Product overview:

1. It has wide temperature control range, which can meet the needs of users.

2. With a unique balanced temperature control method, with stable and balanced heating capacity, high precision and high stable temperature control can be carried out; The temperature is displayed by touch screen, easy to read, precise and convenient.

3. The temperature error can be adjusted to meet your more accurate test conditions.

4. It has the function of automatically selecting the running refrigeration circuit with the setting of temperature, and the operation is simple.

5. with functions of high temperature on, can be in when the temperature in the oven to 100 ℃, can open the refrigerator, facilitate continuous round-trip experiment was carried out between the high temperature and low temperature.

6. Self-diagnosis function, overload protection of refrigerator, high pressure switch, overload relay, thermal protection device, etc., to ensure the safety of use.

7. Use the multi-wing fan to supply the wind with strong air circulation and avoid any dead Angle, so that the temperature can be evenly distributed in the test area.

8. Wind circulation is designed with wind return wind. The wind pressure and wind speed are in accordance with the test standard.

9. Temperature rise, cooling and system complete independence can improve efficiency, reduce test cost, increase life span and reduce failure rate.

10. The water tank is placed in the lower right part of the control box, and there is water shortage and automatic protection, which facilitates the operator to replenish the water supply.

11. The humidification system pipeline is separated from the control circuit board, which can avoid the failure of water leakage in the humidified pipeline and improve the safety.

12. The piping system of the waterway system is opened by door to facilitate maintenance and repair.

13. In refrigeration system, air cooling or water cooling is adopted in condensation.

14. The test unit needs to undergo a specific temperature change curve and record the change of temperature.The range of temperature varies from -40 to 100 degrees.

15. When conducting tolerance tests, it is usually carried out in an infinite loop.

16. The temperature of the antifreeze is from -45 to 100 degrees.

17. Very steep temperature gradient changes.

18. Visualization, data storage and reporting analysis.

19. The temperature control device can be flexibly connected with other test platforms.

20. Equipped with a strong circulating pump, while ensuring the delivery of high viscosity liquids.

21. Adopt proportional control valve to control the flow output, and achieve a high precision control of 10% ~ 100% of the total range.

22. The ethylene glycol refrigeration heating system USES a fully closed circulation system, thus avoiding the opportunity of the antifreeze and outside air contact to ensure that there is no condensation of water vapor.After the expansion tank is protected by nitrogen, the temperature range of the conductive liquid will also be widened because its boiling point has been promoted.In addition, the oxidation of oxygen in the heat conducting liquid and the environment is also avoided, thus extending the service life of the thermal conductivity liquid.

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

24. High operational security is provided.The newly added security measures ensure a continuous unattended operation.All relevant running state data is continuously monitored and visualized on the touch screen.

The large color screen of Siemens 7 provides clear and comprehensive data information, which contains important information such as data, chart lines and annotations.The touch interface optimizes the availability of the device.Multi-level users can be implemented through password protection.The specified operator has limited permissions and can only accept Settings.This avoids accidental modification and misoperation of parameters.The operation is continuously monitored.Warnings and failures are clearly displayed and the system shuts down automatically when necessary.Faults can be tracked, so testing doesn't have to be done from scratch.At this point, the existing records are called.The system has a variety of data and communication channels, which can be adjusted according to specific applications.The temperature control unit can also be remotely controlled via the network or contained in a control system.

What are the chiller's precautions for purchasing an environmental laboratory?

The water cooler is also called a chiller and is a kind of cooling water equipment that can provide constant temperature, constant current and constant pressure. At present, there are many kinds of water cooling machines in the market, and the quality is uneven. The prices are different. How do you choose the right water cooler for your environmental laboratory?

Market rules determine that all product prices are cost plus profit, and water coolers cannot be an exception. If the selling price is too low, manufacturers will certainly make a fuss about the cost of water-cooled machines. So buying a water cooler can examine the quality of the product from the following aspects:

1. Compressor: The compressor’s cost alone accounts for a large part of the cost of the water cooler, and it is the core component of the water cooler, which determines the cooling capacity of the water cooler. It is usually judged from the four aspects of brand, stability, energy consumption and service life whether the water cooler is good and reliable.

2. Condenser: It is generally made of copper tube, and the refrigerant is carried in the tube, and the aluminum fin is matched to obtain a large surface area for heat exchange. The quality of the condenser can usually be considered in terms of materials, condensation area, and material quality.

3. components: including contactors, relays, thermal protectors, expansion valves, pressure controllers, dry filters, etc. It is these components that ensure the normal operation of the water cooler. The seemingly unimportant component quality determines the reliability of the water cooler. In general, the quality of the components of the big brands is stable and reliable. Therefore, according to the brands selected by the components of the water-cooled engine manufacturers, the product quality can be roughly judged. Guanya Refrigeration is good!
