Low Temperature Circulator -50~30℃
主要用于需要超低温循环冷却液体的低温反应釜夹套，适用于维持低温工作条件的反应；can be paired with 20L, 50L, 100L double glass reaction vessels to cool the contents inside.
Applicable to environmental tests in aerospace and aviation, heat sink tests, low-temperature reactors in the chemical industry, purification of special gases, and equipment such as low-temperature distillation, rectification, and extraction in the chemical industry.
Features include self-diagnosis; overload protection for the refrigerator; high-pressure pressure switch, overload relay, thermal protection device, low liquid level protection, high-temperature protection, sensor failure protection, and a variety of safety functions.
The entire system is fully enclosed, with no oil mist at high temperatures and no absorption of air moisture at low temperatures. The system does not increase pressure due to high temperatures during operation, and automatically supplements the heat-conducting medium at low temperatures.
