Water-Free Coolant Technology Benchmark
The LM-11 series is the water-free coolant family of Glacier Coolant, designed specifically for water-sensitive processes. From the LM-10A -25C water-free alcohol-free type to the LM-11F -85C ultra-low temperature water-free type, it covers a wide range of water-free operating condition needs.
The core advantage of water-free coolants is the absence of water, avoiding ice blockage caused by water molecule freezing at low temperatures. However, the system must strictly prohibit water, requiring nitrogen blanketing to prevent airborne moisture ingress. After water ingress, physical separation + molecular sieve drying is required.
LM-11Series Model Comparison
| Model | Temperature | Key Features | Typical Applications | Notes |
|---|---|---|---|---|
| LM-10A | Above -25C | Water-free and alcohol-free, for water-sensitive processes | Chemical process cooling | Cannot guarantee completely water-free; lead time and price may vary |
| LM-11D | Above -60C | Water-free, relatively low low-temp viscosity | Ultra-low temp chemical reactor cooling | System must be strictly water-free; nitrogen blanketing required; after water ingress: physical separation + molecular sieve |
| LM-11F | Above -85C | Ultra-low temperature water-free | Ultra-low temp reactor cooling | Lower thermal conductivity; note heat exchange changes when replacing LM-1; water-prohibited |
| LM-11C | - | Water-free coolant | Chemical reactor cooling | Valves must not be fully closed; maintain tank connection; temp changes cause high pressure |
LM-11Series Key Advantages
Water-Free Formula
Contains no water, avoiding low-temperature icing and blockage. System requires nitrogen blanketing to prevent airborne moisture ingress.
Ultra-Low Temperature Capability
LM-11F reaches -85C, meeting extreme low-temperature reactor cooling needs. LM-11D covers above -60C.
Low Viscosity
Relatively low low-temperature viscosity with better pump performance than some competitors. But specific heat and thermal conductivity are lower than water-based types.
Chemical Stability
Chemically stable under ultra-low temperature conditions, no decomposition or degradation.
Water-Prohibited Leak Testing
Use dry nitrogen for pressure leak testing. Water testing is strictly prohibited.
System Modification
When replacing water-based coolant, evaluate pipe, pump, and heat exchange area modification requirements.
LM-11Series Real Cases
LM-11Series Usage Precautions
Strictly water-free: System must be strictly water-free; nitrogen blanketing required to prevent airborne moisture ingress.
Water ingress treatment: After water ingress, use physical separation (let stand to stratify, collect upper layer) + molecular sieve drying.
Filter: Install filter before pump; clean regularly based on operating current.
Leak testing: Use dry nitrogen for pressure leak testing. Water testing is strictly prohibited.
Replacement notes: When replacing water-based coolant, pipes must be enlarged, flow doubled, and heat exchange area increased by 1.5x.
