FIRE RESISTANT
In order to cater to varying levels of fire resistance in line with various domestic and international standards, Jonson has developed range of fire resistant belts which we promote as Jonson Fire Resistant (JFR). This range includes belts suited for underground use and specialized belts with low smoke & toxicity .
Fire Resistant belts commonly used in handling coal over ground in coal mines, thermal power plants and in underground coal mines. Fire Resistant belts are similarly used for conveying other materials which are prone to ignition during use.
Benfits
- Reduces the risk of fire hazard and potential loss to human life, material and installation.
- Fire resistant belts are Anti-Static.
- Easy to splice or require using standard materials.
Product Application
Coal Mines and other underground mines, Thermal Power Plants, Coal Handling units, Sulphur Conveying etc.
Fire resistant belts with added feature of heat and /or Oil Resistant property are also available on request.
