In stock: QTY : Item Pictures. Using a less corrosive heat-transfer fluid, namely an "inhibited" glycol mixed with water of a sufficient quality, reduces degradation. Inhalation: At room temperature, exposure to vapor is minimal due to low volatility. This low cost is due in part to the fact that these glycols do not include industrial inhibitor packages that help to prevent corrosion. $159.99 $ 159. The below table illustrates the comparative corrosion effects that inhibited and uninhibited glycols and plain water may have on metals commonly found in HVAC applications. Thought I'd come back and post an update for anyone searching for this information: I spoke with the PG supplier and the difference is simply that the inhibited PG has a food-grade inhibitor added to it which prevents metal corrosion. Dow® heat transfer fluid provides corrosion protection without reducing heat transfer efficiency caused by fouling. Not only do uninhibited glycols leave your system vulnerable to corrosion, they can also accelerate the problem.
