LTZ Variable Frequency Series Low Temperature Chillers

LTZ Variable Frequency Series Low Temperature Chillers

APPLICATIONS

LTZ series low-temperature freezers use frequency conversion technology to achieve high-efficiency energy saving of products, temperature control range: -100℃~30℃, temperature control accuracy: ±0.3℃

The variable frequency compressor unit changes the operating speed of the DC compressor at any time according to the user's cooling and heating load requirements through the built-in frequency conversion device, thereby avoiding the compressor and electric heating full load confrontation, maintaining a stable working state of the unit and achieving energy-saving effects.

Product Features

This series of low temperature chillers has 6 temperature ranges to choose from.

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.
