NOFIRNO systems are used to seal cable ducts in an extensive range of Process industry sectors including the fine and speciality chemicals, petrochemicals, pharmaceuticals, hydrogen and polymers manufacturing sectors.

The NOFIRNO range of duct seals are used to protect against water ingress, gas migration, fire spread and rodent infestation into electrical substations and buildings through LV MV HV cable ducting systems.

Comprised of rubber and filler sleeves and sealant, the system is used to treat transit openings for cables and pipes in walls, floors, bulkheads or decks, so that they are fire-resistant and sealed against gas, smoke and water. Kiwa’s research has shown that NOFIRNO is extremely suitable for use in environments such as those covered by the ATEX directive and described in the European standard EN 1127-1 ‘Explosive atmospheres – Explosion prevention and protection – Part 1: Basic concepts and methodology’.
