## The hazards of low-concentration refrigerants

The refrigerant in industrial cryogenic refrigerators is the blood of compressor. The purity of refrigerant is particularly important for industrial cryogenic refrigerators. The high purity refrigerant has obvious refrigeration effect, fast temperature drop and large cooling capacity. Low purity refrigerants not only fail to achieve the desired temperature, but also damage the compressor. When debugging… Read more The hazards of low-concentration refrigerants
