PTC AED cabinet heater is a self-limiting

PTC AED cabinet heater is a self-limiting,

earth-shielded heater with a build in controller.

This heater is based on a robust heater technology with a proven

track record from many years in automotive applications.

The heating circuit is not only relying on one continuous circuit.

The heater consists of several hundred parallel PTC paste-heating

elements that ensure long lasting performance even if the circuits

are locally damaged for some reason.

This feature of the PTC paste adds an extra safety to the product that eliminates the risk of overheating. It still

requires a temperature controller to give the needed heat and temperature into the AED cabinet.

The nature of the PTC heating elements will give the heater slightly diferent characteristics than a conven-

tional fxed wattage heater. The start power will be higher but will fall quite quickly to some point along the

power curve. The fnal value depends on the surface temperature as well as the temperature measured in the

control unit that is directly placed on the left bottom corner of the heating element. This controller regulates

the power supply by switching on and of depending on its measurement. For easy installation the heater is

equipped with an adhesive backside for easy installation in the AED cabinet. Additional holes are placed for

additional fxation of the heating element to the backside of the AED cabinet.

PTC (Positive Temperature Control) refers to the

characteristic of the unique PTC paste used to

generate the heat in the ROTAID – PTC AED cabinet

heater. The resistance in the heat generating paste

will increase with temperature to such an extent

that it is limiting the power efciently above 30 °C.

This means that the heater will give more power

when needed at low temperatures and less power

as the temperature increases.
