Kryon® 422B is an easy-to-use and non-ozone depleting HFC refrigerant. Developed to replace R-22 used in residential air conditioning.

GeneralGas KryoSmart cylinders are manufactured in full compliance with the European T-PED regulation and are refillable an infinite number of times.
GeneralGas provides an effective refill service for the empty container and subsequent return to the customer, in full compliance with the requirements of European regulation No. 517/2014. The refilling of empty containers, returned by the customer, is carried out at the GeneralGas factory in Cernusco sul Naviglio (MI) - Italy.


  • Kryon® 422B allows easy, fast and favourable conversion.
  • It allows the continuous use of existing plants.
  • A lower delivery temperature compared to R-22.
  • It is possible to fill the system up during the service, without having to remove the whole refrigerant charge.

Recommended Lubricants

Kryon® 422B is compatible with new and traditional lubricants (mineral oil, alkylbenzene or polyester). 
Most of the time changing the lubricant during the conversion is not necessary.


KryoSmart Cylinders with a small amount of refrigerant charge

In the field of automotive, the use of cylinders with a small capacity is very useful when refilling connecting pipes or conditioners. The advantage consists in marketing a cylinder that has a low market value, and therefore it is easier to sell it. Our KryoSmart® Cylinders are available 1 Litre size (in pack of 12 picies) and in 2,5 Litre size (in pack of 6 picies). KryoSmart® Cylinders are made of low carbon steel with a maximum working pressure equal to 48 bar. KryoSmart® Cylinders are filled by General Gas with the use of a patented system called “High PuritySystem”. With this method it is possible to achieve a quality standard as required by the major air conditioning and refrigerating system manufacturers. This technology allows you to obtain a gas humidity below the maximum limit (equal to 10 ppm). 
Therefore this type of cylinder (containing 800 gr. – 2 Kg) is the most suitable one to meet the needs of thermohydraulic market.


KryoSmart® Cylinders are used every time a small quantity of refrigerant is needed. They are mostly used in thermohydraulic market.


  • KryoSmart® Cylinders are manufactured in low-carbon steel and have a maximum working pressure equal to 48 bar.
  • A “Low Cost” and “Eco-Friendly” Solution.
  • Patented filling system “High Purity System”.
  • They reduce market prices.
