Kryon® 404A The reference product for commercial refrigeration

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® 404A is a non-ozone depleting refrigerant gas developed for long-term replacement of R-22 (HCFC) in low and medium temperature commercial refrigeration.
Kryon® 404A is a slightly zeotropic mixture. For this reason it is necessary to charge systems only with refrigerant in the liquid phase, and not with vapour because that would cause a change in the composition of refrigerant that could damage the system.
Kryon® 404A is used in low and medium commercial and industrial refrigeration, as for example supermarket display cabinets, cold rooms, stands, refrigerated transport and ice making machines. 
  • Capacity and efficiency similar to R-502.
  • Its use has been approved by the major compressor manufacturers
Recommended Lubricants
Kryon® 404A is used with all lubricants that are miscible with HFC refrigerants. General Gas recommend the use of a lubricant like polyol ester ( POE ) that has been approved by compressor manufacturers. Different kinds of polyol ester (POE) are not interchangeable. In case of conversion of the system, please consult the compressor manufacturer in order to verify the correct type and viscosity grade.

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.
