TRUEGARD 960 NSF Certified Food-Grade Propylene Glycol Inhibited Coolant 100% Concentrate - 330 TOTE

Yes, TRUEGARD 960 is a full-strength concentrate and must be diluted with water before use. The correct dilution ratio depends on the freeze protection level and operating temperature required for your specific application; consult the product data sheet for recommended mixing guidelines.

NSF certification independently verifies that TRUEGARD 960 is approved for use in systems where incidental contact with food or beverages may occur, such as in wineries, micro-breweries, and meatpacking plants. This certification helps facilities satisfy regulatory and safety requirements for heat transfer fluids used in food-adjacent environments.

Food-grade propylene glycol like TRUEGARD 960 uses a base fluid and inhibitor package that are cleared for incidental food contact, whereas standard industrial glycols may contain inhibitors not approved for food environments. Food-grade fluid is required whenever the heat transfer loop could come into contact - even accidentally - with food, beverages, or potable water.

TRUEGARD 960's inhibitor system is specifically formulated to prevent rust and corrosion in systems containing aluminum, brass, cast iron, copper, solder, and steel, making it compatible with the wide range of metals found in typical HVAC, refrigeration, and food-process equipment.

This wide temperature range means TRUEGARD 960 can serve in both low-temperature applications - such as immersion freezing, refrigeration coil defrosting, and cold room dehumidifying - and high-temperature applications like process heating and waste heat recovery, all within a single product.

TRUEGARD 960 is formulated as an affordable alternative to DOWFROST inhibited glycol coolant and is designed for the same antifreeze and heat transfer applications. When switching glycol products in an existing system, it is generally good practice to flush the system thoroughly before introducing the new fluid to avoid inhibitor incompatibility.
