System configuration and technical description:

Box structure:

9) The oven is composed of chamber, heating system, electric control system, air supply system and protection system.

10) The box body is made of equipment and process, with smooth lines and beautiful appearance.

11) The studio is made of stainless steel, and the outer box is made of cold steel plate. The outer shell of the product is sprayed with environmental friendly metallic paint. The overall design is beautiful and generous, which is suitable for the color matching of high-end laboratories.

12) The shelf height and the number of shelves can be adjusted according to the user's requirements.

13) The insulation material between the working room and the outer box is ultra-fine glass fiber insulation cotton, the thickness of the insulation layer is more than 70mm, the insulation effect is good, and the insulation structure is good. From the inside to the outside, there are inner cavity, inner shell, ultra-fine glass fiber, aluminum reflective foil, air interlayer, inner outer box and door bladder. The unique structure reduces the heat transfer from the inner cavity to the outside.

14) the door and door frames are sealed with a unique rubber seal structure, sealed, high temperature resistant and anti-aging.

15) The air duct in the box is composed of circulation system, stainless steel multi wing centrifugal fan and circulation air duct. The electric heater on the back of the box is discharged forward through the side air duct. After drying, it is sucked in by the centrifugal fan on the back to form a reasonable air duct, which can make the hot air convection fully, make the temperature in the box uniform, improve the heating capacity of air flow, and greatly improve the efficiency Good temperature uniformity of drying oven.

16) The heater is made of stainless steel electric heating tube, which has the advantages of fast temperature rising and long service life.

Temperature measurement and control system

The digital display temperature controller of "HM" brand imported from South Korea is adopted. The product adopts comprehensive electromagnetic compatibility design and humanized menu design, which makes the operation of the equipment completely stupid and has good temperature control effect. Double screen high brightness and wide window digital display, clear and intuitive value. Microcomputer intelligent control, after setting the temperature, the instrument automatically controls the heating power and displays the heating state, the temperature control accuracy is stable. Super high alarm and automatically cut off the heating power. With timing function, the timing time is up to 9999 minutes.

Electrical control system:

4) Electrical control components are brand "Chint".

5) The electric circuit design is novel, reasonable wiring, safe and reliable.

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

Safety protection system:

5) Over temperature alarm

6) Over current protection

7) Fast fuse

8) Grounding protection

Optional parts (additional charge, please pay attention when ordering)

7) Programmable liquid crystal controller can realize adjustable heating rate and holding time.

8) The independent temperature limiting controller can cut off the heating immediately when the temperature of the equipment is too high after the main controller fails.

9) Paperless recorder, through the USB interface to import the recorded data into the computer for analysis, printing, etc., is an updated product of paperless recorder, eight channel temperature record.

10) Equipped with RS-485 interface, it can connect computer and recorder to realize real-time monitoring of working state.

11) The temperature test hole can be used to insert different test lines or instruments into the equipment studio for various tests. The test hole diameters are Φ 25, Φ 50 and Φ 80.

12) Carrier bracket, oven equipment standard configuration 2 carrier brackets, customers can increase the number of brackets according to specific requirements
