Heater with screens
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 hor
izontal
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 bo
x 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.
