Dimroth
A Dimroth condenser, also known as a spiral condenser, named after Otto Dimroth, is somewhat similar to the coil condenser; it has an internal double spiral through which coolant flows such that the coolant inlet and outlet are both at the top. The vapors travel through the jacket from bottom to top. Dimroth condensers are more effective than conventional coil condensers. They are often found in rotary evaporators which may use a more elaborate arrangement with several spirals. There also exists a version of Dimroth condenser with an external jacket, like in a Davies condenser, to further increase the cooling surface.
