Modernizations and modifications

Your equipment has got potential

Our OTTO JUNKER Service Team is specialized in carrying out modernizations and modifications of older plants in order to make sure that you always have an ultramodern plant at your disposal in your production process.

The modernization and extension of existing furnace plants offer major opportunities in order to increase your efficiency. This approach offers potential for energy saving, increased performance, improved operational safety and reduction of downtimes. Compared to buying new equipment, the costs are considerably lower and the installation times shorter. It therefore makes sense to check this option thoroughly. Solid technology combined with proper maintenance and our reliable service are the key to a permanently successful operation of your equipment.
