Enclosure heaters
Enclosure heaters are used to prevent the formation of con-
densation inside the enclosure and maintain a constant
minimum operating temperature (e.g. when the system is
switched off overnight).
Rittal TopTherm heaters, with self-regulating PTC technology,
ensure constant heat distribution with outputs in the range;
of 10 W – 150 W, for those not fitted with a fan and 250 W –
800 W for fan assisted variants. For heaters with fans, a
minimum safety clearance of 300 mm at the top must be
observed, and the equivalent figure for heaters without fans
is 100 mm. In each case the thermal safety clearance to the
sides of 60 mm, and 100 mm at the bottom is required.
