Linde Fire Extinguisher, the manual fire extinguisher which got recognition of fire extinguishing performance of Class A(General fires), B(Oil fires), and C(Electrical fires), is the high-performance premium product to be able to respond to various fires promptly and minimize corporate assets and human damage due to the characteristics of NOVEC1230™. Linde Korea tries to play a role of protecting customers' precious life and assets and creating safe environment with reliable products like this.

Solution

NOVEC1230™ used in Linde Fire Extinguisher has the electrically excellent dielectric behaviour in both of liquids and gas so that it is never damaged even though it is sprayed on electric equipment or electronic facilities.

It is helpful for stabilizing electricfields by reducing their strength.

The fire extinguishing agent is very less soluble in water.

Blocking high current is more excellent than other gas currently used because of higher insulation performance.

Toxic substances due to chemical reaction are not emitted.

It's the non-conductive material which is not electrifying.

Use

It is very multipurpose. Linde Fire Extinguisher can be applied to facilities with high equipment including computers, machines, information and communication facilities, electrical and electronics equipment rooms, clean rooms, etc. and all other places that fires of Class A, B, and C break out. It does not damage equipment and facilities even thought it is sprayed and there is no need of secondary work of cleaning foreign substances of fire extinguishing agents because they do not remain after being done.
