Energy solutions supplier Critical Power Supplies has added Flow Battery’s compressed-air battery system to its product portfolio.
The Pnu Power system for uninterruptible power supply (UPS) applications uses compressed-air cylinders to drive a scroll generator that is designed to deliver up to 4kW of AC or DC backup power, according to Flow Battery.
The compressed-air battery system aims to be more cost-effective in comparison to conventional UPS and more reliable than lead-acid batteries. The system has a low maintenance and a consistent performance, claimed Chester-based Flow Battery.
The service life of the Pnu Power range is expected to be more than 40 years.
Flow Battery recently installed a compressed-air backup at National Grid’s Elland substation in Yorkshire, UK.
