Unmatched reliability and outstanding performance



Evaporative air conditioning has widespread cooling applications both as stand-alone cooling or combined with selected heating technologies, to deliver an extremely efficient HVAC solution for large open spaces. It provides an ideal solution for the following applications, particularly where regular air changes are a requirement:

  • Commercial / Industrial / Manufacturing
  • Educational Facilities
  • Warehouse / Distribution / Storage
  • Athletic and Recreational Centers
  • Plant Propagation / Greenhouses

Evaporative air conditioning uses evaporation to cool the air. In an evaporative cooler, a pump circulates water from the reservoir on to a cooling pad, which in turn becomes very wet. A fan draws air from outside the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation.

The key to effective evaporative cooling is to ensure that each of the cooling pads are completely saturated at all times of operation and that the system’s fan & motor are sized and designed to deliver the appropriate airflow for the space. Cooled air inside the building is not recirculated, so doors and windows must be open for air to escape, unless a mechanical extraction is installed, providing the enclosed environment with a complete air change at least every two minutes.

All Seeley International units feature advanced technology and a range of clever design features that combine to achieve the highest cooling performance of any comparable air conditioner.


  • Energy efficient operation, up to 80% more economical than refrigerated systems
  • Delivers fresh air requirements
  • Low Cost
  • Low maintenance and ease of service requirement
  • Ideal for open and semi-open spaces
  • Effective cooling when doors and windows are frequently opening
  • Eco-friendly


Compared to other climate control systems available, evaporative air cooling provides the most energy efficient temperature relief for commercial or industrial environments of any scale.

Up to 80% more economical than conventional air conditioning systems, our evaporative cooling systems have delivered proved cost reductions and operational returns throughout many industries.

A process which occurs naturally through evaporation. Unlike air conditioning that use re-circulated air, evaporation systems circulate fresh air through a building and force out the stale hot air. The fresh air from outside is cooled by passing it over water and is then directed around the building by a fan, allowing doors to be open.
