Handling and Safety Information

  • Keep away from ignition sources and prevent static discharge.
  • Protect cylinders from damage and secure them upright.
  • Open valves slowly; close after each use and when the cylinder is empty.
  • Avoid inhaling high concentrations of vapor and prevent direct contact with liquid on skin or eyes.
  • Never apply heat or open flame to a cylinder.
  • Store cylinders in a cool, ventilated area away from direct sunlight or open flames.
  • Avoid areas near air conditioning intakes, boilers, and open drains.
  • Maintain storage temperature below 45°C to ensure product stability and safety.
  • Non-ozone depleting and environmentally safe
  • Reliable performance in low and medium temperature systems
  • Long-term replacement option for legacy refrigerants
  • Suitable for a wide range of commercial and transport refrigeration systems
