For
added cooling, NEPSI's capacitor banks and harmonic
filter banks may be equipped with one or more
thermostatically controlled exhaust fans. Typically
these exhaust fans are located on the inside of
the enclosure and force air to circulate through
the front of the enclosure to the side panel(s)
as shown in the pictures to the left and right.
All
louvers are backed (covered) with a stainless
steel mesh to prevent rod and rodent entry. For
dusty environments, washable mesh filters can
be supplied to reduce the entry of dust.
Both
the fan and the louvers can be designed to be
removable without entry into the medium voltage
compartment. This option is not standard, and
should be specified.
