Having worked for
Rosco in designing
fog machines many years ago what I can add has to do with the formula. If you are working with a machine that uses a heat exchanger, then the fluid composition is matched to the temperature of said heat exchanger. If you run a fluid in a machine and it comes out as a wet
fog then while you will not damage your machine you will also only get a mess. If you smell a burnt odor when using a fluid then stop immediately and flush the machine with distilled water. You are burning the fluid and that can lead to
build up which will clog the machine. You may find a different fluid works fine and the temperatures match.
Fog fluid is made up of a chemical family called Glycol's, there are a number of variations, some of which are toxic, like the one's used in anti-freeze. Years ago an unscrupulous dealer was selling anti-freeze, and got caught.
You will never go wrong with keeping the fluid and machine the same, but only testing will tell.
