Our mission

A2B aims first and foremost to serve customers. This service begins with an analysis of the current status of supplying power to a customer's critical technology systems, continues with the provision of expert advice and proposals for environmentally-friendly and the economically most advantageous solution, preparation of project documentation, project implementation, warranty and post-warranty servicing, and ends with the disassembly and ecological disposal of decommissioned technology equipment.


Our goals

To fulfil our mission 24/7, 365 days a year, and to support efforts that improve the quality, optimization and streamlining of activities and reduce the total cost of ownership (TCO).

To improve the quality of production and services by introducing innovative, environmentally ”clean” technologies and processes. To strengthen our position on the domestic and foreign market by consistently focusing on protecting the environment. To respond flexibly to rapid developments in process (critical) technologies, and the resulting changes in demands for the provision of uninterrupted power supply to those technologies.

To anticipate future demands in relation to the simplification of the maintenance and safety of servicing works on uninterruptible power supply systems, technology migration and upgrading, as well as changes related to increasing the power and volume of powered technology.


Our vision

To establish a strong position in Slovakia in the field of uninterruptible power supply to critical technologies in the key sectors of the national economy, and over the longer term to establish itself as a major player internationally.
