Pressurized Explosion-Proof Oil Temperature Controller: A Safe High-Temperature Heating Solution up to 300℃
In industries such as chemical processing, new materials, lithium battery manufacturing, and rubber production, many production processes require stable, high-temperature heating under precise temperature control.
Meanwhile, some industrial environments may contain flammable gases or explosive atmospheres, creating higher requirements for equipment safety and reliability.
The Pressurized Explosion-Proof Oil Temperature Controller is specially designed for hazardous industrial environments. Using thermal oil as the heat-transfer medium, this high-temperature control unit can achieve a maximum operating temperature of 300℃. Equipped with a pressurized, explosion-proof ventilation and electrical control cabinet, the system maintains a positive pressure inside the cabinet by continuously supplying clean, compressed air, thereby preventing combustible gases from entering the electrical compartment.
The unit integrates a circulating oil pump, electric heating system, expansion tank, and intelligent temperature control system, providing a safe, stable, and efficient heating solution for reactors, molds, rollers, and other industrial equipment.
What Is a Pressurized Explosion-Proof Oil Temperature Controller? Compared with conventional oil temperature controllers, explosion-proof models are designed specifically for applications where flammable gases or hazardous atmospheres may exist.
The system is equipped with:
• Pressurized ventilation explosion-proof control cabinet
• Explosion-proof electrical components
• Continuous compressed air protection system
• Low-pressure alarm function
• Safety interlock protection system
During operation, clean compressed air continuously enters the electrical cabinet to maintain internal positive pressure. This prevents explosive gases from entering the cabinet and reduces the risk caused by electrical sparks or ignition sources.
This design makes the equipment suitable for industrial heating applications in hazardous areas requiring enhanced safety protection.
300℃ High-Temperature Thermal Oil Circulation Heating Principle
The 300℃ high-temperature oil temperature controller uses thermal oil as the heat transfer medium. The electric heater heats the thermal oil, and the circulating oil pump transfers the high-temperature oil to the target equipment.
The working process is: Electric Heater → Thermal Oil Heating → Circulating Pump Transfer → Equipment Heating → Thermal Oil Return Circulation
Compared with water-based heating systems, thermal oil heating provides:
• Higher operating temperature capability
• Excellent thermal stability
• No high-pressure steam generation
• Long-term continuous operation capability
Therefore, thermal oil temperature control systems are widely used in industrial processes requiring reliable high-temperature heating.
High-Precision Temperature Control with ±1℃ Accuracy
For industries requiring strict temperature consistency, temperature stability directly affects production quality.
The explosion-proof oil temperature controller adopts:
• PID closed-loop temperature control
• PLC intelligent control system
• High-accuracy temperature sensors
• Touchscreen HMI interface The system provides:
• Real-time temperature monitoring
