Fact: Conventional UPS/standby batteries are expensive to maintain and may fail to perform when needed

Fact: Compressed Air Batteries cost less to operate, are low maintenance and consistently dependable

System overview

How they work efficient power train

Energy is stored in compressed air cylinders and regulated through control valves to rotate the scroll expander. This drives a generator to support the load. instant performance The scroll starts extremely quickly (200 milliseconds) and ultra capacitors are used to bridge the gap
between the grid outage and the scroll generator spinning up to speed.
