Thin Film Evaporators are used in chemical industry for the production and processing of low-molecular as well as macro-molecular substances. Because of the thermal sensitiveness of products, this separation method is applicable. The medium which is to be distilled is exposed only for a very short time to the heating substances because the film, which is 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.

Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m².

Alternative design versions in stainless steel for higher throughputs are available upon request. This email address is being protected from spambots. You need JavaScript enabled to view it.

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 stainless steel can be heated by a heating jacket to higher temperatures with more heat transfer area for higher throughputs. This email address is being protected from spambots. You need JavaScript enabled to view it.
