Configuration and technical description of each system:

Box structure:

1) This equipment is composed of chamber, heating system, electrical control system, air supply system, nitrogen filling system, protection system, etc.
2) The cabinet adopts equipment production, process manufacturing process, smooth lines, and beautiful and generous.
3) The material of the studio is stainless steel, the outer box material is cold-rolled steel plate, and the product shell is sprayed with metallic paint, and the overall design is beautiful and elegant, which is suitable for the color matching of the laboratory.
4) The height and number of shelves can be adjusted according to the user’s requirements.
5) The insulation material between the studio and the outer box is ultra-fine glass fiber insulation cotton, the thickness of the insulation layer: >70mm, thermal insulation, insulation structure. From the inside to the outside, there are inner cavities, inner shells, ultra-fine glass fibers, aluminum reflective aluminum foil sheets, air interlayers, and less heat loss in the inner tank. The unique structure of the inner tank box and door liner greatly reduces the heat transmission of the inner chamber.
6) The sealing material and rubber sealing structure are used between the door and the door frame, which are sealed, high-temperature and anti-aging.
7) The air duct in the box adopts a dual circulation system, stainless steel multi-wing centrifugal air turbine and circulation air duct, and the heat of the electric heater placed on the back of the box is discharged forward through the side air duct, and then sucked in by the centrifugal air wheel on the back after drying the matter, forming a reasonable air duct, which can fully convection the hot air and make the temperature in the box reach uniformity. The ability to heat the air flow is improved, and the temperature uniformity of the drying oven is greatly improved.
8) Stainless steel electric heating tube for heater, fast heating up
9) The equipment is equipped with imported nitrogen flow meter, and equipped with quick plug-in and unplugged nitrogen filling interface, which is convenient for filling nitrogen and controlling nitrogen flow.

Temperature measurement and control system:

Using the “HM” brand digital display temperature controller imported from South Korea, the product adopts comprehensive electromagnetic compatibility design and humanized menu design, so that the equipment operation is completely foolish and temperature controlled. The dual-screen high-brightness wide-window digital display is clear and intuitive. Microcomputer intelligent control, after setting the temperature, the instrument controls the heating power by itself and displays the heating status, and the temperature control is accurate and stable. Over-temperature alarm and automatically cut off the heating power supply. There is a timer function, and the timer time is up to 9999 minutes.

Electrical Control System:

1) The electrical control components are all “Chint”
2) The electrical circuit design is novel, reasonable wiring, safe and reliable
3) The top of the box is an electrical control cabinet, which is convenient for centralized inspection and maintenance

Safety protection system:

1) Over-temperature alarm
2) Fast fuse

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

1) Programmable LCD controller, which can realize adjustable heating rate and holding time, 18 segments can be programmed.
2) Independent temperature limiting controller, which can realize the immediate cutting off of heating when the equipment temperature rises too high after the main controller fails.
3) Paperless recorder, through USB interface to import its recorded data into the computer for analysis, printing, etc., is an updated product of paper-based recorder, eight-channel temperature recording.
4) Equipped with RS-485 interface, it can be connected to computers and recorders to realize real-time monitoring of working status.
5) Temperature test hole, can realize different test lines or instruments inserted into the equipment working room for various tests, the test hole hole diameter is ¢25, ¢50, ¢80 optional.
6) Cargo brackets, the standard configuration of the equipment is 2 cargo brackets, customers can increase the number of brackets according to specific requirements.
