Product Features
Number of program curve segments
- The intelligent control system supports flexible programmable temperature curve settings with multiple adjustable segment groups, including 50 segments in Group 1, 22 segments in Group 2, and 8 segments in Group 3. This multi-group configuration allows users to customize complex heating and cooling processes according to different production or research requirements.
- Each programmable segment can be independently adjusted, enabling precise control of temperature ramps, holding times, and cooling stages. The system is suitable for advanced thermal processing applications requiring multi-stage temperature profiles and accurate process management.
- With flexible programming capability and stable control performance, the furnace ensures smooth thermal transitions, improved process repeatability, and higher production efficiency for laboratory and industrial high-temperature applications.
Pressure protection
- The furnace is equipped with an intelligent pressure safety protection system specially designed to prevent hazards caused by blocked exhaust ports or abnormal internal pressure buildup. The system continuously monitors furnace pressure through an electric contact pressure gauge or high-precision pressure sensor, ensuring stable and safe operation during high-temperature processing.
- When excessive pressure or exhaust blockage is detected, the control module automatically closes the electromagnetic intake valve and simultaneously activates the electromagnetic exhaust valve for rapid pressure release. At the same time, audible and visual alarms are triggered to immediately alert operators of abnormal conditions.
- This automated safety mechanism effectively protects the furnace structure, heating components, and control system from pressure-related damage. By combining real-time monitoring, automatic response, and intelligent alarm functions, the system enhances operational safety, improves equipment reliability, and ensures continuous stable performance in demanding industrial and laboratory applications.
control
- The system adopts advanced closed-loop control technology combined with thyristor module phase-shift triggering, enabling continuous and precise adjustment of voltage, current, and power output. It supports constant voltage, constant current, and constant power operating modes, ensuring flexible and stable thermal control for various high-temperature processes.
- A dual-loop regulation structure is implemented, with the current loop functioning as the inner control loop and the voltage loop serving as the outer control loop. This coordinated design provides fast dynamic response and maintains stable operation even under sudden load fluctuations or changing process conditions.
- When excessive load or overcurrent conditions occur, the system automatically limits the output current within the rated range to protect the voltage regulator and heating elements from electrical overload and surge damage. At the same time, the voltage loop continuously participates in intelligent regulation, maintaining stable output with sufficient adjustment margin for reliable performance.
- This intelligent control architecture enhances operational safety, improves heating accuracy, reduces component stress, and extends equipment service life, making it highly suitable for precision industrial heating and laboratory thermal processing applications.
