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.
Product Features
Product Parameters
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.
