High and low temperature refrigeration unit.

The high and low temperature refrigeration unit achieves temperature control through a compression cycle system, utilizing the phase change of the refrigerant to absorb or release heat. In the laboratory, it is used to simulate the performance changes of materials under different temperature environments, commonly applied in scenarios such as coating weather resistance testing and plastic low-temperature brittleness testing.
Selection
When selecting, it is necessary to match the experimental temperature range and accuracy requirements, determine the working chamber volume based on sample size, pay attention to the cooling rate indicator, check the compressor type and refrigerant environmental friendliness, confirm the equipment protection level and power configuration, and evaluate maintenance convenience and brand technical service capabilities.
