TRUEGARD-Ethylene Glycol Inhibited-Heat Transfer Fluid 100% Concentrate - 55 Gallon Drum

Yes, this is a 100% concentrate that must be mixed with water prior to use. When properly diluted, solutions provide freeze protection to below -60°F and burst protection to -100°F, so the dilution ratio should be chosen based on the minimum temperature protection required for your application.

Freeze protection (-60°F) refers to the temperature at which the fluid itself begins to solidify and flow stops, while burst protection (-100°F) means the solution will not expand enough to rupture pipes or system components even at that more extreme temperature - providing a critical safety margin below the freeze point.

This fluid is suitable for closed loop systems, water-based haul, process heating and cooling, and food industry applications, provided the system operates within the stated temperature range of -60°F to 250°F.

The fluorescent pink dye is added specifically to aid in leak detection - if a leak develops anywhere in the system, the distinctive color makes it much easier to identify the source quickly.

Yes, the formulation includes a specially designed package of industrial corrosion inhibitors, making it appropriate for use in closed-loop industrial systems where protection of metal components is a concern.

Ethylene glycol-based fluids like this one generally offer broader temperature performance and are a common choice for industrial process heating and cooling systems. Propylene glycol formulas are typically selected when a lower-toxicity or more environmentally acceptable chemistry is required. Truegard offers both formulations, so reviewing the application requirements and any relevant safety considerations can guide the right choice.
