The new modified monohydric alcohol antifreeze uses reverse triol synthesis technology along with advanced processing techniques such as high-frequency cavitation, constant-pressure distillation (double aldehyde removal), and high-shear emulsification. It also features optimized functional group recombination. This product is the first in the industry to incorporate rosin alcohol and kaempferol-12···
Application Areas
Immersion freezing & cold storage logistics & food industry, pharmaceutical and chemical engineering & life sciences & ultra-low temperature cryogenic systems, etc.
Physical & Chemical Properties
Non-toxic, high specific heat, non-corrosive, excellent thermal diffusivity
Temperature Range
-100℃—90℃
Precautions
1. Ensure the system is clean and free of impurities before injection; for large-scale systems, use an N₂-pressurized closed expansion circulation whenever possible.
2. When applied in open systems, a constant-temperature servo cooling circulation filtration system with temperature ≤0°C must be installed.
