RT~300℃ High-Temperature Heating Circulator

RT 300℃ heating high-temperature circulator is a precision device specifically designed for high-temperature constant-temperature control, widely used in chemical engineering, pharmaceuticals, materials science, and new energy fields, capable of achieving stable heating and circulating temperature control up to 300℃.

Model: PLG-300/100

Temperature Control Range: RT (Room Temperature) ~ 300℃

Heater Power: 10 kW

The high-temperature circulation unit uses heat-transfer oil as the heat-transfer medium. In a closed system, electric heating elements raise the temperature, while a circulation pump forcibly drives the heat-transfer fluid, precisely delivering heat to target equipment such as reaction vessels, distillation units, and molds. Its key advantage is maintaining excellent temperature stability and safety even at elevated temperatures, meeting the stringent temperature-control requirements of industrial and research applications.



Core Features and Technical Advantages

1. Wide Temperature Range and High-Precision Temperature Control

The operating temperature range typically spans from room temperature up to 300°C, with an advanced PID intelligent temperature-control system that keeps temperature fluctuations within ±0.5°C. It supports programmable heating curves and multi-stage holding‑temperature control, making it suitable for complex process requirements.



2. Fully enclosed circulation design, safe and efficient

The system features a fully enclosed design, reducing the oxidation and volatilization of heat-transfer oil at high temperatures and extending the service life of the working fluid. It is equipped with multiple safety devices, including an expansion tank, a pressure relief valve, and over-temperature protection, ensuring stable and reliable operation over long periods.



3. Efficient circulation and rapid response

Equipped with a high-flow, high-temperature-resistant circulation pump to ensure uniform heat distribution and prevent localized overheating. Some models support variable-frequency control, allowing flow and pressure to be adjusted as needed.



4. Intelligent Operation and Remote Monitoring

Features an LED dual-display screen that shows the set temperature and the actual temperature in real time; supports touch buttons or PLC control, and some units are equipped with an RS485 communication interface for connection to a host computer, enabling remote monitoring and data logging.



Typical Application Scenarios

Chemical and Pharmaceutical Industries: Used for jacket temperature control in reaction vessels, pilot-scale scale-up, distillation and purification, and other processes.

New Materials Research: Provides a stable heat source in the synthesis of carbon fibers, semiconductors, and lithium-ion battery materials.
