Características
R-428A is a near azeotropic, zero ozone depleting HFC and HC refrigerant gas mixture used as a direct (drop-in) substitute for R-502 and its HCFC substitutes such as R-408A, DI-44, HP80, in a wide variety of medium and low temperature refrigeration applications.
– No harm to the ozone layer, ODP = 0.
– It requires the replacement of mineral or alkylbenzene oil with POE synthetic oil.
– They allow the maintenance of existing equipment.
– In case of leakage, empty and carry out a new full charge.
– Lower discharge temperatures than R-22, which extends the life of the compressor.
– It achieves similar cooling capacity and energy efficiency to R-22 in most systems.
– Global Warming Potential (GWP): 1774
– Boiling point at 1.013 bar (ºC): -43.5
– Temperature glide or glide (ºC): 7,4
– Saturated vapor density at 25ºC (kg/m3): 43.33
– UN NO.: 3340
– Safety classification: A1. Low toxicity and non-flammable.
– Always load in liquid phase.
When R-22 was banned in new equipment, equipment manufacturers took advantage in many cases of the same production lines of R-22 air conditioning equipment to continue manufacturing them for R-407C but this time with synthetic POE oil instead of mineral oil. Not recommended for flooded evaporators or centrifugal compressors.
