Freeze protection and corrosion control across a research campus cooling system

The Chinese Institute Brain Research Center was established in Beijing on 22 March 2018 by the Beijing municipal government together with the Chinese Academy of Sciences, Peking University, Tsinghua University, Beijing Normal University, the Chinese Academy of Medical Sciences and the Chinese Academy of Traditional Chinese Medicine. Its stated programme covers technology platforms and resource libraries, major disease-related cognitive impairment, brain-like computing and brain-computer intelligence, intellectual development, and the cognitive development of the adolescent brain.

The manufacturer's application page states that Glacier Coolant helps the centre solve freezing during system downtime in winter, keeps the equipment free of corrosion, and increases the system's operating time. A later article in the manufacturer's news archive describes the same installation as one where Glacier Coolant products address two specific problems: preventing system freezing during winter shutdowns, and extending operating time through improved thermal management.

Neither publication dates the cooling installation or names a model; the 2018 date belongs to the centre's establishment, not to the fluid supply. The duty described — a loop that sits idle through a Beijing winter and has to start again without damage, across mixed metals — is the application the catalogue addresses with the LM-4 family of water-dilutable inhibited secondary coolants, which is why that family is referenced here. Confirm the model, concentration and material compatibility for the actual loop.
