The five core functions of antifreeze

1. ‌antifreezeIn low temperature environments, antifreeze can significantly lower the freezing point (up to -45 ℃ or even lower), prevent the cooling system from freezing and expanding, and prevent the water tank or engine cylinder from freezing and cracking.

2. ‌Anti boilingThe working temperature of the engine often exceeds 90 ℃, and the boiling point of antifreeze is usually above 108 ℃, much higher than the 100 ℃ of water, which can effectively prevent the phenomenon of "boiling".

3. ‌anti-corrosion and anti-rustThe cooling system contains various metals such as iron, aluminum, copper, etc. The corrosion inhibitor in the antifreeze can form a protective film to prevent metal parts from corroding and rusting, extending the engine life.

4. ‌scale-proofOrdinary water is prone to scale formation, which can block the heat dissipation channels. Antifreeze is prepared with deionized water and added with scale inhibitors to keep the cooling system clean and unobstructed.

5. ‌Annual useMany people mistakenly believe that antifreeze is only useful in winter, but in fact, it works all year round, with heat dissipation in summer and antifreeze in winter being indispensable.

9. ‌Ultra low freezing point protection‌
   Cold storage often operates below -18 ℃, and ordinary water will quickly freeze and expand, causing pipeline rupture. Antifreeze can lower the freezing point by adding components such as ethylene glycol or propylene glycol-45 ℃ or even -50 ℃Comprehensively resist the risk of low temperatures.

10. ‌Efficient heat transfer and fluidity‌
    High quality antifreeze maintains good fluidity at low temperatures, avoiding the impact of increased viscosity on circulation efficiency, ensuring rapid transfer of cooling capacity, and improving the operational efficiency of refrigeration systems.

11. ‌Long term anti-corrosion and anti scaling measures‌
    Long term operation of the cooling system is prone to metal corrosion and scale deposition. Corrosion inhibitors and scale inhibitors in antifreeze can form a protective film to prevent corrosion of metal components such as iron, copper, and aluminum, and extend the life of key components such as water pumps and heat exchangers.

12. ‌System compatibility and security‌
    Suitable for various metal pipelines, rubber seals, and plastic components, without swelling or aging. Some environmentally friendly products use low toxicity and biodegradable formulas, which meet the high hygiene requirements of scenarios such as food and medicine.

Common types and selection suggestions

• ‌Ethylene glycol type (mainstream choice)‌
  The freezing point can reach -60 ℃, with good thermal conductivity and moderate price. It is widely used in industrial cold storage, cold chain units and other systems.

• ‌Propylene glycol type (environmentally preferred)‌
  Low toxicity, biodegradable, suitable for scenarios with high safety requirements such as food processing and pharmaceutical cold chain, but with high cost.

• ‌Concentrated solution vs premixed solution‌

• Concentrated solution needs to be mixed with water in proportion (such as 30% -60% concentration), which has high flexibility but requires precise proportioning;

• The pre mixed liquid has been prepared and can be used immediately after opening the lid, suitable for users who prioritize maintenance convenience.

Key points for use and maintenance

• ‌Ice point matching environmentWhen choosing antifreeze, its freezing point should be at least 10 ℃ lower than the working temperature of the cold storage, leaving a safety margin.

• ‌Regular testing and replacement: Suggest every2-3 yearsOr replace it once according to the manufacturer's instructions; If turbidity, precipitation, pH decrease (<7.2) or odor occurs during use, it should be replaced in a timely manner.

• ‌Prohibit mixing different modelsMixing antifreeze solutions with different chemical formulas may result in precipitation or failure. When replacing, the old solution should be emptied at the bottom.
