LTG series Industrial Screw Chiller

LTG series Industrial Screw Chiller

APPLICATIONS

Applicable to various chemical, pharmaceutical, mechanical and other fields as process cooling sources, can provide -110℃~30℃ refrigeration medium, can be used as ice storage, low temperature air supply and other process cooling sources required by production processes.

 

According to the heat load required by the specific production, the outlet water temperature of the refrigerant is used as the control point, and the control center sends instructions to adjust the movement of the energy regulation slide valve to adjust the load of the compressor unit, so as to achieve the real energy-saving effect.

Product Features

This series of screw chillers has a total of 6 temperature sections to choose from, all of which are water-cooled.

APPLICATIONS

Temperature control unit of semiconductor FAB process

Semiconductor manufacturing is a process with extremely high environmental requirements, and many process steps are very sensitive to temperature.
Precise temperature control can ensure uniform thickness and accurate composition of deposited films, thereby improving chip performance and yield.

for Semiconductor packaging & testing process

Semiconductor packaging and testing process is a key link in the semiconductor production process, including wafer testing, chip packaging and post-packaging testing. This process requires not only a high degree of accuracy and reliability, but also strict temperature control to ensure product quality and performance.
