The most common mode of failure in stacks is vibration due to Vortex Shedding, here are some common Engineering solutions to address this vibration in an economical manner.


Meca provides damping pads for stacks. Generally these are an economical solution for stack heights from about 50 ft [15.2 m] to 150 ft [45.72 m].

It’s a very easily solution to implement on New Stack designs. Damping pads have been used for about 40 years, and have proven to be very reliable.


Tuned Mass
Dampers (TMD)

A Tuned Mass Damper (TMD) is device that is added to the top portion of the stack that increases the damping of the stack, which will suppress wind induced vibration.


Tuned Liquid
Dampers (TLD)

Meca has partnerships with companies that design Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD). These are typically used on stacks that are 150 ft [45. m] and taller. There are many factors that determine whether a TMD or TLD is more appropriate.
