“You can’t expect what you don’t inspect” is a very popular saying because it’s true. We have found all sorts of things that hinder performance or reliability during our inspections. Often what is considered “normal” in a dryer, may in fact be normal, but it isn’t right and could be improved tremendously.
Inspections are the #1 defense against unplanned shutdowns. Dryer operators are out there every day walking around the system, taking samples, and checking everything out. Alert and knowledgeable dryer operators will notice when something isn’t right and can pass the information along to the right channel. But, every once in awhile, you will need a dryer expert that knows what to look for and where, and whether a certain issue should be dealt with immediately or can be left alone for a time.

- Strange noises – thumping, woofing, clunking, squeaking, etc
- Vibration and shaking
- Frequent fires and/or explosions
- Pretty much anything else having to do with a dryer system
What can you expect? We have been able to increase lifespan, capacity, structural integrity and seal effectiveness when plants follow our recommendations based on our inspections. Plants have seen decreased maintenance cost and decreased down time after implementing our strategies.
