New solutions to existing plants


Not every country’s economic situation encourages businessmen to make heavy investment in replacing their asphalt plants. Nowadays, with plant revision, it is possible to make an existing plant competitive even when compared to the most modern sites. Therefore, with limited investment, the company can be competitive and maintain, or even increase, their share of the market.

Upgrading = immediate economic returns.



Retrofitting in the world of asphalt plants is a self-explanatory word which covers all the operations of renewing dated equipment, prolonging its useful working life and increasing plant performance. Retrofitting consists of adding new solutions to existing plants, replacing obsolete or dated technologies with new solutions and also giving new life to parts which need replacement while still reutilizing the plant parts which still have a valid life span.
