Refrigerant R134a: HFC-134a is used as refrigerant in automobile air-conditioning, household and commercial refrigerant applications. It can also be used as aerosol, flame retardan, and blowing agent in pharmaceutical, agro-chemical, cosmetics and cleaning sectors.

Refrigerant R407c: R407C is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of R-32, R-125, and R-134a (20/40/40). Applications include residential and commercial air conditioning systems, non-flooded evaporator chillers, and some commercial refrigeration systems. Since R-407C has similar properties to R-22, it is possible (with modifications) to use it in the same equipment designed for R-22 today.

Refrigerant R404a: R404A is formulated to closely match the properties of Refrigerant R502, making it useful for a variety of medium and low temperature refrigeration applications.Refrigerant R404A has been approved by many refrigeration compressor and system manufacturers for use in new refrigeration equipment such as food display and storage cases, cold storage rooms, ice machines, transportation, and process refrigeration.

Refrigerant R406a: R-406A is a mixture of three components chlorodifluoromethane (R-22), isobutane (R-600a) and chlorodifluoroethane (R-142b) in the ratio 55/4/41. R406A was designed as a replacement for R-12, which is compatible with the typical mineral oil lubricants used in R-12 systems. It has a range of boiling points which may increase the effectiveness of the heat transfer elements in refrigeration equipment. As it contains R-22, its future is limited due to eventual phase-out.

4-valve digital manifold: 1.Pressure and vacuum gauge shift function. 2.Build-in 82 refrigerants according to U.S.A.NIST standarcl refrigerants pressure and temperature relationship database. 3.Real-time vacuum pressure test and percent indicate. 4.Low power indicate.Batteries life:30H.9V.

Refrigerant R507: As the long-term substitute for R502, R507 used mainly in the low temperature refrigeranting systems.

Refrigerant R408a: R-408A is a retrofit solution for medium and low temperature refrigeration systems that are currently using R-502. R-408A should not be mixed with R-502 or used to top off the charge of an existing system operating on R-502.

Refrigerant R22: Chlorodifluoromethane (HCFC-22), a colorless gas at room temperature, is a colorless, non - toxic, non-flammable and transparent liquid under the pressure created by itself. It has excellent thermal and chemical stabilities and no corrosivity to metals. Its main applications include refrigerant(-80℃grade), raw material for PTFE production and intermediate for Halon 1211 production.

Export HCFC:Enterprise principle for examination and approval of a not more than 300 tons

On February 25, national import and export management office said in a news release, the ozone-layer-depleting substances for as, in order to guarantee clearance rate, optimize the resources of examination and approval, a one-time approval number of production enterprises in principle does not exceed 300 tons;Trade type enterprise does not exceed 100 tons.

To prevent possible illegal, in the process of import and export trade violations and uncontrollable risk, in principle does not support the three of HCFCs import and export trade practices.
