Why PTC heaters are so important

PTC heaters are composed of PTC ceramic heating elements and aluminum tubes. The advantages of this type of PTC heating element are low thermal resistance and high heat transfer efficiency. PTC materials have temperature self limiting properties, can automatically maintain a constant temperature, and are also relatively energy-efficient electric heating elements. Due to its temperature self limiting characteristics, using PTC heaters is very safe and will not cause overheating or "redness" like electric heating tube heaters under any circumstances, thus avoiding safety hazards such as burns and fires.

PTC heaters for industrial use can be applied in electrical equipment cabinets and switch cabinets to ensure a stable heat source in the internal space, balance day night temperature differences and humidity changes. The temperature difference caused by temperature changes can cause moisture in the air to condense into condensation, which can easily lead to rusting of electrical components. The working principle of the heater is to increase the temperature in the air during operation, reduce the humidity in the cabinet space, and achieve the effect of evaporating water vapor. Then, it is discharged outside the cabinet through air circulation, keeping the cabinet dry and preventing condensation from forming.

Practical application examples of PTC convection heaters

DBK has been producing high-quality heaters for different industries for many years. Our PTC heaters can be installed in various applications, in addition to the switch cabinets and electrical equipment cabinets mentioned above, and are often installed inside ATM machines. The main function is to keep the banknotes dry and allow the machine to operate normally in low temperature environments. Due to the malfunction of many electrical components at low temperatures, ATM machines with display screens require heater protection to prevent screen frosting. Our heater can provide heating and dehumidification functions in the cabinet, and the PTC heater, which is safe to use and has automatic temperature control, can effectively control the temperature without damaging banknotes or other electrical components, making it an indispensable part of such applications.
