Containment Recommendations
Always use containment for optimal TCO o Payback is immediate with close coupled cooling o 3 year ROI for Room Based Cooling improves with density
Hot Aisle Containment preferred approach for new data center buildso Improved Efficiency of the Cooling Systemo Flexibility to keep data center cool.
Cold Aisle Containment – Retrofit for existing data center o Flexibility to adapt to existing room cooling systemso Active floor to assist with cold air distribution from raised floor to ensure
sufficient air flow is available in contained aisle.o Efficiency Gains Require elevating room temperature

Product Trade-Offs - Uniflair
UniFlair
Benefitso Flexibility to handle racked and non-racked IT equipmento Easily Deploy in existing raised floor environmentso Integrated redundancy on the electrical sections with double power
supplyo Possibility to optimize the airflow based on the operating conditions
(AFPS)o Low first costo Complete integration with the Uniflair chillers with dynamic optimization
of the operating parameterso Cooling equipment is located on perimeter of the room or in corridors
