As a universally used high-temperature refrigerant, R42b is mainly used in refrigeration and air-conditioning systems in high-temperature environment, heat pumps, and as an important components for multi-variety mixed refrigerants, as well as in polymer (plastic) foaming, constant temperature control switches and the midbody for aviation propellants. It can also used as a chemical raw material.
Storage and transportation (safety classification A2) :
The steel cylinder, as a pressure vessel, should be stored in a cool, ventilated warehouse. Avoid direct sunlight exposure, keep away from fire and heat sources, and make sure to store it separately from combustibles and oxidants. The storage area should be equipped with leakage emergency treatment equipment.
The safety cap must be screwed tight on the cylinder in transportation. The cylinder should be placed flat in general, with mouth to the same direction, instead of crisscrossing; its height should not exceed that of the fence of the vehicle and it should be secured with wooden wedges to prevent from rolling. It should be handled lights during loading and unloading to prevent from crushing and collision, and avoid damage to the cylinder and accessories such as valve, etc.
Lubricant recommendations :
Mineral oil (MO) or alkylbenzene (AB) synthetic oil
Tips: Selection of refrigerating oil for different types of equipment and different scenarios shall follow the recommendations of the refrigeration compressor and refrigeration (conditioning) equipment manufacturers, or be determined based on the equivalent design and technician requirement according to the specific conditions of the refrigeration compressor and refrigeration equipment, that is, using only the refrigerating oil that matches the equipment or its application purpose.
