What Is Refrigerated Heating Circulator?

Refrigerated Heating Circulator also known as high & low temperature integrated machine, refrigeration heating integrated machine. It provides high and low temperature circulating liquid for equipment that needs to be cooled or heated, such as reactors.
Refrigerated Heating Circulator provides heat or cold sources in accurately control status for reaction vessels through external circulation to achieve the required conditions for the reaction.
Refrigerated Heating Circulator is widely used in organic synthesis, biology, pharmacy, food and other major scientific research and university laboratories.
Refrigerated Heating Circulator feature in safe, efficient, environmentally friendly and convenient.
You can choose explosion-proof types if your working condition is flammable and explosive.
How Does Refrigerated Heating Circulator Work?

Refrigerated Heating Circulator is a temperature control instrument that can perform cooling and heating functions.
The refrigeration and heating circulator mainly uses circulating heating and cold and heat, and the fully closed circulating pipeline reduces the contact area of the heat transfer medium and reduces the loss of heat transfer oil.
Refrigeration and heating circulators generally use heat transfer medium or refrigerant to perform refrigeration and heating cycles in pipeline circulation refrigeration and heating to achieve the temperature target change.
The refrigerating and heating circulator is a fully enclosed circulating line temperature control. It does not need to replace the heat transfer medium at high or low temperature, and can directly cool down at 300 degrees to reach the required temperature.
Why does the Refrigerated Heating Circulator make noise when working?

When the Refrigerated Heating Circulator works under normal conditions, the noise is very small.
You need to check the below reasons if there is big noise.
Excessive Wear of Internal Parts of Refrigerated Heating Circulator
Hydraulic pump valve is one of the parts that are easy to cause noise in the Refrigerated Heating Circulator.
There are servo spools and flow pistons that control the hydraulic pump. If these two are worn, it will cause pressure fluctuations, resulting in greater vibration and noise at the pump outlet.
When the Refrigerated Heating Circulator is working, the valve plate is worn or there are dirty deposits at the opening of the exhaust port will shorten the exhaust port, change the position of the exhaust port, and generate a lot of noise.
The Hydraulic pump of the Refrigerated Heating Circulator Enters the Air
If the liquid pump enters the air, it is easy to form air pockets, which will cause the oil to vibrate during transmission, thereby causing cavitation noise.
If the filter inlet of the hydraulic pump is blocked, and the viscosity of the oil is too high, it is easy to cause the vacuum of the water inlet to be too high.
After the air enters, the pipeline will fail and noise will be generated.
In addition, the oil level cannot be lower than the bottom line, otherwise, the drainage pipe may be emptied, making the high and low temperature integrated machine produce noise.
What are the multiple protection functions of the Refrigerated Heating Circulator?

Refrigerated Heating Circulator is a laboratory equipment with dual functions of heating and cooling.
This equipment is easy to operate, has good heat dissipation, efficient cooling and quiet operation.
Here are the protection functions of refrigerated heating circulator.
High Temperature Cooling
At ultra-high temperature, the compressor can be directly used for refrigeration.
It can be used for exothermic reaction at high temperature such as 200 °C without changing the medium.
You can just use the compressor can control the temperature and take away excess heat.
Wide Temperature Range
A wide range of system temperature control from -120℃ to 300℃ can be achieved with a single heat transfer medium.
Temperature information will be transmitted in real time at the temperature measurement points at the liquid inlet and outlet and the material.
When the temperature difference is large, the control system will immediately issue an exothermic and endothermic reaction to precisely control the temperature of the heat transfer medium within ±0.3°C.
Heating Protection
After the control protection of the controller body fails, the temperature exceeds the temperature value set by the deviation protector in the system, and the power supply of the solid state relay will be cut off.
The independent temperature limiter does its job after the protector fails.
With this triple protection, there will be no high temperature overshoot.
