Description
Refron R‑407C is an HFC blend of R‑32, R‑125, and R‑134a, used as a replacement for R‑22 in air conditioning and commercial cooling applications. It offers close thermodynamic properties to R‑22 without ozone depletion.
Key Features:
-
Zero ozone depletion
-
Close match to R‑22 system performance
-
Efficient in cooling and heat pump systems
-
Economical alternative for retrofits
-
ASHRAE A1 safety classification

FAQs:
Q1. Can R‑407C be used directly in R‑22 systems?
Not directly. The system must be retrofitted, and oil replaced.
Q2. What are the downsides of R‑407C?
It has glide, which means the temperature changes during phase change – requiring careful system design.
Q3. Is R‑407C better than R‑410A?
Not necessarily. R‑410A is more efficient but requires a higher pressure system. R‑407C is used in R‑22 retrofit cases.
