Read： 727 Time：9months ago Source：Transform the World with Simplicity

R507 refrigerant is a commonly used mixed refrigerant composed of R125 and R143a. It has the characteristics of low temperature and medium temperature refrigeration, so it has been widely used. When using R507 refrigerant, we need to pay attention to the following matters to ensure safety and effectiveness.
1. Wearing Protective Equipment
Appropriate protective equipment, including goggles, gloves, and protective clothing, must be worn when using R507 refrigerant. This can effectively prevent refrigerant damage to the skin and eyes.

2. Follow the operating procedures
When filling, replacing or handling R507 refrigerant, the operating procedures must be strictly followed to ensure correct operation. Do not operate without authorization to avoid accidents.

3. Prevent leakage
should always pay attention to the leakage of R507 refrigerant and take timely measures to repair it. Once the refrigeration equipment leaks, it will not only affect the cooling effect, but also cause harm to the environment and human body.

4. Avoid mixing
In the process of using R507 refrigerant, do not mix different types of refrigerant. Doing so may lead to the failure of the refrigeration system, and even cause safety accidents.

5. Storage Precautions
R507 refrigerant should be stored properly, away from fire and high temperature environment. During storage, severe vibration and collision shall be prevented to avoid leakage.

6. Regular inspection
Regular inspection of equipment and pipelines using R507 refrigerant, timely detection of problems and repair. This can ensure the normal operation of the refrigeration system and reduce the possibility of accidents.

the correct and safe use of R507 refrigerant plays a vital role in the normal operation of equipment and the safety of the working environment. Only by strictly observing the precautions and regular maintenance can the safe and stable operation of the refrigeration system be ensured.
