Product Overview
The constant-temperature bath employs an internationally advanced new refrigeration system, ensuring stable and reliable performance. It features both internal and external circulation: the internal circulation can directly conduct constant-temperature tests on samples or products, while the external circulation uses a high-pressure pump to circulate the constant-temperature medium, enhancing temperature uniformity, reducing fluctuations, and providing reusable constant-temperature cooling fluid for testing experiments or production. This instrument is widely used in research departments, universities, and enterprises in fields such as petroleum, chemical engineering, and electronic instrumentation. It offers a controlled heating or cooling liquid environment and can be used for direct heating, cooling, or as an auxiliary cooling source.
Product Features

2. ABS-molded control section and streamlined appearance, combined with R-rounded edge design, ensuring safety and aesthetics.
3. High-performance stirring circulation motor, featuring low noise, low heat generation, fully enclosed design, and long service life; equipped with a heatless circulation pump.
4. 304 stainless steel tabletop and inner tank, with additional positioning and surface treatment for the cooling coil.
5. Fully enclosed motor impeller, with low-liquid-level dry-run protection and alarm functions.
6. Power-off protection and over-temperature alarm, ensuring multiple safety protections.
7. Fully enclosed compressor unit for cooling, with overheat and overcurrent protection.
8. Four-sided door panels that can be flexibly assembled and disassembled for easy dust cleaning.
9. Equipped with temperature calibration and auto-tuning functions.
10. Circulation ports and drainage outlets use 304 stainless steel barbed connectors, with a built-in concealed drainage valve.
11. Comes with two sections of silicone hose with thermal insulation sleeves as standard.
Working Principle
The constant temperature medium inside the tank is led out through an insulated hose at the water outlet to establish external constant temperature, providing a constant-temperature coolant for testing experiments or production. The liquid environment temperature is uniform and stable, and the constant-temperature coolant can be recycled and reused. The internal circulation allows direct constant-temperature testing of test samples or products inside the tank, while the external circulation uses a high-pressure pump to cycle the liquid medium in the tank for constant temperature, enhancing temperature uniformity within the tank and reducing temperature fluctuations.
Application Areas
Research departments in petroleum, chemical engineering, electronic instrumentation, physics, chemistry, bioengineering, health, life sciences, light industry and food, physical property testing, and chemical analysis, as well as higher education institutions, enterprise quality inspection, and production departments.
Operation steps
1. Connect to the power supply and turn on the device.
2. Set the required temperature via the large backlit LCD screen.
3. Independently start or stop heating, cooling, and internal/external circulation functions as needed.
4. When connecting external equipment, use the circulation ports and drain outlet to route the constant temperature medium through insulated flexible hoses.
5. Use the two included sections of circulation silicone tubing and insulation sleeves for flexible connections.
6. Monitor the actual temperature, and use the temperature calibration and self-tuning functions for adjustments when necessary.
7. After the experiment, turn off all functions and disconnect the power supply.
Precautions
- Avoid dry heating of the heating tube at low liquid level to prevent damage.
- Ensure timely response to light and sound alarms.
- In case of over-temperature or power failure, inspect and eliminate faults before reuse.
- Regularly remove the surrounding panels to clean dust and maintain cooling efficiency.
- During operation, ensure the circulation and drain connections are secure to prevent leakage.
- Avoid damaging the built-in concealed drain valve during handling.
- Before use, confirm that the power supply and cooling system are normal to avoid overload.
- The instrument should be placed in a stable and well-ventilated location to prevent overheating.
- Operators should understand and comply with safety protection requirements, such as the fully enclosed design of the motor impeller.
- After prolonged operation, check the cooling system for overheating or overcurrent conditions.
