In the refrigeration field, coolants play a crucial role in indirect cooling systems by efficiently transferring cooling capacity. As "secondary refrigerants," they are widely used in the food, pharmaceutical, petrochemical, and cold chain industries. Especially in long-distance cooling transmission, the coolant is first cooled in the evaporator, and then cools the target objects, achieving efficient temperature control.

The commonly used coolants today include inorganic salt solutions and organic alcohols, such as methanol, ethanol, and ethylene glycol solutions, all of which are good-performing coolants. However, methanol and ethanol have low flash points and are volatile and flammable, posing safety risks. As a result, their use is rare. Ethylene glycol solution is the most widely used organic alcohol coolant, but it has low toxicity and irritant properties, is not easily biodegradable, and is therefore restricted in food and pharmaceutical applications.

LM-4B Glacier Refrigerant, developed by Glacier Group, is primarily composed of modified trihydroxy alcohols, with additives such as preservatives, fungicides, solubilizers, and water stabilizers. LM-4B refrigerant features a high specific heat capacity, with a specific heat of 2.61 kJ/kg·K at -20°C; low viscosity at low temperatures, with a viscosity of only 45.39 cP at -20°C; and a wide operating temperature range, making it a strong coolant. It can be used in a temperature range of -20°C to 95°C under different concentration conditions.

LM-4B Glacier Refrigerant is highly compatible with metals, providing excellent rust protection for carbon steel, copper, and stainless steel. In actual use, it does not cause corrosion to system equipment or pipes and does not result in leakage, reducing costs related to downtime, maintenance, and pipe replacements.

LM-4B Glacier Refrigerant is a very stable compound, and its aqueous solution is non-toxic, odorless, and non-volatile. It can directly contact food, making it widely used in food preservation and freezing. In systems, LM-4B circulates continuously, delivering cooling evenly throughout every corner, maintaining a relatively constant temperature and preserving food quality to the greatest extent.

With the increasing emphasis on food safety and drug quality, especially with the rise of emerging industries like e-commerce and fresh food delivery, the market demand for LM-4B Glacier Refrigerant continues to grow. In the future, Glacier Refrigerant will continue to focus on developing more innovative coolant products, advancing refrigeration technology, and contributing to green and sustainable development goals.
