Driving innovation in data centre cooling, 2bm and Transtherm Cooling Industries successfully developed a budget-friendly, compressor-less cooling solution specifically for retrofitting into legacy data centres. Something which many data centre architects and their supply chain partners still shy away from attempting. A combination of industry education, intelligent specification and considered plant design, this solution pushes the boundaries for the good of budget-conscious data centre sites which would otherwise be forced to compromise on performance, energy efficiency and/or system life span.

Together, 2bm and Transtherm have proven that compressor-less systems are a logistically viable solution for every data centre in Europe, delivering best-in-class results, such as:

  • Up to 85% reduction in cooling plant energy consumption
  • PUEs of 1.12 and below during the hottest months of the year
  • An EER of 100 for 80% of the year

Rob Sewell, 2bm’s director for design and build, comments on the innovation of this industry best-practice solution: “There are a considerable number of data centres in the UK and across EMEA which are forced to compromise on data centre performance and efficiency due to budgetary constraints. We consider it vital to continually push the boundaries of design for the greater good of these sites, so that they too can improve their carbon emissions, water consumption, and performance metrics despite their legacy infrastructure. “We continue to develop and improve our compressor free cooling solutions to continually push the boundaries of design and allowable temperatures, whist providing a solution with increased redundancy and minimal parts to go wrong as well and removing and refrigeration gasses. “Our industry is progressive, and how we innovate must be progressive too. Not just for the key players, or the data centre giants, but for the smaller, equally as vital campuses, which often struggle to maintain end-of-life cooling plant in the absence of substantial refurb budgets. It is our collective responsibility as architects and manufacturers to create solutions for those facilities – not compromised ‘cheap’ solutions, but intelligently designed, cost-efficient solutions which are constructed to perform and to last in line with the most stringent standards.” There are a number of distinguishing features which differentiate this solution from those found in competing tenders for cooling upgrades on budget-driven legacy data centres: Challenging the “cold as it can go” mentality Educating data centre managers on server room temperature allowances rather than accepting the habitual “cold as it can go” mentality allows 2bm and Transtherm to work within the upper limits of ASHRAE guidelines for new and legacy equipment.

The pairing continue to educate the industry on challenging this mentality through considerable investments in marketing. Larger down flow CRAC units and adiabatic cooling methods Taking advantage of higher operating temperatures, they can employ adiabatic cooling methods rather than refrigerant-based or compressor technology.

Adiabatic systems work at elevated water temperatures to feed larger than normal down flow CRAC units and rear door heat exchangers which control the temperature within the facility. Low power EC fans for finesse of control and minimal noise Transtherm’s low power EC fans automatically adjust to deliver the lowest possible power consumption and the best finesse of control at any duty point. A standard specification for this joint solution, low power EC fans deliver class-leading noise reduction levels, making this solution ideal for sites where noise is a key concern.

Uncompromised performance on a restricted budget Budget restrictions often lead to debilitating compromises on specification standards, be that across performance, energy efficiency or lifespan. 2bm and Transtherm are tackling this notion head on, bringing to market a design and manufacturing solution which proves quality construction, optimised performance and impressive energy efficiency is simply a matter of intelligent specification, considered design and a passion to innovate.

Superior payback periods compared to equivalent chiller solutions By adopting ambient based water cooling technology, Energy Efficiency Ratios in excess of 100 are possible. Compare this with chilled water technologies where legacy equipment operates with EERs of circa. 3 and improving to 5-6 for more modern installations. Given that this equates to ambient cooling systems dissipating approximately 4 times the amount of heat for the same amount of energy consumption, it’s easy to see why going compressor-less for data centres where factors such as geographical location and weather patterns allow can save massive amounts of energy.

Exceptionally low water consumption Consuming around 1% of the water used by traditional cooling towers, and approximately 2% of that used by wetted surface hybrid dry coolers, this solution automatically employs a pulsed adiabatic spray operation to minimise water usage.

Intelligent features for maximum operational efficiencies Using a digital air thermostat, this adiabatic solution identifies when the ambient air temperature is cool enough to achieve the desired process water temperature through dry cooling only. Automatically triggering an integrated drain down function to empty the system of water and refilling it with a pre-programmed pre-purge function only when the ambient air temperature increases above the adiabatic trigger point. Once the adiabatic trigger point is reached, the system will only pulse for as long as necessary in order to maintain the required process water temperature. Only when the maximum design dry bulb temperature is reached will the system operate continuously.

Integrated inlet monitoring functionality for mission critical safeguarding Incorporating automatic monitoring capabilities which ensure the inlet pressure to the adiabatic spray booster pump, a signal alarm is triggered should the inlet pressure drop too low for correct functioning, resulting in the control panel switching to a standby spray booster pump.

Tim Bound, Director for Transtherm concludes: “With a cooling solution which is scalable to all legacy data centres, we are proud to be leading from the helm when it comes to educating the industry on the design and logistical flexibility of adiabatic technology as a direct replacement for compressor-based chillers. “Meeting the challenges of budget, noise reduction, energy efficiency and performance head on, our solution is a blueprint for industry best practice moving forwards.”
