Production technologies in many industrial sectors involve the thermal treatment of raw materials or products within specific temperature-time regimes. For example, in mechanical engineering, automotive, or aerospace industries, chamber, shaft, bell, and muffle furnaces are used for such types of metal heat treatment as nitriding, hardening, annealing, and heating for stamping. These processes are ensured by the efficient operation of heating systems, the safety of which is guaranteed by equipment for monitoring and measuring the temperature regime of heaters. The main tool for automatic control of these systems is the heating control cabinet for thermal units, which houses controllers and sensors designed to measure and adjust the temperature of both the heater itself and the heated area. Such devices are supplied to the plant together with electrothermal equipment. Also, the production of control cabinets can be carried out in various configurations to order. The operation of the cabinet is ensured by microprocessor-based temperature control devices, power adjustment levers, and emergency protection automation. As a result of the implementation of this type of equipment, the competitiveness of the enterprise significantly increases, which is expressed in improved product quality, increased reliability of electrothermal equipment, and energy savings.
