The main difference between acid and alkali resistant chillers and ordinary standard chillers

In the chemical industry, bright chemicals are often adsorbed on the surface of the chiller components during the chemical production process, which is extremely corrosive. Therefore, the acid and alkali resistant industrial chiller is a refrigeration element specially tailored for customers. The device has anti-corrosion unit. It is also a special refrigerator for the oxidation treatment industry and the electroplating industry. In the electroplating industry, the ice water machine helps stabilize the metal and the metal ions, so that the metal quickly attaches to the electroplated parts, which not only increases the density and smoothness , And reduce the number of electroplating, improve production efficiency.

　　So, what is the difference between the acid and alkali resistant chiller and the commonly used standard chiller? We take water-cooled chillers used in the electroplating industry as an example.

　　1. Main configuration: both acid and alkali resistant chiller and standard chiller are composed of compressor, evaporator, condenser, electric control system and refrigeration accessories. During installation and use, additional cooling towers and circulating water pumps are required. The difference between the two is: the acid and alkali resistant chiller uses a titanium alloy plate exchange evaporator, an acid and alkali resistant water pump or a stainless steel water pump, while the standard chiller uses a shell and tube evaporator and an ordinary water pump, and an additional one is needed. Double-layer stainless steel ice bucket.

　　2. Cooling method: In the electroplating industry, acid and alkali-resistant chillers work in direct cooling mode. This cooling method can save installation materials and electricity for users, reduce machine wear, and is affordable. The standard chiller works by indirect cooling. In order to prevent the chiller from being corroded by the electroplating solution, in addition to adding a cooling tower and a water pump, a titanium alloy plate-exchange evaporator and a double-layer stainless steel ice water bucket are also required to form the cooling system. Circulatory system.
