Manufacturer of mechanical seals and support systems

AESSEAL®, one of the world’s leading specialists in the design and manufacture of mechanical seals and support systems, was suffering from power disruptions, interrupting their manufacturing processes.


AESSEAL® products are utilised in a vast range of pumps and rotating equipment worldwide to prevent liquids and gases escaping into the environment. Due to their critical application, AESSEAL® place the utmost importance on their products being produced to the highest and most stringent quality standards, which relies on the manufacturing processes operating without interruption.


After a thorough site survey and analysis of the site requirements, Powerstar recommended the installation of a 500kW/500kWh Battery Energy Storage System (BESS) with seamless Uninterruptible Power Supply (UPS) capabilities.

In the case of a power failure, the full UPS capabilities of the solution support the connected load within milliseconds without causing any interruption to the on-site equipment. The ability to protect the site against costly power failures interrupting critical business operations will enable it to continue delivering the highest quality components to its customers, protecting its reputation as well as minimising financial risk.

Additionally, the solution is able to simultaneously support the ambitious net zero objectives of AESSEAL® by maximising on-site renewable generation, and utilise intelligent microgrid control software to optimise the site’s power flows in real-time, reduce costs, carbon emissions, and generating revenue from grid contracts.

The Powerstar battery energy storage system, installed in 2019, is providing full UPS capabilities to the AESSEAL® site, increasing power resilience of the site and negating costly interruptions. Additionally, the system is being optimised to produce cost savings during peak tariff periods as well as generating revenue through grid contracts.
