Selection of Industrial Chillers in Electroplating and Electrophoretic Oxidation Industries

 

Many friends do not know how to select the industrial chiller in the electroplating and electrophoretic oxidation industry, so this article will explain this aspect in detail. For electroplating, electrophoretic coating, electroplating production line, anodizing, etc., it is aimed at cooling the electroplating solution in the electroplating tank. How to choose a chiller? There are two cooling methods, direct cooling and indirect cooling. The cooling principle of water-cooled chiller direct cooling in electroplating and electrophoretic oxidation industries: the water in the bottom basin of the cooling tower is transported to the condenser of the chiller through the water pump to cool the condenser, and then When it flows back into the cooling tower and sprays down, the water is cooled by the fan on the top of the cooling tower and then flows back to the bottom basin of the cooling tower, and it runs in a cycle. The internal evaporator evaporates, and absorbs heat when evaporating, so as to cool the sulfuric acid (tank) in the cold gun, and the cooled sulfuric acid is transported to the electroplating and electrophoresis oxidation industry tank through the water pump, just such a cycle process .

Refrigeration principle of indirect cooling of water-cooled chiller in electroplating and electrophoresis oxidation industry: The water in the bottom basin of the cooling tower is transported to the condenser of the chiller through the water pump to cool the condenser. Then it flows back into the cooling tower and sprays down When the water is cooled down by the fan on the top of the cooling tower, it flows back to the bottom basin of the cooling tower, and so on. At the same time, it needs to absorb heat, so as to cool the water in the water tank. The cooled water is transported to the heat exchanger through the water pump (separated in the middle, with water on one side and sulfuric acid on the other), and then the sulfuric acid is carried out through the process of heat transfer. In order to cool down, it is just such a cycle process. The advantages of this product are that it is easy to install, has a relatively long service life compared to direct cooling, and acid and alkali are not easy to corrode the chiller. Generally, the heat exchanger of this type of chiller is a closed plate replacement.

In addition to such indirect cooling, another method is to use the coil in the electroplating tank, and then the chilled water provided by the industrial chiller circulates in the coil to cool the electroplating solution. In this way, the ordinary chiller can meet the requirements.
