DIGITAL SMART CONTROLS CONTROLLED EFFICIENCY The Nortek Air Solutions Cool 3 IDEC unit s smart digital controls prioritize the most energy efficient operating modes of the unit, allowing the unit to operate in the most cost-saving mode as often as possible. These smart controls also minimize the unit energy and water consumptions based on the outdoor air conditions and data center requirements. The Cool 3 IDEC unit switches between different operating modes, based on the operating conditions for optimum energy and water consumptions, and modulates the scavenger airflow rate to lower flow rates whenever possible for even more energy savings.

COOL 3 IDEC UNIT SAVINGS THROUGH THE SEASONS The Nortek Air Solutions Cool 3 IDEC Unit is an indirect evaporative cooling (IDEC) unit which sensibly and indirectly cools the data center air. The system minimizes the hours required to mechanically cool a data center because it operates in the economizer (winter) mode for more hours during the year (depending upon location) than its competitors due to having higher outdoor air dry-bulb (DB) limits. In addition, the outdoor air wet-bulb (WB) limit is very high and is slightly higher than the competition. These advantages result in significant water consumption savings and allow for a compact DX package size. WINTER Economizer Mode In this mode, the main outdoor air intakes are closed and the outdoor air enters the unit through the bypass dampers. The outdoor air bypasses the DEC, which extends the life of the DEC and reduces the pressure drop on the scavenger side of the unit. The sensible heat exchanger device carries 100% of the load by rejecting the heat from the data center air (process air) to the cold outdoor air. The scavenger airflow rate modulates based on the outdoor air conditions to minimize the unit s energy consumption in this mode. SUMMER Evaporation Mode In this mode, the bypass dampers are closed and the outdoor air enters the unit through the main outdoor air intakes. Firstly, the outdoor air (also called scavenger air) passes through the DEC where the scavenger air is cooled to its wet-bulb temperature. Then the cold scavenger air passes through the sensible heat exchanger device and will pick up the heat from the data center air. The scavenger airflow rate modulates based on the cold air supply temperature to minimize the unit s energy consumption in this mode. EXTREME Evap + DX Mode 12 When outdoor air is extremely hot and humid, the unit requires some mechanical cooling to bring the data center s air supply to its target temperature. Outdoor air passes through the DEC where the scavenger air is cooled to its wet-bulb temperature. It then passes through the sensible heat exchanger device where it absorbs some of the heat from the data center air. The DX cooling coil, which is in the process airstream and downstream of the sensible heat exchanger device, completes the cooling process and reduces the air temperature in the cold aisle supply to the need of the data center. The scavenger air fans run at their maximum speed in this mode.

MISSION CRITICAL EXPERIENCE AND EXPERTISE Nortek Air Solutions has three decades of experience providing cooling solutions to mission critical facilities. Here are a few examples of how we have helped data centers achieve their goals. Verne Global Data Center Keflavik, Iceland The N+1 data center achieved an impressive 1.21 PUE with efficiency contributed by the unique modular free cooling system from Eaton-Williams. This Verne Global facility is the world s first carbon-neutral data center. CyrusOne Data Center Since installing the senergy EMS system at the CyrusOne data center, cooling costs have been reduced by 40% and PUE has steadily improved from 2.7 to 1.4. Avid R&D Center The installation cost savings of a pre-engineered, factory-tested chiller plant from our Mammoth brand, combined with the continuous operating costs savings of the energy efficient magnetic bearing chiller, resulted in an estimated five-year payback. Large Hadron Collider Data Center Lyon, France The use of idataplex server cabinets and Eaton-Williams ServerCool cooling distribution units consumes 40% less power per kilowatt than the incumbent cooling system did. Centre for Scientific Computing University of Warwick The Eaton-Williams cooling solution has enabled the University of Warwick to introduce zero thermal impact into its data center and set performance benchmark for the University s other data centers. 13
