HA04_P&C_R&DHeating appliances are increasingly managed by a very reliable but more and more complex control electronics, which has recently revalued a device deemed obsolete, the bimetal thermostat, to the ends of its safety in terms of cost and reliability.

Thermorex has been offering for some time on the market a highly interesting device for its clip application, to be installed directly on pipes, like the current NTC temperature probes, without having to prepare fixing plates by braze welding but simply using a steel clip.

The aluminium or steel base of the temperature-sensitive thermostat, to facilitate the temperature transmission between the pipe and the device, has been bent to make the two surfaces match as much as possible.

The thermostat is implemented in two versions: with plastic body for temperatures up to 175 °C or in ceramic for maximum temperature values of 425 °C. The fixing clip is made of steel, suitable for withstanding these exposures. Devices can be supplied with silver contacts with very low resistance value, even 5 milliohms, or with gold contact.

Currently the fixing clip to the pipe most used is manufactured for diameters of 18 mm, but upon demand it is possible to implement different diameters as well. R&D Components is the Italian office of Thermorex.
