Refrigerant R507
Refrigerant R507
As the long-term substitute for R502, R507 used mainly in the low temperature refrigeranting systems.
Refrigerant R406a
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.
Refrigerant R408a
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
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.
Refrigerant R404a
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 R407c
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.
4-valve digital manifold
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 R410A
Refrigerant R410A
R410A refrigerant is used in new residential and commercial air conditioning systems, heat pumps, dehumidifiers and small chillers. R-410A is also being considered in some medium temperature refrigeration applications.

Refrigerant R22 refrigerant in the market with "fake" spurious

In a refrigeration engineering, due to the poor heat transfer effect, experts have spent a great deal of time and effort, the cold storage, cold storage engineering design installation, adjustment made a comprehensive analysis of each link, eliminate heat exchanger structure and performance, doubt perfusion R22 refrigerant has a problem.Back to normal manufacturer buy bottled R22 again after filling effect is improved obviously.Expert judgment, therefore, the market appeared "fake" R22 refrigerant.   

Due to individual manufacturer backward production technology, product quality control is lax, causing unqualified purity of R22 into the market, the existence of non azeotropic by-products, will make the whole process of phase change of the refrigerant cycle was badly damaged by heat transfer capacity and air plug, condensing temperature on the high side and change the condition of heat collapse.What is more alarming, some impurities in the refrigerant is flammable, it brings certain security hidden danger to the user.  

By the specialized agencies, sampling inspection, in which three cans of "fake" R22 bottle inside respectively detected a fluoride, chloride methane (CClFH2) and methyl chloride (CClH3), one of the methyl chloride in two cans of sampling gas content as high as 84% and 84 respectively.Refrigeration express reporter found in consulting, a fluoride, chloride methane and methyl chloride are R22 the by-product in the process of production, with incomplete substitution reaction by-products of R22, due to the partial pressure, under a certain total pressure the gas liquid two phase of the actual temperature and the pressure corresponding to the saturation temperature appear large deviation, lead to actual heat exchange effect is deviating from the design point, thus severely reduce the heat transfer performance, the entire project stalled and repeatedly, waste a great deal of energy and financial resources.
