3、 Box structure
1. The inner liner of the high and low temperature test chamber is made of imported (SUS304) high-quality mirror stainless steel plate;
2. Insulation material: high-density glass fiber cotton The insulation thickness is 80mm;
3. Using non reactive door handles makes operation easier;
4. The bottom of the machine adopts high-quality fixed PU movable wheels;
5. The outer shell is made of high-quality (t=1.2mm) A3 steel plate CNC machine tool, and the surface of the shell is sprayed with plastic for a smoother and more beautiful appearance;
6. Mixing system: using a long axis fan motor and a stainless steel multi blade impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation;
7. Double layer high tensile sealing strips with high temperature resistance are used between the door and the box to ensure the sealing of the testing area;
8. The observation window is made of multi-layer insulated tempered glass, with a laminated conductive film on the inner side (allowing for clear observation of the test process);
9. Test holes (on the left side of the machine) are 50mm each (imported original) and can be used for external testing power or signal lines (the aperture or number of holes needs to be increased and indicated).
4、 Control system
Imported digital touch buttons, P.I.D microcomputer S.S.R temperature controller (Japanese RKC instrument);
The main components of the electrical control are all imported (Schneider) components, which better control the temperature
Adopting far-infrared nickel chromium alloy high-speed heating (2KW × 1) electric heater;
Compressor: Fully enclosed French Taikang brand
Refrigeration method: cascade compression refrigeration
The insulation system uses ultra-fine glass fiber to fill the insulation area, and non-metallic high and low temperature resistant materials are used at the connection between the inner and outer bile ducts, effectively reducing temperature conduction
The sealing of the box door is made of refined silicone rubber, so that there is no aging or hardening phenomenon at high and low temperatures
Refrigeration system overload, refrigeration system overpressure
Other protections include leakage, operation indication, automatic shutdown after fault alarm, etc
