End Of Life/Obsolete Elevator Equipment – TAC 20/TAC 22

 

This is big news for buildings with Thyssen Krupp/TKE or TK TAC 20 or TAC 22 controller platforms.  In a letter dated 1/6/25 sent to buildings with this elevator installed indicating the CPU board has been officially discontinued.  These are not old elevators, they where installed in the 2000’s and 2010’s

 

What’s the story?  Thyssen Krupp/TKE now TK is retiring their TAC 20 & TAC 22 product line.

Who this impacts – If you have a Thyssen Krupp/TKE/TK TAC 20 or TAC 22 control system you should begin putting money away for a control modernization.  There are still parts available, we have parts, but when they are gone, they are gone. 

Are parts still available? – Yes and no.  There are 3^rd party manufacturers that stock some of the boards.  There are a few elevator solid state board repair shops that will repair the boards.  The warning with any board repair is that while the intention is to be successful, sometimes board repairs are not successful or take a few tries.  If you don’t want these challenges, replace the elevator controller prior to going down this painful road. 

Is software available once your replace boards? – Yes and No.  We have ordered software for elevators and it has taken 4-8 weeks to get.  Why does this matter?  Sometimes when you are switching boards you will need updated software or the original software to load on the control board.

Take away – If you have one of these controllers in your building get a plan together with your elevator contractor.  See if they have replacement parts and how many.  When it rains it pours, be aware that there are a lot of these out there and if a few have issues at the same time and require spare parts, you are pulling from the same spare part pool which is finite.
