Mechanical Smoke Ventilation
Mechanical Ventilation
Regardless of the structure and constraints of the available building space, Caledonian Smoke Vent Systems Ltd offers a range of solutions that can be tailored to meet all specifications This includes mechanical extraction systems which can facilitate the need for smaller openings and a narrower shaft space, releasing valuable rentable floor space.
We can provide mechanical smoke ventilation systems designed as an alternative solution to ADB and BRE smoke shafts. Mechanical solutions can offer reduced smoke shaft sizes (typical 0.6m² versus 1.5m² or 3m²) increasing the lettable areas in a development. In addition, a mechanical system in conjunction with CFD modelled fire engineered solutions, offer increased escape travel distances reducing the need to include additional stair cores. This type of system has been designed for both means of escape and fire fighting operation with occupants and fire & rescue service safety to the fore.
The SE Controls Variable Speed Fan Control Panels are a fixed modular design that are built and tested to provide a method of operating a single 415V three phase 50HZ duty/standby fan arrangement. The information pack must be retained for future reference by the client and be made available for reference by persons installing, servicing or modifying the panel. Application: The Variable Speed Fan Control Panels are a control system designed to operate 415V3PH/50Hz fans in a duty and standby configuration for smoke control in a powered extract system. The control of environmental fans is also possible when specific additional packs are fitted. Operating from a 415 Volt supply, the Variable Speed Fan Control Panels can control fans up to 11kW (Standard Versions).
Controllers / 415V 3Ph/ 50Hz
The Fan Control Panel has the following features:
- Industrial PLC logic driven system
- Optional built in ACOPS
- Duty fan and standby fan control
- Multiple fan speed control via industrial inverter enabling fire fighting and/or means of escape operational mode
- External fire fighters key switch control (auto/off, auto/boost)
- Simple hard wired activation or more involved network signal activation
- Multiple panels can be networked together creating highly specialised multiple fan operation for multiple shafts
- Reversible fan operation if required for twin shaft/triple shaft push/pull systems
- Pressure sensor monitoring to prevent excessive negative pressure in the activated zone
- Ability to power separate fans from main duty/standby fans for day to day ventilation operation
- Ability to power additional single phase or three phase NV fans
- Ductwork damper(s) control • System state indication on panel face via LED’s
- Activation/healthy vfc’s for BMS monitoring
- Fan panel status can be viewed via associated SHEVTEC repeater panel Applications Environmental Ventilation Smoke Ventilation
