We
published information on this in July of 2021, but got some new more specific
information that 100% indicates that Dover/TKE will not be supporting the Dover
DMC platform any longer. This is very
important for my buildings in the Chicago area that have Dover DMC equipment,
when the boards are gone, they will be gone.
There are some 3rd party companies that may continue to
support the system, but now is the time to start considering elevator control
modernization if you have a Dover DMC.
What’s the story? Dover Elevator installed elevators from 1955 to 1999 and
was the 3rd largest elevator company prior to selling to
Thyssen Krupp[now known as TKE]. After Thyssen Krupp bought Dover, they
branded the TK name on it prior to moving to a totally different platform
called the TAC 20. The Dover DMC was a wonderful, very reliable software-based elevator control system. While the Dover DMC had some drawbacks, it has
been a very reliable work horse for many buildings. Recently Thyssen, or TKE, decided to discontinue support for the Dover DMC and will no longer manufacture
solid state boards.
Who this impacts – If you have a Dover DMC 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 3rd 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.
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. If your CLC board, selector board,
door board or any other board goes out, do they have a
replacement? 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.
