Pressure Management Systems
Pressure Management Systems for refuge chambers by MineARC are designed to help maintain a safe, breathable atmosphere within the refuge chamber.
Systems include the Pressurised Access Safety System (PASS) to ensure safe entry into the refuge chamber, and the Positive Pressure Maintenance System (PPMS) to maintain positive internal pressure within the chamber.
MineARC TunnelSAFE Refuge Chambers offer the PASS and PPMS as standard features, however, all other refuge chambers can be upgraded to include the systems.
The Pressurised Access Safety System (PASS) remote activation unit is located next to the door on the front exterior of the refuge, allowing personnel to prepare the chamber for safe entry.
Should the chamber’s fresh (mine) air supply be disconnected or compromised, the system’s external LED light will display red, indicating that the chamber is not positively pressurised and therefore unsafe for entry.
Once activated, the PASS will disperse controlled quantities of compressed air into the chamber until the internal pressure reaches 200 Pa. By ensuring that the pressure inside the refuge is slightly greater than outside, toxic contaminants are prevented from infiltrating the chamber during entry of personnel.
Aura-FX Digital Gas Monitoring Aura-FX Digital Gas monitoring is an essential aspect of maintaining a life-supporting atmosphere within the refuge chamber. During entrapment, occupants consume oxygen and expire carbon dioxide (CO2) and carbon monoxide (CO) as part of their normal respiration. CO can also enter the chamber during occupant entry and if the compressed air
Compressed Air Management System (CAMS) The Compressed Air Management System (CAMS) is a breathable air system that is unique to the market; offering a range of features aimed at reducing running costs and improving operational safety during an emergency. Aside from providing clean breathable air through a superior four-phase filtration process, some of the major
