Product Features

Furnace Body Structure

The furnace adopts an advanced double-layer air-cooled body structure designed to enhance operational safety, thermal efficiency, and equipment durability. Strategically positioned air-guiding baffles create a continuous cooling airflow throughout the furnace shell, ensuring efficient heat dissipation during high-temperature operation.
The circulating cooling air effectively removes excess heat from critical electrical connection points and conductive tabs of the heating elements before being discharged from the furnace body. This optimized cooling process significantly reduces the risk of high-temperature oxidation, helping maintain stable electrical performance and extending the service life of key heating components.
In addition to protecting internal components, the air-cooled structure lowers the external surface temperature of the furnace, creating a safer and more comfortable working environment for operators. The efficient thermal management system also improves equipment reliability, minimizes maintenance requirements, and supports long-term stable operation. This design makes the furnace particularly suitable for demanding laboratory research, material development, sintering, and industrial heat treatment applications requiring continuous high-temperature performance.

Protect

The furnace is equipped with an integrated modular control system designed to deliver high-precision temperature regulation and exceptional operational reliability. The advanced control architecture improves response speed and control accuracy, ensuring stable thermal performance throughout the entire heating process.
A dual-loop control and protection design continuously monitors critical operating parameters and automatically adjusts system output to maintain optimal performance. This intelligent system effectively prevents temperature overshoot and undershoot, ensuring accurate process execution and improved product consistency.
Comprehensive protection functions include thermocouple break detection, phase-loss protection, overvoltage protection, overcurrent protection, overtemperature protection, current feedback monitoring, and soft-start protection. These safety mechanisms help safeguard heating elements, electrical components, and furnace structures from unexpected operating conditions.
By combining precise control with multi-layer safety protection, the system enhances process stability, reduces equipment downtime, extends component service life, and ensures safe operation in demanding laboratory and industrial high-temperature applications. The integrated modular design also simplifies maintenance and improves long-term operational efficiency.

control

The furnace adopts an advanced SCR closed-loop power control system that supports both phase-shift and zero-crossing triggering methods, enabling continuous and precise adjustment of voltage, current, and power output. The system can operate in constant-voltage, constant-current, or constant-power modes, providing flexible control for a wide range of high-temperature processing applications.
A dual-loop regulation architecture is utilized, with the current loop serving as the inner control loop and the voltage loop functioning as the outer control loop. This intelligent design allows the system to respond rapidly to load fluctuations, ensuring stable and accurate power delivery throughout the heating process.
When sudden load changes occur or current demand exceeds the preset limit, the controller automatically restricts the output current within the rated operating range. Simultaneously, the voltage loop participates in dynamic regulation to maintain stable operating conditions and prevent excessive electrical stress on critical components.
This protection mechanism effectively safeguards heating elements from overcurrent and overvoltage damage, extending service life and improving overall system reliability. By combining high-speed response, precise regulation, and comprehensive electrical protection, the control system delivers exceptional heating accuracy, enhanced process stability, reduced maintenance requirements, and safe long-term operation for demanding laboratory and industrial thermal applications.
