The low-oxygen control insecticidal technology uses clean nitrogen as the insecticidal gas, and reduces the oxygen content in the air-tight insecticidal container to isolate the oxygen source that reunion relies on to achieve the purpose of pest control. Compared with the traditional chemical fumigation and insecticidal method, the low-oxygen control insecticidal system has the characteristics of no chemical residues, no harm to cultural relics, non-toxic and environmental protection.
The low-oxygen control insecticidal system is composed of a low-oxygen gas generating device, an airtight insecticidal container, etc., with optional humidity control and dosing modules as required. Among them, the airtight insecticidal container can be divided into bag type, cabinet type, warehouse type, etc. The system can be equipped with different gas generating devices according to the number of collections processed and the time of killing insects.
This series of products mainly include atmospheric and low oxygen insecticidal system, vacuum hypoxia insecticidal system and portable low oxygen insecticidal system.

3) The insecticidal container has good air tightness, and the gas exchange rate is less than 2%/d, which can maintain the stability of the oxygen content and humidity in the container for a long time;
4) Nitrogen is used as the insecticidal raw material, and there is no chemical residue in the cultural relics after insecticidal, and it does not damage the cultural relics.
2. Vacuum low oxygen insecticidal system
Product name: Vacuum low oxygen insecticidal system
Product description: The method of vacuuming and nitrogen filling can achieve rapid oxygen reduction in the insecticidal space, and the oxygen content in the vacuum cabinet can be reduced to below 0.1%. It has the characteristics of high insecticidal efficiency and high speed, which is lower than normal pressure. For the oxygen insecticidal method, the vacuum low oxygen insecticidal system can shorten the insecticidal time.
Applicable objects: Suitable for nitrogen filling, insecticidal and antibacterial treatment of dense cultural relics such as paper and silk fabrics.
Product composition: Mainly composed of vacuum cabinet (including vacuum pump), nitrogen production unit, air compressor, nitrogen buffer tank, etc.
Product Features:
1) Insecticidal and antibacterial functions;
2) The system has automatic control functions of nitrogen production, vacuuming and nitrogen filling;
3) It can realize the setting, modification, real-time display and control functions of oxygen content, vacuum degree and other parameters;
4) Query, storage and export functions of historical data;
5) Equipment failure alarm function.
Parameter index:
Vacuum cabinet volume: 1, 3, 5m³
Oxygen concentration range: as low as 0.1%
Power supply: AC380V/50Hz;
Power supply: It depends on the volume of the vacuum cabinet and the matching high-purity nitrogen display and control device.
3. Portable hypoxic insecticidal system
Product name: Portable hypoxic insecticidal system
Supporting portable gas pumping and nitrogen filling device model: CKC-50A
Product composition: nitrogen source (cylinder or nitrogen generator), portable nitrogen pumping and filling device, flexible airtight insecticidal bag, etc.
Product description: An external nitrogen source is used, and a portable air-pumping and nitrogen filling device is used to pump and fill the special airtight insecticidal bag with the collection to reduce the oxygen concentration in the insecticidal bag below 0.1%, creating a low Oxygen environment to achieve the purpose of killing insects and bacteria.
Note: This system can also be used for preventive protection and storage of collections.
Applicable objects: It is suitable for the insecticidal and antibacterial treatment of archives, rare books, modern books, textiles, animal skins, animal and plant specimens, bamboo and wood lacquerware and other collections.
Note: In order to avoid mechanical damage to the collection when pumping, it is not advisable to vacuum the insecticidal bag when pumping.
Product Features:
1) The system has the functions of insecticidal, antibacterial and long-term preventive protection and storage of collections;
1) The equipment has functions of pumping and nitrogen filling;
