Circulating heating device

Product Description

1. The entire liquid circulation is airtight, with an expansion vessel. The expansion vessel and the liquid circulation are insulated and do not participate in the liquid circulation. They are only mechanically connected. No matter whether the temperature of the liquid circulation is high or low, the medium in the expansion vessel is lower than 60 degrees.

2. The entire liquid circulation is a closed system, there is no absorption of water vapor at low temperatures, no oil mist is produced at high temperatures, and the heat transfer oil can have a wide operating temperature; no mechanical and electronic valves are used in the entire circulation system.

Features

1. Wide operating temperature range, with heating and cooling functions at the same time, the maximum temperature range: -25℃~200℃.

2. To ensure rapid cooling under high temperature conditions; continuous temperature control from 200 degrees to -20 degrees can be achieved.

3. The circulation management is fully enclosed, and there is no oil mist and water absorption, which ensures the safety of the experiment and the life of the thermal fluid.

4. The refrigeration unit American Copeland compressor and circulating pump have stable performance and reliable quality.

5. With self-diagnosis function; refrigerating machine overload protection; high-pressure pressure switch, overload relay, thermal protection device and other security functions.

6. Control the temperature of the heat-conducting medium, and the same heat-conducting medium is used throughout the temperature rise and fall process.

7. High-lift design, to meet the needs of long-distance transportation of heat transfer media.
