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.

Can I put ISCEON® MO99™ in the same recovery cylinder as R-22?

No. Do not mix different R-number refrigerants into the same recovery cylinder. By doing so, you will reduce the value of the recovered R-22.

Where can I return my recovered R-22 or other refrigerant?

Contact a DuPont Authorized Return Center in your area.

How do I know how much recovered refrigerant to put in my recovery cylinder?

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. Refer to the recovery cylinder manufacturer for your specific recovery cylinder fill weights, however, feel free to download our Recovery Cylinder Fill Weight Guide as a reference sheet.

How do I determine the correct pressure rated recovery cylinder to use?

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. Please download our Refrigerant Recovery Cylinder Guide.
