E-UPS, Ex Power
EFC Zone 2 Uninterruptable Power Supply, (Ex E-UPS) provides backup supply for safety critical BOP and Well Control equipment.
The Ex E-UPS is particularly suited to Zone 2 control system panels and enclosures supplied for atmospherically controlled rooms.
If a purge unit fails this Ex E-UPS ensures safe, continued operation of the connected safety control system such as Driller’s BOP Control Panel. The unit has been specifically designed for continuous operation in Zone 2 Hazardous areas providing 2 hours autonomy.
Main power reverts to secondary and if both are lost this moves to battery giving a multi-layered protection meeting requirements DNV-OS-E101, standards relating to safety systems including managed PRS D, BOP & Diverter Control, Choke & Kill Control and High Pressure High Temperature (HPHT) instrumentation.
