he HRM6-ELVP (Hard Rock Mine, 6 Person, Extra Low Voltage, Portable) uses an extra-low-voltage control system to power the chamber’s internal life support systems which include CO / CO2 scrubbing and air conditioning / dehumidifying for a minimum 36hrs.

Because of the extra-low-voltage control system, the chamber can be left for extended periods (months), without connection to mains ‘mine’ power. Meaning you can take the chamber virtually anywhere, anytime – which is ideal for single entry headings and development faces.
