Is it a crawl space rated one? Ive been using my Titan 60 for almost three years now and no issues.
Yup, they all have been crawlspace-rated dehumifiers. Actually, the longest-lasting dehumidifier I've had is a Danby 70 pint model from Costco that is definitely not rated for this use, but I bought as a backup when all of my other machines were under repairs. The compressor used to run all the time and still works after 2 years. Maybe the constant on-off cycling of the compressor causes these machines to fail? --Then again, that's what these crawlspace-rated machines are made to do.
Guess the other question is how good is your sealing? If you’re getting a ton of moisture in it has to work that much harder.
The sealing seems fine - all the vents are spray-foamed and the door is lined with weather rubber sealant, vapor barrier etc. It is as close as you can get without it being "climate-controlled" crawlspace.
Regardless, I think it's important to note that the expensive dehumidifiers have all failed after 6 months and the ones from Home Depot are all running without issues. Yes, the Home Depot ones don't remove as much moisture but just working is good enough for me at this point.

Does your vapor barrier cover 100% of the floor? Have you taped the seams? How about downspouts and drainage around your home?
I bought very thick vapor barrier from a place in Fuquay. I want to say its like 16 mil and covered the floor 100%. I taped the seams and then installed the dehumidifier. Crawl space went from 80% down to 50% very quickly. The next year I bought wall curtain from yourcrawlspace.com out of SC and did all my walls and piers. All taped to the vapor barrier on the floor. Then had my cripple walls in the crawl space insulated as well to help with heating/cooling. On the outside I ran all my drains underground away from the house and installed oversized gutters.
If your machines are running a lot then I would definitely focus some time and money to keeping water out of the crawl. Handle the outside first, then look at the inside. The wall curtain material was pretty awesome. It attaches to the walls with caulking so you dont have to mess with drilling into it or anything. You dont even have to clean the walls before applying the caulking. Apply caulk, press curtain on wall, and tape to the floor.
Vapor barrier covers entire floor with taped at corners, but not in-between seams. All downspouts are oversized and tubed over 20ft away from the house. Have made sure no pooling of water occurs when it rains a lot. I installed the tubing away from the foundation and extra vapor barrier items after buying this house.
Regardless, these expensive machines fail and the cheap ones keep running. And this is just me who actually cares about house maintenance. I don't think the rest of the neighborhood even goes inside their crawlspace!
