A pressurization system consists of three main components:
A pressurization system for smoke and fire ventilation should meet the recommendations of:
WHAT WE OFFER
1. STAIR CASE PRESSURIZATION
2. LIFT-SHAFT/LIFT-WELL PRESSURIZATION
Elevator shaft pressurization is required to protect the shafts from ingress of smoke. Thereby, it restricts smoke spread to other floors connected to the shaft.
Smoke extraction systems are designed complying with the following codes: NFPA 92, NFPA 204, BS 7346 Part 4, other international codes of practice, and local authority regulations.
CORRIDOR SMOKE EXTRACTION SYSTEM
Corridors are provided with a mechanical smoke purge system. The intent of a smoke purge system is for the clearance/removal of smoke during evacuation and firefighting operations. Make up air shall be adequately supplemented based on the total smoke extract capacity.
STATIC SMOKE EXTRACTION SYSTEM
A smoke extraction system utilizing smoke reservoirs; localized ducting; and permanent openings and / or automatic opening of windows, panels or external louvers actuated by smoke detectors; to remove, on the principles of natural ventilation.
DYNAMIC SMOKE EXTRACTION SYSTEM
A mechanical ventilating system capable of removing smoke and products of combustion from a designated fire compartment, and also supplying fresh air in such a manner as to maintain a specified smoke free zone below the smoke layer. detectors; to remove, on the principles of natural ventilation.
