I spend my spare time repairing old appliances, and also offer a bit of a warranty too. This dehumidifier would be good for commercial applications. I am able to make replacement parts if you want it more complete
This 1999 Kenmore dehumidifier is built akin to some commercial dehumidifiers. I bought this from the scrap yard and see it still has about 90% of its refrigerant in it. I straightened the bent fins and and am quite impressed with the build quality of the motor.
I have a side project of finding a way to make replacement water buckets for these, but modifying it to take a garden hose would be easier. Let me know which you prefer.
I'm also willing to take your old dehumidifier as trade. Ive had a fairly good success rate in repairing them.
