DATA SHEET | SHAFT SYSTEM COOLSHAFT Colt CoolShaft is a combined smoke and dayto-day shaft ventilation system which uses evaporative cooling technology to provide active pre-cooling of the incoming air. This is achieved without compromising the ability of the shaft system to ventilate the common areas in a fire – and with exceptionally low energy consumption. Its features and benefits are described overleaf. PRODUCT DATA SHEET | COOLSHAFT

PRODUCT DATA SHEET | COOLSHAFT FEATURES AND BENEFITS It doesn’t need to cost the earth to cool a building: using the cooling power of water, it’s possible to achieve low energy cooling. Cooling of corridors. Whereas basic day-to-day ventilation systems for common corridors and lobbies use outside air to ventilate the space, the CoolShaft provides active cooling of incoming air, providing highly desirable conditions for the residents. If the ambient air is 30°C or above, the supply air can be cooled down adiabatically by at least 10°C. In general, the hotter the weather, the more efficient the...
