Solutions for hot data centres

Turbomiser III draws interest at HE show

WELCOME from the MD

Welcome to the first edition of Cool-Therm’s new company newsletter. The aim is to keep you up-to-date with developments in cooling technol-ogy and business, to help you keep ahead and remain competitive. It is an exciting time to be in the re-frigeration, air conditioning and data centre cooling sector. Advances in technology are opening up new ways of cooling that dramati-cally reduce energy costs and improve performance and reliability. I am particulalry proud to report that our ultra-efficient Turbomiser chiller has scooped two more prestigious awards for more than halving cooling energy costs at Colt (see report over the page). The story is being repeated on scores of sites across the UK, as the remarkable efficiency benefits of the oil-less, magnetic bearing-based chiller become established beyond doubt. It was a great pleasure to welcome Roger Vidal of Saifor during his recent UK visit. We look forward to develop-ing the enormous potential for the company’s specialist data center cool-ing systems in the UK in future.Ken Strong

Cool-Therm has been appointed as a UK distribu-

tor for Saifor, the leading data centre cooling and

technology company based in Spain.

Cool-Therm is now supplying Saifor’s full range,

which includes data centre racks, in-row coolers,

hot and cold aisle containment, intelligent Power

Distribution Units and monitoring systems.

Energy efficiency is a key design priority for Saifor,

and systems are equipped with EC fans and the

latest inverter technology.

Cool-Therm reports that it already has enquiries

from high profile clients in the UK looking for high

efficiency cooling solutions for new data centre

projects.

Saifor’s hot and cold aisle containment solution

is highly regarded, and equipped with transparent

overhead panels to enable full lighting with access

doors at each end of the aisle that open and close

automatically.

The high-tech systems can be fitted with finger-

print recognition entry for extra security.

Aisle containment is seen as a more efficient

approach than conventional up-flow/down-flow

cooling systems, as cooling is applied directly to

the heat source rather than the entire data centre

environment.

Saifor is also a leader in modular raised floor

systems, which on bespoke projects can have floor

void heights of up to 2m, giving engineers full

height access beneath server floors.

The latest generation of the award-winning,

ultra-efficient Turbomiser chiller was exhibited by

Cool-Therm at the Healthcare Estates Exhibition

and Conference in Manchester, 1-2 November.

The Turbomiser III chiller uses a new kind of

adiabatic technology that, when combined with

its high efficiency Turbocor compressors, EC fans

and Liquid Pressure Amplification (LPA) system,

delivers energy savings of more than 50 per cent

compared with conventional screw and reciprocat-

ing chillers.

The Turbomiser III is equipped with an innova-

tive evaporative system on the face of condens-

ers coils. This “adiabatic advantage” effectively

reduces ambient temperatures in the immediate

vicinity of coils by up to 8deg C, lowering condens-

ing temperatures and dramatically improving the

chiller’s energy performance.

The adiabatic system is fed by nebulised water,

which is absorbed by a porous natural-fibre hon-

eycomb array facing the Turbomiser’s condenser

coils.

NEWS In briefAwards success for Cool-Therm with TurbomiserCool-Therm has received two new accolades for its Turbomiser chiller in major national awards. The Turbomser chiller installation at Colt’s Powergate site was Highly Commended by the Judges in the recent H&V News Magazine Awards, and the Cooling Industry Awards 2011, held recently at the Hilton Park Lane, London. It follows the award for the ultra ef-ficient technology behind Turbomiser in the CIBSE Low Carbon Awards, held at The Grosvenor House in London last year.

New Reading appointmentCool-Therm has appointed a new service manager at its Reading (Alder-maston) branch. Andy Cresswell will spearhead the development of the company’s service operation in the South East and Lon-don areas. For more details, call Andy on 0303 030 0004.

Air con inspections launchedCool-Therm is now able to carry out air conditioning energy inspections, as re-uqired under the Energy Performance of Buildings Regulation. The mandatory checks are carried out under CIBSE Code of Practice TM44, which involves detailed on-site checks and recommendations for improving air conditioning energy performance. The company recently carried out a survey on Crosswater Estate at Dartford. For more details, call Alex Strong on 0303 030 0004.

Colt cuts energy costs by 55%

Our top 10 tips for cutting energy use

Cool-Therm engineer featured in press

Energy savings of 55 per cent have been achieved

following replacement of existing cooling plant

with new Turbomiser chillers at Colt Technology’s

West London data centre facility.

Monitoring of power consumption by the client

shows that after the installation of Turbomiser

chillers annual power consumption fell by more

than half.

Following the results, Cool-Therm is continuing

to support Colt and reports achieving even greater

power savings at other sites operated by the

company.

The results from the first phase of the project

demonstrate the exceptional performance and

efficiency of Turbomiser chillers, which run on

virtually frictionless magnetic bearings.

In addition to a significant reduction in energy

use, Colt has been able to improve reliability and

lower maintenance costs.

Colt Data Centre Services asked Cool-Therm to

Cool-Therm engineer Alistair Michie (pictured right)

has recently been featured in a number of high

profile magazine articles.

Three publications have published features about

his work as a field service, installation and commis-

sioning engineer.

His insightful reflections under the title, “A day in

the life of a Cool-Therm engineer”, have been pub-

lished in RAC Service Engineer, FM World and Maintenenace and Engineering.

He says it was the sheer variety of working as an acr engineer that attracted him to the job: “One

day, you are working on a roof-top overlooking a city centre such as Bristol or Dublin or Glasgow; the

next, you are hundreds of metres below the ground in a top security MoD installation. What other

job could provide this kind of variety?”

With energy costs rising sharply, here are our top

ten tips for reducing your cooling power costs, pro-

vided by Cool-Therm’s Rob Young and Alex Strong:

1. Reduce condensing temperature and increase

refrigerant liquid sub cooling. For every 2deg C

reduction in condensing temperature, energy

consumption is reduced by approximately 3%.

2. Make sure the refrigeration evaporating tem-

perature or chilled water temperature is as high

as possible, subject to meeting design conditions.

3. Ensure that the refrigerant charge is opti-

mised and sight glasses/liquid lines kept full.

4. Check and adjust expansion valves carefully.

5. Check regularly for blocked or obstructed

airways at air-cooled condensers.

6. Eliminate condenser air recirculation.

7. Ensure controls are correctly set to deliver

optimum compressor run sequences.

8. Check fans on evaporators are working and

air flow is not blocked.

9. Check water flow in chillers is optimised ac-

cording to site conditions.

10. Consider the use of inverters for improved

speed control for fans or compressors.

provide a turnkey package, matching the existing

data centre cooling load and maintaining cooling

to the centre at all times during the changeover.

Cool-Therm advised that operation of all six chill-

ers together would gain maximum compressor

efficiency under inverter control, at the same time

achieving maximum condenser efficiency due to

the utilisation of all heat exchanger surfaces to

reject heat.
