Coltair industrial air handling system

The Coltair industrial air handling system brings fresh outdoor air through the roof or the facade of the building. Internal air can be mixed with this outdoor air or it can be completely re-circulated, or fresh air introduced to the working area below.

Where heating is required, the supply air is reheated by an additional heating coil. Where cooling is required, this is normally achieved by combining it with a Colt Coolstream evaporative cooling system.


A flexible, high capacity air handling system which is ideal for localised cooling, heating and heat recovery, as well as for general comfort control in industrial and commercial applications. Coltair is configured from an extensive range of modular components to suit each installation.


The system is available in three standard sizes:

Size Ducting (mm)
