GAS-TIGHT SECTIONAL DOORS
Gas-Tight Sectional doors FIDELITY hydraulically powered, with special sealings. Sealing guarantee given by the FIDELITY system.
The GAS-TIGHT performances are those of granting a limited passage of air through the door, at closed door.
The GAS-TIGHT sectional overhead door is lifted by the hydraulic Fidelity mechanism that eliminates the balancing springs, and consequently all periodical maintenance changes in a simple inspection.
The Fidelity system grants that the whole weight of the door leaf is in contact by the gravity force, without any balancing.
This natural force allows a contemporary compression of the whole door when closing, against the perimeter sealings and the bottom astragal, assuring in this way the Gas Tightness.
Conform to the Product Norm EN 13241. Marked CE
