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.”

Elta’s Design PREMA range boasts the smallest and lightest energy recovery ventilation units on the market, which also offer peaceful performance for a comfortable indoor environment. The units work by maintaining good indoor air quality and comfortable temperature levels by efficiently transferring thermal energy from the stale air to the incoming fresh air.

The units are available in four sizes to provide an airflow ranging from 0.006 to 0.936m³/s, and are suitable for a wide range of markets and applications, from schools and offices, to restaurants, hotels, and leisure centres.

Enhanced Filtration

The established product range now boasts improved indoor air quality by including a fine particulate filter on intake as standard. ISO ePM₁ 55% (F7) supply fine particulate filters are fitted in the units to remove pollutants and provide pure, clean, fresh air that encourages concentration and productivity.

Heat/Coolth* Recovery

In ‘heat recovery’ mode, the unit utilises the heat in the extracted air to warm the incoming air to increase the incoming external supply air to the desired temperature for the space or room. In ‘coolth recovery’ mode, the unit utilises the coolth in the extracted air to reduce the incoming air temperature via the heat/coolth exchanger block when desirable.

Dual Condensate Tray

A crucial addition to the new product range is the dual condensate tray meaning condensate can be dealt with on both sides of the high efficiency heat/coolth exchanger block via two separate drain points. This twin condensate drainage arrangement prevents unit internal air leakage and the possible undesirable accumulation of condensate on the fan chamber which could lead to poor quality air entering the occupied space.

Controls Capability

The PREMA and PREMA+ units can be easily paired with the innovative Kinairtico0 and Kinairtico Mini indoor air quality and energy recovery management devices. Offering easy and adjustable installation, set-up and BMS monitoring, along with superior controllability of the ventilation system, customers can select the best control option for the applicated via a tiered structure.

Thermal Treatment

The PREMA unit range now includes the PREMA+ that comes with new product features focused on comfort, ventilation and automation. The key addition to the PREMA+ energy recovery unit is its thermal treatment capabilities, allowing it to top-up the heating demand of the ventilation system in colder winter months to bring temperature to a comfortable level for occupants. The thermal treatment components available with the PREMA+ units are an electric heater of hot water coil.

Ana Cross, Associate Product Manager Air Handling Systems (UK) at Elta Group explains: “PREMA is a popular product range for us but in light of changes to air quality standards and strict building regulations, we wanted to improve our offering to be compliant while providing end-users with more benefits in terms of efficiency and control. Our proudest additions to the range are the improved automation packages for both PREMA and PREMA+ which allow clean and comfortable ventilation to be delivered efficiently, whenever it is required.”

The ErP Directive came into force on 1 January, 2013, replacing the Eco-Design Directive EuP (Energy-using Products). The Directive is being adopted as a series of ‘lots’, with the lot to address centrifugal fans currently out for comment and not yet adopted. However, in line with Elta’s commitment to employing the Best Available Technology and constantly evolving their range of products, the Viper SCC has been designed with the impending legislation very much in mind.

The Viper SCC range comprises eight standard sizes from 250 to 630mm, all of which carry a 12 month warranty. The range continues the recent developments of fans designed by Elta that incorporate motors and centrifugal Vpro impellers by Ziehl-Abegg, one of the world’s most respected electric motor and fan manufacturers. The highly efficient, lightweight external rotor motors (available in EC or AC options as standard) are designed to provide high-performance characteristics.

AC motors produce air volume rates of up to 1.16 m3/s with static pressure of up to 520 Pa – and EC motors produce up to 1.73 m3/s with static pressure of up to 850 Pa. With sealed for life bearings, the motors are insulated to Class F and weatherproofed (sizes 250-350mm to IP44 and sizes 400-630mm to IP54.) All have integral thermal overload protection and are suitable for use with a speed controller. Driven directly by the motor to provide a smooth airflow through the unit, the high efficiency, low tonal noise, backward curved, centrifugal impellers are dynamically balanced to grade 6.3. They are suitable for use in operating temperatures up to +60°C.

To provide a long lasting and robust construction, the Viper units have all metal casings and guards built from mild steel, which are treated to ensure full corrosion protection. Fan casings have a powder coated, polyester, epoxy paint finish in pastel beige (RAL 7032) and the guard in black (RAL 9005). Units are designed and manufactured in accordance with procedures as defined in BS EN ISO 9001: 2008 and tested to ISO 5801: 2007 (airside performance) and BS 848 Part 2: 1985 (sound performance).

The Viper SCC is one of a number of new products featured in the brand new Elta Select 2013 Product Guide. At 528 pages, this comprehensive guide to Elta’s fans, ventilation products and accessories, offers all the information required to specify with confidence products that comply with the latest developments in legislation.

The guide includes a wealth of information, including how to select a fan; the different installation categories; details of the new legislation; and, importantly, an explanation of the new product labels which are required under the new legislation to ensure it is easy to identify that products meet the specified criteria.

Elta is part of the £90 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.

The new alliance between Elta and Ziehl-Abegg was a significant move made to ensure that Elta new products comply with the requirements of the new European legislation regarding energy efficiency. The first tier of the Energy related Products (ErP) Directive will implement mandatory fan efficiency legislation from 1st January 2013 with more onerous requirements to follow in January 2015, but Elta has taken a preemptive stance which will ensure their product range is in advance of the legislative deadlines.

The launch of the first Elta products to be powered by Ziehl technology includes the Raptor range. Available as a plate fan, cased axial fan, or plate mounted ATEX fan, the Raptor is the only fan currently available on the HVAC market to feature the Ziehl FE2owlet impeller. The research department at KÌÄå_nzelsau based Ziehl-Abegg drew from nature in developing the all new Owlet, recognising the owl as a bird renowned for its silence in flight.

By borrowing scientific insights into the owl’s flight characteristics and combining it with the company’s extensive aero-acoustics knowledge, Ziehl have produced a completely new blade geometry which excels in terms of low noise emission, reliability and high efficiency. To reduce noise, the blade has been designed with serrations on the trailing edge of the wing, like the owl, which serves to muffle the sound of the owl’s wing beats. Improved efficiency and performance is achieved through winglets on each blade, used on aircraft to smooth airflow near the wing tip to reduce the lift-induced drag caused by wing tip vortices.

The Raptor fan range features an all metal casing, treated to ensure full corrosion protection, with all parts including the guard finished in a powder coated polyester epoxy paint to ensure long lasting and robust performance. The Ziehl-Abegg motors are highly efficient, lightweight external rotor motors with sealed for life, maintenance free ball bearings, allowing the fans to be installed at any angle.

Incorporated into Elta’s products, the Centrifugal Fans include the Vpro backward curved impeller with threedimensional profiled blade and optimised blade geometry providing high efficiency and low noise levels.

A number of re-engineered Elta’s products are to be launched, including the Hideaway, Quietflow, Singleflow, Twinflow, Skyflow and QUBe fans, all of which are powered by Ziehl-Abegg motors and impellers.

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.

In the HVAC sector, implementation of the European Union energy objectives is legislated by the Energy Performance of Buildings Directive (EPBD) and the Energy related Products (ErP) Directive. The EPBD is applicable to fan systems through Parts F and L of the Building Regulations which specifies minimum ventilation rates and Specific Fan Powers, and the ErP Directive focuses on improving energy efficiency of the fans, motors, air handling units and related equipment. The ErP Directive is the most significant legislation the fan manufacturing industry has ever faced.

Recognising the importance of this legislation and the fundamental changes it will mean for fan manufacturers, Elta have already been working towards meeting the requirements. The first tier of the ErP fan efficiency legislation becomes mandatory on 1st January 2013 with more onerous requirements to follow in January 2015, but the majority of the products within the new ranges being introduced by Elta from January 2012 – which feature Ziehl-Abegg motors and impellers – will comply with the requirements.

David Ball, Vice Chairman of Elta Group Ltd, comments – “This new legislation has provided focus for Elta as a business and we will be striving to ensure that our products meet the requirements well in advance of the new legislation being enforced. By combining our own engineering expertise and experience with that of Ziehl-Abegg, we are creating a strong partnership culminating in a range of products powered by Ziehl-Abegg, designed by Elta. This partnership goes much deeper than the legislation, with the owners of Elta working with Ziehl-Abegg previously for more than 25 years with Roof Units Ltd prior to its sale. It is important that our customers can future-proof their HVAC installations now, hence setting up this alliance some time ago, rather than waiting until the legislation is right on top of us in 2012.”

Commenting on the ErP Directive, Alan Macklin, Group Technical Manager at Elta Group, said – “Ways of reducing energy use in buildings has been a focus for some time. This will only accelerate as we look at the forward estimates for population change and electricity consumption: By 2030 cities will be consuming three quarters of the energy we produce and by 2050, three quarters of the world’s population will be living in cities. Given that in the UK alone over 11 million electric motors with a capacity of 90GW are installed in industry applications and that fans are responsible for 22 percent of industrial motor energy consumption, it is easy to see why it is a fan manufacturers’ responsibility to also address energy and climate change.”

Les Fish, Managing Director of Ziehl-Abegg UK, commented; “The appointment by Elta of Ziehl- Abegg as its primary OEM supplier of AC and EC, axial and radial motorised fan impellers has enabled the rekindling of a relationship between Ziehl-Abegg and the Ball family the owners of Elta, a relationship which goes back many years. The inclusion of ‘Premium Quality’ Ziehl-Abegg components within multiple Elta product ranges benefits Ziehl-Abegg and Elta, but perhaps more importantly, Elta customers.”

The first phase of new Elta products featuring the Ziehl-Abegg motors and impellers are to be launched in January, 2012, with a further three phases to be introduced by January 2013.

Eltadrive Inverters are one aspect in the control of ventilation fans. They offer cost savings through the reduction of energy usage at reduced fan speeds and the ability to control the fan via sensors such as humidity, temperature and pressure.

QUBe double skinned centrifugal fan units are highly efficient and resistant systems, with models capable of handling the most arduous and elevated temperatures. Each QUBe unit is user and installer friendly with low noise generation.

The new high pressure PowerPlus range brochure will also be available. The range has been specifically developed to tackle higher pressure requirements with a straightforward, efficient and definitive approach. The totally enclosed air over motors, along with their low profile robust Ushaped mounting brackets, allow for maximum open area, reducing velocities through the fan casing and resulting in increased efficiency and a reduction in noise and vibration levels.

Elta is fully committed to the reduction of carbon footprints in new and existing buildings, by using higher efficiency and lower energy products, components and control systems. Recent and developing legislation highlights the need for faster and high quality product and system development in the important area of energy conservation. Demand Control Ventilation (DCV) is an effective way of applying this philosophy as it allows variable ventilation solutions to be efficiently applied to variable occupancy spaces in buildings.

Reductions in noise ratings, cable sizes and the total amount of energy usage are very important factors, both for customers and for Elta’s product development programmes. Elta’s goal is to provide high quality, energy efficient products with a cost effective ventilation solution.

Elta has one of the most comprehensive and flexible ranges of general purpose fans available, from 100mm to 2m diameter. Within the field of air movement, Elta products have developed around building services applications, air coolers and refrigeration to offshore and marine, industrial processing, power generation, traction and other specialist markets.

Elta is the leader in fans for smoke extract, with a comprehensive range certified to EN12101- 3, car park ventilation, using jet impulse and induction technology, and for use in hazardous areas, under the ATEX standard.

Elta’s product ranges are available worldwide, either through appointed distributors, directly or via companies manufacturing under licence, several of which are also part of the Elta Group.

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.

In the face of sharply increasing fuel costs, the rapidly rising costs of owning and operating H&V equipment and services, added to the new environmental imperative “to be seen to be green”, one of the recurring themes at H&V09 will be low energy, low carbon solutions. Quietflow DCV allows the efficient and effective implementation of variable ventilation solutions to variable occupancy spaces within a single building in order to save energy – and money.

The Elta Group has been fully committed to helping reduce the carbon-footprint of buildings for many years through more efficient components, products and control systems using less energy. But today’s soaring energy costs, along with recent and anticipated future legislation, are hastening the industry’s drive for faster product and system development in the important area of energy conservation.

In the Quietflow DCV system, Elta has combined energy-efficient fan and impeller units with the ability to use Elta’s DCV control methodology. This combination and the use of electronic functionality to integrate complementary modes of operation and efficiency, make the units quieter, more energy-efficient and maximises control efficiency to enhance potential savings in energy costs – moving ventilation ‘through a paradigm shift’ into a whole new era of technology.

The latter cleverly uses different forms of sensor to provide a vast array of different detection modules to detect the level of spatial contaminant (e.g: people, temperature, CO₂, humidity) within the building. The sensors provide an almost infinite amount of variation to the ventilation system so that it matches the level of occupancy within the space. The intelligent system will also interface easily with other enabling systems (infra-red PRI, building automation systems) so that the end-user can be alerted to changes in performance levels, energy levels, maintenance requirements etc.

Efficiency of the fans has been greatly improved. Some models are fitted with a backward-curved impeller to provide around 87% efficiency. Also, a self-extinguishing, acoustic lining provides an enhanced and greatly improved noise-rating when compared to similar models. For cleaning and maintenance, access is much simpler via easy-to-remove top panels and the control systems also incorporates SELV (Safety Extra Low Voltage facility) for the greater protection of users and installers alike.

Generally all Quietflow DCV units have been designed and developed to minimise their height, so that they can fit easily into ceiling spaces and voids. Multiple choice of fan allows for a wide range of airflows to ensure a good choice for the customer. They are ideally suited to either new-build or refurbishment projects where space is at a premium and energy conservation is a priority.

Quietflow DCV units have been fully tested in compliance with ISO 5801:1997 (airside performance) and BS848 Part2: 1985 (sound performance) in order to provide accurate and reliable test data. All Quietflow DCV products (indeed, all Elta products) are designed and manufactured in accordance with BS EN ISO9001: 2000 to strict design and manufacturing standards.

The Quietflow DCV is the first product in the range of in-line box fan units, with the twin fan unit following later in 2009.

The new, full colour Quietflow DCV brochure will be available from Elta at the H&V show or alternatively by calling +44 (0) 1384 275800 or email bs@eltafans.co.uk.
