What is Evaporative Cooling?
Evaporative coolers are cooling systems that use only water and a blower (fan) to circulate air. When warm, dry air is pulled through a water soaked pad, water is evaporated and is absorbed as water vapour into the air. The air is cooled in the process and the humidity is increased.
The evaporator cooling technology is an energy-efficient alternative to compressor-based cooling. In dry evaporative cooling can meet most or all building cooling loads using one-fourth the energy of conventional equipment. It can also be applied cost effectively when integrated with conventional chiller systems, which can greatly improve a facility's load profile.

WHY CHOOSE EVAPORATIVE COOLING
Evaporative coolers do not use compressors, condenser, chiller coils, cooling towers or heavily insulated piping. Thus the cost of acquisition and operation is a fraction of conventional air conditioning and mechanical refrigeration systems.
Initial cost is less than 1/2 the cost of refrigerated air conditioning and the operating costs is less than 1/3rd the cost of refrigerated air conditioning to run. Maintenance costs are minimal requiring simpler procedures.
Evaporative air-cooling creates cooler temperatures a number of ways:
It lowers effective temperature - the temperature you feel - by at least an additional 4º to 6º. In some cases, the temperature will be lowered more, depending on relative humidity. The rapid motion of cool air increases skin surface evaporation resulting in body heat loss.
It reduces radiated heat. The constant flow of cool air absorbs heat from all exposed surfaces and results in a reduction of the heat radiated to the human body.
In a large number of industries, it is normal in hot weather to experience increased heat related illness, lower productivity and increased absenteeism among workers. Many of these industries cannot afford the tremendous costs of conventional mechanical refrigeration or air conditioning, while they can afford evaporative cooling.
Health & Environment Benefits:
Evaporative cooling is healthy and comfortable because it;
Brings 100% fresh outside air that is cooled & washed through filter pads
Comfort is improved with air movement- not stuffy & stale
Constant air movement of the evaporative cooler pushes hot air out removing dust, pollen, smoke, odour, and pollution and replaces it with cool fresh air.
Helps maintain natural humidity levels, which benefits both people and furniture and cuts static electricity.
Unlike air conditioning, evaporative cooling does not require an airtight structure to operate at maximum efficiency. In fact, the building occupants can open doors and windows.
Evaporative cooling is also an environmentally-friendly alternative to air-conditioning since it has no CFC's or HCFC's. Summarizing, the evaporative coolers have a low first cost, use a lot less electricity than conventional air-conditioners, and do not use refrigerants, such as chlorofluorocarbons (CFCs) and hydro-chlorofluorocarbons (HCFCs) that can harm the ozone layer. It is economical, effective and it provides much needed alternative to conventional mechanical refrigeration
