R402A is a replacement for existing medium-and low-temperature commercial refrigeration systems such as freezers, portable refrigerators, and supermarket refrigeration systemsR502theHCFC refrigerant, has the advantage of low exhaust pressure. In most integral and closed-coupled systems, there is no need to change lubricating oil, and AB lubricating oil is recommended for the best oil return effect.
