Identify the authenticity of Danfoss compressors, solenoid valves, expansion valves, and filters Danfoss T2 valve true and false comparison:
(Authentic picture above)
(The imitation below)
Resolution: 1. After 2012, Danfoss T2 series valve products have raised design at the 1st position, but imitation products do not. Source of this article: Refrigeration Encyclopedia. 2. The 2nd position is laser welding of diaphragm. The genuine welding position is relatively flat, the edges and corners are more clear, the imitation is non-laser welding, and the welding part is rough. 3. The positions 3 and 4 are the same laser welding technology. The genuine welding section is smooth, the welding end is bright silver, the imitation is non-laser welding, and the welding end is dark gray. 4. The color of the genuine valve body is pure brass, and the color of the imitation valve body is yellow with red. The capillary of Danfoss T2 valve is made of stainless steel with brighter color. The color of the imitation in the picture below is dark gray.
"Danfoss" logo on top The maximum pipe diameter scale value is 1 1/8 (28mm) There is an "s" mark below the scale. Danfoss solenoid valve true and false comparison: 1. The authentic Danfoss coil has the "danfoss" logo (as shown below) (below):
2. The authentic Danfoss coil has a specific production date (below):
3. There are four small shallow pits at the bottom of the authentic Danfoss coil (below):
4. The screw of the authentic Danfoss coil connection terminal box has an anti-shedding design (below):
Danfoss filter true and false comparison: 1. At the bottom of the Danfoss filter label, there is a fluorescent label specially used to distinguish authenticity. The fluorescent label can see the "danfoss" logo at a certain angle. Using a magnifying glass, it can be seen that there are 10 anti-counterfeiting codes. The last two digits of the real Danfoss filter The code is generally different.
2. The color of Danfoss filter is black, using powder coating technology (strong anti-corrosion ability), and its appearance is smooth and translucent.
3. Danfoss filters are all sintered solid filter cores, which reduces the risk of friction between molecular sieves to produce powder. When you take out a real Danfoss filter and shake it in your ear, there will be no abnormal noise inside.
4. Danfoss filters are all produced in Mexico before 2012, and filters produced in India will not appear until 2012.
Danfoss compressor genuine logo: 1. The Danfoss logo (Danfoss) only uses a unique red color. The (Maneurop) logo is printed on the bottom of the piston compressor label. The nameplate is printed with visible pre-cut lines. If the nameplate is removed, the four corners of the nameplate will be missing.
2. There is a QR code in the lower right corner of the label. Scan with a third-party App (such as: I check) to obtain a set of numbers, which is consistent with the compressor model and serial number on the label.
3. There is a pre-cut on the four corners of the new label of the authentic Danfoss Me Youle compressor. If it is peeled off and reposted, the corners will be destroyed
