The heaters of the PTLCLI Series are designed specifically for domestic heating appliances (radiators and towel rails) and are provided with a Class I insulation - according to CEE EN 60335-1 - and with an IP64 protection rating. They are built with the PTC (Positive Thermal Coefficient) technology, which means that they can provide a heating power functional to the temperature, thus giving maximum power at a lower temperature and reducing the power output as the temperature nears the reqired value. This system guarantees several advantages: Safety: meaning that in the worst working conditions – i.e. should the radiator run empty – the power absorbed by the PTC drops to insignificant levels, thus avoiding the risk of damages to the heating element. Savings: in the PTC system the temperature is self regulating which eliminates the need for further safety devices such as over/temperature cut/outs and thermalfuses. Smaller dimensions: their different internal construction allows a reduced dimension of the heaters in comparison to the traditional models. Easy mounting: PTC heaters can work equally well in any mounting position (vertical or horizontal). AFS Product Line: Class I - PT CL I
