Description
Euro R‑407C is a non‑ozone depleting alternative to HCFC‑22, designed to match its pressure-temperature behavior and cooling capacity in retrofit applications.
Key Features:
-
Zeotropic blend of ~23% R‑32, 25% R‑125, and 52% R‑134a
-
ODP = 0, ASHRAE safety class A1 (non-flammable, non-toxic)
-
Thermodynamics closely align to those of R‑22
-
Suitable for both new and retrofit systems designed around R‑22
Specifications:
| Property | Value |
|---|---|
| Composition | ~23% R‑32 / 25% R‑125 / 52% R‑134a |
| GWP | ~1,774 |
| ODP | 0 |
| Glide | ~3–5 K |
| Safety Class | A1 |
| Lubricant | POE only |
Applications:
-
Residential and commercial split systems
-
Central air conditioning, chillers, heat pumps
-
Medium-temperature refrigeration systems
Usage:
-
Remove all R‑22 and replace oil with POE before charging
-
Charge as liquid to maintain blend integrity
-
System design must account for temperature glide
FAQs:
-
Is Euro R‑407C a drop-in replacement for R‑22?
It requires retrofitting: full purging of R‑22, oil replacement, and charge adjustment. -
What does “glide” mean and why does it matter?
Glide is the temperature range during phase change; it impacts evaporator performance and must be considered in design. -
How does Euro R‑407C compare to R‑410A?
R‑410A operates at higher pressure and is more efficient—but is not suited for retrofits of R‑22 systems.
