As carbon emissions continue to rise, so do the outside ambient temperatures, resulting in more and more businesses searching for cooling and ventilation solutions to protect the quality of their manufacturing processes and stock and to provide a comfortable working temperature for staff and visitors.
Evaporative Fresh-air Cooling or Adiabatic Cooling as it can often be referred to is the most efficient and effective way to cool and ventilate large open plan areas and is designed to deliver the perfect ventilation and cooling solution for large industrial and commercial spaces; such as factories, warehouses, IT data centres, medical /pharmaceutical facilities, sports and leisure facilities, large retail outlets any many more.
The ventilation based cooling also reduces the risk of Covid transmission as unlike the more traditional refrigerant air conditioning systems that use re-circulated air, evaporative cooling systems circulate 100% fresh outside air throughout a building and introduces extraction to remove warm, stale and un-hygienic air and harmful refrigerants and pollutants.
By introducing Evaporative Cooling as an integral part of a balanced Ventilation system means that the temperature of a building can be controlled even on the hottest of days.
A standard Evaporative Cooling system based on an average air flow of 12,000 m³/ hr costs only £0.142 per hour for the electricity and water consumption.
Our chosen Evaporative Cooler has 2 operational modes, pure ventilation, and cooling, with the balanced ventilation system supporting the requirements of the building and its application.
In cooler weather the units will operate in Ventilation Mode, which will be for the majority of days of the year in the UK. In this mode, the fan within the cooler is used to bring fresh air into the premises.
On warmer days, the units operate in Cooling Mode. The cooling takes place as the warm air is drawn over wetted filter pads and the water naturally evaporates into the air as it gives up the heat required to evaporate the water.
Fresh cool air is introduced into the building to cool it and the hot exhaust air is removed through open doors and windows and with the introduction of extraction fan/s to cool the building.
By using evaporative cooling as an integral part of a ventilation system means that the temperature of a building can be controlled even on the very hottest of days. In fact, the hotter the outside temperature and the lower the humidity, the greater the cooling effect.

Consumes less than 10% of the electricity of an equivalently rated refrigeration based cooling system, such as air conditioning. |
Higher electrical demand due to the refrigerant circuit compressor |
|
Ventilation only (free cooling) option for cooler days, which helps to save energy |
Energy usage is high due to the constant need for mechanical refrigeration |
|
Supplies 100% fresh cooled air |
Uses mainly recycled air |
|
Can accommodate the very hottest of days |
Performance reduces at high ambient temperatures |
|
Low carbon dioxide footprint |
Higher carbon dioxide impact |
