SUS304 stainless steel natural ventilation aging box

K-WKL-B SUS304 stainless steelNatural ventilation aging chamber(New model with tempered glass observation windows both inside and outside, totaling3Layer, with lighting)

1、 Working principle

Commonly used for hot air aging testing of rubber products, cable and optical cable insulation and sheath, and other materials. Temperature control adopts digital displayPIDThe automatic temperature controller can set the working temperature arbitrarily and automatically maintain a constant temperature, allowing for natural convection of hot air and promoting rapid aging of the sample under constant temperature conditions. The host structure, instruments, and materials were designed after detailed research on the airflow and temperature inside the box, and have the advantages of sensitive temperature control, good temperature uniformity, large effective space, and stable performance. The reference standards for this model are as follows:

7、 Structural characteristics

1The inner box is made of stainless steel plate, which has strong anti rust ability.

2The space between the box and the workspace is filled with ultra-fine glass wool insulation material, which has good insulation function, effectively ensuring stable and accurate temperature inside the box and its impact on the usage environment.

3The inner door of the box is made of tempered glass structure, which allows clear observation of the heated items inside the box.

4The box is designed with a reasonable hot air circulation channel, which makes the temperature distribution inside the box more uniform and the temperature rise faster; And equipped with adjustable air vents to regulate the amount of air entering and leaving the box. The air intake is located below.

5Temperature control is manufactured using intelligent digital technology and has industrial applicationsPIDSelf tuning and four digit dual row digital display function, high temperature control accuracy, strong anti-interference ability, and very convenient operation.

8、 Installation and debugging

1During transportation, be careful not to exert force on the glass or collide with the box.

2After the equipment lands, it should be placed steadily. If the ground is uneven, it should be corrected.

3Please do not use the instrument in places with direct sunlight or high temperature and humidity.

4The equipment should be kept away from electromagnetic interference sources and the grounding wire of the equipment should be effectively grounded.

5When the equipment is operating normally, the placement of the contents inside the box should not affect air circulation to ensure uniform temperature inside the box.

6The power supply isAC 220V 50HZ, must be used16AThe above three core sockets must have reliable grounding wires, and two core sockets must not be used without authorization.

7Do not place the power cord close to the back, and do not let instruments or other objects press on the power cord to avoid damaging it.

8Before powering on the goods, it is necessary to check whether there is a short circuit or open circuit in the circuit. Check if there are any loose fasteners or other issues.
