FIRE SAFETY & SECURITY
NUAIRE RELEASES CPD ON HIGH TEMPERATURE AXIAL FANS & VSDS
Indoor air quality and ventilation manufacturing specialist Nuaire is pleased to announce its latest CPD , which addresses High Temperature Axial Fans & Variable Speed Drives ( VSDs ).
This new CPD has been introduced to clearly explain the standard ‘ BS EN 12101-3:2002 Smoke and heat control systems - Specification for powered smoke and heat exhaust ventilators ’, and advise on compliance .
Simon Plummer , Nuaire Axials Divisional Manager and one of the UK ’ s leading fire safety experts , has written the CPD to provide clarification : “ Frequency converters have been permitted for use during a fire event since 2015 , enabling dual mode fans ( those used for both day-to-day ventilation and high temperature smoke extraction ) to be controlled by VSDs , even during fires . Prior to this , the VSD had to be bypassed during a fire event , with the fan running at 100 %. However , there remains some confusion in the industry about how high temperature fans and VSDs can be certified and used for the various smoke applications within buildings . Our new CPD directly addresses this , explaining the standard in detail and the flexibility it offers Consultant and Smoke Designers when it comes to designing solutions .”
In addition to explaining the standard , the CPD covers the test conditions that high temperature axial fans and VSDs must undergo , before moving on to best practice in high temperature fan design . The importance of opting for a fan / VSD that has been tested as a package is stressed , along with an explanation of why a VSD “ Fire Mode ” ( smoke clearance function is needed .
As with all Nuaire CPDs , the High Temperature Axial Fans & VSDs CPD can be delivered free of charge at Nuaire ’ s head office in Caerphilly , South Wales , online via Teams , or at a customer ’ s premises . All those attending will gain full CPD credits and certificates .
