Visionaries

We recognise the importance of the environment in which we live.

Responsible

to the environment which is home to all of us.

An active participant

in improving the environment in which we live.

A supplier

of clean technology.


Our offer

  • Supply of clean drive technology for existing buses
  • Solution to reduce gas and noise emissions
  • Universal modular product
  • Bus autonomy up to 250km, depending on battery sizes
  • Charging via three-phase electric socket – charger is already in the bus

What did we do?

  • We developed a product with our own knowledge which prevents the exhaust emissions of buses from being released into the environment
  • Solution for the existing fleet
  • Reduced the running costs of use and thus the cost of ownership
  • Reduced noise in the environment
  • Environmentally friendly product at the highest technological level

Why we did this?

  • The growing need for clean buses with zero emission of exhaust gases
  • High cost of purchasing new electric buses
  • We make buses which are still operational and are far from the end of their lifespan environmentally friendly

How we did this?

The vision of a clean environment brought about an idea to produce a universal modular product, which allows a quick and simple change of internal combustion engine with an electric drive.






We installed the product in a 20-year-old bus and demonstrated that the systemworks regardless of the age of the bus.



Refurbish process


We removed the engine and the gearbox

We repaired damaged parts

We embedded the SIEMENS central motor

We embedded auxiliary devices
We embedded battery cells


The result is a refurbished bus
