System configuration and technical specifications:

Box structure:

1) This equipment consists of a chamber, heating system, electrical control system, air supply system, nitrogen filling system, protection system, etc.

2) The box is made of equipment, with a manufacturing process and smooth lines that are aesthetically pleasing.

3) The studio material is stainless steel, the outer box material is cold-rolled steel plate, and the product shell is made of metal paint spraying. The overall design is beautiful and elegant, suitable for color matching in the laboratory.

4) The shelves in the studio can be adjusted in height and quantity according to the user's requirements.

5) The insulation material between the studio and the outer box is ultra-fine glass fiber insulation cotton, with a thickness of insulation layer greater than 70mm and a thermal insulation structure. There is an inner cavity, inner shell, ultra-fine glass fiber, aluminum reflective aluminum foil, and air interlayer from inside to outside, with less heat loss in the inner cavity. The unique structure of the inner and outer compartments, as well as the door liner, greatly reduces the transfer of heat from the inner cavity.

6) The sealing material and rubber sealing structure are used between the door and the door frame, which are sealed, high temperature resistant and anti-aging.

7) The air duct inside the box adopts a dual circulation system, consisting of a stainless steel multi wing centrifugal fan and a circulating air duct. The heat of the electric heater placed at the back of the box is discharged forward through the side air duct, and then sucked in by the centrifugal fan at the back after passing through the dry material, forming a reasonable air duct that can fully circulate the hot air and achieve uniform temperature inside the box. Improved the ability of air flow heating and significantly improved the temperature uniformity of the drying oven.

8) The heater uses stainless steel electric heating tube, which heats up quickly.
9) The equipment is equipped with an imported nitrogen flow meter and a quick plug and play nitrogen filling interface, which facilitates nitrogen filling and control of nitrogen flow rate.

Temperature measurement and control system:

Imported from South KoreaHM brand digital displaytemperature controller，The product adopts a comprehensive electromagnetic compatibility design and a user-friendly menu design, making device operation completely foolproof and temperature controlled. Dual screen high brightness wide window digital display, clear and intuitive indication. Microcomputer intelligent control, after setting the temperature, the instrument automatically controls the heating power and displays the heating status, with precise and stable temperature control. Overtemperature alarm and automatic cut-off of heating power supply. There is a timing function, and the timing time is as long as possible9999 minutes.

Electrical control system:

1) All electrical control components are made of“chint”

2) Innovative electrical circuit design, reasonable wiring, safe and reliable

3) The top of the box is an electrical control cabinet, which is convenient for centralized inspection and maintenance

Security protection system:

1) Overtemperature alarm

2) Quick fuse

Optional accessories (additional charges apply, please note when ordering):

1)Programmable LCD controller,It can achieve adjustable heating rate and insulation time,18 segments programmable.

2)Independent temperature limiting controller,It can be achieved to immediately cut off heating when the equipment temperature rises too high after the main controller fails.

3)Paperless recorder,pass throughThe USB interface imports its recorded data into the computer for analysis, printing, etc. It is an updated product of the paper recorder, with eight channel temperature recording.

4)join in marriageRS-485 interface,Can connect computers and recorders to achieve real-time monitoring of work status.

5)Temperature testing hole,It is possible to insert different testing lines or instruments into the equipment studio for various experiments, with testing hole diameters of ￠25, ￠ 50, ￠ 80 are optional.

6)Load carrier,The standard equipment configuration is2 cargo racks, customers can add additional racks according to specific requirements.
