Be careful. If you are changing and existing system. CaCl2 and Glycols do not mix. The stsrem must be 100% flushed of Calcium chloride before adding glycol.

Are the two interchangable as far as pump, and line sizing?

Hi everybody and many thanks
we like to use Monopropylene Glycol instead of Calcium chloride for the same machine so the same pump and the same lines but maybe we will face problem with viscosity. i do not know what shall i do? any advice?
