Even though we have established our market position as a company specialized in testing and commissioning of nuclear facilities, our portfolio contains also activities associated with construction and manufacture preparation, manufacture and installation. We offer these activities also as a standalone service in any engineering sector (also outside the scope of energy sector). We provide installation and manufacturing schedule, as well as logic sequencing and coordination of individual works with links to functional and complex testing within the frame of applicable legislation and client’s requirements.

We have our own fully equipped shop

Preparatory, pre-assembly, manufacture and machining works are carried out at our own manufacture site by highly qualified, certified and multilingual employees at all levels of our activities. Our services include manufacture of thermal insulations of technological equipment and subsequent installation of the insulation by our in-house fitters. The thermal insulation is manufactured by our own technology directly at our manufacture sites.

Manufacture and installation of piping insulations

For this purpose, we procured a high quality machine for the production of sheet metal parts for thermal insulation. This machine has all the attributes of the latest technology. A dedicated team was trained to work with this special equipment and improve its expertise:

 

  • We offer complex sheet metal working services including surveying, bidding, consultancy, material supply and installation of sheet metal systems plus warranty and post-warranty service.
  • We manufacture thermal insulation, cold insulation, HVAC distribution systems including surface finish with heat saving, environmental protection, as well as health and safety measures to prevent burn injuries in mind.
  • In sheet metal insulation manufacturing, we use the latest technology, specifically, the Swiss-made MABI Bingo 16-Z EVO, MABI Logo, MABI 4B and MABI 4QS.
  • Further sheet metal parts processing is done using METALLKRAFT® equipment and equipment procured from První hanácká BOW, spol. s r. o., Bři Švarcové, s. r. o., SEMET, s. r. o., etc.

The engineering part does not comprise only of construction aspects, but also technical preparation of works and machinery equipment. We manage the project in its entirety, as well as provide final inspections. Our welders have:

 

  • Welding certificates for welding of materials (classes 1 – 8), using welding methods: 111, 141, 141 – orbital welding.
  • Welding certificates for pressure equipment welding in compliance with directive PED 2014/68/EU Annex 1,3.1.2.
