NE AN Series - The intelligent evaporative air cooler

The NE AN series revolutionizes the concept of fixed direct drive evaporative coolers Intelligently designed with installers and end users in mind; its ease of installation and the flexibility of its control system configuration; make it more user friendly.
Perfect suitable for Industries and Commercial Buildings.
The NE AN series has more features than any other competitive cooler. The auto drain facility, the Tornado pump, the long l i f e C o o l i n g P a d s a r e f e a t u r e s incorporated within the NE AN series Evaporative cooler.

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 mped up to the top of the unit using a circulation pump. The water is then ispersed 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.
