⚡ Field Charging & Handling Protocols
- Near-azeotropic blend: MUST charge as LIQUID from the cylinder liquid valve.
- Vapor charging will cause fractionation and degrade thermal capacity.
🔍 Leak Detection Protocols
- Electronic heated diode or infrared detectors
- Nitrogen pressure holding test at 400 PSI
♻️ Recovery & Legal Compliance
- Recover into DOT-4BA high-pressure cylinders rated for minimum 400 PSI working pressure.
