Applications
Mainly used as a refrigerant in room A/C, commercial refrigeration, cold-chain and heat-pump systems.
Safety & storage
Store in a cool, dry, well-ventilated place away from heat and open flame; keep cylinders upright and secured against rolling or impact. Although non-flammable, avoid high temperature that raises cylinder pressure.
