Rack
Supercapacitor Rack
A rack-scale supercapacitor system that installs right beside your compute racks. It smooths AI power spikes before they reach the rest of the facility.

Applications
The Rack sits beside compute racks and absorbs the millisecond power spikes of AI training loads. Smoother demand at the rack helps protect upstream UPS systems, generators and utility service.
When grid power drops, the Rack carries critical loads through the seconds it takes backup generators to start and stabilize. That bridge keeps servers online without oversizing battery UPS systems.
Flattening rack-level volatility gives utilities a steadier, more predictable load profile. That can help data centers make the case for new interconnection capacity.

Applications
floMOD modules provide peak shaving inside standard 19" racks, buffering fast GPU load swings close to the source. Modules can be combined to match the power envelope of each rack or row.
In a microgrid, floMOD modules handle fast power fluctuations so batteries and generators can run at steadier output. That can extend battery life and improve stability when the site is islanded.
Commercial and industrial sites use floMOD modules to ride through short outages and voltage sags that interrupt sensitive equipment. A few seconds of reliable power can prevent lost production and costly restarts.
Paired with power electronics, floMOD modules supply the fast-responding power behind artificial inertia and frequency support. Their long cycle life suits grid services that cycle many times a day.
Cells
floCAP™ supercapacitor cells
High-power supercapacitor cells that bridge the gap between capacitors and batteries. The building block inside every florrent module and rack, rated for 10 years of service.

Applications
floCAP cells deliver bursts of high power instantly, which suits UPS systems that must respond in milliseconds. Long cycle life means far less frequent replacement than battery-only designs.
Pairing floCAP cells with batteries lets the supercapacitors take the high-power peaks while batteries supply sustained energy. That split can shrink the battery footprint and extend its lifetime.
floCAP cells can be built into systems that smooth the rapid output swings of solar and wind. Fast response helps keep voltage and frequency within limits as renewables penetration grows.
