Refrigerated Circulators For Laboratory and Industry

Refrigerated Circulators For Laboratory and Industry

Refrigerated Circulators can achieve low-temperature refrigeration at -120 degrees, and are often used in single-fluid freezing experiments. They are not the same equipment as general space refrigeration, cold storage, and refrigerators. So, what are the points to pay attention to when using Refrigerated Circulators? What are the correct usage methods and steps?

How Refrigerated Circulators Work

Refrigerated Circulators transfer pump drives the heat transfer medium (usually water or oil) in the tank with built-in heater to the temperature control equipment, and then returned to the tank by the temperature control equipment. The controller adjusts the temperature of the thermal fluid according to the temperature of the heat flow measured by the temperature sensor or the internal temperature of the temperature control device, thereby adjusting the temperature of the temperature control device.

How to use Refrigerated Circulators and precautions

1. When using it for the first time, first use a universal meter to check whether the power plug connected to the device is normal, whether there is a mutual short circuit or a bad state, if there is no abnormality, it can be used normally;

2. After turning on the power supply, according to the requirements, add the corresponding circulating water, turn on the power switch and the circulating pump switch on the equipment, so that the circulating water starts to run;

3. Set the temperature range of the low-temperature chiller, set the temperature range of high temperature and low temperature, and make observations. If the temperature range is large, continue to adjust the temperature range;

4. The circulating water of Refrigerated Circulators is generally distilled water or the circulating water of the manufacturer. Do not use well water, river water, etc., which will cause blockage of the circulating pipeline. If tap water is used, it is recommended to clean the pipeline every year;

5. Check Refrigerated Circulators’ pipelines, refrigerants, etc. for leaks every six months. You can judge according to the parameters displayed on the pressure gauge. If the data differs greatly from the usual data, you can make a comparison;

6. The refrigeration system of Refrigerated Circulators needs to formulate an annual cleaning plan, including: heat dissipation pipes, condensing parts, cooling water towers, etc., to avoid system blockage and make the refrigeration system more suitable for operation;

7. If the Refrigerated Circulators are not used for a long time, it is recommended to turn off the water pump, compressor, power supply and other circuit switches of the equipment.

Refrigerated Circulators are mainly used to detect and determine the parameters and functions of electronic, electrical and other product materials that undergo changes in cold environments, involving aviation, automobiles, home appliances, electronics, etc.

Refrigerated Circulators generally use PID temperature control technology. Different manufacturers and different models have different temperature accuracy. There are two types of slotting or fully enclosed, and there are two cooling methods: air cooling and water cooling. In order to achieve a better effect of reducing the material temperature, users need Choose carefully.
