STEP 2 - (continued)
Protective screens
Screens on both sides of the heater prevent any
accidental contact by personnel or tools with electrically
de-energized but still "live" coil elements.

Bottom control box
In special conditions, where there is not enough space to ensure
proper installation and maintenance, Thermolec can supply a
bottom control box designed to maintain the horizontal
orientation of open coil elements.
Dust-tight Control Box
A dust-tight control box can be supplied by Thermolec when local
codes require it. The control box has all the openings sealed and the
cover is gasketed. When SCRs or fuses are installed in a gasketed
control box, since there is no opening allowed for proper cooling, the
box has to be oversized.
