LM-8 Series Secondary Refrigerant Technical Guide
LM-8 low-temperature water-based coolant and LM-9D high-temperature coolant - the versatile performer for low-temperature conditions, covering -50 to 120C wide temperature range.
The Versatile Performer for Low-Temperature Conditions
LM-8 is a water-based coolant designed by Glacier Coolant specifically for low-temperature conditions, with an operating temperature range of -50 to 120C. With excellent low-temperature fluidity, non-flammable and non-explosive safety characteristics, and a wide temperature coverage, LM-8 performs outstandingly in heat source towers, low-temperature cold storage, and industrial low-temperature refrigeration.
LM-9D is the high-temperature enhanced version of LM-8, with superior high-temperature performance in the -45 to 120C range, suitable for systems with higher high-temperature segment requirements.
LM-8Series Model Comparison
| Model | Temperature | Key Features | Typical Applications | Notes |
|---|---|---|---|---|
| LM-8 | -50 to 120C | Excellent low-temp performance, non-flammable | Heat source towers, low-temp cold storage, industrial refrigeration | Corrosion accelerates at 120C; avoid strong oxidizers |
| LM-9D | -45 to 120C | Wide range, superior high-temp performance vs LM-8 | Systems operating from -45 to 120C | Higher price; corrosion rate data available |
LM-8Series Key Advantages
Ultra-Low Freezing Point
-50C freezing point meets the vast majority of low-temperature refrigeration needs, far exceeding LM-4's -20C low-temperature limit.
Non-Flammable & Non-Explosive
Water-based formula, safe and environmentally friendly, no special fire and safety measures required.
Wide Temperature Coverage
-50 to 120C range, accommodating both low-temperature refrigeration and high-temperature conditions, suitable for heat pump dual-condition systems.
Material Compatibility
Compatible with carbon steel, stainless steel, and other common materials. Stainless steel recommended above 120C to slow corrosion.
High-Temperature Stability
Remains stable at 120C, suitable for heat source towers and other dual cold-hot condition systems.
Safety Protection
Avoid contact with strong oxidizers. Corrosion accelerates at high temperatures - regular monitoring required.
LM-8Series Real Cases
LM-8Series Usage Precautions
High-temperature corrosion: Corrosion accelerates at 120C; use stainless steel for high-temperature applications.
Strong oxidizers: Avoid contact with concentrated nitric acid and other strong oxidizers.
Shutdown protection: Temperature rise during shutdown causes thermal expansion; expansion tank or relief device must be installed.
Plate heat exchanger icing: Local icing may occur at low temperatures; cool gradually in steps to avoid icing.
