Freon™ 407C (R-407C)

Among the options offered in the Freon™ refrigerant portfolio, Freon™ 407C (R-407C) is a high-performance blend. This alternative to R-22 in positive displacement air conditioning (AC) equipment can also:
* Replace R-502 in new and retrofitted medium-temperature applications with evaporator temperatures above -6.7 °CC (20 °F).
* 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. 

Features and Benefits
Freon™ 407C has been a popular R-22 replacement because of its properties, which include:
* 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.
* Safety; Freon™ 407C has an ASHRAE A1 safety classification.
