Glacier Coolant LM-9E Industrial Secondary Refrigerant-50°C To 240°C

short description:

High Temperature Heat Transfer Fluid | -50°C to 240°C | Anti-Corrosion Industrial Coolant

✦LM-9E Glacier Coolant is a high-performance industrial secondary refrigerant (heat transfer fluid) designed for indirect cooling systems. It transfers cooling capacity generated by refrigerants to target substances in closed-loop systems.

It is widely used in chemical industry, pharmaceutical-related industrial processing, cold storage, and temperature-controlled systems, where stable heat transfer performance and long service life are required.

LM-9E contains no water and requires the system to be thoroughly cleaned, purged, and dried before filling. Prevent moisture from entering the system during use.

System Usage Guidelines

To ensure optimal performance:

• Use LM-9E as a single fluid; do not mix with other heat transfer media

• Ensure system is fully cleaned, purged, and dried before filling

• Avoid water contamination during operation

• Recommended use in closed-loop systems

• Nitrogen sealing is recommended to prevent moisture ingress

• Follow proper industrial installation standards

• Ensure the temperature difference between coolant freezing point and system minimum temperature is more than 10°C

• When actual viscosity exceeds 80 cP, consider selecting a lower viscosity model
