Product details
R-513A is the lower-GWP stand-in for R-134a, and it is an azeotrope — which in practice means it behaves much like a single compound in service, with effectively no temperature glide to complicate superheat and subcooling. That makes it one of the more comfortable transitions available as the phase-down tightens.
Supplied in a 30 lb cylinder. Check lubricant compatibility for the specific equipment before a changeover; a low-GWP swap is still a refrigerant change, and the system's oil and seals get a say.
Highlights
- 30 lb cylinder
- Lower-GWP replacement for R-134a
