Ultra-Low Temperature Eco-Friendly Organic Salt Coolant LM-8 Series
Product Introduction
LM-8 is optimized for imported potassium formate-based ultra-low temperature heat transfer fluids. Its performance and operating range are fully comparable to the HC series of cryogenic heat transfer media. It operates stably in closed systems from -50°C to high-temperature conditions and provides excellent corrosion protection for carbon steel, stainless steel, copper and other metals. LM-8 requires no system modifications and is suitable for harsh environments such as industrial cryogenics, cold chain logistics, food freezing and reactor cooling, delivering higher cost-effectiveness at equivalent performance.
Glacier Coolant LM-8 is an industrial-grade ultra-low temperature coolant developed using modified organic salt technology. It serves as a high-performance, environmentally responsible alternative to traditional calcium chloride brines, offering low viscosity, high thermal conductivity, and reliable stability under extreme cold conditions.

LM-8 provides outstanding corrosion protection for common industrial metals such as carbon steel, stainless steel, and copper. Its high specific heat and thermal conductivity ensure efficient cooling capacity transfer even in ultra-low temperature applications, reducing pump energy consumption. Complying with international safety standards, LM-8 is not classified as hazardous, has no flash point, is non-flammable, and exhibits low volatility, enhancing operational and transport safety.
Ideal for pharmaceutical cold storage, chemical process cooling, food freezing, ice sports facilities, brewery operations, new energy battery testing, and aerospace applications, LM-8 is designed for standalone use to maintain system integrity. Regular pH monitoring is recommended, along with bi-annual sample testing at the Glacier Coolant R&D Center to ensure consistent performance.
