Introduction of high and low temperature cycle device

1. Application of high and low temperature circulation device

Explosion-proof high and low temperature circulation device is suitable for the temperature rise and temperature control of glass reactor, metal reactor and bioreactor. It is widely used in chemical, biological and physical laboratories. It is a cold and heat source equipment for universities, environmental protection, biochemistry, medical, chemical, scientific research, genetic engineering, polymer engineering and other laboratories.

2. Principle of high and low temperature circulation device

The whole liquid circulation is a closed system. There is no water vapor absorption at low temperature, no oil mist is generated at high temperature, and the temperature can be continuously raised and lowered from -60 to 200 degrees. The fully closed pipeline design and high efficiency plate heat exchanger reduce heat conduction. The liquid demand also provides the system's heat utilization rate to achieve rapid rise and fall temperatures.

3. Operation high and low temperature circulation device:

3.1 temperature display
After power-on, the digital tube on the meter displays the actual temperature of the device, and the lower row of digital tubes displays the set temperature.
3.2 Temperature setting
Press the SET button, the right digit of the lower row of digital tubes (orange) flashes, then press the shift button (R∕S) to adjust the flashing position, press the up or down button to set the desired setting, then press SET to exit can.

4.Oil inspection of high and low temperature cycle device

4.1 The heat transfer oil can be used for a long time within the recommended temperature range.
4.2 In order to maintain the performance of the heat transfer oil for a long time, the heat transfer oil should be tested, and the test can help people understand the operation of the heat transfer oil system.
4.3 The heat transfer oil is used for a long time at high temperature, and its quality will change slowly. Therefore, the system is continuously sampled and analyzed once for the continuous operation of the system at the high temperature of zui. When there is a problem, the analysis result of the heat transfer oil can help you find Reasons and emergency measures that need to be taken.
4.4 Heat transfer oil detection and analysis requires 0.5 liter sample, the sample needs to be representative, which can reflect the operation of the whole system heat transfer oil. After taking out the sample, cool it to room temperature, put it into a clean container, and indicate the name of the factory, the address, the date of sampling, and the heat transfer oil grade. Place the sealed container in the box and send it to the analysis unit.

5.Oil analysis of high and low temperature cycle device

5.1 Viscosity: Viscosity changes generally indicate the degree of contamination, thermal cracking and oxidative degradation of the heat transfer oil within the system. When the change is greater than 15%, it should be taken seriously.
5.2 Flash point: The change of flash point indicates that there is low boiler formation in the system. When the change is greater than 20%, it should be paid attention to.
5.3 Acid value: The change of acid value indicates that the heat transfer oil in the system is polluted or oxidized. When the acid value reaches 0.5, it should be paid attention to.

5.4 Carbon residue: The increase of carbon residue value generally indicates that it is caused by stolen goods, corrosive substances, severe oxidation or severe pyrolysis. When it reaches 1.0 (m%), it should be paid attention to.
