The most important part of the Wilmod Sulfur Evaporator (WSE75) is the patented IR-heating element type SSV. When the IR heating element is working, the temperature stays below the inflammability of sulfur. This makes
it safe to evaporate sulfur. The WSE75 is easy to clean with the supplied SSV scraper. It is also possible to use a standard aluminum disposable scraper. This makes dosing of sulfur easier and the cleaning of the SSV.
