🚀 Key Features & Benefits

True Drop-In Retrofit for R‑22:

Delivers similar capacity and often improved efficiency, without requiring component changes like compressors or expansion valves

Lower Discharge Temperatures:

Up to 40 °F cooler discharge temperatures enhance compressor reliability

Oil Compatibility:

Runs on POE oil; existing mineral oil or alkylbenzene often acceptable if an oil separator is present—typically only one oil conversion needed

Minimizes Workloads:

Charging as a liquid prevents fractionation; systems often require only vacuum, oil checks, and recharge—no other hardware changes

💼 Applications & Use Cases

Ideal for retrofitting or servicing:

Low- and medium-temperature refrigeration units (walk-ins, freezers, transport)

AC systems: rooftops, split systems, chillers, heat pumps

Industrial and commercial HVAC/R platforms previously using R‑22
