Life just got easier for developers, designers and regulators of residential and student accommodation thanks to SE Controls’ revolutionary approach to smoke ventilation. After a flawless installation of their SHEVTEC Extended Travel Distance Systemat Chettles Yard student accommodation in Nottingham, their client has been able to benefit from themost cost effective and robust smoke ventilation systemin themarket.
significant costs in a number of ways. The system enables escape travel distances to be increased above the ADB compliant maximum 7.5m without the need for additional stairwells, creating an opportunity for significantly more accommodation. Furthermore, the SHEVTEC Extended Travel Distance System uses smoke shafts less than half the area required by a conventional 1.5sqm shaft demanded under a typical natural ventilation system, as set out in Approved Document B of the Building Regulations. This is achieved through using fans tested to EN12101-3 and suitable for smoke ventilation to increase

he SHEVTEC Extended Travel Distance System enables designers to save
Travel Distance System’s OSLoop Control intelligently monitors the system, such that if one extract shaft fan fails to operate it will automatically bring alternative shafts into extract mode. This creates significant cost savings as each shaft only requires one single phase fan served by an independent supply, which can be neatly housed in the top of the shaft alleviating the need for the installation of roof mounted hefty, three phase fan sets requiring specialist access both for installation and maintenance. All SHEVTEC maintenance can be performed from the inside of the building. The system is the culmination
of over two years research using extensive Computational Fluid Dynamic (CFD) modelling to simulate literally hundreds of scenarios. The SHEVTEC Extended Travel Distance System has been designed to provide developers with much more flexibility to achieve ever increasing commercial pressures but without the need to
compromise occupant or fire fighter safety. Following SE Controls’ successful and smooth delivery of their turnkey solution in Nottingham, including the installation, commissioning and demonstration, SE Controls now know that their SHEVTEC Extended Travel Distance System is a major step forward for both them and their clients. SE Controls drew on 30 years
of experience of designing, installing and maintaining smoke and heat exhaust ventilation systems (SHEVs) when they designed LABC Registered SHEVTEC Extended Travel Distance System. System flexibility, repeatability and ease of installation were central to meeting the cost constraints demanded by current market conditions. But importantly this was achieved through innovation which has enhanced the quality of the system, with all components being CE marked to the current EN12101 SHEVs standards or in the case of the OSLoop control system, fully compliant with the imminent EN 12101 parts 9 and 10. SE Controls can offer various
options for smoke shaft AOVs including their SHEVTEC Smoke
Shaft Door and Actuator, tested to BS 476-22:1987, BS 1634-1:2000, BSEN 1363-1:1999, BSEN 1364- 2:2000 and to the principles of EN12101-2:2003 Annex G, giving designers the ability tomatch the AOV to other doors in the development. Alternatively SE Controls can deliver their SHEVTEC damper,which can be concealed behind a neat grill. Other Automatic Opening Vents are available in SE Controls SHEVTEC range including glazed louvres for end of corridor applications, casement smoke vents, 90 degree and 140 degree opening vents and smoke louvres for top of stair or
smoke shaft applications.
