Heating elements are used to maintain temperature and reduce humidity levels in electrical panels, automation cabinets, ATMs, payment terminals, and other electronic devices. Previously, incandescent lamps were used for these purposes - but it is obvious that this method does not comply with modern stringent requirements for electrical equipment and electronics. Today, almost all manufacturers are switching to PTC heaters, which not only provide heating but also guarantee operational safety and longevity.

All heaters are equipped with electronic protection against surface overheating, which provides an additional guarantee of safe operation.

Due to the high demands placed on enclosure heaters, Plastim paid utmost attention to the selection of component suppliers. For example, the supplier of PTC heaters is the same as Schneider Electric, and the terminal block for electrical connection of all components is custom-made by the Italian company KORNER. The plastic from which this block is made has a very important property: when heated, it not only maintains its shape and does not deform, but also does not emit any odors, thus releasing no harmful carcinogenic substances into the atmosphere. You will agree that such an approach to supplier selection favorably distinguishes high-quality Plastim heaters from cheap Chinese analogues.

To ensure automatic temperature maintenance with this heater, a simple bimetallic thermostat or a more complex temperature controller will be required. Both devices can be purchased on our website
