The upgraded models of the Qube, which are available in AC as well as EC, is our most popular set of centrifugal box fans and come with significant design enhancements that make them easier to install and maintain. The new EC variants offer better energy efficiency and performance, as well as control and integration into building management systems.

Meanwhile, the restaurant market is showcasing signs of resilience against the widely expected post-pandemic downturn, and new ventures and smaller venues are being planned by big restaurant chains. According to Lumina Intelligence’s Operator Data Index, the UK restaurant market reached valuation of £18.6bn in 2023, with a 4.4% growth rate in the same period.

David Millward, Group Product Manager at Elta Group, said: “We’ve been listening to feedback from our customers and also looking closely into the hospitality and restaurant market, and can see that there is a gap for high quality, long-lasting, energy efficient ventilation equipment in the commercial kitchen space.

“That’s why we’ve honed the design and features of our already well-received Qube centrifugal box fans. Our newest models are designed to meet the needs of specifiers and contractors working on designing and fitting new commercial kitchens, able to fit into ever-tighter footprints while still being able to offer the high extraction and performance expected from our fans.”

The Qube fans are suitable for extracting air up to 120°C in temperature. They come in various box sizes of 500, 670, 820, and 1,020mm. The fan’s box panels are double skinned with an infill to reduce noise transfer, and the panels are interchangeable to support quicker, simpler installation and to access the fan components inside for maintenance. The units as a whole are lighter and balanced to also help contractors with carrying and fitting the fans.

A key feature on the new Qube range is that they now have redesigned connections to connect the fans to other ventilation ancillaries, such as bolt-on filter boxes, making them more adaptable and flexible. Meanwhile, all the fan’s components are now enclosed within the box, whereas previous models of the Qube had the fan motor outside of box. This further helps with space and kitchen configurations where space might be limited.

We have also introduced new gas interlock systems alongside the Qube. Gas interlock systems provide a failsafe by limiting the gas flow to appliances until the ventilation system is on, and is a mandatory requirement in commercial kitchens.

Besides being ideal solutions for commercial kitchens, the Qube fans can also be used in general buildings and ventilation extraction, such as in offices, schools and industrial buildings.

David said: “We know everybody is paying a much closer eye to reducing energy usage in a bid to be more sustainable and lower their operational expenses. Our EC versions of our Qube fans help with this objective, allowing operators to commission the fans so they move and extract air efficiently.

“Besides our standard versions, being a UK manufacturer with our various plants and factories across the country, we are well positioned to provide a quick turnaround on our fans, and for those specifying ventilation systems for kitchens, we provide everything under one roof to simplify the purchasing process. We can also customise the Qube fans, ancillaries, and controls to suit bespoke needs. Simply talk to us and we can come up with a solution to fit the project.”

The £28 million student accommodation scheme called ‘The Gateway’, has provided 458 apartments and retail, restaurant and office spaces in Block A and an eight storey building, Block B, will accommodate 77 student apartments.

Elta, Senior Technical Sales Engineer, Toby Worrall said: “The design schedule for these contracts stressed the importance of a number of factors, including noise and optimised performance capabilities through the provision of DCV control.”

Elta Group’s Product Marketing Manager, Nygel Humphrey added: “Also important in the schedule was the ability of the ventilation system to provide speed control and fault monitoring for the customer’s Building Management System. It was clear that the DCV enabled Quietflow range was the optimum solution”.

The Quietflow SQS DCV is a finalist in the ‘Air Movement Product of the Year’ category, with the winners to be announced on 25 April at the awards ceremony at the Grosvenor House Hotel, London.

Available in eight standard sizes from 100mm to 710mm, the Quietflow SQS DCV features the BAT (Best Available Technology) Vpro backward curved impeller with three dimensional profiled blades. The impeller is powered by the Ziehl-Abegg EC external rotor motor, offering high energy efficiency and excellent reliability.

The Quietflow SQS DCV is part of the demand controlled ventilation range which, when coupled with sensors, further improves already impressive energy savings by matching the speed of the fan to the occupancy levels of an environment. Energy Consumption and Performance testing on a 250mm unit demonstrated that a reduction in operating costs of 60 percent can be achieved by the SQS DCV, compared to the standard SQS fan. This is achieved through the improved energy efficiency of the DCV version which can remove the same amount of air from an occupied space whilst operating at a reduced speed. This cost saving can be increased to 92 percent if a sensor is employed to vary the flow rate based on the CO2 levels detected. As an acoustically treated single in-line fan it provides excellent sound characteristics which makes it suited to applications requiring location close to building occupants, and, as a compact unit, it is ideal for overcoming space restrictions in buildings with low ceiling voids.

Jenna Chambers, Strategic Marketing Manager at the Elta Group, comments – “Given the increase in the number of entries to this year’s awards we are delighted to make it through to the shortlist. The new blade geometry offers real benefits in terms of low noise emission, reliability and improved efficiency. There is a very definite focus on how energy savings can be made in building services technology so we are hoping that the results of the product comparison trials will impress the judges and stand us in good stead for the awards in April.”

The Kingswinford-based manufacturer supplied a total of ten units: three Jetflow SJs; two Quietflow SQTs and five Multiflow SMBs, for use within the ventilation system of the new-build project, a £4million, state-of-the-art Institute of Construction & Engineering (ICE), undertaken with the support of the Scottish Funding Council. The teaching facility, located at the College’s main campus in Paisley, offers a range of courses to students.

Marking a growth in the area of renewables, Reid Kerr is at the forefront of this training provision in Scotland and the College now offers an increased programme that includes ‘Construction & Built Environment’, ‘Engineering’, ‘Energy’ and ‘Utilities’. It boasts a modern environment and firstclass learning facilities and is one of the fastest-growing, further education institutions in Scotland. Specialist conditions in the ICE provide a realistic working environment to enhance the learning experience where students employ their practical skills to complement their theoretical knowledge.

Various working fans were left exposed and these are now in use for demonstration purposes on courses such as HNC Construction Management, Intermediate 2 Renewable Energy and Intermediate 2 Electrical Installation.

The range of Jetflow SJ, all metal, in-line centrifugal fans, is one of the most extensive on the market. It is designed to provide high-performance in medium-pressure extract or supply systems and is suited to residential, commercial and industrial applications. Quietflow SQT is the Elta range of acoustically treated, in-line centrifugal twin fans, manufactured in galvanised steel with a natural finish. Designed for internal mounting to overcome space restrictions in buildings with low ceiling voids, the compact units emit exceptionally low sound characteristics and so can be sited in close proximity to building occupants. Multiflow SMB is the range of square-cased, mixed-flow fans from Elta with a unique, adjustable-pitch impeller. It is suitable for extract or supply installations, mainly within ductwork for a range of industrial and commercial applications.

The fans were installed by Dalziel Services of Motherwell in Ayrshire, mechanical and electrical contractors who have recently completed projects for several clients from the education sector, undertaking new build and school refurbishment, extensions, college and university works and remedial works/testing. The units were provided through Elta’s distributor Keets, the ventilation, cooling and bathroom suppliers from Glasgow – and the whole project was completed in August 2011.

Elta is part of the £85 million Elta Group, a family of businesses with operations in six countries on four continents which, together with a network of international distributors, provides quality fans and related air movement equipment to customers worldwide.

Elta has extensive experience of supplying heating and ventilating solutions for a diverse range of applications, including schools and colleges which have proved a particular growth area for the business in recent months.

The Springwell Community School is a mixed comprehensive serving almost 1,000 students in the former mining area of North East Derbyshire.

In recent years the original 1960’s buildings have been extended significantly with a number of new facilities added including a Performing Arts Centre and a Sports Complex, with the school having now achieved a “Specialist College for the Arts” status. Local main contractor Bowmer & Kirkland are currently involved in a multimillion pound construction project to create a brand new series of five buildings, with a combined footprint of 6,150 square metres, which will ensure the school will be a hub for education in the Staveley and Brimington Community.

A critical part of any school is the means through which the optimum environmental conditions are achieved and maintained, with the sound performance of the heating and ventilation system a particular consideration in a learning environment.

A series of Quietflow SQS single fans and Quietflow SQT twin fans were specified by electrical and mechanical sub-contractor Derry Building Services, manufactured by Elta and supplied through Leicester based MasterAir, one of the companies within Elta’s comprehensive network of distributors. Manufactured from thick galvanised steel with the centrifugal impellers driven by motors mounted on anti-vibration mounts, the Quietflow fans, as the name suggests, are designed to combine optimum performance with minimum noise. The fans are tested to the latest British Standards for airside and noise performance at Elta’s own test facilities, ensuring current and reliable data.

Acute hospitals provide a diverse range of specialist care and treatment for patients. Typically, services include: consultation with specialist clinicians; emergency treatment; routine, complex and life saving surgery; specialist diagnostic procedures; observation and short-term care of patients with worrying symptoms. The first phase of the Forth Valley Royal Hospital is now complete and the hospital opened its doors to patients in August 2010.

The new-build, £300m facility will be one of the most modern and well equipped hospitals in Europe. Equipment supplied by Elta was mostly from the SELECT range, one of the widest available directly from stock. It included two Powerduct SPD fans, a Multiflow SMB, six SmokeVent LCS fans, a Quietflow Twin, two JetFlow fans, along with twenty special centrifugal fans sourced from Fans & Spares Limited Glasgow.

The Powerduct SPD range of robust, duct-mounted, square-cased, in-line centrifugal fans is designed to deliver high performance with low noise characteristics. Multiflow SMB is Elta’s range of square-cased, mixed-flow fans with adjustable-pitch, mixed-flow impellers, for use within ductwork. SmokeVent is for general ventilation plus emergency smoke extract and Quietflow SQT is the acoustically treated, in-line, centrifugal twin-fan range, intended for internal mounting in buildings with low ceiling voids, where fans are close to building occupants. Jetflow is one of the most extensive ranges of all metal in-line centrifugal fans and, again, provides high performance in either extract or supply applications.

As Elta only make metal fans, Elta’s Stuart Johnstone approached Alan Burns at Fans & Spares Limited, another national ventilation distributor and part of the Systemair group since 2004 with a request for an unusual collaboration. The Glasgow office, headed by Mr. Adrian Park, was more than happy to supply the twenty, 315mm plastic, in-line, duct fans that were needed to complete the order for the Forth Valley hospital. Mr. David Renwick of the project’s services providers, Crown House Technologies, one of the UK’s principal building services providers and a leading prefabricator of modular services, said: ‘We have a very good relationship with Elta. As well as supplying their equipment and sourcing the twenty, plastic, in-line, duct fans for the project, they also agreed to Fans & Spares Limited being the single point of contact close to site in Glasgow, liaising with them closely in order to simplify the purchasing process for us. Both suppliers also responded very quickly whenever site visits were required to assist us during installation.’

The NHS Forth Valley area has a population of nearly 280,000 and covers a geographic area from Killin and Tyndrum in the North and Strathblane and Bo’ness in the South, incorporating a mixture of rural and urban areas. Forth Valley Royal will include a mental health facility and a women & children’s unit. It will have 860 inpatient and day beds, sixteen operating theatres, twenty-five wards and 4,000 rooms. It will cover an area the size of nine football pitches and will eventually feature the UK’s first robotic supply and delivery system, Scotland’s first fully robotic pharmacy system and high-tech kitchens. The new hospital will replace Falkirk, and, Stirling Infirmaries and services will transfer across in a number of stages over the next year starting with services from Falkirk and District Royal in August 2010. The Minor Injuries Unit in Falkirk and the A&E Department in Stirling will continue to operate as normal until July 2011 when these services will move across as part of the final phase.

The new hospital is set in stunning surroundings in a largely parkland setting with mature woodland, ponds, landscaped courtyards and a visitor garden. It offers spectacular views across the Forth Bridges, the Lomond Hills and the Ochils.

The Pearl-Qatar is a multibillion dollar, man-made island developed in an exclusive environment of reclaimed land, covering 400 hectares with 40 kilometers of coastline and 20 kilometers of pristine beaches. It is set to become the ‘Riviera Arabia’ by offering a lifestyle reminiscent of France and Italy in the heart of the Arabian Gulf.

Elta Ltd and sister company Fastlane Ventilation Equipment Ltd supplied the fans to contractor Power Line Engineering, Qatar, through regional distributor METCO, for use in various public areas. These included several food and beverage outlets in the central plaza and the major north-south boulevard, as well as the smoke management system for the mall area, where a network of smoke extract fans is integrated into an addressed fire alarm system. Both companies worked together to fulfill the order which included HIT, Compact SCP, Powerduct SPD, Multiflow SMB, Skyflow SSMF, Heritage SCHT along with long-cased (LC) and short-cased (SC) Axial fans for the retail and recreational areas, with Fastlane supplying BSB SISW centrifugal, belt-driven units for kitchen extract applications.

Elta’s Compact SCP is a durable and weatherproof, slim-profile, plate-mounted axial fan with efficient, lightweight motors offering all round performance and simple speed control.

Powerduct SPD is a range of robust, duct-mounted, square-cased, in-line centrifugal fans offering performance with low noise and suitable for a wide variety of applications.

Multiflow SMB is a range of square-cased, mixed-flow fans with adjustable-pitch, mixed-flow impeller, suited for extract or supply within ductwork.

Skyflow SSMF horizontal-discharge, mixed-flow, roof extract units offer a low-profile design, are UVstabilised, durable and long lasting.

Heritage SCHT range of roof-mounted centrifugal fans are designed to handle clean, grease laden or contaminated air and providing easy access for cleaning.

The SmokeVent SLCS range has been specifically developed for emergency extract systems to operate as part of the main extract system or as a dedicated, emergency clearance system to remove hazardous fire, smoke or fume conditions.

The Pearl is planned to be a unique living and cultural experience that integrates the best of the country’s past and present and is Qatar’s first luxury residential urban development venture that offers international investors freehold title ownership. The project developer is United Development Company (UDC), Qatar’s largest private sector shareholding company whose founders are among Qatar’s most successful investors and developers.

Located approximately 20 kilometers north of the downtown central business district of Doha and directly north of West Bay just off the shore of the Arabian Peninsula, it is on the site of a former pearl diving site. When fully developed, the island will house approximately 18,000 beachfront villas, elegant town homes, luxury apartments and exclusive penthouses, which will be home to up to approximately 41,000 residents. Current plans are for at least three 5-star hotels and there will be three marinas with mooring for approximately 1,000 boats. Extensive private and public moorage is planned and the island will have canals, lakes and interior navigable coves. The island will host a yacht club of world-class standing to cater to the international, regional and local yachting community. Approximately 2,000,000m2 of retail, leisure and restaurant space will again be targeted at the top end of the market. Locations have been identified for at least two schools and there will be several kindergarten and day care centers. The island will also have several public parks and accessible open spaces.

Twin-fan units are used in various applications that require guaranteed continual ventilation. The two fans are mounted within the same unit, with only one fan operational at any time. The second fan acts as a backup and only becomes operational if the primary fan fails. To ensure longevity, there is a duty share schedule programmed for change every six hours, whereby the operational fan becomes the backup fan and vice versa. Typical applications include hospitals, public buildings, office buildings, toilets or other areas where volatile organic compounds (VOC’s) are present and necessitate extraction on public health grounds.

‘Quietflow’ is the range of acoustically treated, compact units from Elta designed to overcome space restrictions in buildings with low ceiling voids and to provide exceptionally quiet performance when installation in close proximity to the occupants is unavoidable. ‘QuietflowDCV’ is the manufacturer’s affordable solution for ‘demand control ventilation’, providing optimum air quality combined with low energy usage. It does this whilst making significant energy savings through the use of variable speed solutions to ensure the ventilation rate always matches the occupancy rate in order to maximise indoor air quality cost effectively.

QuietflowDCV units are robust, lightweight with low-profile, galvanized steel casing and flame-retardant, Class O-rated acoustic lining – so breakout noise levels are significantly lowered. The high-efficiency, backward-curved, centrifugal impellers are directly driven by an external rotor motor, mounted inside the fan casing and designed to provide reliable, continuous air extraction with a smooth airflow. The impeller axis runs horizontally across the unit, which minimizes the overall height of the unit for ease of fitting in roof spaces.

The three main elements comprise the sensors, zone controller and room controller. The sensors continuously measure and monitor ambient conditions in the conditioned space and provide real time feed back to the zone controller which adjusts the fan speed, modulating the ventilation rate to match the specific use and occupancy of the building. The room controller provides a clear overview of the settings and status, with simple intuitive operation and unobtrusive aesthetic design. All QuietflowDCV units are suitable for 220-240V operation and all the AC-motor specified units operate on 50Hz whilst all EC-motor specified units can operate on 50Hz or 60Hz. They are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance). All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2000.

The school, St. Andrews High School, is a Roman Catholic, mixed, comprehensive school in Overton Road, Kirkcaldy, serving the eastern side of Fife.

Fifteen fans were supplied to mechanical and electrical subcontractors Livingston Mechanical Services Limited, through Elta distributor Lindab Glasgow. The order comprised five Quietflow Single, four Compact Plate fans, three SJ Jetflow, two STBD Twinflow and one Quietflow Twin along with all necessary speed controllers and invertors for use in the school’s new heating, ventilating (both smoke and natural ventilation) and air conditioning systems.

The project is the current phase of the local council’s alteration and extension programme – started as far back as 1999 – to upgrade the school and remove all the hutted accommodation from the school estate. It consists of alterations to the existing buildings, the forming of a link connection and the construction of a new, three-storey teaching block extension for Art & Design, Music, Computing, Business Education, Religious Education and Home Economics. It also includes new ancillary accommodation to address schooling needs, with energy efficiency and sustainability very much at the heart of the construction programme.

Stuart Johnstone, Key Account Manager for Elta in Scotland and responsible for the St Andrews project, comments ” “The education sector has become increasingly important to us as a business. It is a sector in which an environmentally aware approach to building is very much to the fore and this fits very well with our own philosophy of seeking to maximise the energy efficiency of our fans to contribute to that whole process of reducing the carbon footprint of school buildings. Maintaining a good balance of heating and ventilation is seen as particularly important in schools since stale, stuffy air and increased CO2 levels (as well as noise from equipment where attention has not been given to noise reduction) can have a significant impact on concentration levels, directly impacting on the ability to learn.”

Main contractor on the project is HBS Construction Glasgow, which has a strong reputation in the building sector ranging from the provision of primary and secondary level classrooms blocks, to extensive teaching and research facilities. Consulting Engineers are Grontmij, one of Europe’s largest multidisciplinary firms with clients in the private and public sectors.

A new games hall was opened in 2000 as the first stage of the programme, and a new building for Social Subjects and Guidance opened in 2004. The most recently completed extension at the rear of the school was opened in December 2008. In July 2009, work commenced on the refurbishment of two Craft and Design classrooms. In partnership with a local company, the school will also be refurbishing a classroom as a ‘Classroom for the Future’, a multi-purpose teaching area. Other projects currently ongoing within the education capital programme, include rainwater harvesting, increased building insulation/air tightness, natural ventilation strategies with window actuators – and a sedum roof.

‘The Orchards Federation’ at Cherry Tree, a new 350 pupil integrated special school/primary school in Farnworth, Bolton brings together the foundation stage, nursery and reception pupils from Cherry Tree Primary School, Green Fold Special School and St Germain Nursery in a single, ‘green’ building to share knowledge and best practice for the benefit of all their children.

Main contractors, Frasc Mechanical Services Limited of Walkden in Manchester, fitted each of thirteen, first-floor classrooms with an Elta Revolution SLC315 ” The robust, durable axial fans are fitted with adjustable pitch impellers, factory-set to maximise performance. They also set Elta’s 149-EVFD/18-1 inverter controllers in the ceiling space, complete with potentiometer, enabling staff to have full manual control of the heating and ventilating set-up. On the ground floor, classrooms were fitted with bespoke low profile Heat Recovery Units designed by Fastlane Ventilation Equipment Ltd, manufacturers of air handling and heat recovery units and part of the Elta Group.

The school’s BMS (Building Management System) is programmed to start these various elements of the system on a timing device. In hot weather the Heat Recovery Units are switched to bypass mode whilst the fans on the first floor are set to run backwards (“reverse purging”), to supply the classrooms with cool fresh air in time for the morning start ” a significant contributor to improving the children’s energy and concentration levels, therefore creating an environment much more conducive to learning.

‘The Orchards Federation’ site also incorporates a children’s centre, public library and the youth centre from Wildman Lane. A large format public display screen in the school foyer shows the current power production, total power to date, CO2 saved to date, cost savings to date and other useful information. This plays a valuable role in the children’s education in sustainability, offering a very real, tangible and powerful way of demonstrating a green approach at work.

It is against this background that Elta has developed its approach to Demand Control Ventilation (DCV). DCV is based on the simple concept that an empty room does not have the same ventilation needs as it does when occupied. Building ventilation systems often operate at constant or pre-determined rates (which are often based on maximum expectations) regardless of actual room occupancy. In using the appropriate sensor technology which already exists, DCV supply can be brought in line with demand ” and buildings can be made as energy-efficient as possible.
