Short Path Evaporators used in Chemical Industry

ILUDEST® Short Path Evaporator KV 80

Short Path Evaporators are used in chemical industry for the production and processing of macro-molecular substances. Because of the thermal sensitiveness of products, this separation method is applicable. The sample to be distilled is exposed only for a very short time to the heating substances because the film, created by the wiper, can evaporate very quickly. The residence time of medium on the heating surface is a matter of seconds, thus essentially less than in a reboiler flask, circulating evaporator etc. The evaporated product (operation pressures down to 10-3 mbar and temperatures up to about 300°C) has to pass a “short path” to the condenser only, which is located in the middle of the evaporator.
Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m².
Evaporators in stainless steel can be heated by a heating jacket to higher temperatures with more heat transfer area for higher throughputs.
