COVEN 649 Heat Transfer Fluids – 3M NOVEC 649 Replacement
Coven 649 belongs to the ketone fluoride group of compounds and is a clear, colorless, tasteless liquid. Typical applications include computer rooms, data centers, aviation, ships, vehicles, libraries, oil and gas production, etc. Its high safety, low environmental impact, and superior fire extinguishing performance make it an alternative to chemical halon fire extinguishing agents that provide a long-term viable, environmentally sustainable technology for special hazard fire prevention.
#3M NOVEC 649 Replacement
Features and benefits
- Features: colorless, odorless, good solubility, insoluble in water, good thermal stability, ODP value is zero, no damage to the ozone layer, low greenhouse effect value, low surface tension, small viscosity, small latent heat of evaporation, excellent material compatibility and fire performance, high safety.
- Advantages: Excellent environmental protection performance: the most stringent international environmental regulations; High fire-extinguishing efficiency: minimum extinguishing concentration: 3.5% for Type A fire, 4.5% for Type B fire, safe to use the extinguishing concentration is much lower than (NOVAL); Good electrical insulation: dielectric strength up to (3mm) 74.6 kV and has passed the electrical insulation performance test of 110 kV; Good cooling performance: unique cooling effect after discharge; No residue after use: volatilizes quickly after use, which will not cause damage to precision instruments, antique calligraphy and painting.
