🔧 Performance Highlights

Closely mimics R‑22’s pressure‑temperature profile—ideal for retrofit applications

Slightly lower discharge temperatures improve compressor longevity

Compatible only with POE (polyol ester) oils; not miscible with mineral oil

Liquid-phase charging is essential to prevent blend fractionation due to temperature glide

🛠️ Applications & Best Practices

Designed for air conditioning & heat pump systems originally using R‑22

Used effectively in medium-temperature HVAC/R systems, chillers, rooftops

Requires full mineral oil flush and conversion to POE oil for retrofitting

Leak-down requires recover & recharge to maintain correct composition

🔧 Handling & Safety Guidelines

Store cylinders upright in cool, ventilated areas away from heat sources

Use standard PPE; avoid direct contact (risk of frostbite)

Decomposition at ≥250 °C may generate toxic byproducts (HF, carbonyl halides)

Comply with refrigerant recovery regulations (EPA Section 608, EU F‑Gas regs)

📦 Packaging Options

Typically available in 25 lb (11 kg) cylinders with dual ports; other sizes available via Climalife, Gas‑Servei, A‑Gas, Linde, Chemours.
