箱体结构特点： First, the structural characteristics of the box:
1. The box body is processed by CNC machine tools, with beautiful appearance and easy operation.
2. The inner tank of the box adopts imported high-grade stainless steel (SUS304) mirror panel, and the outer tank of the box is sprayed with A3 steel plate, which increases the appearance and cleanliness.
3. Large-area windows with illuminators keep the inside of the box bright, and the built-in three-layer tempered glass inside the heating body can clearly observe the conditions inside the box.
4. The left side of the cabinet is equipped with a test hole with a diameter of 50mm as standard, which can be used for external test power lines or signal lines.
、具有防爆功能。 5 , with explosion-proof function.
Equipped with a balanced constant temperature control system (BTHC), LCD LCD PID + SSR microcomputer integrated controller, stable performance, high accuracy and simple operation.
3. Refrigeration and air circulation system:
1. The refrigeration unit adopts "Taikang" air-cooled hermetic compressor imported from France.
2. The refrigerant uses environmentally friendly green (HFC) R404a, and has zero pollution.
3. The centrifugal blower is used for strong circulation to avoid any dead angles, which can make the temperature distribution in the test area uniform.
4. The heating and cooling systems are completely independent, which can improve efficiency and reduce failure rate.
5. Refrigeration auxiliary parts: Expansion valve (Danfoss DANFOSS), solenoid valve (Italy), filter (Danfoss DANFOSS), pressure switch (Danfoss DANFOSS), gas-liquid separator (European and American ALCO) and other imported refrigeration accessories
4. Safety protection device:
1. Studio over-temperature independent protector
2.Heating overload protector
3.Compressor overheating protection switch
4.Compressor high voltage protection switch
5.Compressor overcurrent protection switch
6, leakage short circuit protection switch
7.Circular motor overload and overheat protection switch
