Cooling condition: Chilled water inlet/outlet temperature 0/-5 ℃, ambient dry bulb temperature 35℃
Temperature term: Chilled water outlet temperature -7℃~-5℃;
Chilled water side should be added by 25% glycol water or 20% calcium chloride as anti-freeze.

Application: It is mainly used to cool down the chemical reaction kettle (chemical heat exchanger), and take away the huge heat produced by chemical reaction in time so as to achieve the purpose of cooling (cooling), so as to improve the product quality and production efficiency.
