We proudly serve. Countercurrent multiplication is the process by which a small osmolality difference between fluid flows in ascending and descending limbs, at each level of the outer medulla, is multiplied by the countercurrent flow configuration to establish a large axial osmolality difference. An example of a VFD application is the supply and exhaust fans for air handlers. To get around that, a separate air handler could be ducted in parallel with the furnace, feeding the same duct system (aka ‘pair of trousers to the old-timers, but not typically done for that reason). If you don't understand why, then you should not be buying parts from a wholesaler.
