[Ca...] Posted June 27, 2019 Share Posted June 27, 2019 As I was cleaning up and organizing the lab this morning, I notice my air dryer is (or has) overheated. It doesn't seem to be actually "doing" anything right now. Usually it hums like a college mini-fridge. I've put everything on hold, and powered it down for now. I'm going to turn it back on in a few minutes, hopefully it will cool down, although it doesn't seem hot, or ever warm, as best I can tell with an IR thermometer. Any thoughts, or advice would be great!Dryer.PNG Link to comment Share on other sites More sharing options...
[Ch...] Posted June 27, 2019 Share Posted June 27, 2019 I have one trending in that direction right now. I'm thinking that the air is too wet and needs a filter change? I know I have the manual somewhere. Link to comment Share on other sites More sharing options...
[Ch...] Posted June 27, 2019 Share Posted June 27, 2019 It is a dewpoint indicator Link to comment Share on other sites More sharing options...
[Ca...] Posted June 27, 2019 Author Share Posted June 27, 2019 Also, Am I playing with nuclear fire by running the CMM without the dryer working properly? I've been assured by the owner that our shop has other drying systems in place before the air gets to me. Link to comment Share on other sites More sharing options...
[Ca...] Posted June 27, 2019 Author Share Posted June 27, 2019 I saw that, I found the manual. It's pretty clean, considering it's a couple years old. Is the humidity gage monitoring air going in, or air going out I wonder? Link to comment Share on other sites More sharing options...
[mi...] Posted June 27, 2019 Share Posted June 27, 2019 I have had to run for a couple of weeks without our air drier in place and caused no problems but we have multiple line driers in place. Your biggest problem is going to be if your air lines drop down from the ceiling after the air line driers. the problem is when the air lines run from high temp on ceiling then temp drops several degrees running down to the floor area condensation will occur and create water in your air lines.

[Ri...] Posted June 27, 2019 Share Posted June 27, 2019 Well I hope nothing is wrong because yours looks exactly like mine. 😮 I presumed that it meant that the air is dry! I've genuinely never heard or seen it do a thing. The light is illuminated green, that's about it. Link to comment Share on other sites More sharing options...

[Ow...] Posted July 16, 2019 Share Posted July 16, 2019 The CMM I work with the most was installed before my arrival. They put the air-dryer 7ft in the air attached to a post. I know the humidity indicator must play an important role but, in 5 years of running it, prior to me reading this post, I never knew the indicator existed... : 🙄 Link to comment Share on other sites More sharing options...
[Ch...] Posted July 17, 2019 Share Posted July 17, 2019 Update, One of my dryers was running a little humid. It looked exactly like Casey's and Richards picture. I had maintenance look into it. It turns out that there is a resent switch on the fan but you have to take the unit completely apart to get to it. With the fan now reset, I am running on the lower end of the green just like my other one. If you can't feel the fan blowing then it has probably gone out.

[Ri...] Posted July 17, 2019 Share Posted July 17, 2019 Nice find! I will check this first thing when I get in tomorrow. Thank you! Link to comment Share on other sites More sharing options...
[Ca...] Posted July 23, 2019 Author Share Posted July 23, 2019 Mine has a few problems. First the fan had essentially disassembled itself. The lock ring which held the whole motor together gave up the ghost. After maintenance replaced the fan, I discovered the power switch had literally started to disintegrate,I have no idea how, but now there's one of those on order. I don't know how much more work to do on this thing before it would have been cheaper to just buy a new one.... Link to comment Share on other sites More sharing options...
[Ca...] Posted August 7, 2019 Author Share Posted August 7, 2019 The fan and power switch have been replaced, and the dryer still doesn't seem to be "doing" anything. I thought I remembered seeing something about a reset switch, or manual run button, but now I'm not so sure. It's a Wilkerson WRD10 Link to comment Share on other sites More sharing options...
[Ri...] Posted August 7, 2019 Share Posted August 7, 2019 Please sign in to view this quote. I couldn't find a thermal reset switch on mine either. Luckily ours was brand new so I was able to get an RMA. I think we have discovered a design flaw for Parker Hannifin Link to comment Share on other sites More sharing options...
