Mega AHU for Data Centers
Maximum Energy Efficiency for IT Infrastructures

The Mega AHU by Martèl s.r.l. is a gigantic Air Handling Unit engineered to eliminate internal resistance and minimize energy consumption (PUE) in hyperscale and colocation data centers.

Direct Free Cooling Technology

The technological heart of the Mega AHU is based on the integration of advanced ventilation and control systems.

  • Climatic utilization: It exploits outdoor conditions to eliminate compressor usage for most of the year.

  • Direct free cooling: Outdoor air is filtered and supplied directly into the server rooms.

  • Energy saving: It guarantees a drastic reduction in operating expenses (OPEX) and immediate optimization of the PUE.

 

Technical Specifications and Operation

  • Extraordinary airflow: The structure can handle 2,000,000 m³/h of air or more.

  • Cutting-edge dimensions: An architecture that can reach dimensions of 31 x 20 x 8.5 meters.

  • Industrial framework: Special construction akin to Martel's proven Pack Export® system.

  • Optimized flow: Industrial fans coupled with high-efficiency filters and integrated evaporative or mechanical cooling sections.

  • Homogeneous delivery: Uniform distribution of the cold airflow into the data center aisles to prevent thermal fluctuations.

 

Fields of Use and Sustainability

  • Hardware protection: Total security and operational continuity for servers and sensitive data.

  • Carbon Footprint reduction: An eco-friendly solution designed to lower the environmental impact of large digital infrastructures.

References and Case History: The World Record with ENI
The validity and efficiency of the Mega AHU technology are proven by important successes in the field.
ENI Green Data Center (Two-year period 2012-2013)
Thanks to the installation of 3 Mega AHUs developed by Martèl s.r.l. in collaboration with SIEMENS and based on a project by the ARIATTA studio, ENI set the world record for energy efficiency for its Green Data Center.
The Martel cooling system allowed the infrastructure to position itself at the top of European and global rankings for sustainability and industrial computing power. For more details and to view videos of the plant, please consult the page dedicated to ENI Data Center references.

100% Custom Solutions
The Mega AHU does not follow standard industrial models. Each unit is custom-designed based on the room layout, the thermal loads of the racks (kW), and the client's efficiency goals.
Partner in Digital Development in Italy
We are proud members of IDA (Italian Data Center Association). Together with the main players in the sector, we work to define the standards of future digital infrastructures, promoting energy efficiency, environmental sustainability, and technological innovation throughout the national territory.
