SHELT’AIR EMERGENCY REFUGE CHAMBERS
Shelt’Air Underground Emergency Refuge Chamber: Intuitive Protection for Tunnels and Mines
Sub’Roca designs some of the most intuitive emergency refuge chambers on the market. A single action is all it takes to place your teams in a safe environment, whether working in tunnels or deep mining environments.
The Shelt’Air range meets the requirements of AFTES GT12, EN 16191, and ITA WG5 standards, with two configurations: an underground emergency refuge chamber for tunnels and an underground emergency refuge chamber for mines.
What Is a Shelt’Air Emergency Refuge Chamber?
An underground emergency refuge chamber is a secure, smoke- and toxic-gas-tight space where personnel can shelter while awaiting extraction in the event of a fire, explosion, or gas release.
The Shelt’Air range automatically maintains optimal air quality and a pressurized atmosphere for several hours, with up to 72 hours of autonomy, thanks to the AirGuardian© automatic control technology.

Four Ranges, One Standard
of Reliability

Tunnel
Emergency Refuge Chambers
SHELT’AIR Tunnel emergency refuge chambers are specifically designed to protect teams working on tunnel construction sites. Adapted to the constraints of underground works, they provide a secure, pressurized, and self-contained space where operators can shelter in the event of fire, smoke, gas release, or an inability to evacuate. Their optimized design minimizes the footprint while ensuring safety, comfort, and ease of operation.

Mining
Emergency Refuge Chambers
SHELT’AIR Mining emergency refuge chambers meet the demanding requirements of underground mining operations. Designed to withstand harsh environments, they provide reliable collective protection against toxic gases, fires, and emergency situations. Their robust design facilitates relocation on site while providing a high level of safety and availability.

Compact
Emergency Refuge Chambers
La gamme SHELT’AIR Compact a été développée pour les galeries étroites, les espaces confinés et les chantiers où chaque mètre carré compte. Malgré son faible encombrement, elle intègre l’ensemble des fonctions essentielles d’un refuge de secours afin d’assurer la sécurité des opérateurs jusqu’à leur évacuation.

SHELT’AIR Bay
Permanent Emergency Refuge Chambers
The SHELT’AIR Bay emergency refuge chamber range is designed for permanent installations in mines and underground facilities. Its design prioritizes occupant capacity, modularity, and comfort to provide long-term protection for teams working on extended-duration operations.
