Hey everybody I’m John McCoy, the Production Manager at G&D Chillers. We’re going to get into what glycol is. It’s basically an antifreeze. There are two main types of glycol: there’s ethylene glycol, that’s what your car will use as an antifreeze, and then there’s propylene glycol. That’s what we use. It’s non-toxic. We’ve got to use the inhibited propylene glycol. It’s got inhibitors inside there to make sure that we don’t get any microfilm build up, rust, things like that, inside the piping system that you have installed in your facility. Contact Us
