High and Low Temperature Circulator

A high and low temperature circulator is a device widely used in laboratories and industrial production to simulate the performance and behavior of substances under various extreme environmental conditions. The device can simulate different environmental conditions such as high temperature, low temperature, humidity, and dryness by controlling parameters such as temperature, humidity, and pressure, so as to test and evaluate materials.

In laboratories and scientific research fields, high and low temperature circulators are widely used in material research, electronic component testing, pharmaceutical research and development, food industry, aerospace and other fields. In material research, high and low temperature circulator can be used to test the temperature resistance, oxidation resistance, mechanical strength and other properties of materials, and to evaluate the long-term use effect of materials. In the testing of electronic components, the high and low temperature circulator can be used to test the temperature resistance, moisture resistance, shock resistance and other properties of electronic components, and to evaluate the reliability of electronic components. In pharmaceutical research and development, high and low temperature circulators can be used to test the stability, degradability, solubility and other properties of drugs, and to evaluate the storage and transportation conditions of drugs. In the food industry, high and low temperature circulators can be used to test the freshness, taste, color and other properties of food, and to evaluate the storage and transportation conditions of food. In the field of aerospace, high and low temperature circulators can be used to test the temperature resistance, oxidation resistance, mechanical strength and other properties of spacecraft, engines, fuels and other materials, and evaluate their use effects in extreme environments.

The basic principle of the high and low temperature circulator is to realize the substance testing under different temperature conditions by controlling the heating and cooling system. Among them, the heating system is heated by electric heating wire or electric heating tube, and the refrigeration system is cooled by refrigerant circulation. At the same time, the high and low temperature circulator is also equipped with auxiliary equipment such as humidity control system, pressure control system and gas flow control system to meet the needs of different test conditions.

There are two main types of high and low temperature circulators that are common in the market at present: one is a water bath circulation device, and the other is a refrigeration type circulation device. The water bath circulation device realizes the test under different temperature conditions by putting the sample into the water and controlling the temperature of the water, and is usually suitable for the test in the low temperature range. Refrigerated cyclers, on the other hand, use a refrigerant and heating system to control the temperature and are generally suitable for testing in the high temperature range.
