What are the temperature control performance of laboratory recirculating chillers

The laboratory recirculating chiller is a typical cooling circulator with heating function to ensure the repeatability of laboratory results. There are water-cooled or air-cooled refrigerators, which can be placed in a laboratory fume hood or set up for internal use.

1. The laboratory recirculation chiller connects each configuration into a closed piping system. There is no inner tank, no solenoid valve, and the heat transfer oil is circulated under the power of the circulating pump to maximize the heating/cooling system. The application that heat or cold is delivered to us---reactor.

2. The fundamental factor in the temperature control of the laboratory recirculating chiller is not heating or cooling, but the most likely transfer of the heat generated by the machine to the application! !

3. The liquid circulation of the whole system is airtight. The system is equipped with an expansion vessel. The expansion vessel and the liquid circulation system are independent 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, but the expansion vessel The medium in is always room temperature.

4. Since the entire liquid cycle is a closed system, there is no absorption of water vapor at low temperatures, and no oil mist is produced at high temperatures. The heat transfer oil can have a wide operating temperature, so the same machine and the same heat transfer medium can achieve temperature control from -120 degrees to 200 degrees.

5. No mechanical and electronic valves are used in the whole system.

6. The heat exchange area of the plate heat exchanger of the laboratory recirculation chiller is very large, so the heat exchange speed is very fast. And at high temperatures, it prevents the heat transfer oil from being locally heated and cracked.

7. Automatically adjust IPD parameters according to the requirements of the process, and automatically adjust the power output to meet the requirements of temperature changes during the reaction process, so as to accurately control the temperature of the reaction process.

8. The controller adopts the touch screen, the operation is very simple, it can display the set temperature of the working process, the jacket temperature, the temperature change curve in the kettle body, and can realize the program heating and cooling, which can be used as needed.

9. A larger temperature difference between the inside and outside of the jacket can be set according to the reliable requirements provided by the glass reactor manufacturer. If the temperature difference between the inside and outside reaches the value required by the manufacturer, the instrument will automatically cut off the power to ensure that the reactor will not be excessive due to the temperature difference. Big and cracked.

10. The pressure of the circulating pump of the laboratory recirculation chiller can be adjusted, so that it can meet the reliable pressure requirements of different reactor jackets and meet the requirements of the reactor.

11. With remote fault diagnosis.
