Vacuum nitrogen filled insecticide cabinet

Principle of vacuum nitrogen filled insecticide cabinet:

The vacuum nitrogen filled insecticide cabinet uses a vacuum pump to evacuate the air inside the cabinet, creating a vacuum state, and then fills it with nitrogen gas to reduce the oxygen concentration inside the cabinet, causing pests to suffocate and die. At the same time, nitrogen can also play a role in preventing moisture, corrosion, and mold. So this article will specifically introduce the functions, parameters, and equipment precautions of the vacuum nitrogen filled insecticide cabinet.

Characteristics: Adopting pure physical method, it uses vacuum filling with nitrogen to isolate oxygen, reduce pressure, evaporate, kill insects, sterilize, and disinfect without adding any chemicals or emitting any harmful gases or pollutants.

Function of vacuum nitrogen filled insecticide cabinet:

Insecticidal function:The vacuum nitrogen filled insecticide cabinet can effectively kill various pests such as mice, cockroaches, ants, mosquitoes, etc.

Moisture proof function:The vacuum nitrogen filled insecticide cabinet can effectively prevent items from getting damp, keep items dry and clean.

Anti corrosion function:The vacuum nitrogen filled insecticide cabinet can effectively prevent items from being corroded and keep them intact.

Anti mold function:The vacuum nitrogen filled insecticide cabinet can effectively prevent items from being damaged by mold, maintaining the hygiene and health of items.

Oxygen barrier function:Ensure that the oxygen content of the device is ≤ 1 ‰ in working condition. Produce nitrogen gas from the supporting nitrogen generator.

Evaporation function:During the disinfection process, the liquid inside the insect can evaporate, damaging the proteins of the adult, larva, egg, and pupae.

Insect killing function:It can kill 100% of adult insects, larvae, insect eggs, pupae, and spores in the collection.

Sterilization function：It can kill 100% of oxygen consuming bacteria, and block the growth, breeding, and reproduction of anaerobic bacteria and filamentous fungi.

Dust removal function:It can remove 100% of the dust attached to the surface of cultural relics, archives, ancient books, etc.

Odor removal function:It can remove all odors 100%.

Remote control function:The on-site equipment can be operated through the mobile APP software (in any area of the network), and the parameter screen is consistent with the touch screen. Optional

Automatic humidification function:When nitrogen is injected into the disinfection room, it is humidified by an automatic humidifier to ensure that the humidity in the disinfection room is between 35% and 60%, and the humidity value can be set between 0% and 100% by oneself.

Nitrogen generation function:During the disinfection process, 99.99% high-purity nitrogen gas can be produced and injected into the disinfection room.

display function：Oxygen content, vacuum degree, temperature and humidity detection display function.

Disinfection time:The entire disinfection time is between 15 hours and 72 hours.
