New Agent in Italy.


Welcome to our new Agent in Italy

SIRN S.R.l is a well-known and family owned Company. The company have more than 50 years in Business.

The company has always stood out for its drive towards innovation, quality and safety. The HQ is in Trieste and a local office in Genoa.

As an agent of foreign companies, SIRN was the first to introduce cathodic protection against corrosion and inert gas fire prevention systems in Italy.

Today it is the agent and distributor exclusively for Italy to some of the best-known companies in the world in the field of machinery and products for the nautical sector.

Silentor is exited about the cooperation agreement with Sirn S.R.L, and we are looking forward to the challenges ahead

Welcome to Silentor!





















Svend Frederiksen is leaving the board at Silentor.


After more than 2 decades as a board member at Silentor, Professor Emeritus Svend Frederiksen has decided to withdraw from the board. We would therefore like to thank Svend for his enthusiastic and energetic work for Silentor. 

Not only as a board member but also as a highly skilled consultant giving advice in regards to many different technical issues, Svend has helped Silentor during many years. 


As son of the founder of Silentor, Professor Eyvind Frederiksen, Svend assisted his father back in the 1950s carrying out the first laboratory tests, when developing the Silentor silencer technology, as well as he among other things carried out noise measurements of exhaust noise from the old MZ locomotives.


Later Svend became a professor in District Heating at Lunds University in Sweden for many years, but also during these years Svend was always ready to assist Silentor both as regards research and development as in specific customer cases.


We hope that Svend will enjoy his retirement and still have time to a chat once in a while, when we meet challenging technical problems in the future.
