Temperature control is necessary in many industrial production processes, such as ovens, injection, blow molding and extrusion of plastic materials, metal production, chemical, pharmaceutical and other processes. The thermoregulation control is obtained by implementing the control loops on board of thermoregulators or on board of P.L.C. and proportionally piloting the heating elements, whether they are electric resistances, gas burners or other. Tekna Automazione e Controllo uses thermoregulation components that allow temperature control in the various phases of the production processes in which it is necessary.

The SCR modules, in the different current capacities, are similar to semiconductor switches that allow to power the heating resistors. These modules are controlled by the temperature regulators and enable current to pass through the resistances and, therefore, their heating.
Compact low current SCRs, such as Crydom or Omron, and higher power SCRs, such as AEG or Eurotherm, are available with electronic load breaking controls.

Digital thermoregulators are used to achieve temperature control in heating or cooling processes, such as extrusion lines, plastic injection molding machines, thermoforming machines, rubber presses, packing and packaging machines, processing plants for the food industry, cooling units, climatic cells and test benches, ovens, painting systems, etc.
