1. Ethylene glycol units use the certain concentration ethylene glycol aqueous solution as secondary refrigerant. It can provide -30 ~ 5 ℃ freezing secondary refrigerant to adapt different users and cooling capacity requirements.
2. Through intelligent microcomputer control technology, according to the load varies, the units automatically adjust the devoted compressor output, it maintains the best match in the highest efficient at any time.
3. The units are installed with well-known brands new generation high-efficiency & high IPLV double screw compressors, 5:6 high-efficiency patent asymmetric teeth. Compressors are equipped with capacity controller to achieve muti-step or step-less energy adjustment.
4. Microcomputer control system, with strong security, communication, fault diagnosis and automatic adaptation function.
5. The main parts of refrigeration system are from famous brands at home and abroad, superior performance and reliable operation.
6. Set the high and low pressure protection, chilled water anti-freeze protection， power phase sequence protection, default phase protection, lack of water flow protection， compressor motor overload/overheating protection and auto-restart function on power failure, set password on control interface to prevent faulty operation.
