How an Evaporative Cooler Works?
Look! It useswater not CFCs
Hot air is drawnthrough pads andheat evaporated off
Cool filtered aircontinually flows,without recirculation
As warm air passes over wet filter pads water naturally evaporates into the air.The air is cooled as it gives up the heat required to evaporate the water.

Principle of Evaporative Cooling
Cooling is provide by Evaporative heat
exchange which takes advantage of the
principles of the latent heat of evaporation
where tremendous heat is exchanged
when water evaporates. It makes use of
the free latent energy in the atmosphere.
Energy Saving
No harmful refrigerants are used just the
natural process of evaporation to provide
the cooling.
Unlike air conditioning evaporative
cooling uses clean fresh air, allowing
odours and bacteria to be expelled
naturally through the ventilation system
without being re-circulated.
Balanced Ventilation System
When Evaporative cooling is used as part
of a balanced ventilation system to cool a
building, this allows the exterior air to be
used most of the time, making the most
use of free cooling when available,
therefore minimising costs and using
natural resources.
On the hottest day in the Summer up to
22°C of cooling can be achieved through
this process, thus providing excellent
comfort cooling for most building
requirements.
Mechanics of Unit
Water is brought into the cooler from the
mains water supply and is pumped up to
the top of the unit using a circulation
pump. The water is then dispersed over
the Cooling pads using a water
distribution system which allows the
water to flow continually over the pad.
Cooling pads
The pads become saturated, air is drawn
through the pads and the water
evaporates causing the air to cool. The
cool air is then ducted round the building
to provide cooling by means of an axial
fan. hot air in cool air out - evaporative
cooling from NE Cooler.

quality of cooled air, alleviatesthe workspace temperature,increasing worker efficiency

As ambient temperature rises, energy consumption increases, efficiency decreases
Can guarantee a fixed temperature
Can only operate well in a closed environment
Re-circulates approximately 80 ¨C 85% internal stale air
Dehydrates the atmosphere within the working environment
Does not filter any air, leaves dust, minerals and bacteria in the air-stream
As ambient temperature rises, energy consumption remains constant, efficiency increases
Temperature dependant upon ambient conditions
Needs to operate with ventilation, open environment
Operates with 100% fresh air, no re-circulation
Slightly increases humidity level in the working environment
Some filtration of air, removes dust, minerals and bacteria from the air-stream

NE Air-cooler Uses Various Type of Applications
NE Evaporative Coolers can reduce the electricity usage and carbon impact of server room and data centre cooling systems by over 90%
Computer Room Air Conditioners (CRACs) are use arefrigeration system to cool air and pass it to the void under theraised floor.
NE Air-Cooler takes external air and passes it to the void underthe raised floor. Below 18ºC ambient air is taken and mixedwith air re-circulated from the hot aisle. Above 21ºC theNE Air-Cooler uses evaporative cooling to provide air which neverexceeds 22ºC.
