Data Centres

In a recent report by “The shift Project”, it is estimated that data centres account for around 10% or all energy used in the world and 3.7% of all greenhouse gas emissions.
According to the latest research figures, the UK data centre market will reach a value of almost £6.5 billion by 2025 and so the energy use and resultant carbon emissions are set to grow further
After the IT load, cooling isthe most significant energy user in theseestablishments. The nature of data centres means that there is an almost constant load, 24 hours a day, 365 days a year.
Cooling equipment is likely to be electrically driven and often consumes more than40% of all electricity used in a data centre.

What if your cooling costs could be cut in half?

What if you could generateelectricity on site and produce cooling as a bi-product?

Manzana work with data centre opeators to reduce energy costs and carbon. We offer a free off charge site audit to identify quick pay back energy efficiency measures.

All solutions can be financed, meaning zero upfront investment. We target solutions with 2-3 payback, that can be financed over 4-6 years, making it profitable from year 1.

For operators who are more serious about energy reduction, we can help you develop a full energy transition strategy. Working with our partners we can provide a number of funding options for energy transition projects:

Energy savings agreements – 0% investment or repayment. Running cost savings shared between you and funder

Hire Purchase agreement – 0% upfront investment, repayments circa 50% of savings. Equipment is your asset from day 1 attracting enhanced capital allowances.

Lease Purchase agreement – VAT paid upfront (20%), repayments circa 60% of savings. Off balance sheet option.

You can of course purchase our solutions without finance. After the 2 -3 year payback period, all savings are then yours!

We have many solutions to reduce energy use and running costs in data centres, here are some of our favourites:

Free Cooling Chillers with Zero Global Warming Potential

Do you want to get rid of refrigerants with global warming potential on site? What if we could reduce energy consumption by up to 40%? Would that save lots of running costs? Did you know that some chillers use water as refrigerant?

Our R718 chillers, use water as a refrigerant and are perfect for data centre cooling applications.
Using water instead of another refrigerant, means that the units offer an unrivalled option by offering cooling with a zero GWP refrigerant. The units also feature free cooling, which can provide 100% free cooling when conditions allow, but also allowing partial free cooling while compressors are running. Due to the optimisation of components and free cooling, these units are able to provide seasonal energy efficiency ratio’s (SEER’s) of up to 11. This is an expression of the efficiency, for every 1kW of electrical input, 11kW of cooling energy is provided.

Does this sound like the sort of future you wish for your children’s, children?

Magnetic Bearing Oil-Free Chillers

Do you have existing chilled water chillers? Are they as efficient as they could be? What do they cost you to run? What if this cost could be reduced by 50%? Would that save you lots of energy and cash?

Magnetic bearing oil free chillers use advanced technology to deliver high efficiency and low sound levels in a compact footprint. Industry leading performance is achieved by using oil free, magnetic bearings that provide world class efficiency and zero performance degradation over the life of the compressor. Permanent magnet motors and variable speed drives provide unmatched full and part load efficiency. Conventional chillers use oil to lubricate the compressor, with time this oil can reduce efficiency performance by up to 30%. Magnetic bearing chillers do not use oil and so do no suffer loss in efficiency due to this. There is also zero friction, no resistance and so much lower energy use.

  • Up to 50% more efficient than conventional chillers
  • Replacing existing chillers offers payback circa 2 years and then 10’s or 100’s of thousand’s savings annually
  • No reduction in efficiency due to oil degradation

Chilled Water Systems Which Simultaneously Generate Electricity

Is your data centre currently cooled using chilled water? Would your site benefit from low costs electricity? What if you could generate electricity on site and as a bi-product, produce chilled water to cool the data centre?

Combined heat and power plant (CHP), can be combined with an absorption chiller, to produce both electricity and chilled water. Gas driven CHP engines generate electricity and as a bi-product, hot water. This hot water can then be used to drive an absorption chiller, which in turn produces chilled water. This type of system is sometimes described as tri-generation, as you are producing heat, cooling and electricity using one system. allowing the bi-product heat to be fully utilised to satisfy the site cooling demand.

Main Benefits of Tri Generation

  • Reduces sites actual energy costs
  • Avoidance of Climate Change Levy
  • Claimable Enhanced CapitalAllowances
  • Stabilises energy costs overa period of time
  • Acts as back-up generator
  • Back-up cooling supply
  • Reduces grid dependency
  • Funding & Finance available meaning zero upfront cost
