Companys of Heat Pump Dryer for Sludge Drying

That sounds like an unusual application for heat pumps. Perhaps it is done, but is sounds expensive!

You will be asked questions such as, "How much sludge are you drying and how fast?"

You may also be asked about the properties of this sludge. One important question might be, "Is this sludge flammable?"

Is there some reason that you can't dry it in the sun? Something must make it special if you want to spend all of that money using the energy required for a heat pump. Little information = No answer!
