Replace the calcium chloride aqueous solution with an ethylene glycol aqueous solution?
Thread Content
Currently, ethylene glycol is used as a coolant, and due to its excellent physicochemical properties, particularly its low corrosivity and low toxicity, it is increasingly replacing calcium chloride aqueous solutions. Are there any industries that can only use calcium chloride and not ethylene glycol? Submitted for discussion! Feel free to leave a message!
Ice cream production line; the project still uses calcium chloride brine at -35°C
In my opinion, calcium chloride should be used unless the consumption is high and there are severe leaks. In the case of a closed system where the consumption is low, inhibitory ethylene glycol is the best choice; it is an ethylene glycol specifically designed for use in refrigeration systems. It is not corrosive.
