Xamax – Think Energy Management
As a specialist in energy management for over 30 years, Xamax offers a comprehensive solution for companies that want to reduce their energy costs and efficiently control their energy flows. From meter data collection and visualization to automatic control, Xamax handles all essential tasks: peak load optimization, reactive current compensation, transparent consumption of electricity, gas, water, or compressed air, and intelligent load management for e-charging stations. This allows us to create a clear basis for decision-making – with potential savings from day one.
