Is the chimney currently in use okay?
The Hi-jet ARC method involves suspending the Hi-jet ARC removal device from the top of the chimney, allowing for a removal process that uses ultra-high pressure water while keeping the interior of the chimney unmanned. The device is lowered and raised as needed by an operator remotely, facilitating the removal process. 【Features】 - Unmanned remote water pressure cutting removal inside the chimney - Minimal dispersion of asbestos dust due to water removal - The water used is limited to the minimum necessary, similar to household tap water - Removal of not only liner-equipped chimney insulation but also hard lining materials such as asbestos cement cylinders in a single process - Cutting, washing, and removal of deteriorated areas such as asbestos fibers embedded in the concrete inner surface of the chimney and honeycombing - Maintains a negative pressure ventilation rate of 40 times/hour, countering chimney draft (updraft) - The work floor in the isolation area is waterproofed with construction-grade waterproofing materials, preventing leaks - Capable of removing chimneys that have collapsed and deformed during construction, as well as those with bends - Vibration is almost nonexistent compared to mechanical cutting removal, preventing damage to the chimney and buildings - The time required for removal is short, significantly reducing the construction period - Accommodates a wide range of chimney diameters from 130 mm to 3,500 mm *For more details, please feel free to contact us.

basic information
- The interior of the chimney is remotely cut and removed using water pressure, with no personnel inside. - Since removal is done with water, the dispersion of asbestos dust is very minimal. - The water used is only the necessary minimum, similar to household tap water. - Hard lining materials such as asbestos cement cylinders, as well as chimney insulation with liners, can be removed in one process. - Asbestos fibers and deteriorated areas like honeycombing that have penetrated the concrete on the inner surface of the chimney are also cut, cleaned, and removed. - A negative pressure ventilation rate of 40 times per hour is maintained, which does not lose to the chimney draft (updraft). - The work floor in the isolation area is waterproofed with construction waterproofing materials, ensuring no leakage. - Chimneys that have collapsed and deformed during construction, as well as those with bends, can also be removed. - Vibration from mechanical cutting removal is almost nonexistent, preventing damage to the chimney and the building. - The time required for removal is short, significantly reducing the construction period. - The chimney diameter can accommodate a wide range of sizes from 130 mm to 3,500 mm. - Confirmation of removal inside the chimney is done remotely using monitoring cameras and other devices. - Dioxin-contaminated materials that adhered during the operation of waste incinerators can also be cut and removed simultaneously. - Contaminated water is treated with special absorbent agents and packaged in bags like the removed asbestos materials, with no discharge of treated water. ● For more details, please contact us or download the catalog.
