Evaporative Cooling Installation Methods
There are two principles of installation: External and Internal
EXTERNAL INSTALLATION - - DOWN DISCHARGE
The majority of coolers are installed in this way. The extract would typically be 80% of the total cooler capacity.
Roof mounted down discharge systems are typically mounted using a soaker sheet to provide a weather proof installation.

Where ventilation exists an internal unit can be suspended from the building structure. Air can then be directed for spot cooling or diffused as part of a larger scheme. The hot, dry air is taken in and cooled air is distributed exactly where it is required. The stainless steel plenum chamber allows great flexibility in setting the direction of the air flow. |

The ECPSDU is designed to be supported from a plain square duct with nominal external dimensions 645mm x 645mm.

 Internal coolers can be mounted on pedestals to provide spot cooling |
