Arctic Assist 50/50

Why Arctic Assist 50/50

Industrial buyers select Arctic Assist 50/50 when operations demand a 50 percent USP-grade propylene glycol concentration for dependable freeze and burst protection in closed-loop systems. Supplying a pre-mixed liquid eliminates the variables introduced by on-site water blending, ensuring a locked point on the freeze protection curve that remains consistent across closed-loop systems. Because it arrives as a pre-diluted, low-viscosity fluid, facilities avoid the calculation errors that can compromise thermal efficiency or damage sensitive equipment during extreme temperature swings. The highly visible pink dyed liquid provides an immediate visual confirmation of fluid levels, system integrity, and active flow within complex piping networks. Formulated from USP-grade propylene glycol (CAS 57-55-6, formula C3H8O2), this fluid provides consistent, reliable quality for industrial and facility freeze-protection use. Propylene glycol is low in toxicity — the reason it is specified over ethylene glycol wherever incidental human or environmental contact is a concern.

System engineers must evaluate fluid chemistry to determine the exact need for inhibited or uninhibited closed-loop protection. While inhibited fluids contain added corrosion deterrents for long-term multi-metal protection, this specific uninhibited formulation provides a pure baseline fluid free of heavy additives, making it highly applicable for industrial systems where additive interference must be avoided.

Best Applications for This Grade

• Commonly applied in specialized industrial heat transfer loops where the exact 50 percent concentration aligns precisely with the targeted freeze protection curve and operational thermal requirements.
• Commonly applied in industrial thermal systems that require a stable propylene-glycol/water formulation for consistent freeze protection and reliable circulation.
• Commonly applied in industrial piping systems where a low-viscosity, pink dyed liquid helps trace fluid dynamics, monitor circulation rates, and quickly identify leaks at system joints.
• Commonly applied in heavy-duty automotive and industrial equipment that require an uninhibited, non-commercially suitable industrial liquid for thermal exchange without introducing corrosion inhibitors that might interfere with a custom additive package.

When to Choose a Different Grade

• If your facility requires a customized fluid ratio to achieve a specific, deeper freeze protection curve than a 50 percent mix provides, you should source the 100 percent concentration of Arctic Assist for precise on-site dilution.
• If the operational environment demands active multi-metal corrosion protection in a mixed-metal closed loop over an extended timeline, you will need to specify a heavily inhibited version of Arctic Assist rather than this baseline uninhibited formula.
• This fluid is built on a USP-grade propylene glycol base and is low in toxicity, which is why propylene-glycol coolants are common around food, beverage, and pharmaceutical facilities. It is not, however, an NSF-registered or food-contact-certified product (it is dyed and intended for closed-loop use) — for direct or intended food contact, specify a fluid explicitly certified for that application.
