with the progress of society, industrial development is also developing rapidly. Therefore, refrigeration circulators have attracted the attention of many companies.

Nowadays, many chemical plants and laboratory research institutes have great demand for this, and they can be heated and cooled. Its maximum temperature range can reach: - 25 ~ 200 degrees, to ensure immediate cooling under high temperature conditions, can achieve continuous temperature control of 200 ~ 25 degrees.

Compared to other companies, our refrigeration circulators have a wide operating temperature range because our refrigeration equipment is a closed system. It does not absorb moisture at low temperatures. It does not produce oil mist at high temperatures. The heat transfer oil can be adapted to a wide operating temperature range. The solenoid valve is not used throughout the circulatory system. The circulation management is completely sealed, without oil mist and water absorption, ensuring the safety and thermal life of the experiment. It also has a variety of security features.
