Fläkt Woods has introduced three new high efficiency products to its offering.
The first is a new axial fan in the form of the new JMv range. The fan is said to save end users up to 24 per cent on running costs compared to other products available on the market, and is a pioneering, highly efficient solution for the catering and hospitality sector in particular. With versatility being integral to Fläkt Woods’ design, the JMv can also be used for general ventilation and smoke extract applications to improve indoor climate and preserve life.
Borne from a breadth of research and innovation, JMv utilises Fläkt Woods’ Vortex Creation Control technology, which features a CFD optimised aerodynamic impeller design. Integral to the design are vortex generators on the trailing edge of the impeller blades, which intelligently manage airflow and reduce turbulence to deliver optimum aerodynamic performance.
The unique design means that JMv can deliver enhanced aerodynamic performance, whilst significantly reducing running costs and carbon dioxide emissions, which makes a positive contribution to decreasing the impact of climate change. The fan design also features two-stage guide vanes that boost efficiency further, whilst also providing support for the motor and reducing unnecessary weight.
Andy Cardy, operational marketing manager for Fläkt Wood’s fans division, explains: “JMv is actually our first ‘all new’ axial flow fan product for 22 years, so this is an exciting time in our company history. JMv is a huge step forward in fan technology that will allow us to build on the existing JM fans’ success that has, for many years, been a market leading product.”
“JMv also addresses key needs of modern installers, who are faced with a rapidly changing legislative environment, the impact of rising energy bills and increasingly stringent building regulations.”
“This new range is already ErP 2015 compliant, and in many cases, far exceeds current efficiency targets – so customers can rest assured that any Fläkt Woods product will meet future legislation requirements for years to come.
• Adding to its ventilation offering, Fläkt Woods has launched eCO PREMIUM, a new energy recovery unit that incorporates the latest air movement technology and intuitive controllability.
eCO PREMIUM has been developed to assist schools meet increasingly stringent government guidelines, whilst cutting costs too. In fact, the unit is capable of recovering 85 per cent of the thermal energy, making it a highly efficient solution for schools.
The heat, or energy recovery unit (ERU), also offers what is described as 'an unprecedented level' of control and intelligence, for example, when specified with sensors, eCO PREMIUM can automatically adjust to changing demands within a room.
A presence detector will switch the system on when the room is occupied and subsequently off again when it’s empty, and impressively, an internal CO2 sensor can even adjust the air supply proportionally to the number of people in the room.
The ERU is also available in different air flow capacities, from 0.2–0.9 m³/s, and is remarkably quiet at only 20dBa – offering wider flexibility when specifying the right sized product and choosing the installation location.
David Black at Fläkt Woods explains; “eCO PREMIUM offers great energy saving potential for the education sector, and a lucrative opportunity for installers. By using waste heat from the outgoing air, energy bills can be greatly reduced and can achieve substantial carbon reductions, especially for premises with multiple buildings.”
Crucially, eCO PREMIUM is the ideal solution for the education sector in particular, where the pressure on ensuring student and teaching staff wellbeing has heightened.
• The company's all in one solution for fire safety in residential buildings comes in the form of the single-shaft system designed for buildings between three and 20 storeys. Commonly used as a smoke control measure for high-rise buildings, such as hotels, offices and apartment blocks, mechanical smoke shafts are simple ventilation systems designed to extract any smoke leaking into a communal areas and entrances, protecting the escape stairs. 
Crucial not only for the safety of building occupants, a ventilation system is also essential for the welfare of the fire and rescue services entering the premises in the event of a fire.
Fläkt Woods Smoke Shaft Vent incorporates high efficiency extract fans, mounted on the roof and connected to the ducting to extract smoke –making it easier and safer for occupants to exit the building, and in turn, safer for the fire service to enter. Importantly, with lower levels of smoke present at the time of evacuation, occupants are more likely leave the building in calmer, orderly manner, without fear of smoke inhalation or poor visibility.
Ross Barritt, operational marketing manager for Fläkt Woods Fire Safety Division explains: “Our tailor-made, prefabricated solutions allow for minimal plant lifts to the building’s roof, reduced wiring on site and coordination from separate suppliers of fans, controls, ductwork and dampers. All of the custom designed systems are configured using an easy-selection tool, making our expertise accessible to specifiers, building owners and installers alike.”
“Importantly, our mechanical Smoke Shaft Vent systems not only provide a fire engineered solution using best practice from the latest UK Fire Safety Standards, but they also utilise extract fans selected to meet ErP criteria, ensuring energy efficient operations.”
