Inertia High Speed Doors: Airtight Protection for Oxygen Reduced Areas
Inertia industrial doors, otherwise known as oxygen reduction system doors, are becoming more popular in buildings where valuable goods need to be protected from fire, dust and temperature changes.
At EFAFLEX we are global specialists in high‑speed doors. We design and install bespoke, high‑quality inertia doors that have outstanding airtightness as well as rapid and reliable operation. This article explores what these doors are, their benefits, and ideal use cases.
What Is an Inertia Door & What Are Its Benefits?
An inertia door is a high‑speed industrial door designed for oxygen‑reduced environments. Traditionally, sprinkler systems have been used as a fire protection method, but water can damage stock. Instead, by installing an airtight door, the room and its items are protected by lowering oxygen levels so a fire cannot ignite. To maintain this stable atmosphere, a low air‑permeability high‑speed door is required.
EFAFLEX can use its renowned cleanroom technology with the EFA‑SRT CR Efficient adapted doors and our deep freeze EFA‑SST TK‑100 range as they offer low leakage for ORS applications.
- Air permeability class 5 (DIN EN 12426) – almost hermetic
- Works as part of an oxygen reduction system
- Reduces risk of fire starting – not just extinguishing
- Up to 200,000 operating cycles p.a.
- Works for 24/7 logistics and automated facilities
- Minimises leakage in cold & deep‑freeze zones
- Supports stable temperature & humidity
- Integration with conveyor systems
- Interlocking of two doors for airlocks & pressure control
Sectors & Applications for ORS Doors
Oxygen high‑speed doors are used where goods are highly sensitive, high‑value or irreplaceable, and where fire and moisture are large risks. Typical sectors include:
- Archives & libraries – protection of historical documents, books & artefacts
- Museums & galleries – safe storage of fine art, film & media
- Pharmaceutical & chemical storage
- Warehouses with temperature‑sensitive & hazardous products
- Deep‑freeze warehouses for frost‑free, airtight spaces
- Electronics, aerospace, automotive & precision engineering manufacturing
In many cases people rarely enter airtight areas due to low oxygen levels. Products flow via conveyors passing through airtight high‑speed doors for complete continuity of the inerted atmosphere.
Airtight Door Performance with a Lower Cost
Not all inerted rooms need full cleanroom door specifications. Therefore, we have developed a cost‑effective, low‑leak door for applications where fire prevention and airtightness are required, but hygiene finishes are unnecessary.
For example, the EFA‑SRT CR Efficient high‑speed doors can be supplied in a galvanised version with modifications according to a general technical release which can reduce the cost and keep strong airtightness. We use this approach in Europe often in conveyor systems with high cycle numbers daily that require reliable conveyor ORS high‑speed doors.
Why Choose EFAFLEX for Oxygen Reduction Doors?
EFAFLEX has decades of experience in airtight, high‑speed and specialist‑use doors, which can also be applied to advanced oxygen reduction use cases in the UK. For example, we’ve worked with the British Library to implement low‑leak doors to protect their assets from fire. We are able to design, supply, install and service our supreme‑quality industrial doors for long‑term reliability and compliance.
If you are considering a proactive fire‑prevention strategy to protect products and keep logistics operational, the EFAFLEX door range offers the solution. To discuss your door requirements with us, speak to our specialist team today.
