I do not think that you can prevent it. CaCl2 is a very aggressive medium, especially at positive tem-res. It will last for short time. Does it need to be CaCl2? I

Thanks. It is for liquid desiccant dehumidifier. CaCl2 is used for drying the air and need to cool it by refrigeration system.

At one plant we use iridium HE (NH3/CaCl2) and PE pipes for CaCl2 circuit .... ice cream factory ...
