A constant temperature bath, as the name suggests, is a bath that can provide a constant temperature. It can be divided into constant temperature air (usually referred to as a constant temperature chamber) and constant temperature liquid (usually referred to as a constant temperature bath). They are generally heated and cooled by a resistance wire and a compressor, supplemented by a PID controller to maintain a relatively standard temperature, in order to achieve experimental purposes.

Working principle and characteristics of a constant temperature bath refrigeration unit：

1) The constant temperature bath chiller unit adopts advanced refrigeration technology and controls the temperature of the constant temperature bath by circulating cooling water. When the temperature inside the constant temperature bath is higher than the set value, the chiller unit begins to work by carrying refrigerant to remove heat from the constant temperature bath, reducing the temperature of the constant temperature bath to the set value.

2) The constant temperature bath chiller unit uses environmentally friendly refrigerants such as R22 or R407C, which have good refrigeration efficiency and environmental performance and are harmless to the environment.

3) A precise temperature control system can be used to set and adjust the temperature as needed. The temperature control range is wide, which can meet different experimental and production needs, and the temperature accuracy can reach up to ± 0.1 ℃.

4) The unit operation is simple and convenient, and users only need to set the required temperature and start switch. At the same time, the unit is also equipped with an intelligent control system that can automatically control temperature and flow, reducing manual intervention; By adopting advanced refrigeration technology and efficient compressors, energy consumption can be effectively reduced. Compared with traditional cooling methods, the constant temperature bath chiller unit has a higher energy efficiency ratio and lower operating costs.

5) Stable and reliable, the chiller unit adopts high-quality materials and strict production processes to ensure stable and reliable performance during long-term operation. At the same time, the unit is also equipped with multiple safety protection measures to ensure the safe use of users.
