Product overview
Flexible treatment space, configured around the collection.
The Sinoalta Flexible Anoxic Treatment Enclosure creates a sealed, low-oxygen environment for non-chemical insect pest treatment. Unlike a fixed chamber, it can be sized around oversized, irregular or difficult-to-move museum objects.
It is intended for temporary or project-based treatment close to the collection, reducing unnecessary handling and transport.
Treatment workflow
How nitrogen anoxia treatment works
Configure
Size and assemble the gas-tight enclosure around the assessed collection or treatment batch.
Replace the atmosphere
Extract or displace air while introducing nitrogen through the selected supply arrangement.
Monitor
Track oxygen, temperature and relative humidity throughout the defined treatment cycle.
Re-aerate
Return the enclosure to normal atmospheric conditions before releasing the collection.
Treatment duration and acceptance conditions depend on pest species and life stage, residual oxygen, temperature, relative humidity, enclosure tightness and collection characteristics.
System configuration
Configure the enclosure and supporting equipment together.
Enclosure & connections
- Flexible gas-tight treatment enclosure
- Nitrogen inlet and gas outlet connections
- Air extraction or evacuation equipment
- Sealing accessories
Monitoring & control
- Oxygen analyzer and sensor
- Temperature and relative-humidity monitoring
- Pressure or gas-flow monitoring where required
- Optional treatment recording and humidity conditioning
Final configuration is selected according to treatment volume, collection type, site conditions, nitrogen source and monitoring requirements.
Selection comparison
Flexible enclosure or fixed chamber?
| Decision factor | Flexible enclosure | Fixed chamber |
|---|---|---|
| Installation | Temporary and portable | Permanent or semi-permanent |
| Treatment volume | Configured for the project | Defined by chamber dimensions |
| Object format | Well suited to oversized or irregular objects | Limited by chamber access and volume |
| Typical use | Variable, on-site or temporary treatment | Frequent, standardized treatment cycles |
Where it fits
A flexible treatment component within museum IPM.
The enclosure supports treatment of assessed books, archives, textiles, wooden objects, furniture and mixed museum collections. It can connect to a nitrogen generator or another suitable nitrogen source and should be used within a wider programme of identification, quarantine, monitoring and post-treatment review.
FAQ
Common questions
What is a flexible anoxic treatment enclosure?
It is a sealed treatment space configured around museum objects or collection batches. Nitrogen reduces the oxygen concentration to create a monitored, low-oxygen environment for insect pest treatment.
How is it different from a fixed anoxic chamber?
A fixed chamber has a predetermined volume and permanent structure. A flexible enclosure adapts to changing object dimensions and is particularly useful for oversized, irregular or temporary on-site treatments.
What collections can be treated?
Potential applications include assessed books, archives, textiles, wooden objects, furniture and mixed museum collections. Suitability must follow the material, condition and conservation requirements of the complete object.
How long does treatment take?
There is no universal duration. The treatment protocol depends on the pest species and life stage, oxygen concentration, temperature, relative humidity, enclosure tightness and collection characteristics.
Can the enclosure connect to a nitrogen generator?
Yes. It can be configured for an appropriate nitrogen generator, cylinder supply or other suitable nitrogen source according to treatment volume and site requirements.
Is nitrogen anoxia suitable for every museum object?
Not automatically. A conservator should assess sensitive or unusual collections and define the treatment protocol before the treatment begins.
