LTZ Series- with Heating Function

LTZ Series- with Heating Function

APPLICATIONS

LTZ variable frequency belt heating function series, temperature control range: -40℃~+90℃, temperature control accuracy: ±0.3℃. The variable frequency unit adopts advanced variable frequency technology to accurately control the compression and fan operating speed, and quickly cools through intelligent adjustment of the electronic expansion valve.

High efficiency and energy saving: The variable frequency compressor unit changes the operating speed of the DC compressor at any time according to the user's cold and hot load requirements through the built-in variable frequency device, thereby avoiding the compressor and the full load of the electric heating to compete, maintain the stable working state of the unit, and achieve energy saving.

Rapid cooling: The variable frequency unit adopts advanced variable frequency technology to accurately control the compression and fan operating speed, and quickly cools through intelligent adjustment of the electronic expansion valve.

Ultra-low noise: The variable frequency unit adopts a variable frequency scroll or twin-rotor compressor, which greatly reduces the gyroscopic imbalance, making the vibration of the unit very small, about 1/2 of that of a conventional compressor, combined with multiple noise reduction measures, extremely quiet.

High environmental adaptability: The variable frequency unit adopts low frequency starting, small starting current, and small impact on the power grid. It has strong adaptability to voltage and can be started under a wide voltage range.

Long life: The variable frequency unit will not start and stop frequently, effectively reducing the loss of the unit when starting and stopping, and extending the life of the unit.

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.
