What distinguishes TYA HL thyristor controllers:
In applications such as hardening, metal sintering, ceramic firing, or crystal growth, precise temperature control at every stage of the heating and cooling cycle directly translates into the quality of the final product. The TYAHL301 (single-phase) and HL303 (three-phase for non-linear loads) thyristor controllers allow you to select the operating mode (phase angle control or pulse groups) to match the characteristics of the heating elements – resistive, ceramic, or IR radiators. This makes it possible to maintain an even temperature distribution without overheating or local overloads. Integrated diagnostic tools facilitate process monitoring, and broad communication compatibility improves integration with existing control systems.
In flow systems, where the medium (air, water, gas) dynamically changes its temperature and speed, smooth and fast power control is essential. TYA HL301 and HL302 eliminate the step switching effect known from classic SSRs, ensuring smooth operation even with frequent changes in operating parameters. HVAC systems, process water heaters, and duct heaters thus operate stably, economically, and without thermal vibrations. Additionally, real-time power modulation reduces heater wear and ensures uniform heating throughout the system.
In thermal oil heating systems, which often operate in closed circuits and under high loads, both precision and safety are important. The TYA HL303 controller has been designed with these conditions in mind: it supports both resistive heaters and induction systems, ensuring smooth power delivery even with non-linear loads. Stable temperature allows you to maintain process conditions in chemical reactors, reduce energy consumption, and minimize the risk of overheating. Thanks to Modbus TCP, EtherCAT, and PROFINET interfaces, the controller easily integrates with higher-level automation systems.
In vacuum furnaces, furnaces for sintering in a protective atmosphere, or installations for the production of special alloys, the precision of temperature control has a direct impact on the properties of the material. The TYA HL303 three-phase thyristor power controllers ensure a stable power supply even at voltages up to 690 V and currents up to 800 A. The ability to adjust the operating mode to the load characteristics reduces the risk of overloads and guarantees process continuity. The oscilloscope function in the configuration program and data logging support rapid analysis of irregularities. This is particularly useful in processes that cannot be interrupted, such as vacuum metallurgy or technical ceramics production.
In applications that require continuous operation under heavy loads, such as steam heaters or multi-zone oil systems, the TYA HL301 and HL303 provide stable control without the side effects typical of SSR relay solutions. The ability to distribute the load across multiple zones and manage power consumption (e.g., via a master EMS or SCADA system) helps maintain energy security and optimize energy consumption.
Applications involving the melting of glass, aluminum, or copper require high temperatures and long holding times. The TYA HL301 and HL303 enable control based on voltage, current, or power, allowing the amount of heat supplied to be precisely adjusted to the characteristics of the batch. Maintaining the temperature within a narrow range directly translates into product quality and process stability. The ability to connect to SCADA or EMS provides full visibility of parameters and ongoing control.
Modern hybrid ovens, combining gas and electric heating, require precise power management in different temperature zones. The TYA HL302 is an economical three-phase solution that allows independent control of individual heaters. The peak power limitation function reduces energy costs while ensuring repeatability of baking cycles and compliance with sanitary standards.
In Power-to-Heat applications, electricity, often from renewable sources, is converted into heat and used, for example, in buffer tanks, steam boilers, or oil heaters. Communication with SCADA, EMS, or cloud systems (e.g., via Modbus TCP, PROFINET, or EtherCAT) enables seamless integration with digital automation architecture.
