The new Circulation Chiller has no secondary heat exchange. Compared with traditional liquid cooling equipment, it reduces the heat transfer loss caused by secondary heat exchange and improves energy efficiency by more than 30%. The new direct cooler can provide a pure liquid heat exchange medium. Compared with the traditional Circulation Chiller gas-liquid two-phase mixed heat exchange medium, the new Circulation Chiller makes full use of the latent heat of the refrigerant, greatly improves the heat exchange density, and reduces the required heat exchange area, which can meet the high power density requirements of semiconductor and other industries.

ZLTZ series circulation chiller has the ability to supply liquid in multiple ways, and can accurately control the cooling capacity of each branch to meet the temperature control requirements of each branch. The new direct cooling machine adopts PT100 high-precision temperature sensor and PID intelligent control system, with extremely small temperature error range and accurate and reliable temperature control.

Feature 1

One ZLTZ circulation chiller with multiple ESC Chucks to control different temperatures

Feature 2

Applicable to high heat absorption and high uniformity temperature control applications. Under the same flow conditions, the heat transfer efficiency of heat transfer and temperature control is more than 5 times that of heat transfer oil.

Feature 3

When the Chuck is set to 200℃ constant temperature, the refrigeration system supplies cold air and the equipment can operate normally for a long time. When the cold plate is replaced, the refrigerant can be automatically recovered.
