Refuge Chamber
 
Primary and back-up operation

Strata Refuge Chambers are equipped with a standard 36 hours of battery and air back-up supplies. These systems are upgradeable to 96 hrs. Backup power is provided by a bank of 12 volt batteries and backup air is provided by on-board oxygen cylinders and an active soda lime carbon dioxide scrubber.

Primary operation includes attaching to main airlines and power sources. The refuge chamber then has an indefinite supply or air and power. If the refuge chamber loses power there is a 36 hour battery back-up system that provides emergency power to the scrubber, air conditioner, lighting and warning systems.

All chambers come standard with fork lift slots, lifting and towing lugs for ease of movement throughout the mine.
