How to choose the cold water machine for electroplating industry?
    For electroplating, electrophoresis coating, electroplating production line, anodic oxidation and so on are aimed at plating bath inside the plating solution to cool. How to choose the cold water machine. There are two types of cooling, direct cooling and indirect cooling.
    Water cooled chillers direct cooling in the electroplating industry (oxidation) refrigeration principle: cooling tower bottom basin of the water pump transported to the condenser of industrial chiller condenser for cooling, and then flows back into the cooling tower and spray cooling tower through the fan on the cooling water flowing back into the cooling tower bottom basin, so repeat the operation. At the same time the condenser cooling refrigerant inside the evaporator in liquefaction, and then flows into the cold bore for evaporation, evaporation and absorption of heat, the cold bore in sulfuric acid (bath) for cooling, cooling after the sulfuric acid delivery to the plating through the pump (oxidation) tank, such a cycle.
    Indirect cooling of water cooled chiller in the electroplating (oxidation) industry: the water in the bottom of the cooling tower is fed to the condenser of the water cooler through the water pump to cool the condenser. Back to the cooling tower spray down and through the cooling tower on the fan cooling water, and then return to the bottom of the cooling tower, so that the cycle of operation. At the same time inside the condenser cooling refrigerant liquefied, then flows into the evaporator water tank for evaporation, and evaporation to absorb heat, so the water in the water tank for cooling, cooling water is conveyed to the heat exchanger by the pump (separated, side side of the water, sulfuric acid, and then through the process of heat transfer on the sulfuric acid cooling, such a cycle. The advantage of this product is that it is easy to install, the service life is longer than the direct freezing, acid and alkali is not easy to corrode the cold water machine. The general purpose of the heat exchanger for the plate for the airtight
