Kiepe Electric is specialized in modernization and refurbishment of existing vehicles by implementing new traction electronic, on-board power system or electrical equipment. Our services range from simple cable refurbishment through partial equipment to complete project management.

Following the tight financial pressure of many transport companies, we developed different modernization concepts in cooperation with our customers. The refurbishment of existing vehicles extends the lifetime and enhances the travelling comfort und thus the attractiveness of the existing vehicles. The maintenance costs of the vehicles can be reduced considerably (retardation of the LCC) by modern traction and on-board power system supply. Also the energy consumption of the vehicles can be reduced significantly by implementing efficient traction technology and static converters.

This reduced not only the carbon dioxide equivalent but also the energy costs.

Due to low energy costs, modern traction equipment depreciates already after about four to eight years, depending on the operation mode and infrastructure. This has already been verified by Kiepe Electric in several projects already put into practise.

Let us convince you by setting up an economic efficiency calculation for your fleet. Please contact us!
