Heating elements are used to maintain temperature and reduce humidity levels in electrical panels, automation cabinets, ATMs, payment terminals, and other electronic devices. In the past, incandescent bulbs were used for this purpose, but it is clear that this method does not meet the modern stringent requirements for electrical equipment and electronics. Nowadays, almost all manufacturers are switching to PTC heaters, which not only provide heating but also guarantee safety and durability of operation.

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

Due to the high demands placed on cabinet heaters, Plastim has devoted the utmost attention to the selection of component suppliers. The supplier of the PTC heaters is, for example, the same as Schneider Electric, and the terminal block for the 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 retains its shape and does not deform, but it also does not emit odors and therefore does not release harmful carcinogenic substances into the atmosphere. I agree that this approach in the selection of suppliers favorably distinguishes Plastim heaters of high quality from cheap Chinese analogs.

To ensure that the temperature of this heating system is maintained automatically, you need a simple bimetal thermostat or a more complex thermostat. Both devices are available for purchase on our website:
