LET’S LOOK AT ROI
How does the payback of the retrofit compare to the purchase and installation of a new energy-efficient cooling unit?
A new energy-efficient cooling unit will typically have a power draw of 6 kW and cost in the range of $150,000 for purchase and installation (including removal of the old unit). A retrofitted unit will see an improvement of 40% in energy reduction bringing its power draw into the 10 kW or less range. Looking at the energy savings of the two approaches, the energy-efficient unit would have an annual energy cost saving of about $7,500 compared to the retrofitted unit. To payback the difference in cost to go with the energy-efficient cooling unit would take over 15 years.
IF YOU STILL THINK THE PURCHASE OF A NEW COOLING UNIT IS A GOOD CHOICE, ASK YOURSELF
- Will my current data center still be operational for the next 10 -15 years? The life of a cooling unit would be in the 15-year range and the cost to relocate cooling units is high.
- Will existing IT services be moved to the cloud – less IT load means less cooling required?
- Will IT applications be virtualized – less heat load so is more cooling needed?
- Do I want the disruption of removing an old cooling unit and installing a new one?
- Is the plan to go with the same cooling capacity or more than the old unit – do I actually need additional capacity?
- Do I want to invest the capital at this point not knowing what the future of the data center may be?
KEEP IN MIND
Having older cooling units doesn’t mean they need to be replaced as there is a lot that can be done to improve the energy efficiency of the unit.
Retrofitting older cooling units is done with very little disruption to the site.
We’ve successfully retrofitted over 225 cooling units. The floating head retrofit takes one week per unit and either during or at the end of the retrofit we train your HVAC contractor on changes that were made. From an ongoing maintenance perspective, the floating head retrofit will have no impact on the contractual agreement you have with the HVAC contractor.
In actual fact, most HVAC technicians prefer working on the retrofitted units as part of the retrofit includes updated displays which provide them with better information on the operation of the CRAC unit.
