Elta Fans and Ziehl-Abegg join forces

Elta Fans has announced a strategic alliance with Ziehl-Abegg to use the company’s motors and impellers as part of Elta’s commitment to meet new European energy and climate change legislation.

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 specify minimum ventilation rates and Specific Fan Powers, while the ErP Directive focuses on improving the energy efficiency of 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 Fans has already been working towards meeting the requirements.

The first tier of the ErP fan efficiency legislation becomes mandatory on 1 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.

Elta Group Vice-Chairman David Ball 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 Fans 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, Elta Group Technical Manager Alan Macklin says: “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 90 GW are installed in industry applications and that fans are responsible for 22 per cent of industrial motor energy consumption, it is easy to see why it is a fan manufacturers’ responsibility to also address energy and climate change.”

Ziehl-Abegg UK Managing Director Les Fish comments: “The appointment by Elta Fans 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 Fans - a relationship which goes back many years.

“The inclusion of ‘Premium Quality’ Ziehl-Abegg components within multiple Elta Fans product ranges benefits Ziehl-Abegg and Elta Fans, but perhaps more importantly, Elta Fans 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.


Elta Fans launches first wave of products featuring Ziehl technology

Elta Fans has announced the first in a series of phased launches of new products which will be powered by motors and impellers from Ziehl-Abegg, including the first ever fan in the HVAC market sector to feature the Ziehl FE2owlet impeller.

The new alliance between Elta and Ziehl-Abegg was a significant move made to ensure that Elta Fans’ 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 1 January 2013 with more onerous requirements to follow in January 2015, but Elta has taken a pre-emptive stance which will ensure that its 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 Künzelsau-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 an owl’s flight characteristics and combining it with the company’s extensive aero-acoustics knowledge, Ziehl has produced a completely new blade geometry that 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 an owl’s, which serves to muffle the sound of the owl’s wing beats.

Improved efficiency and performance is achieved through winglets on each blade, which are 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 Ziehl Vpro backward curved impeller with three-dimensional profiled blade and optimised blade geometry, providing high efficiency and low noise levels.

A number of re-engineered Elta 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.

This is a first phase of new Elta products featuring Ziehl-Abegg technology, with further phases to be introduced in 2012.
