Colt CoolShaft is a combined smoke and climate control ventilation shaft system which cleverly uses evaporative cooling technology to provide active pre-cooling of the incoming air, without compromising the ability of the shaft system to ventilate the common area in a fire – and this with exceptionally low energy consumption
The quest for energy efficiency has led to very good insulation in residential buildings. While this is very good for the environment and for electricity bills, it is having unintended consequences in stair lobbies, corridors and entrance halls, which can tend to get warm and stuffy.
Since CoolShaft is a combined smoke and day-to-day shaft system, our design ensures that if there is a fire there is no compromise in its ability to ventilate the common area and allow smoke to escape.While a ventilation system supplying untreated outside air is able to achieve temperatures in the corridor at typically 3-5°C above the outside ambient, a CoolShaft system is able to reduce temperatures to below the outside ambient by providing active cooling in the corridors.
Each CoolShaft system is designed for the client's indiviudal application and is sized to suit that building's heat loads
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. Here are some of the features and benefits of Coolshaft:
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.
