System Usage Guidelines
To ensure optimal performance:
• Use LM-9D 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
