Equipment structure<\/h5>\n
<\/div>\n
The equipment is mainly composed of cabinet, refrigeration system, heating system, air circulation system and control system.
\nThe test box is perfectly designed, processed and formed by CNC machine tools, and adopts a non-reaction handle, which is easy to operate.
\nThe door seal is made of refined silicone rubber, so that there is no aging and hardening phenomenon at high and low temperatures.
\nThe inner liner is imported SUS304 stainless steel plate, and the shell is A3 plate spraying, which is more smooth and beautiful.
\nThe insulation system uses ultra-fine glass fiber or rigid polyurethane foam to fill the insulation area to ensure the temperature inside the cabinet.
\nThe independent heating and cooling system makes the equipment more effective in improving heating, cooling and efficiency.
\nThe refrigeration system is a fully automatic control and safety protection coordination system.
\nThe use of multi-wing type strong air supply circulation avoids any dead angles and can make the temperature distribution in the test area uniform.
\nThe air circulation outlet and return air design, the air pressure and air speed meet the test standards, and can make the temperature reheating time fast at the moment of opening the door.<\/div>\n
<\/div>\n
The temperature control adopts the “TEMI360” intelligent programmable controller imported from South Korea, 3.5 inch “TFT true color touch thin screen Chinese\/English optional menu, program editing: 120 sets of programs can be edited, each set of programs can edit 100 segments, communication interface RS485, the product display is clear and intuitive, the programmable control system is flexible and convenient to operate, the performance is stable, and the work is more efficient.<\/strong><\/div>\n
