About
"CO2 equivalent"

Loss generated by thermal heat-up occurs in all electrical components – also in transformers. Although the efficiency of these is up to > 99 % nowadays, the loss at all active transformers in Central and Northern Europe is around 5.7 %. This energy loss must not only be additionally produced, it goes without saying that it also costs natural resources. It is a common fact that electrical energy heats up the ambient air and thus has detrimental consequences for the climate. Energy generation methods involving fossil fuels have a greater impact on the environment. The production of electrical power units, such as solar panels or vehicle batteries uses considerable amounts of energy and around 70 % of the global energy required for this purpose is produced by burning coal.

The CO2 equivalent provides information about the quantity of gas emissions generated during energy production. IWR / 2013 defines that in Switzerland, Northern and Western Europe one kilowatt hour of energy (1 kWh) generates 590 g of carbon dioxide.

Transformers overview

203 design (BDVU)

This extremely efficient Smart-E-Power® transformer has been optimised to generate the lowest levels of load loss. It is characterised by a tremendous overload tolerance of 10 minutes. If you take into account lifecycle costs, the Smart-E-Power® is the best product, there is no doubt about it! Efficiency levels over 99 % are already possible from around 25 kVA. It is also the most silent unit generating the lowest levels of no-load losses of all series.

202 design (BDVA)

This transformer is suitable for a short-term tendency to harmonics and is very efficient. Its sustainable design guarantees customers benefit from appealing lifecycle costs and make a great choice in terms of the CO2 equivalent. Thanks to a special processing method and the use of grain-oriented sheet metal panels, this series is particularly silent.

204 design (BDVK)

This transformer is characterised by its low weight and compact design. Its width, depth or height can be adapted to meet customer demands and suit the corresponding installation space. The use of high-grade materials is reflected in the product quality. The noise generated by the 204 design has been restricted to a minimum, thus making it very versatile.

201 design (BDF)

The standard transformer is particularly suitable whenever its use is not specifically linked to a certain function. For this design we use materials that are common within the industry. It goes without saying that we also focus on quality in this context. The procurement costs of the standard series are the lowest.
