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.”

Needing to follow the customer and end-user’s pre-defined specification, in addition to a small installation footprint, our engineers built the four bespoke fans at our Fareham-based factory. When building the 1,120mm diameter, stainless-steel long cased axial units, we knew durability was a top priority. We made sure they could withstand the harsh offshore salt-laden environment by using marine-grade aluminium impellers, stainless-steel 316L casings, terminal boxes and ancillaries.

Along with being durable, a key requirement was making sure the fans were explosion-proof and complied with the customer’s design requirements, in addition to offshore and Brazilian safety regulations. As such, the fans were built with C5M-painted Zone 1 ATEX motors, BFOU cabling, and stainless-steel glands. To comply with the Brazilian standard NR-37, motor cowls, access doors, and internal terminal boxes were painted to colour RAL 2008.

For the end-user’s monitoring requirements, the fan models came equipped with Shock Pulse Monitoring (SPM) sensors and a cable transit system to wire the coaxial cable to an externally fan mounted terminal box. Accounting for vibration during installation, the fan mounting plate was paired with anti-vibration mounts.

Leading on the project, Lewis Brand, Technical & Project Sales Engineer at Elta, said:

“Working on applied technology projects means working through customer specifications to ensure we’re designing the best fan for their application, and working with customers throughout a project is something we pride ourselves on at Elta. This project really showcases our engineering capability; four unique fans that we have manufactured to the highest quality and will stand the test of time.”

A Trumpf TruPunch 2020 punching machine marks the newest addition to Elta’s already extensive manufacturing hardware and software, providing greater productivity and flexibility in the manufacture of fans and ancillary equipment employed in a wide range of building services applications.

The TruPunch offers speeds of up to 2,200 strokes per minute when marking, 900 strokes per minute while punching and rotates at three revolutions per second, whatever the tool being used. With all 19 tool stations fully rotational to ensure swift and easy changing of tools to meet different punching requirements, it also reduces the handling of parts by consolidating different operations in a single machine.

Paul Greenwood, Sheet Metal Foreman at Elta’s Fareham site, said – “As with most fabrication, a lot of the processes are repetitive so the capacity for this machine to be accurate and repeat the marking and punching so precisely and so quickly has been a real boost to our manufacturing capabilities. It is being used for fabricating a number of fan housings, including the Revolution Long and Short Case Axials, the Contra-Rotating Axials, and the Multiflow Mixed Flow Fan ranges. We are also seeing the benefits of it in the bespoke manufacturing for which the Applied Technology division here at Fareham is particularly known.”

Another feature of the TruPunch is the integrated loader/unloader facility which automates the process and allows the machine to run throughout the night if required.
