Note:
1. Refrigeration condition: The refrigerant is a 60% ethylene glycol aqueous solution; The inlet/outlet temperature of the cooling water is 32/37 ℃.
2. Scope of work: The outlet temperature of the cooling water is between 22 ℃ and 37 ℃, and the inlet temperature difference of the cooling water is between 3.5 ℃ and 10 ℃; The outlet temperature of the frozen liquid is -5 ℃ to -30 ℃, and the temperature difference between the inlet and outlet of the frozen liquid is 2.5 ℃ to 5 ℃.
3、This series of units can all be equipped with a heat recovery system (hot water temperature 35 ℃~60 ℃)
4、At the same time, our company can customize various anti-corrosion and explosion-proof units according to the specific needs of customers.
5、If there are any changes to the above specifications without prior notice, this will help our company to bring the latest technological achievements to customers at any time.
