have 120 groups of programs, each group of 99 segments, each segment can cycle 999 steps, and the maximum value of each period is 99 hours and 59 minutes;
Yantai high and low temperature impact test box manufacturer circulatory system
The refrigerator is made in France "Taikang" totally enclosed compressor.
The refrigeration system adopts unit or binary low temperature circuit system design.
The multi wing forced draft fan is used to supply air circularly to avoid any dead angle and make the temperature distribution uniform in the test area.
The air pressure and wind speed meet the test standard, and the temperature can be stabilized quickly when the door is opened.
Heating, cooling and system independence can improve efficiency, reduce test cost, increase service life and reduce failure rate.
