225L high and low temperature alternating test chamber The box body is processed by CNC machine tool, which is beautiful and generous, and adopts non reaction handle, which is easy to operate. The outer box adopts SUS304 fog surface line processing stainless steel plate, inner box using imported stainless steel SUS 304 mirror plate. Insulation material: high density PU foam rubber + glass fiber cotton. Air transport system: adopt long shaft motor, stainless steel multi blade impeller with high and low temperature resistance, to achieve vertical diffusion circulation of intensity convection. The observation window is made of multi-layer hollow toughened glass with high-definition heat conduction film. The left side of the box is equipped with a 50mm test hole, which can be used for external test power line or signal line. The bottom of the machine adopts fixed Pu movable wheel and flat water foot.

9. Refrigeration system: original French "Taikang" brand compressor, air-cooled condenser, oil separation, solenoid valve, drying filter, etc

10. Circulation system: adopt lengthened shaft motor and stainless steel multi wing wind wheel with high and low temperature resistance

225L high and low temperature alternating test chamber Controller:

1. Imported CTM series tinko9fp02 temperature and humidity controller, touch button type, operation mode: fixed value.  

2. The original imported "sp-790" LCD display button type input, temperature programmable controller, with 30 groups of 300 program memory, can repeat 999 cycles.  


225L high and low temperature alternating test chamber Refrigeration and air circulation system:

1. The refrigerator adopts the French original "Taikang" totally closed compressor, and the refrigeration system adopts the design of one or two-dimensional low-temperature circuit system.  

2. The multi wing forced draft fan is used to supply air circularly to avoid any dead angle, so that the temperature distribution in the test area is uniform.  

3. The wind pressure and wind speed meet the test standard, and the temperature can be stabilized quickly when the door is opened.  

It can reduce the temperature rise rate and increase the test cost completely.
