Yihexing vacuum nitrogen gas cabinet, also known as vacuum storage cabinet, is used for electronic products (semiconductors, circuit boards, electronic products, chips, battery boards, battery cells, electronic components, advanced metal products, anaerobic products, easily oxidizable products, etc.)）Stored in a vacuum environment, it has functions such as preventing oxidation, discoloration, browning, moisture, and extending product storage life.

1. The equipment is equipped with multiple independently controlled high vacuum enclosures, which create an anaerobic environment through vacuum pumping and nitrogen filling, for storing easily oxidizable products.
2. The equipment mainly consists of a vacuum box, a vacuum pumping system, and a nitrogen filling system. Each chamber is independently controlled, and oxygen reduction is carried out by first vacuuming and then nitrogen filling. Vacuum pumping and nitrogen filling actions can be programmed or manually set. The control system can display and record the oxygen content and vacuum degree, and support data export.
3. The time between each cabinet is completely independently timed and controlled, using a sealed chamber and not using high flow nitrogen filling to maintain the mold mode.
4. The vacuum system adopts oil-free dry pumps, suitable for clean and dust-free workshops. The vacuum pump and pump body are designed in an integrated manner, and well-known brands are selected.

Key parameters:

(1) Vacuum box size: W30cm * D30cm * H30cm or customized according to needs, the number of chambers can be selected according to needs;
(2) Internally welded with 2.0mm 304 stainless steel, and externally treated with cold-rolled steel plate spray coating;
(3) Automatic cycle nitrogen filling system, oxygen content control, ≤ 100ppm;
(4) Achieve the target oxygen content within 6 minutes;
(5) Oxygen content ≤ 100ppm after atmospheric pressure;
(6) Oxygen detector, measurement error 1% FS, accuracy ± 1ppm;
(7) Install a pre precision filter for nitrogen, with a filtration accuracy of 1um;
(8) Vacuum range 10pa-100pa;
(9) Dry vacuum pump, suitable for dust-free workshops, brand optional, can reach up to 100pa within 3 minutes;
(10) Vacuum leakage ≤ 5000pa (24h, vacuum degree 100pa);
(11) Protection measures: The equipment has reliable anti leakage safety protection measures and complete oxygen concentration failure protection measures; The device displays and records the oxygen concentration and vacuum degree of each chamber in real time, and can query historical data and export vertical data.
