Cold water machine direct cooling tower bottom basin of the water pump transported to the condenser cooling water machine of condenser for cooling, and then back into the cooling tower and spray by fan chemical chiller cooling tower for cooling back into the cooling tower bottom basin of water, so the cycle of operation. At the same time inside the condenser cooling liquefied refrigerant then, the flow into the evaporator for evaporation, and evaporation to absorb heat, thus the evaporator in sulfuric acid (bath) for cooling, cooling after the sulfuric acid delivery to the plating through the pump (oxidation) tank, such a cycle.
        Refrigeration principle of indirect freezing in the electroplating (oxidation) industry: the water in the bottom of the cooling tower is pumped to the condenser of the water cooler through the water pump to cool the condenser. And then back into the cooling tower and the spray cooling tower fan on the water cooling, and then back into the cooling tower bottom basin, so 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, which is on the water in the water cooling, cooling water is conveyed to the heat exchanger by the pump (separated, side of the water, while sulfuric acid), then through the heat transfer of cooling of sulfuric acid, then a cyclic process. 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 chiller
