This is used drying/dehumidifying container that we trialled for a metal oxide product we were producing before we realised the drying occured better without the encouragement of heat. 
The container is setup currently with the dryer/dehumidifier inside the container which does work (we wanted it this way for portability) but for those in a static application it will actually work ever better if the dehumidifier is located outside the container.
Unit specs:
 - Model: HRD07T
 - Dehumidification capacity: approx 30kg/hr
 - Max temp: approx 90deg c
 - Input power: 9.5kw (we have fitted a 3 phase 32amp plug)
 - Air volume: 6,000 m3/hr
Unit has been used for around 300hrs so it is still basically brand new and the whole system (including container) cost a bit over 25k USD when purchased in 2020. 
I have operating manuals and a great relationship with the manufacturer should there be any operational questions.
