- R-407C is a hydrofluorocarbon (HFC) alternative for R-22 in positive displacement air-conditioning (AC) equipment
- R-407C can also be used in many medium-temperature refrigeration systems that formerly used R-22.
- Work in existing medium-temperature applications
- Work in new or existing residential and commercial AC and heat pumps
- Replacing R-22 with Freon™ 407C in these systems requires switching to polyolester (POE) oil.
- Similar cooling capacity, energy efficiency, and pressures as R-22 in systems
- An ability to be topped off after a leak, multiple times, with minimal impact on system performance
