One of an attributes of quality Feryster’s products is their high reliability. An important factor affecting both the reliability and safety of the user, is the temperature at which the device operates. High operating temperatures may lead to chemical reactions with aging effects associated with material weakening and therefore dangerous operational situations - product failure or other hazards to user. Therefore Feryster, implemented to its production two UL certified electrical insulation (EIS) systems (in accordance with UL 1446), ie. class B (130°C) and class F (155°C). the electrical insulation system. These two IES consist of a list of specific insulation components, which has been tested by UL for chemical compatibility at sustained high temperatures. Products marked by Feryster respectively FER-130 and FER-155 are compatible with aforementioned EIS.
These two systems are officially recognized in the UL file number E481059 (OBJY2).
