VERTIV HAS UNVEILED the upgraded Liebert Air Handling Unit (AHU), a high capacity, chilled water cooling solution designed to sup- port high density compute environments while offering a more energy efficient approach to heat management.
The Liebert AHU has a standard unit capac- ity of 300kW, and is now available throughout Australia, New Zealand, Southeast Asia and India (ASI) region.
The new Liebert AHU chilled water unit uses water or air-side economisatons and high-effi- ciency EC fans, working with hot aisle contain- ment to avoid the mixture of supply and return air.
The Liebert AHU also operates at higher return air temperature and with higher chilled water temperature, increasing chiller efficiency.
With its highly efficient components such as Electronically Commutated (EC) fan, Pressure
Independent Control Valve and intelligent con- troller with multiple remote temperature sen- sors, the Liebert AHU supplies proper airflow, temperature, and humidity for supported criti- cal IT equipment.
The new model of Liebert AHU is completely chilled water based, and designed with a fan wall configuration that allows for a smoother supply air distribution and higher efficiency hot aisle containment, compared to the previous model. It is designed to achieve the highest standard for fan efficiency of up to 0.2W/CMH. This model has a smaller unit depth, can be modularly installed and is easily serviceable.
The Vertiv Liebert AHU adapts easily to a non-raised floor design simplifying installa- tion, shortening deployment time and reducing associated costs, compared to raised floor sys- tems. The Liebert AHU cools high-density
servers through horizontal air discharge, deliv- ering an even airflow distribution and uniform temperature across the data hall.
The Liebert AHU also allows provision for redundancy or future expansion as it requires no clearance in between units and may be positioned side by side seamlessly. Each unit is built to last and CE Certified for safety and reliability. During maintenance, personnel can access the components from the corridor side and no longer need to enter the data centre hall.
Its modular installation and non-raised floor application makes it an ideal choice for manag- ers aiming to both reduce CAPEX and flexibly deploy cooling units as demand grows.
