Anti-Condensation Heaters
Heating elements for dehumidification of sealed switchboards and control cabinets.
Due to temperature limitations on e.g. print and plastic cabinets it is important to use a heating element with a large surface and thus a low surface temperature. The condens heater is designed to meet these properties. The temperature limit (appr. 65°C) is integrated into the construction and the small physical measurements enables installation in most cabinets and switchboards.
The cooling fin profile has an optimal surface in relation to heat loss in circulation airflow. The element is made of black anodized aluminium which optimises heat conduction and emission.
Installation
The anti-condensation heater should always be mounted with the cooling ribs in vertical position. The best circulation is achieved by placing the heating element at the lower part of the cabinet.
Due to the element’s low surface temperature, the position in relation to other components in the cabinet is not critical. Although it is recommended to maintain 5 cm free space on the sides and approx. 3 cm free space to the bottom due to air circulation.
Construction
The cooling fin profile has an optimal surface in relation to heat loss in circulating airflow. The element is made of black anodized aluminium which optimises heat conduction and emission.
The anti-condensation heater is supplied with temperature limit or as a selflimiting construction where a PTC element supplies the profiles with power according to the surrounding temperature.
The small cabinet heating element is without thermostat and casted in silicone rubber. The element is supplied with tape for attachment onto the cabinet. Can be used in places where the available space is very limited. the element can be bent with a min. radius of 15 mm
