(1) Adopting two-stage comoression technology, without pre-cooling, the evaporature temperature can be directly reduced from cold storage temperature to -65ºC.
(2) The motor is arranged between the low-pressure and the high-pressure stage, to prevent condensation or frost in the motor shell and the terminal box to ensure electrical safety. At the same time, the internal flow path is optimized to reduce pressure loss.
(3) Both the suction side and the replenishing side are large-area filters, which protect the compressor while reducing the pressure loss.
(4) Equipped with a built-in protection module that monitors and detects conditions such as phase reversal, phase loss, overvoltage, undervoltage, motor overheating, and excessive discharge temperature.
Leveraging our precision manufacturing base at headquarters, we have successively introduced internationally leading equipment such as the UK Holroyd profile grinders, Germany's KAPP profile grinders, and Germany's LEITZ coordinate measuring machines. This ensures that our products deliver exceptional performance across various commercial and industrial environments.
The company's products are widely used in the food, fishery, pharmaceutical, chemical, scientific research, and logistics sectors. In response to the needs of deep-sea fishing vessels, northern heating, industrial high-temperature heat pumps, quick-freezing warehouses, quick-freezing machines, and freeze-drying equipment, the company has developed a range of specialized screw compressors that precisely cater to each of these specific fields.
