Low-pressure refrigerant — boils near 75°F at atmospheric pressure, so most of the operating range sits in vacuum.
″ vac = inches of mercury vacuum (below atmospheric pressure).
Reference values only — verify against the manufacturer's PT card and your gauge set.
03Supply
Buy R-11
We supply reclaimed R-11 tested to AHRI Standard 700. The production phaseout does not prohibit use of lawfully held pre-ban inventory.
Every reclaimed batch we ship is tested in our laboratory against AHRI Standard 700. Confirm equipment compatibility and application requirements when ordering. No prices are published: refrigerant markets move weekly, so every order is quoted on current supply.
// Every {designation} order
- Reclaimed batches verified to AHRI-700 before shipment
- Quoted by cylinder size and current market — no published price lists
- Will-call in Santa Fe Springs or delivery across Southern California
04Buyback
Sell us your R-11
Priority buy. Scarce CFC feedstock, typically recovered from low-pressure centrifugal chiller retirements — large charges welcome.
We supply DOT recovery cylinders and shipping documents, or pick up across Southern California. On receipt, every load gets a certified scale weight and AHRI-700 laboratory analysis, and a Recovery Manifest documents chain of custody for your EPA records.

Final price based on certified scale weight and AHRI-700 lab analysis on receipt.
05Regulatory status
Where R-11 stands
CFC (Class I ODS)
New production has been banned since 1996 under the Montreal Protocol CFC phaseout. Supply includes reclaimed refrigerant and pre-ban inventory. Servicing existing R-11 equipment remains legal.
