Identify the exact model
LM-9B, LM-9D and LM-9E have different operating limits and material requirements. A family-wide temperature envelope does not describe a single fluid.
Heat transfer fluids
LM-9 series
Wide-range organic heat transfer fluids
Anhydrous, bidirectional heat transfer fluids for processes that alternate between cooling and heating. Each model has its own operating envelope and compatible materials.

LM-9 series catalogue reference values (Table 10)
| Model | Temperature range (°C) | Freezing point (°C) | Boiling point (°C) | Flash point (°C) | Viscosity (cP) | Density (g/cm³) | Specific heat (cal/g·°C) | Thermal conductivity (W/m·K) |
|---|---|---|---|---|---|---|---|---|
| LM-9B | −25 to +270 | −54 | 285 | 135 | 6.66 | 1.035 | 0.378 cal/(g·°C) = 1.58 kJ/(kg·K) | 0.133 |
| LM-9D | −75 to +150 | −90 | 175 | 62 | 1.18 | 0.901 | 0.448 cal/(g·°C) = 1.87 kJ/(kg·K) | 0.135 |
| LM-9E | −50 to +240 | −55 | 253 | 114 | 2.35 | 0.881 | 0.488 cal/(g·°C) = 2.04 kJ/(kg·K) | 0.142 |
All properties are printed at 20 °C, and specific heat is printed in cal/g·°C (1 cal/g·°C = 4.184 kJ/(kg·K)).
Reference values from the Chaoyang Guangda LM catalogue — typical figures rather than guaranteed limits. Confirm the exact model and concentration on the current model TDS before specifying.
View source: catalogue p.23 (PDF p.27)Before you specify
Combustible fluids. The full family envelope is not available in one model. Clean and dry the system before filling and prevent moisture ingress.
FROM FORMULATION TO APPLICATION
Process heating and cooling, considered together.
The LM-9 references describe model-dependent duties in pharmaceutical, petroleum, chemical-engineering and research applications where a broad process window is required.
Prepare the system
The LM-9E reference calls for cleaning and drying before direct filling. Discuss residual water and existing-fluid removal as part of the changeover plan.
