R134a Packed in the cylinder, specifications have 200 g, 250 g, 300 g, 13.6 kg, 100 kg, 400 kg, 800 kg, filling ratio is not greater than 1.1 kg/L, R134a must be stored in a cool, dry and ventilated place, avoid insolation, drench. Everything as alternative refrigerant R12, many of its features is similar with R12 R134a has a very low toxicity, no flammable in air, security category for A1, refrigerant is very safe. Everything has a good chemical stability, however, because of its water soluble than R22, so adverse to the refrigeration system, even if there is a small amount of water, under the action of lubricating oil and so on, will produce a acid, carbon monoxide, carbon dioxide or to metal corrosion effect, or "copper" effect, so everything on the system of the dry and clean even more demanding. Everything for steel, iron, copper, aluminum and other metal mutual chemical reaction phenomenon has not been found, only have a minor effect on zinc.
