Kryon® 404A The reference product for commercial refrigeration
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.
Applications
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.
Performance
- 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.
Kryon® Refrigerant Solutions 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.
DOT39 cylinders and cartons
Kryon® non-refillable cylinders are manufactured according to DOT 39 specifications.
Each cylinder is packed in high-resistance/high quality cardboard box, in order to make its transport safer and the storage easier.
Non-Refillable Cylinders are filled by Kryon® Refrigerant Solutions by using a patented technology called “High Purity System”. Thanks to this technology it is possible to achieve the highest quality standard, as required by the major air conditioning and refrigerating system manufacturers, by keeping the gas humidity far below the maximum limit allowed by AHRI 700 standards (equal to 10 ppm).
