It can be a challenge for asphalt producers to keep up with ever-changing industry codes and standards. Regulations are frequently updated for noise and dust emissions, sampling options, the production of foamed asphalt and the feeding of additives into mix.

Your business has no choice but to meet the revised standards. While buying a brand-new plant would accomplish that, it might not fit in your budget.

A plant retrofit could be the answer. Retrofitting is a much more cost-effective approach, centered on improving an existing plant to meet the same standards as its newer counterparts.

Ammann has a tried-and-test retrofit process. All projects are managed by the Ammann Retrofit Centre in Austria, which relies on proven processes and experienced technicians to troubleshoot any issues and ensure superior results.

A retrofit costs a small fraction as much as a new plant, and is available for asphalt-mixing products made by Ammann and other manufacturers.

What Do You Get With a Retrofit?

Environmental Upgrades

Bitumen Tank

Ammann’s electrically heated E-Bit bitumen tank system provides so much energy savings that the replacement pays for itself in just a few years. The savings result from intelligent control of various heating circuits and the utilisation of low-cost power rates. Operational safety also is improved.

Noise Reduction

Reduced noise levels are always welcome, and in many urban locations sound requirements are being tightened. The Ammapax® Flue Noise Suppressor is economical and easy to install. It’s effective, too, with noise pressure levels reduced up to 20 dB. The suppressor does not impact daily production.

Low Temperature Mixes

Lower temperature asphalt delivers multiple benefits – including reductions in fuel usage and emissions. A retrofit enables the use of foam bitumen, waxes and other additives. Special bitumen and alternative mixing cycles can be utilised as well.

Technological Improvements

Burners

New burners feature built-in technological advantages and engineering that improve cost efficiency and production. An updated burner allows the use of multiple fuel types and reduces noise levels. The retrofit is fully integrated to precisely match the existing plant. The design is robust with long life.
