Because of the interest, some unscrupulous merchants in the market use customers’ insufficient knowledge of the specific product and market of refrigerant / refrigerant to make a large number of fakes and sales. In order to prevent customers from purchasing counterfeit and inferior refrigerants (refrigerants) without their knowledge, and causing major damage to customers’ units and work, recognizing the following points may help you distinguish between genuine and fake refrigerants:
1. DuPont DuPont, Honeywell (formerly Allied Signal), Ineos INEOS (formerly ICI), Arkema (formerly ATOFINA), Solvay (including Ausimont, Italy) And other major foreign refrigerant (refrigerant) manufacturers have stopped producing chlorofluorocarbon (CFC) refrigerant products (such as: R11, R12, R13, R502, R503) many years ago.
However, there are still a large number of illegal merchants in the market, claiming to be able to provide imported R11 (F11, monofluorotrichloromethane), R12 (difluorodichloromethane), R13 (trifluoromonochloromethane), R502, R503, etc. (Refrigerant) products. In fact, these illegal merchants basically provide fake products to users, and even the inside contains not the refrigerant (refrigerant) required by the user. For example, the so-called Lianxin R11 refrigerant (formerly the United States Letter company, the current Honeywell company has stopped producing R11 refrigerant many years ago; at the same time R11 is also a restricted import and export product).
2. R11, R12, R13, R502, R503 and other substances containing chlorofluorocarbons (CFCs) are products that have been restricted by the state (and also restricted from exporting). They claim to be able to provide imported R11 (F11, monofluorochloroform). ), R12 (difluoromethylene chloride), R13 (trifluoromonochloromethane), R502, R503 and other CFC-containing refrigerant (refrigerant) products, in fact, are all acts of deceptive customers (users) by illegal merchants. Users can inquire with the national environmental protection department if they can import R11, R12, R13, R502, R503 and other refrigerants (refrigerants) containing chlorofluorocarbons (CFCs).
3. According to the “National Perchlorofluorocarbon Product (CFCs) Production Quota Table for 2006” issued by the State Environmental Protection Administration, R11 (F11, monofluorotrichloromethane), R12 (difluorodichloromethane), R13 (trifluoro-1 Chloromethane), R502, R503 and other substances containing chlorofluorocarbons (CFCs) are all products produced under national quotas. For example, in 2006 there were only two factories that had production quotas for monofluorotrichloromethane (F11) and could provide refrigerant-grade R11 (F11, monofluorotrichloromethane) products.
