& Upgrades

   
    
Virtually all aspects of a MineARC Refuge Chamber or Safe Haven design can be customised by our in-house team of engineers, including; dimensions, structural integrity, volume, occupancy and minimum entrapment duration.
    
MineARC offers a range of options and upgrades based on industry and application.

 

PRESSURISED ACCESS SAFETY SYSTEM (PASS)

 

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.

POSITIVE PRESSURE MAINTENANCE SYSTEM (PPMS)

 

Positive Pressure Maintenance System_Internal
The Positive Pressure Maintenance System (PPMS) enclosure is securely mounted to the interior wall of the refuge chamber. Powered by a 24VDC power supply, the electric solenoid valve opens and closes to release measured amounts of breathable air from compressed air cylinders in order to maintain a positive internal pressure.

The quantity of compressed breathable air cylinders is configurable to suit various internal volumes and durations of operation.

 

MineARC TunnelSAFE Refuge Chambers offer the PASS and PPMS as standard features, however all other refuge chambers can be upgraded to include the systems.

  • GuardIAN Remote Monitoring & Diagnostics

    MineARC’s GuardIAN Remote Monitoring and Diagnostics System is an exciting new development in refuge chamber technology. GuardIAN enables real-time monitoring; providing confidence that an operation’s fleet of refuge chambers are emergency ready at all times.
     
    GuardIAN is an independent system that continuously monitors all vital refuge operating systems. During standby mode GuardIAN checks for component faults and monitors refuge chamber usage or entry to the chamber.
     
    GuardIAN is available as an option on any new MineARC Refuge Chamber or Safe Haven, and also to retrofit to existing chambers during an upgrade or refurbishment.

  • Aura-FX Digital Fixed Gas Monitoring

    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 intake is compromised.
     
    Closely monitoring gas levels in the chamber allows occupants to take corrective actions to maintaining a safe and inhabitable environment.
    MineARC’s new Aura-FX Digital Gas Monitoring System is a proprietary fixed gas monitoring unit, designed specifically for use in refuge chambers and safe havens.
     
    Aura-FX is standard on all new MineARC Refuge Chambers and Safe Havens. It is also available to retrofit to most existing chambers during an upgrade or refurbishment.

  • Airlocks & Vestibules

    MineARC airlocks and vestibules are designed to act as a staging area between the enclosed protection of the chamber and the outside environment.
     
    They feature positive pressure flushing systems that ensure the out-flow of air; preventing the ingress of contaminants while the door is open for entry. The Positive Pressure Flushing System (PPFS) provides high speed pressurisation and is activated via a simple electric push-button system.
     
    MineARC offers a range of internal and external vestibule solutions designed to suit a wide variety of applications and entry requirements.

  • Blast Rating Upgrade

    An optional feature for all MineARC Refuge Chambers and Safe Havens is a blast rating upgrade.
     
    MineARC utilises highly specialised materials and engineering techniques to build chambers that can withstand the concussive forces of extreme blasts and explosions within heavy industry. Through careful analysis of a site’s application and hazard assessment, MineARC can engineer a highly customised refuge chamber or safe haven to meet their specific blast rating requirements.

  • Blast Shield Protection

    MineARC can provide structural additions to a refuge chamber or safe haven in order to provide blast shield protection for susceptible components.
     
    This added protection prevents damage to areas of the chamber that either provide life support (such as air conditioning and mine air filtration) or components that, if damaged, will compromise the breathing integrity of the chamber (such as the portal window). – More information

  • Scoop Frame

    MineSAFE Compact Design Chambers can be upgraded to include a ‘scoop’ or ‘bogger’ frame, designed to enable easy transportation via an integrated tool carrier or front-end loader.
     
    Available only for 4 and 6 person chamber models due to weight restrictions, the scoop frame adds another element of maneuverability to the portable design. – More information

  • ITHitch

    MineSAFE Compact Design Chambers can be upgraded to include an IT hitch, enabling easy lifting by an integrated tool carrier.
     
    Available only for 4 and 6 person chamber models due to weight restrictions, the hitch adds another element of maneuverability to the portable design. – More information

  • Compressed AirManagement System

     
    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 benefits of CAMS include; optimisation of mine air services, guarantee against over pressurisation of the refuge chamber, gas toxicity monitoring, flood protection, and reduced service time during filter change-out.
     
    Currently owned chambers can be upgraded with the CAMS upon request. – More information

  • Automated Oxygen Delivery System

    The MineARC Automated Oxygen Delivery System (AODS) is designed to maintain a safe, breathable atmosphere within the refuge chamber.
     
    Once the system is activated, the AODS disperses metered amounts of Oxygen supplied by a compressed Oxygen cylinder. The AODS maintains Oxygen levels between 18.5% and 23% inside the refuge when the external fresh air supply has been compromised or is unavailable. – More information

  • Series IV Scrubbing System

     
    The MineARC Series IV Electrical Scrubbing System is considered to be the most advanced safe refuge technology in the world. The Series IV boasts all of the improvements of the Series III system, plus a host of additional features including a superior digital control system and intelligent voice audio navigation (i.V.A.N).
     
    Additional improvements include pre-packaged MARCISORB Chemical Cartridges, intuitive operation, motion sensor logging and a modular controller design. – More information

  • ELVP / ELV Scrubbing System

     
    MineARC’s unique ELVP/ELV (extra-low-voltage) Scrubbing System works in conjunction with active chemicals to ‘scrub’ the build-up of harmful CO2 and CO from the air inside the refuge chamber.
     
    The ELVP/ELV represents six years of technological advancements to the original PLP (powerless portable) scrubbing system, in a safer, more reliable design.
