At The Heating & Ventilating Exhibition at the NEC, Birmingham (24-26 Feb, 2009) – the most comprehensive exhibition of hvac equipment ever staged in the UK – Elta are launching their new and innovative Quietflow DCV (Demand Control Ventilation) system.

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.

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.
