BATTERY BACK-UP OPTIONS

Fully automatic battery backup systems and specialized multi-stage chargers are standard on all chambers. The chambers are connected to local power to maintain the charge on the battery but will automatically switch to battery power should the local power be disrupted. 

Batteries are located either at the rear of the chamber, or stored on a pull-out “tray” at the entrance of the chamber. This design option provides added convenience in accessing batteries for maintenance. Batteries can be bundled in portable packs to optimize handling and transportation.

 

CUSTOMIZATION

Strata specializes in custom construction of refuge chambers and can vary structural dimensions to meet individual mine needs.

Wheel and hitch packages are available to assist in moving the chambers into and around the mines and in restrictive areas.
