smoke control fans facilities I nuaire

testingfacilities• Nuaire has one of the foremost testing

facilities in the world.• Nuaire utilise ‘state of the art’ technology,

with separate testing facilities (ducted – type C, & D and open inlet – type A)

• Nuaire’s laboratories have the capability to carry out acoustic tests to BS848 part 2 and AMCA 300.

• Nuaire have a long standing relationship with BISRA (Building Services Research & Information Association), who choose to utilise Nuaire’s facilities for their own independent testing.

• Nuaire test all of their electrical products in-house for EMC (Electro magnetic compatibility).

• Nuaire’s team of technicians and test engineers have a wealth of knowledge gleaned from years of extensive acoustic andaerodynamic development and testing.

• Nuaire can advise you on the best solution possible for your requirement.

• Nuaire offer a ‘factory witness testing facility’for your and your client.

smokecontrolShopping Centres & PublicBuildings: Safe EscapeThe main benefits of installing NuAire SmokeControl Systems are:• Safe escape for occupants• Safe entry for fire fighters• Reduced smoke damage• Reduced water damageNuAire fans provide a smoke ‘clear layer’ to allowbuilding occupants to safely escape from abuilding during a fire situation.

Commercial & Industrial Buildings:Safe Escape & Protecting GoodsIn addition these systems allow fire fightingservices to safely enter the building, to locate thefire and maintaining a clear layer helps prevent‘fire damage’ to stored goods or machinery.

Pressurisation of Escape RoutesBS5588 Part 4: specifies the use ofpressurisation for the means of escape.The systems ensure that stairs and corridors inmulit-storey buildings remain clear of smoke.

BS5588 Part 5: specifies the use ofpressurisation for fire fighting systems. Inaddition to providing safe means of escape,these are designed to offer safe access to firefighters.

Nuaire pressurisation run & stand by fans arespecially designed to meet the requirements ofthese standards.

Shopping Centres & Car Parks: Safe EscapeThrust Vent offers efficient daily ventilation forCO removal, smoke clearance and smokecontrol.

The system provides active cooling of thesmoke, creation of virtual smoke barriers, easyvisual location of the fire for emergency servicesand quick, efficient extinguishing of the fire.

As from April 2005 it is mandatory for allemergency smoke ventilation equipment for usein the EU to be independently tested in anaccredited test facility and certified by theappropriate notified body (BSI)** to ensure itssuitability for the purpose.All such equipment must be independently tested to BSEN12101-3:2002 Smoke and heat control systems.Specification for powered smoke and heat exhaust ventilators.

Nuaire’s Axus range of high temperature fans and ancillarieshave been tested at BSRIA* in accordance with the abovestandard, ensuring your system meets these stringentrequirements.

Nuaire, through their partners Airvent Systems, can offer acomplete smoke ventilation solution for car parks & buildingsin general from initial conceptual discussions right throughthe design, installation, commissioning and handover stages.

Nuaire’s comprehensive high temperature range includes -• Up to 1600mm diameter• 3000C for 2 hours• 4000C for 2 hours

The Impulse system • Energy efficient – By monitoring the air quality and

operating the system at optimum level the overall motor power and running costs can be reduced by up to 40%

• Space saving by up to 40% – Low depth unit eliminates the need for ducting, maximising car park space availability

• Full design & installation service – An experienced technical team offer design, supply, installation & commissioning to suit your project requirements

• Quiet systems – Unit has inlet and outlet silencersensuring low noise levels are maintained

• Cost savings – Less ductwork can typically reduce costs by up to 30%

• Safety tested – All equipment is tested to EN12101-3, 3000C for 2 hours

• Fully reversible option – Flexible directional flowresponds to any fire location

• Quick and easy installation - Unique mountingbracket allows for 2 stage, ‘quick’ installation

• Warranty – AXUS Impulse range has a 3 year warranty

*BSRIA – the Building Services Research and Information Association operate the only UKAS Accredited facility in the UK to test to EN 12101-3. (www.bsria.co.uk )**BSI – the British Standards Institution, is the UK notified body under the Construction Products directive, under which compliance with this standard requires typetesting and approval and monitoring of the factory production control systems. (www.bsi.co.uk)

The car park impulse system is used to control and remove contaminants on a day to day basis, whilst ensuring that smoke isremoved quickly and efficiently in the event of a fire. The systems utilises a number of strategically positioned impulse fans, mountedon the ceiling, that push the fumes and smoke towards a designated point of exhaust. This in effect compartmentalises the smokestream ensuring quick and effective clearance whilst keeping the rest of the car park smoke free. This removes the need forcomplicated ductwork systems and optimises space.

How the system works


The system runs at low speed ensuring that Carbon Monoxide levelsand other contaminants are kept within acceptable limits. Strategicallyplaced detectors monitor the air and control the units which can directlyeffect the condition.

Smoke detectors throughout the car park identify the units which canmost effectively contain the smoke layer and increases the fan speed tomaximum, the main exhaust unit is also switched to maximum.

A fire starts in one of the vehicles and smoke starts to spreadthroughout the car park, the smoke detection system identifies thesituation and the fire alarm system will be activated.

The smoke layer is contained and directed towards the main extractunit, where the smoke can be safely exhausted to atmosphere. Thismaximises the space within the car park, keeping large areas clear ofsmoke, enabling the area to be quickly and safely evacuated.

Car park impulse system specification

The car park ventilation system shall control and remove pollutants,such as Carbon Monoxide, on a day to day basis, whilst ensuringthat smoke is removed quickly and efficiently in the case of fire.

The car park Impulse Ventilation System shall consist of a number ofstrategically positioned acoustically treated Impulse fans distributedthroughout the car park, the positions shall be in accordance withthe specialists design & layout drawings.

Carbon Monoxide & smoke detectors shall be strategically placed inaccordance with the specialists design and shall control theoperation of the impulse fans in individual areas appropriately. Bycontrolling the fans in this way the impulse fans will containpollutants and smoke within a defined & predetermined corridor andchannel its flow to the extract point where it can be evacuatedsafely to atmosphere by the main exhaust fan unit. The controlsystem ensures that only the fans that can directly effect theventilation requirement are in operation.

The Nuaire SVT impulse unit comprises a high temperature axial fan with specially designed inlet and outlet attenuators which, alongwith the fan unit, are encased in a Galvanised steel acousticenclosure.

The Nuaire SVT unit comprising fan/motor assembly, and inlet &outlet silencers shall be certified for high temperature operation at3000C for 2 hours, the range shall have been type tested toEN12101-3.The Axus Main exhaust unit and ancillaries shall havebeen type tested and certified for high temperature operation at3000C for 2 hours to EN12101-3.

The units shall be either 2 speed or inverter driven providing, low speed for day to day environmental extract and one offoperation for emergency extract. They shall also be suitable forreversible operation.

Fully reversible options (i.e similar duty in both airflow directions) areavailable, please contact Nuaire for details.

The unit shall have a unique mounting bracket, which shall enablethe bracket to be positioned as a “first fix” component with the unitbeing fitted as a “second fix” component, avoiding possiblemechanical damage.

The Nuaire SVT unit shall have inlet guards for safety purposes andalso to prevent debris being sucked through the fan. It also has aspecially designed airflow deflector to direct the jet stream from thefan at the required angle sufficient to overcome the naturalbuoyancy effect of the smoke.

The car park impulse units shall be the SVT type and the main Exhaust unit shall be the high temperature AXUS type all as manufactured by Nuaire.
