We have supplied pressure equipment engineering to most leading steam boiler manufacturers in addition to Finland e.g. to Sweden, Poland, Hungary, China, USA and Russia.

Rantotek Oy is also familiar with process dimensioning as well as piping system, tank and steel constructing engineering. If the customer so wants, we are able to supply comprehensive and tailored boiler scopes from engineering to commissioning.

Rantotek Oy is systematically developing its operating procedures and an important part of Rantotek's quality comes from the use of the latest computer techniques and software. This makes co-operation with our customers flexible and fast. However, the long-standing expertise and professionally talented staff form the most important backbone of our company and ensure that all projects are executed with high quality standard.

Credit rating is a clear indicator of our success and reliability. The credit rating company Dun & Bradstreet has given Rantotek the highest AAA-rating, a class occupied only less than 5 % of Finnish businesses.
