1. Acid cooler is an automatic equipment which can quickly cool dilute sulfuric acid at room temperature of 25 ℃ to 5-8 ℃ through heat exchanger.

2. The whole process of plastic material, no other impurities, closed operation.

3. When dilutesulfuric acid is added to some chemical agents, chemical reactions will be produced, which will release heat, which will cause the temperature of chemical agents to rise and the molecular reaction will be unstable. For example, in the internalizationprocess in the lead-acid battery industry, when dilute sulfuric acid at room temperature is added to the battery, the active material of lead plate reacts with dilute sulfuric acid, and the temperature rises, which will cause the plastic shell of thebattery to expand and cause the product to be scrapped. When dilute sulfuric acid is cooled to 5-8 ℃ and then injected into the battery, the temperature will rise, but it can be controlled within the temperature range that the plastic box of the batterycan bear, so as to ensure that the yield of the battery is significantly improved.
