The patented tube type falling film OT Concentrator (Outside Tube Concentrator) is designed to perform without plugging.
The good heat transfer is achieved by excellent liquor distribution on the tubes from the distribution plate above the tube bundle. Steam is introduced into the tubes at the bottom. This results in complete countercurrent flow and desuperheating of the incoming steam by the down flowing condensate. In order to minimize any kind of scaling the bottom tube sheets can be inclined to prevent any gathering of crystals on the tube sheet. If necessary, both sides of the heating surfaces can be washed.


Steam at different pressures can be used

If any inspection is required or any mechanical failure takes place, it is possible to go inside for checking and fixing without any disassembly of the fixed constructions of the body. This is possible because there is an open space with platforms and ladders in the middle of the OT Concentrator.
