What should data centre managers
and engineers be considering when
designing cooling systems?
• Airside Economisers with Heat Wheels
• Heat Pipes
Looking at the APAC, Middle East and
India regions, what challenges does
the industry face in terms of cooling?
When designing cooling systems, the data
centre managers and engineers should
first consider what type of technology they
desire. If they are interested in energy
efficient cooling products and opt for
evaporative cooling, for example, they then
have two options available, indirect or direct.
Indirect is highly suited to areas where
there are external influences and
contaminants such as air pollution from
airports, crops, smog, insects and industrial
emissions are a cause for concern. The
indirect solution keeps the air on a
closed loop and will never mix with these
potentially damaging factors.
With indirect evaporative cooling, a
secondary (scavenger) air stream is cooled
by water. The cooled secondary air stream
goes through a heat exchanger, where it
cools the primary air stream. The cooled
primary air stream is circulated by a blower.
The Oasis offers a low energy cooling
solution using indirect evaporative cooling
technology, scalable for future growth
whilst tackling tropical and hot climates,
local air pollution, multi-storey data halls
and meeting shipping requirements.
With savings of up to 75% energy costs
compared to water cooled chillers with
CRAH’s this is a truly energy efficient
solution also leading to massive savings in
infrastructure and space.
How can software and big data
support financial and energy savings
in data centre cooling?
There are software applications that can
assist with the monitoring of power and
cooling. Munters can assist with sourcing the
right type for the customer.
Can you describe the range of
solutions you offer for data centres?
Munters is proud to offer a range for indirect
and direct evaporative cooling solutions
tailored to the data centre industry that
are configurable and designed to shipping
standards. In addition, we can provide

dehumidification and humidification plus
a range of service packages. Our flagship
Oasis® Indirect Evaporative Cooler has
configurations for all regions; for example, the
Middle East region would use the Oasis DCiE
model for cooling in extreme heat conditions.
Indirect Evaporative Solutions:
• Oasis Indirect Evaporative Coolers
Direct Evaporative Solutions:
• Evaporative Pads – GlasDek,
CellDek, DataDek
• FA6 – standard ‘Wet Sections’
• WetDek – customised ‘Wet Sections’
• Standalone Humimax evaporative coolers
• Custom, large scale AHU Airside
Economisers
Make-up Air Solutions (MUA)
• Modular MUA’s, controlling humidity
and filtration
Other Custom Solutions
• Fluid Coolers
The challenges faced are a combination of
land availability, air pollution, outside air
temperature and choice of cooling solutions.
The data centres priorities also tend to
be energy efficiency; availability (power
connectivity and uptime) and total cost,
following on are M&E capacity, security
and control. Other factors are dealing with
humidity and tropical climates, air pollution
and the ability to increase scalability ranging
from modular to hyper scale data centres.
Munters’ Oasis™ product range has the
ability to satisfy all of these concerns. The
configurable system is not only energy
efficient but it can be applied to most
installation types including multi-level high
rise buildings for built up areas and deal with
extreme outside temperatures.
The Oasis™ DCiE Indirect Evaporative
Cooling system uses Munters Advanced
patented EPX technology, high efficiency fan
walls and re-claimed water keeping down the
overall costs of running a data centre.
When would I use the energy
efficient Indirect or Direct
Evaporative Cooling?
The choice of direct or indirect air
economisation for a data centre depends on
their benefits, geographic location, capital
costs, operating costs, and availability risks.
The main barrier to using direct fresh air
is the concern of air pollution and high
humidity risks on server longevity, which is
the biggest difference compared to indirect
air economiser systems, so if you are in a
high pollutant area such as a city or near to
an airport or crop farming location you are
most likely to choose a solution that does
not allow dust and contaminants into the
data hall and are noticing a trend for the
indirect solution in the majority of instances.
Cooling demands will always include
cost effectiveness, flexibility, reliability,
sustainability and design which Munters
continues to develop and optimise. n
