Industrial Portable Air Coolers for Workspaces and Large Areas

A fan draws air through a wetted pad or similar medium; evaporation cools the passing air while adding moisture. It works best where fresh air can enter and humid air can leave.

Do not assume a single unit covers a whole building. Check the maker's stated airflow and coverage conditions, and account for ceiling height, heat sources and ventilation.

No. Evaporative cooling uses water evaporation and increases indoor moisture; air conditioning uses a refrigeration cycle and can control temperature differently. Choose for the climate and room conditions.

Prioritise airflow, stated coverage, water capacity and filling method, drainage, power requirements, noise, mobility and the need for open ventilation.
