The equipment automatically adjusts the temperature and cooling capacity of the refrigeration system according to the different water inputs and temperatures to reach the DI temperature required by the target.
The use of variable frequency control allows the output to be well regulated even when the water flow rate is unstable, thus achieving a high degree of temperature control accuracy.
2℃~20℃
Deionized Water Chiller
Suitable for situations where DI water is required from 2°C to 5°C in the manufacturing process. Normal temperature DI water into the temperature control unit, and then demand target temperature DI Water is Present, solve the problem of freezing easily when the water temperature is controlled within 5°C.
Our chillers are specially designed for deionized water process cooling

Water is passed through two charged porous electrodes: one positive and one negative. The positive electrode attracts and removes negatively charged ions, replacing them with hydroxide ions (OH-). Meanwhile, the negative electrode attracts and removes positively charged ions, replacing them with hydrogen ions (H+). When hydroxide and hydrogen ions combine, they form pure water molecules. This process results in completely purified water.
What Is Deionized Water?
Deionized (DI) water is extremely purified water in which all total dissolved solids and ions (charged molecules) are removed. Before water is deionized, it is filtered (sometimes through a reverse osmosis machine) in order to remove organic matter and other contaminants. Next, the water is run through a process called ion exchange.
What Is Deionized Water Used For?
DI water has many industrial and manufacturing applications in process cooling since it doesn’t leave behind mineral deposits and is free of corrosive salts. Its high purity levels mean it is used in ultra-sterile industries, such as pharmaceuticals, to mix medicines and cleanse lab equipment. It also has a very low electrical conductivity, which is ideal for use around electrical equipment. DI water is used to flush impurities and waste material away from sensitive equipment like circuit boards, microelectrics, and Electrical Discharge Machinery (EDM).


Deionized water chillers are specialized cooling systems designed to circulate ultra-pure water for temperature control in sensitive industrial and manufacturing processes. These chillers use water stripped of impurities and ions, making them ideal for applications requiring precise temperature regulation and protection against corrosion or contamination.
For industrial machinery that generates a lot of heat and requires the sensitivity of deionized water, specialized chillers are essential. Deionized water chillers pump deionized water in and around the equipment, solving two problems at once.
