A long-standing history based on experience and trust
The former Power Cooling division of GEA Group AG - ranges from Air Cooled Condensers, Heller Technology® and Wet Cooling Towers including Service for Wet and Dry applications to 2H Water Technologies – operates separately and independently under the name ENEXIO.

ENEXIO is a reflection of what we do and what we have accomplished as pioneer in the field of industry-, process-, and power plant cooling as well as water and waste water treatment over decades. At the same time, our name is a promise to our customers and business partners – ENEXIO stands for Energy. Engineering. Excellence.

With our experience and pioneering spirit in engineering, manufacturing and service, we deliver state of the art solutions for power plants, water and wastewater applications – always inspired by our profound sense of responsibility for the overall management of resources and a clean environment. We deliver excellence and achieve customer satisfaction everywhere in the world. Our global network of employees work with an unceasing commitment to high quality, ecology and cost effective products and services.

What our commitment to Energy, Engineering and Excellence means for you is that we are a reliable partner who is always there to meet your expectations with superior results. More than 80 years in the market and a great deal of success have made us a leading manufacturer and solutions provider worldwide of both wet and dry cooling systems.

Depending on customer requirements, we can provide any type of cooling solution for power generation efficiency while assuring cooling water economy. Our rich product portfolio ranges from all dry air cooled condenser (ACC) and Heller technologies to all wet cooling towers, with limitless dry/wet combination systems and evaporative add-on solutions in between.

In addition to our core power cooling solutions, we also offer cooling tower, water and wastewater components that ensure a high degree of operating safety and environmental protection. The ecological Circumix technology —as a comprehensive solution to ash and waste water management in coal fired stations — completes our extensive portfolio.

The diversity of our designs provides customers with extremely eco-friendly solutions and a minimum of operating and maintenance costs. Underlining our responsibility as a reliable partner, we also offer customers comprehensive maintenance and spare parts service, developing and manufacturing all of the main components at our own production sites.
