Selection of explosion-proof and dust-proof ratings
Thread Content
I would like to ask the experts for any good suggestions regarding the selection of electrical and instrumentation equipment for the trichlorosilane synthesis workshop (where hydrogen, hydrogen chloride, and silicon powder dust are present) In particular, how is the selection of explosion-proof and dust-proof ratings determined?
If the instrument can be selected in intrinsically safe version, choose the intrinsically safe option (i); if not, choose the flameproof option (d). For electrical equipment, explosion-proof type (d) should be selected. The explosion protection rating must be at least Ee*a(d)IIC T4, and the protection level must be at least IP65.
