Cabinet resistance heaters

Cabinet resistance heaters

Cabinet resistance heaters keep the internal ambient temperature positive in relation to the outside temperature in order to prevent condensation from forming. Cabinet resistance heaters can be installed in either a vertical or horizontal position. The shape and design of the units ensures optimal heat transfer inside the cabinet.  It is recommended to use multiple units with an average lower heating output for larger cabinets as opposed to one unit operating at a higher temperature. The dual unit design is not only more effective but provides a redundant unit. Consult with the Conteg Technical Team for additional information on how best to use cabinet resistance heaters to match your application and ambient environment.

It is recommended to install heaters in order to prevent condensation forming in the cabinet.
