Technical Parameters ^LNE//I-Ethylene glycol cooling&heating temp, control system Application The testing object is connected to a testing adapter. Components cooling and heating test is conducted by ethylene glycol aqueous. The whole component is in the environment storehouse which offers a high or low temp, environment. The testing of components will have a specific temp, variation curve, it will record the temperature change. Temp, range is usually from -40°C to 150°C. Tolerance tests are usually carried out in an infinite loop. Product description The following are demanded parametric variation of continuous periods: The temp, range of ethylene glycol aqueous solution is from -40°C to 150°C. The temp, range of environment room is -50°C to 150°C. Very steep variations in temp, gradient. The outlet temperature limit. Visualization, data storage, report analysis. Temp, control system can flexibly connecte to other testing platforms. Equipped with a gear pump of good heat and pressure resistance which offers a high flow under a steady pressure output. It can quickly reach the needed pressure and control the pressure beyond the preset Meantime, it can ensure the delivery of high-viscous liquid. The pump adopts frequency control to ensure the optimal heat exchange with load (the flow of water ethylene glycol mixture is about 50 L/min). The integrated Siemens converter ensures high accuracy and speed control (from 30 to 100%) of application requirements. The pressure capacity is 6bar. A closed liquid system is adopted to avoid medium contact with air and ensure no water vapor condenses. The medium temp, range will be wider after the expansion tank have Nitrogen protection because the boiling point of it rises. Meanwhile, the chance for the medium to contact with air is avoided to prolong the lifetime of the medium. Accurate temp, control is especially important for the repeatability and accuracy of the test results. The system adopts s7-200 Siemens PLC. The electrical control section basically does not require human intervention. Because of the high automation, there is very little manpower required for endurance testing. Thermostat can work reliably from 5 to 40°C in the industrial process. In hot summer can use max. 30°C cooling water to cool down. The safety protection IP54 satisfies the safety requirements and means that the machine can be used in a hash environment. Every component can be easy to touch and maintain. High operational security is provided. The newly added safely measures ensure continuous unattended operation. All relevant running data is continuously monitored and visualized on the touch screen. The SIEMENS 7-inch color touch screen provides clear, comprehensive data hat contains important info, such as graphics, lines, and annotations. WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD. The touch interface optimizes the availability of the device. Multilevel users can be protected through password. The admin, can set every day's work. The designated operator has limited permissions and only to accept the settings. This can avoid accidental modification and error handling of parameters. The operation is continuous monitored. Warnings and failures are clearly displayed and the system is automatically shut down when necessary. Failures can be tracked, so testing no need to start again. Then, the existed records can be checked. The system with multiple data and communication channels, which can be adjusted according to application. The temp, control unit can also be controlled remotely by the network or contained within a control system. Machine with standard USB port, LEMO port to connect external temp, sensor and other optional interfaces (Mocks, Modbus RTU RS232/485, Profibus DP, PROFINET). User has the same functionality as the device controller through the network's operating interface.
