Updating our terms and conditions


The expansion of our existing business with the 'Service for power plant- and marine diesel engines", as well as changed legal regulations and requirements made it necessary to revise our general terms and conditions.

These updates were completed in July 25th 2016 and our updated terms and conditions were published in the download section of our website to be viewed and downloaded from our business partners. I addition, but only upon request from our business partners we will be pleased to provide these new documents by official post.
