How To Avoid A "Frankenstein" UPS
July 15, 2013 - Contact FacilitiesNet Editorial Staff »
To reduce the risk of getting a "Frankenstein" system of mismatched components in large UPS systems for data centers, it's important for facility managers to understand the importance of selecting a vendor with a substantial and experienced U.S. sales and service organization.
These concerns with buying complex systems from marginal players in the marketplace are well-understood among industry veterans. These concerns with UPS systems are not much different than with other complex data center support equipment technologies such as redundant standby generator systems and HVAC systems, especially central plants or HVAC systems with economizing features.
One additional key factor is not always well-understood. When an order is placed with a vendor for an integrated system of components, it is up to the vendor to pull together all the correct and compatible components and see that they arrive at the jobsite, at the same time, or are otherwise sequenced as required by the construction team. A large "single module" UPS system can require the main UPS box, boxes full of batteries, sometimes a separate battery disconnect box and often a separate maintenance bypass box, sometimes all shipping from different factories and often from different sub-vendors.
Without a strong technical sales application team, the system may not get properly represented and applied with appropriate accessories or it may not get delivered correctly in accordance with customer needs. Without a strong regional service organization, routine preventive maintenance and minor issues can lead to big problems, such as excessive planned or unplanned downtime or excessive repair time.
Imported UPS units are often matched with domestically designed and assembled battery and bypass packages. Sourcing these components is often left to the domestic sales organization, which is usually different in each marketplace. Often, a buyer thinks (or hopes) all of this equipment will be integrated together or even tested as a complete system at the "main factory or assembly plant." This is rarely the case, as it would add significant cost. Getting these different components to show up correctly at the jobsite is where the marginal players often fall down on the job.
