Key Challenges & Drivers Impacting the Data Centre Industry
• Reliability/Uptime
• SLA’s
• Contamination
• Energy Costs
• Carbon Emissions
• Modularity
Air Contamination
Infrastructure
•
Power Supplies
• Data Centre size is often restricted by availability of power to site.
• By reducing cooling power consumption, more power becomes
available for critical processes and server operations.

Three Modes of Operation
• Mode 1
– Cold Ambient
– Operation:- DRY MODE
– Air to Air Heat exchanger only
• Mode 2
– Warm Ambient
– Operation:- EVAP MODE
– Indirect Evaporative Cooling only
• Mode 3
– Very Warm/Hot Ambient (above approx 22°C WB)
– Operation:- EVAP + DX MODE
– Indirect Evaporative Air Cooling only + DX Cooling circuit

Legionella Risk Analysis
• The Risk Assessment of the OASIS unit
confirms that the risks of causing growth and
spread of Legionella bacteria are negligible.
• If the temperature is below 25°C, no risk of
occurrence of Legionella in the system,
which is the case most of the time.
• In the operating conditions for water above
25°C, the system is designed so that water
flows continuously in the circuit so that there
is no stagnation of water and no risk of
emergence of bacteria.
• The Oasis IEC has an automatic emptying
system that starts if installation is at standstill
for agreed hours. Therefore no risk of
proliferation of legionella in the water
recovery pan.

With free cooling system: dust & pollution from surrounding farmland caused
- Frequent replacement of filters
- Required man power & frequent inspection
- Caused pressure drop & increased fan power
Solution: Munters Oasis Indirect Evaporative Cooler replaced full free cooling system
DataInn, Lithuania – Oasis IEC key to advanced cost
efficiency
“Munters cooling solutions enable us to achieve
an annual PUE of 1.3 or less, which will make us
very cost-effective and competitive in the market.
Every 0.01 reduction in our PUE represents an
energy saving of approximately 210,000 kWh in
our data centre.”
• Secure, reliable data hall climate
• Data centre air fully separated from outside air
• 65% lower energy than common free cooling
solutions
• 25% reduction in refrigeration, switchgear,
generator sets

Data Inn Development Manager Edvinas Bakanas,
says:
“The Lithuanian electric energy sector, data
communication operators and biggest banks need their
data to be safe and accessible without interruptions, as
well as cost –effective and eco friendly. The high
efficiency and innovative design were our main reasons
for choosing Munters’ Oasis™ IEC”
“The proven technology fits well with the climate
conditions in Vilnius and offers a high degree of
flexibility, operating in different cooling modes –
depending on weather conditions.”

Greg MCCulloch DigiPlex’s Chief Operating Officer:
“Driving energy efficiency in our industry is a major
focus for us and this system halves the amount of
energy used to keep our servers working at an ideal
temperature.
This not only helps save our customers thousands
of pounds in energy costs but also ensures that our
facilities are amongst the most sustainable in the
sector”
