TRUEGARD -Ethylene Glycol Uninhibited-Heat Transfer Fluid 50/50 - 55 Gallon Drum

Uninhibited means the fluid contains no corrosion inhibitors or chemical additives. It delivers freeze and burst protection but does not protect metal system components from corrosion on its own, so users who require corrosion protection should add compatible inhibitors separately or consider an inhibited formulation instead.

This fluid is pre-mixed at a 50/50 ratio of ethylene glycol to water, so it is ready to use directly without any further dilution. Diluting it further with water would reduce the freeze and burst protection levels stated on the product.

Freeze protection (-60°F) is the temperature at which the fluid starts to solidify, while burst protection (-100°F) is the lower threshold at which the fluid's controlled expansion prevents pipes or containers from rupturing even if the fluid freezes solid. In extremely cold environments, burst protection is the more critical spec for preventing physical system damage.

The fluorescent pink dye serves a functional purpose: it makes it easier to visually detect leaks anywhere in the system. Because the color is distinct and bright, even small seeps become apparent on equipment surfaces or surrounding areas.

According to the product data, it is suitable for closed-loop systems, water-based haul, process heating and cooling, and food industry applications, all within its operational temperature range of -60°F to 250°F. Users should confirm their specific system materials and requirements are compatible with an uninhibited ethylene glycol fluid before use.

The product data states it is suitable for food industry applications within its rated temperature range (-60°F to 250°F), but no specific third-party certification such as NSF registration is mentioned in the available product information. Buyers with strict regulatory compliance requirements should verify applicable certifications directly with Truegard before use.
