BestSolv™ Zulu Common Applications
BestSolv™ Zulu is used in a wide variety of industrial applications, both as a liquid and as a gas.
Fire Suppression
As a chemically identical Novec™ 1230 replacement, BestSolv™ Zulu offers the same clean agent fire protection advantages as its Novec™ counterpart. BestSolv™ Zulu extinguishes fires in seconds, long before water-based systems discharge. As a waterless fire suppression solution, BestSolv™ Zulu leaves no residue and helps protect irreplaceable paper documents and electronics.
- Stored as a liquid and discharged as a gas
- Appropriate for Class A, B and C fire hazards
- Provides the highest margin of safety for human occupancy of any clean agent solution under the NFPA 2001 standard.
Immersion Cooling – Heat Transfer Applications
This chemically identical Novec™ 649 replacement is an effective heat transfer fluid with a boiling point of 49 ºC. BestSolv™ Zulu is especially useful in heat transfer, electronics cooling and thermal management applications where non-flammability or environmental factors are a concern.
Application examples include:
- Electronics cooling (single or dual phase)
- Power electronics such as IGBTs or inverters
- Transformers and other equipment (SF6 replacement)
- Immersion cooling for data centers and computers
- Organic rankine cycle
- Diesel engines
- Generators
- Geothermal applications
- Solar applications
