LTZ Variable Frequency Series Refrigeration Circulators Chillers

LTZ Variable Frequency Series Refrigeration Circulators 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.

Applications

Semiconductor FAB process temperature control solution

Semiconductor packaging & testing process temperature control solution

The 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 not only requires a high degree of precision and reliability, but also requires strict control of temperature to ensure product quality and performance.

Microchannel | Tubular Reactor Temperature Control Solution

Aerospace materials | Test equipment temperature control solution

Temperature control solution for hydrogen energy industry

Temperature control solution for New material | Special gas production

New materials, as newly developed or developing structural materials with excellent performance and functional materials with special properties, have extremely high requirements for temperature control in their research and development and production processes. The production of special gases, such as oxygen, nitrogen, argon and other industrial gases, also requires precise temperature control to ensure product quality and production efficiency.

Temperature control solution for Distillation and concentration

The basic principle of distillation and concentration is to utilize the difference in volatility of the components in the mixture, vaporize the volatile components under heating conditions, and then collect them through condensation to achieve the purpose of separation and concentration. In this complex and delicate process, temperature control technology is not only the key to ensure smooth operation, but also an important factor affecting product quality and efficiency.
