Compare transformers and save money!

Electricity prices remain high and there is still no immediate prospect of stability in the energy market. Economical use of electricity and other forms of energy is, therefore, more crucial than ever. One way to achieve this is through the use of equipment with low energy losses: like the exceptionally energy-efficient EREA transformers in our Blue e3 range. These models reduce zero no-load losses and copper losses to an absolute minimum.

Low Total Cost of Ownership
But doesn't that make them more expensive? It is true that the initial purchase cost is a little higher. However the Total Cost of Ownership (TCO) is many times lower than with a cheaper model. In other words you will quickly recoup the additional cost.

Compare, replace, save!

How quickly? You can work that out using our calculator. This allows you to compare an energy-efficient transformer from EREA's blue e3 Range with a transformer from a different manufacturer, or an older and less energy-efficient EREA transformer, so you can quickly and easily see how quickly you can earn back the additional cost of purchase.
