Multi-Metal Heat Transfer Fluid Specially Engineered for Aluminum Component Protection
DynaGuard is an ultra premium, high-purity industrial heat transfer fluid formulated with a specialized, phosphate-free glycol corrosion inhibitor package. Engineered specifically for the rigorous demands of the food industry, it works better than the competition in complex, modern hydronic loops, HVAC systems, and industrial process cooling setups. This advanced 100% virgin propylene glycol fluid provides elite burst and freeze protection without the structural risks associated with traditional formulations.
While conventional, phosphate-based glycols can form destructive mineral scales in hard water and struggle to protect sensitive non-ferrous metals, DynaGuard features a next-generation PDT corrosion inhibitor additive package. This unique chemistry is highly stable under extreme temperatures. Its advanced PDT chemistry ensures a very slow inhibitor depletion rate (virtually non-depleting) resulting in a significantly extended fluid life that matches or exceeds traditional fluids without the need for periodic boosting.

Next Generation Multi-Metal Phosphate-Free Stabilization
In contemporary commercial facility design, engineering specifications increasingly dictate the use of high-efficiency aluminum heat exchangers and multi-alloy components. Traditional HVAC glycol fluids rely heavily on inorganic phosphates, which can aggressively attack aluminum surfaces under high-temperature fluctuations and cause accelerated pitting or scale fouling. DynaGuard directly addresses this engineering requirement by utilizing a non-reactive, phosphate-free inhibitor system that maintains absolute chemical stability and heat transfer efficiency over extended operational life cycles.
If your system features a traditional, heavy ferrous design (such as all-steel or all-cast-iron networks) where industrial phosphate chemistry is preferred, please visit our standard high-volume processing line on the Dynafrost Inhibited Propylene Glycol Based Heat Transfer Fluid product page.

How to Use & System Dosing
-
System Preparation & Flushing: Before charging a closed loop with DynaGuard, the entire system should be thoroughly flushed to remove loose rust, particulate debris, and old chemical residues. Residual scale or old fluid components can compromise the efficiency of the new inhibitor matrix.
-
Water Dilution Standard: For optimal long-term multi-metal protection, it is strongly recommended to dilute DynaGuard using distilled, deionized, or ultra-pure soft water. High concentrations of calcium and magnesium found in hard tap water can react with components, even though the formula is phosphate-free.
-
Determining Your Target Dosing Ratio:
- For freeze protection down to -15°C, utilize a minimum recommended concentration of 30% DynaGuard to 70% water.
- For comprehensive sub-zero commercial burst protection down to -51°C, dilute to a configuration of 50% DynaGuard to 50% water.
-
Routine System Testing: Check the fluid concentration annually using a calibrated refractometer, and monitor the inhibitor reserve alkalinity using a multi-metal test kit to ensure ongoing corrosion defenses remain completely optimized.
*Generally, for an extended margin of protection, you should select a solution temperature that is at least 3°C (5°F) lower than the expected lowest ambient temperature.
**Inhibitor levels should be adjusted for solutions of less than 30% glycol.

FAQ
What is the difference between DynaGuard and traditional inhibited propylene glycols like Dynafrost?
Traditional fluids like Dynafrost utilize heavy phosphate-based inhibitor packages, which are exceptional at protecting standard iron and steel systems but can cause scale fouling and surface degradation when they react in systems with aluminum components. DynaGuard uses an advanced, phosphate-free inhibitor matrix designed specifically to protect sensitive multi-metal layouts, including modern aluminum heat exchangers.
Can DynaGuard be safely mixed with existing glycol fluids in our HVAC system?
Mixing different brands or chemical profiles of inhibited glycols is generally discouraged. Mixing a phosphate-free fluid like DynaGuard with a traditional phosphate-based fluid can destabilize the specialized inhibitor package, lowering your system’s overall protection. For optimal multi-metal protection, the system should be completely drained and flushed before installing DynaGuard.
Is DynaGuard compatible as a replacement for products like Chemfax Chem-Frost or Rhomar Rhogard?
Yes, absolutely. DynaGuard was engineered with the same advanced, phosphate-free approach to multi-metal safety as Chem-Frost and Rhogard. It serves as an excellent, direct-replacement solution for engineering specifications that explicitly call for non-phosphate, aluminum-safe propylene glycol heat transfer fluids.
