Multitech is a specialist of slender structures design and of various solution of damper (TMD of different types) and of Liquid damper. Our target is to support on long thern basis our partners and consequently we offer free evaluation of your practical problem.
  • Liquid damper
  • Tuned Mass Damper (cable coil, dashpot, viscous)
  • Laboratory testing
  • Stack design
Vibration Studies

In order to be more competitive Engineers design more and more lighter and slender structures to save weight and transport costs.

Structure becomes more economical but are also more sensitive to wind enduced vibration (vortex shedding), mecahnical induced vibration (fans); waves , earthquake.... Solution is given by the use of appropriate damper type or in some occasion in design modification. Multitech will be your partner to design the best economical structure+damper solution.

Tuned mass Damper

Multitech is designer of many types of Tuned Mass Damper. There is no universel damper. Some are excelent if ambient conditions are very aggressives ; some when modal mass are huge; some others when vibration cycles is low, some when vibration amplitude is smal or huge etc.

Each structure a is different and Multitech is able to give the most appropriate solution to any problem

Liquid Damper

Liquid damper can be used in many cases. They are not universal depending of frequency and level of vibration eccitation but they cover a large band of application.

In a lot of cases they can be used as a top pltaform or as connexion device between 2,3 or 4 slender structure and paly a second role and not be just a damper. Consequently they are generaly a global cheap solution.

Stack design

Multitech is a specialist to design slender structures for more than 25 years and has gained a lot of experience in the design of steel stack of any kind. Our goal is to provide the best economical solution :structure + transport + damper to give our partners the best competitivness on the international markets.

In the field of steel stacks we can design all types of stacks such as single flue; double skin, multiflue, refractory lined; steel lined, FRP lined, borosilicate lined, flake/resin lined etc and able to withand operation conditions ranging from 50°C to 850°C or more.
