The safety protection issue must be taken seriously during the use of the constant temperature and humidity test chamber. The safety protection device of the programmable constant temperature and humidity test chamber is particularly important in order to control the potential damage to life, property, and the environment caused by the system's operating status within an acceptable range,
1. Refrigeration system: Leak testing, compressor overheating, and refrigerant leakage from compressor overpressure are not harmful to human health. If the low temperature cannot be lowered, it will affect the progress of testing and delay the progress of testing samples, causing inconvenience to production, especially at low temperatures of -40 degrees. Because R404 and R23 refrigerants are required, R23 refrigerant is only available from professional companies, so maintenance may take some time.
2. Humidification system: Heating tube dry burning, abnormal water supply, water shortage alarm. If the humidification system malfunctions, the wet heat test cannot be carried out. More importantly, there may be heating tube dry burning, and the severity of this consequence is believed to be guessed by everyone. Therefore, a water shortage alarm device cannot be omitted. A water level float ball is installed in the water tank, and when the water level drops below the float ball, an audible and visual alarm will appear until it is manually released or automatically stopped. Another issue is abnormal water supply. This safety protection device can prevent abnormal water supply and drainage in the test chamber, which may cause water disasters in the laboratory.
3. Circuit system: Over temperature protection, fan motor overheating, overall equipment under/reverse phase, overall equipment timing, leakage protection, overload and short circuit protection
All of the above phenomena may cause the machine to ignite, burn out the entire circuit board, or even cause a fire in the laboratory, resulting in major faults. Leakage protection is mainly a protective measure for personal safety, because the constant temperature and humidity test box uses a voltage of 380V, which can easily cause personal injury if touched by people. Therefore, there are three checks when doing over temperature alarm and leakage protection to confirm the safety of the safety device. We use imported spare parts and have undergone repeated testing. In addition to providing a real and reliable natural environment and climate for your test site, we also safeguard your safety.
