Features and advantages of high temperature circulator

Technical Knowledge 2021-06-23 17:06:50
The closed high-temperature circulator adopts electric heating, and the material in the supporting reaction vessel is heated by the heat transfer fluid output by the circulating pump. It is widely used in the reactor assembly device that requires high-temperature conditions in the pharmaceutical, chemical, and petrochemical industries.

The airtight high temperature circulator is widely used in drying, concentrating, distilling, impregnating chemical reagents, impregnating drugs and biological products, and can also be used for constant temperature heating in water baths and other temperature tests. It is used in biology, genetics, viruses, aquatic products, environmental protection, medicine, hygiene, and biochemistry. An essential tool for education and scientific research in laboratories and analysis rooms. The closed high-temperature circulator has a resolution of 0.1°C and adopts a stainless steel inner tank. The appearance is novel and beautiful, and it has excellent corrosion resistance. The measured temperature and the set temperature are digitally displayed. Automatic temperature control, over-temperature sound and light tracking alarm, so that the sample can be reliably protected and temperature controlled. The display resolution of the meter is 0.1°C.

The high and low temperature pump circulator produced by LABOAO has side air inlet and side air exhaust. The corners are rounded to prevent accidental injury. Casters are installed for more convenient movement. The touch button is easy to operate. It is equipped with a lower discharge port for easy discharge. The waste liquid, over-temperature protection and alarm system enhance the safety factor of equipment safety. The fully enclosed pipeline system is basically isolated from the outside oxygen to reduce the oxidation of the heat transfer oil. It is equipped with a unique oil mist cooling function. The heat transfer oil cannot be used at high temperatures. Avoid generating oil mist. Failure to get timely cooling will greatly shorten its service life. With this cooling function, it not only prolongs the service life of the oil, but also reduces the circulation pressure and increases the flow rate.

Equipment technical features and advantages:

The entire liquid circulation is airtight, with an expansion vessel. The expansion vessel and the liquid circulation are insulated and do not participate in the liquid circulation. They are only mechanically connected. No matter whether the temperature of the liquid circulation is high or low, the medium in the expansion vessel is lower than 60 degrees. .

The entire liquid cycle is a closed system, no oil mist is generated at high temperatures, and the heat transfer oil can have a wide operating temperature.


1. Wide working temperature range, maximum temperature range: normal temperature ~ 250℃;

2. The controller with 2 LED displays can display the temperature set value and actual value at the same time;

3. Efficient and fast, easy to fill liquid;

4. The circulation management is fully enclosed, and there is no oil mist and water absorption, which ensures the safety of the experiment and the life of the thermal fluid;

5. With self-diagnosis function; liquid level protection, thermal overload protection device and other security functions;

6. The high-lift design meets the requirements of long-distance transportation of heat transfer media.
