Viledon Presents New Energy Efficiency Classification

The smart way to reduce energy costs

In addition to its environmentally orientated focus, sustainable business development also possesses an important economic component: cost reduction. High energy prices, increasing competitive pressure and, not least, the current tough financial situation across world markets, are all forcing businesses to reduce their energy use more consistently. Also, the overall need to reduce CO2 emissions remains an important consideration. In this context, the demand for the use of energy-efficient filters is rightly a key point of focus.

Pressure losses are energy losses

A look at the energy consumption of ventilation systems revealed significant potential for savings. Within office buildings, the proportion of energy use of filters represents around 40% of total energy consumption. In clean rooms, for example in hospitals, this proportion rises as high as 80%. Among other elements, the things responsible for this level of energy use include pressure drop, which lead to higher energy intake by frequency controlled fans. Pressure losses are largely caused by the performance of the air filters. By using energy-optimised filters, such as Viledon, it is possible to reduce pressure drops significantly and thus ultimately to save valuable energy and associated costs.

Cost control using energy efficiency classification

Previously, it was not possible for consumers to distinguish between efficient and inefficient filter solutions. The currently applicable testing and classification standards (e.g. EN 779) are no help in this regard, since they only relate to the particulate filtration effi ciency of filters, not to their operating costs. With the new Viledon® energy efficiency classification system, filters can be assessed and compared on the basis of energy consumption costs for the first time. Using a system of five energy efficiency categories, filters can be accurately assessed in terms of operating costs. Classes 1 and 2 indicate particularly energy-saving performance, with Class 5 indicating especially poor energy performance.
