METALGUARD® H60

METALGUARD H60 is an NSF registered food grade heat transfer fluid additive package that is mixed with a USP grade propylene glycol base. It is used where it may come into incidental or accidental contact with food, beverage products or drinking water may occur. It may also be used in HVAC systems, fire systems, solar heating, refrigeration warehouse floor heating, sidewalk/playing field subsurface heating/cooling, cold room dehumidification systems, cosmetic or pharmaceutical processing, and it also makes an excellent additive package to make RV/marine winterizing antifreeze.

METALGUARD H60 contains food grade dipotassium phosphate as its primary inhibitor. All ingredients are classified as GRAS, or generally recognized as safe, by the FDA and acceptable as food additives (Food Additives Regulations, Subparts 182 and 184). The regulation for dipotassium phosphate is CFR 182.6285. It also meets Food Chemicals Codex. The METALGUARD H60 inhibitor package contains ingredients that help prevent corrosion of metals and buffers the pH to maintain it in the optimal range.

The recommended operating temperature range of METALGUARD H60 is -45ºF (-50°C) to +250ºF (120°C). The lowest temperature to which the finished product can be exposed depends upon the balance of glycol and water. METALGUARD H60 can be used to provide both freezing protection and burst protection for systems which may be exposed to very low temperatures.
