The high levels of power used and subsequent heat generated in server systems are the principle causes of fire in data centres. With data centres now covering hundreds of thousands of square metres, a small fire caused by a fault in just one piece of equipment or wiring can potentially spread to cause incalculable damage to the operator’s assets and reputation.

There is lots written, and we all know, about availability and resilience through use of parallel redundant UPS topologies be it multiple monolithic units or the Modular design UPS systems. However, not every application requires such resilience and for these organizations, a stand-alone UPS can be a simple cost-effective solution.
These days, a multitude of stand-alone UPS units are readily available, google uninterruptible power supply systems and there will be a bewildering number of suppliers and manufacturers. However, not every stand-alone UPS offers the same benefits and quality of power protection. So, when it comes to selecting a stand-alone UPS how can smaller organizations ensure they still have ‘best of breed’ power protection for their business-critical applications?
Choosing a quality manufacturer is key. CENTIEL’s stand-alone UPS: PremiumTower for example, uses the same innovative technology incorporated in CENTIEL’s 4th generation modular three-phase UPS system and has an unbeatable on-line operating efficiency of 96.6% which minimizes running costs. PremiumTower is currently available in power ratings of 10kW – 120kW, a range of frame sizes including built-in batteries which significantly reduces footprint to ensure it can fit into even the smallest comms room.
However, it is not just the quality of the UPS system itself which will influence levels of reliability and availability. A system needs to be properly maintained to remain both efficient and reliable and therefore available. When purchasing any UPS system, it is therefore, essential to understand who will be responsible for maintenance and support.
Be sure to analyse the service level agreement (SLA) to find out the guaranteed call response time? Find out what the is included in the schedule of preventative maintenance visits? Is there a 24-hour support hotline? It is also necessary to find out if labour, traveling, and expenses are included and who is responsible for the cost of replacement parts.
Further, if there is no valid warranty or proper maintenance and support contract, the whole power source could be compromised however good or cost-effective the initial technological solution.
The challenge is that cost reduction has become a big driver and criteria for winning contracts, but if cost-cutting compromises the quality of the chosen UPS then the critical load will not be properly protected.
A recent real-life example was where we needed to advise a healthcare facility which had imported a large number of stand-alone UPS units from another manufacturer. Multiple UPS units were simply not working and there had been problems in commissioning the units from day one. There was also frustrating slowness in the communication with, and between, the local supplier and the actual manufacturer.
The major challenge was that a proportion of the UPS units were needed to protect the load in individual operating theatres at the healthcare facility. Without reliable power protection, people’s lives would have potentially been put at risk. Fortunately, the healthcare provider was quick to recognise the issue and address the problem. This is a clear example where up-front cost-cutting could have directly compromised the quality of the UPS system with potentially disastrous consequences.
Where possible look at obtaining your UPS system direct from the manufacturer, or their local subsidiary, so you are talking directly with them in the event of any problems.
The challenge for any manager is to balance the cost of a UPS system and its quality. To achieve this, it is essential to study the technical submittals evaluation documentation carefully regardless of the size of the UPS being purchased.
And, my own personal bugbear…battery systems!! Even with a single standalone UPS unit, you can still provide some resilience, especially in the design of the associated battery system. At the very least utilise two strings of batteries, so that in the event of failure of one string then you still have some battery back-up, individual string isolation is a must!
At CENTIEL our design team works at the forefront of technological development. We are the trusted advisors to some of the world’s leading institutions in this field. For this reason, we have developed both standalone and modular UPS systems which offer industry-leading availability, with low total cost of ownership (TCO) through Maximum Efficiency Management (MEM) and low losses of energy.

The potential introduction of Lithium ion (Li-ion) batteries for UPS systems has been much debated in recent times. However, the fact is that advances in technology have now reached the point where Li-ion is a safe and commercially viable option, to protect the power for critical installations. Ahead of Data Centre World London, CENTIEL’s design team; who were originally at the forefront of the industry to develop the first three–phase transformerless UPS and now the fourth generation of the technology, has announced the launch of our Li-ion UPS solution. In this article, we aim to address some of the misconceptions surrounding Li-ion and by putting the record straight, explaining why Li-ion may well be the battery technology of the future for many years to come.
CENTIEL’s Li-ion solution is already being installed by our most forward-thinking clients, who are looking to capitalise on the advantages that Li-ion has over lead-acid batteries, namely: smaller, lighter, high power density, have a longer life and operate at higher temperatures.
We anticipate that a significant industry changeover to Li-ion will most likely be over the next five years, but unlike CENTIEL’s technology, not all UPS systems on the market are compatible. Not all systems are Li-ion ready, but they need to be.
One of the main drawbacks of switching to Li-ion up until now has been the cost. However, prices are being increasingly driven down by the automotive industry and have reduced significantly over the past ten years. Increasingly we are being asked to provide comparative quotes for Lead Acid versus Li-ion batteries for UPS installations. Depending on the project, we are generally finding the initial CAPEX cost of buying Li-ion compared with Lead Acid batteries works out at around twice as expensive. However, Li-ion lasts twice as long and so considerations relating to total cost of ownership (TCO) have now started outweighing concerns about the initial investment.
Li-ion batteries had their origins in the early 70s. Continued growth and development has been driven by laptops, then mobile phones because we all want our electronics to be smaller, cheaper, more powerful and operate for longer periods. These days, progression is such, Li-ion is being used to power our electric cars. There are some publicised stories about the fire risk of Li-ion technology over the years. However, any technology which is not managed correctly is potentially hazardous. If the proper procedures are not followed it is dangerous to drive a vehicle, fly a plane or even just cross the road!
Li-ion batteries are more sensitive to how they are charged and discharged and therefore need to be linked to a monitoring and control device. CENTIEL’s Li-ion battery monitoring system collects and reports data in real time. This system provides early warning alarms ahead of any issues and automatically shuts down faulty cells if necessary. With Lead Acid, you may only know there is a battery problem when you need to use it and if it doesn’t work then it’s too late!
In addition, the more modern Li-ion batteries have been developed with a ‘belt and braces’ approach and can include numerous further safety features such as: steel containers, internal separators that melt at high temperatures to shutdown conductivity, current collects from opposite end of its pack ensuring there are no hotspots at high current density areas ,and improvements to cathode material which is more stable during overcharge.
Every battery including Lead-acid batteries are a potential hazard but managed correctly, Li-ion technology has now been developed to be safe to use in Data Centres and other facilities requiring critical power protection.
Li-ion batteries typically require less than half the physical space of the equivalent Lead Acid blocks and less than 25% of the weight. Commonly, above ground-floor installations can require structural strengthening of the building simply to house the required battery systems. Logistically, moving many tonnes of equipment in and out of an upstairs comms room, when batteries need replacing, can also present challenges. For data-centres looking to increase their power density within the same foot print Li-ion promises a practical solution.
Length of Life
One of the main benefits of Li-ion is length of life. Ten-year design life Lead Acid batteries are normally replaced every seven or eight years. With Li-ion this is 13-15 years.
Switching to Li-ion could also improve the overall efficiency of the comms room. This is because a further advantage of Li-ion is that it can work at a higher temperature, therefore requiring less cooling, reducing the amount of overall energy consumed. Most IT systems work at >250C and the UPS technology itself can work well up to 400C. By contrast: an industry standard estimate is that for every 10 degrees above 200C the operating life of a VRLA battery is halved. With growing concerns about reducing the carbon footprints of datacentres, being able to decrease and remove the electricity requirement for cooling could become an increasingly attractive and important consideration.
The up-take and roll-out of Li-ion across the datacentre industry will not happen overnight. Not all systems are Li-ion ready, manufacturers of UPS equipment need to ensure their technology is compatible and can ‘talk’ to the Li-ion battery monitoring system.
Interestingly, the adoption of Li-ion within UPS systems so far, has been greater in developing countries in Africa and the Middle East, where the main power grid is less reliable than in the UK and frequent power problems are more commonplace. In these instances, the UPS and battery systems are required to be cycled several times per day. This greater adoption is primarily due to the higher cycling life of Li-ion: typically, 2,500 power-up and down cycles compared with around 300 for VRLA technology.
Over time, we believe, there will be an inevitable shift towards Li-ion batteries as further cost reductions driven by developments in the automotive industry, flow through to the standby power sectors. Incorporating Li-ion will inevitably reduce the size and weight of UPS systems overall and the longer useful working life of Li-ion will mean fewer costly replacements. All of which will benefit customers with reductions in both CAPEX and OPEX and make Li-ion batteries a winning solution for UPS applications requiring compact, innovative protection.
In our ever-evolving world, future-proofing systems is one of the greatest challenges faced by system designers. The good news is that CENTIEL’s technology is already Li-ion Ready, so existing lead acid battery installations will have the option to upgrade to Li-ion in the future without needing to replace the UPS.

The priority of any UPS is to protect the critical load and keep it running as long as possible in the event of a power loss. We often talk about developments in modular technology and the associated benefits, such as improved availability and reduced downtime, however, not all project budgets allow for a modular solution.
When cost reduction is a driver for winning contracts, a standalone UPS is a good solution. Choosing a UPS that offers built-in internal batteries eliminates the hidden cost of external battery cabinets while minimising the overall system footprint. A UPS that has a small footprint and is easy to install initially, will provide a smoother handover for contractors and clients alike.
Another consideration when choosing a UPS is Total Cost of Ownership (TCO). Purchasing poor quality or inferior designed products can rapidly drive up overall investment costs as batteries and other components may need to be replaced within a short time span.
Purchasing directly from a manufacturer also cuts out the ‘middle-man’ reducing cost and providing the peace of mind of full factory support and servicing, plus a 2-year factory warranty.
At CENTIEL our design team works at the forefront of technological development. We are the trusted advisors to some of the world’s leading institutions in this field. CENTIEL’s stand-alone UPS: PremiumTower for example, has an unbeatable on-line operating efficiency of 96.6% which minimizes running costs.

New research launched today by Blancco Technology Group (LON: BLTG), the industry standard in data erasure and mobile device diagnostics, outlines the staggering cost to global organizations of old, outdated IT equipment cluttering up data centers. A survey of 600 data center experts from APAC, Europe and North America reveals that two in five organizations that store their data in-house spend more than $100,000 storing useless IT hardware that could pose a security or compliance risk.
Protecting critical power properly with a UPS system, means you need a system with a high level of availability. Availability is the probability that a system is operational as and when required – in other words, providing power when the main power source is interrupted or even fails. In addition, for most organisations, efficiency is also high on the UPS tick list in order to keep costs under control.
The most modern, scalable, and flexible modular type three-phase UPS systems that combine class–leading availability and efficiency are perfect for use in small, medium and large datacenters. However, not every application requires a modular UPS and for these organisations, a stand-alone UPS can be a cost-effective solution.
