This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. One of its outstanding characteristics lies in its safety performance. Even when the fan stops running due to a fan failure, the PTC heater will automatically drop its power sharply due to insufficient heat dissipation. At this time, the heater's surface temperature is maintained at about the Curie temperature ( Normally around 250℃), so as not to produce electric heating tubes.
The appearance of similar heaters is "redness". In the experiment, this temperature control accuracy can reach the range of ±2℃～±0.2℃.
The internal high-pressure system of this kind of equipment can provide the DCS system with alarm signals such as heater running, high temperature, malfunction, shutdown, etc., and can also withstand the operation slogans issued by DCS such as automatic and shutdown, and it has added a reliable electric heater system. Safe monitoring and installation, but the price of this electric heater is relatively high.
Electrical equipment has multiple associated interfaces, which can effectively monitor the heat transfer oil pump, the temperature flow of the heat transfer oil, and the pressure of the internal high temperature voltage at any time. Thus, the explosion-proof electric heater is more energy-saving.
