9. Energy Efficiency:
Sustainable Energy Solutions.
Designing new technologies and
maximising existing ones to
ensure all new homes have a
zero carbon rating by 2016.

dilapidated hospital site in
Colindale, North London.

10. Energy Efficiency: ESCO’s
responsibility for the systems next 20-25 years operation
“The EnwaMatic is always preferred for our District Heating Networks as we achieve
consistent water quality with filtration down to 5 Microns which is essential with heat
interface units using plate heat exchangers with very small waterways. Visual
indication of the water turbidity through the flow meter sight glass confirms how
well the units operate.”

11. Chalvey, Carbon ZERO, EM 825,
18 mths operation - Excellent water chemistry.
Ian Marchant, chief
executive of Scottish
and Southern Energy,
said: “This is an exciting
project as it will give us a
much clearer picture of the
zero carbon home process
from start to finish.
“Homes in the UK account for more than a quarter of the UK’s carbon dioxide
emissions so saving energy makes sense for the planet as well as the householders.

13. Energy Efficiency:
System very heavily contaminated.
Installation of EM; Intensive backwash regime.
Operating 4 x 2MW Chillers to maintain cooling, running at full capacity.
Extra strain/wear on all components running at 100 %.
Post clean up/stabilisation: Same environmental conditions.
Same level of cooling achieved with 3 x 2 MW chillers.
Saving 2 MW.

14. Engine Cooling: EMM
Wärtsilä, Finish Ship Engine Manufacturer, recently approved EMM after
an extensive trial, 16 378 hours. Even with considerable water exchange
EMM showed satisfactory performance.
Piston thermal stress analysis by Pistons need to be constantly cooled.
Technomot Limited.
Heat needs to be ejected.
Heat stress impacts greatly on piston
lifespan.
Good water quality & chemistry impacts
positively on:
Engine optimisation
Reduced fuel consumption
Guaranteed design efficiencies.

15. Energy Efficiency:
Aberdeen City Council ↓↓ ~ 8%
Comprehensive data set, monitored by
ACC.
Marie Porteous, Energy Manager.
Comparison 20 sites vs 5 treated sites.
Registered < 5 % in some cases, upto
13 %. Av, 8 %.
Further savings achieved in second
year due to boiler output reduction.
Call outs ceased, no more blocked
components; TRV’s and strainers.

16. Energy Efficiency:
Steen & Strom, Olso, Norway, 2002:
“Before the installation the water had a return temperature of 8 °C and a
flow from the chiller of 6 °C. After the ‘clean up’ the return is 11°C and a
flow of 6°C. We have regained the design efficiency of the system”, says
Las Ørmen.
The only change to system was the introduction of EM to the CHW system.
Change in energy consumption attributed to EM.
Before installation Delta T of 2 °C. After
installation Delta T 5 °C.
Extrapolated savings
2,100 NOK = £182 per day.
Energy price 0,20 NOK (1.7 pence) per kWh,
ROI, 29 working days based on standard operation.
Year one 375,000 NOK = £32,600 per year.

17. By cleaning the blocked cooling coils of deposited debris and
corrosion by-products, the client was able to re-establish effective
cooling. The pumping requirements were reduced from four to
two 18.5 kW pumps creating considerable savings.
