the glycol refrigeration heating system uses a fully enclosed circulation system, which avoids the opportunity for the antifreeze to contact the outside air and ensures no condensation. after the expansion tank is protected by nitrogen, the temperature range of the heat-conducting liquid is also broadened because its boiling point is increased. In addition, oxidation of the thermally conductive liquid in contact with oxygen in the environment is also avoided, thus extending the useful life of the thermally conductive liquid.

Accurate temperature control is especially important for the repeatability and accuracy of test results. the system uses Siemens PLC control. the electrical control section does not require human intervention to complete all control. Because of this high level of automation, there is very little manpower required to withstand testing.

Provides high operational safety. Newly added security measures ensure continuous unattended operation. All relevant operational status data is continuously monitored and visualized on the touch screen.

the Siemens 7" color large screen provides clear and comprehensive data information with important information such as data, graphics and notes. the touch interface optimizes the usability of the device. Multi-level users can be protected by password protection. Personnel have limited privileges and can only accept settings. this avoids accidental modification and misoperation of parameters. the operation is continuously monitored. Warnings and faults are clearly displayed and the system automatically shuts down if necessary. Tracking, so the test does not need to be started. At this point, the existing records will be called. the system has a variety of data and communication channels, which can be adjusted according to the specific application. the temperature control unit can also be remotely controlled or It is contained in a control system.
