buses and trolleybuses

ENIKA has been developing electric systems for wheeled vehicles for over 30 years. Starting with trolleybuses and hybrid buses, the company gradually expanded its portfolio to include electric buses and now also provides solutions for hydrogen buses.

In the trolleybus sector, ENIKA is a pioneer of modern asynchronous drives in Poland – the first such solution installed in a trolleybus was launched in 2005. Currently, the company offers a proven conventional solution with double insulation and forced air cooling, designed for both classic trolleybuses and vehicles equipped with traction batteries.

A solution with a liquid-cooled inverter, supplied by parent company MEDHA, weighing approximately 30 kg, is also available for electric buses. This inverter is complemented by an air-cooled roof-mounted power distribution unit. A modified configuration of this unit is also available for hydrogen buses.
