COOLSHAFT

Product catalog summary

Overview: Colt CoolShaft is a dual-purpose ventilation system that combines smoke control with day-to-day ventilation using evaporative cooling technology. It actively pre-cools incoming air without compromising smoke ventilation capabilities, offering low energy consumption.

System Features:

Dual Functionality: Provides both smoke control and day-to-day ventilation, enhancing corridor conditions by reducing temperatures below ambient levels.
Component Customization: Each system is tailored to the building's specific heat load, with options for G4 filters and noise attenuators.
Integrated Controls: Features a fully integrated control system with temperature sensors on each floor.

Benefits:

Energy Efficiency: Utilizes water for cooling, achieving up to 90% efficiency and significantly lower energy use compared to conventional air conditioning.
Cost-Effective: Offers cooling up to 7 times more economical than traditional systems, with lower initial costs and operational expenses.
High Cooling Capacity: Capable of cooling multiple floors or entire buildings.
Environmentally Friendly: Free from refrigerants, avoiding F-gas compliance issues.
Hygienic Operation: Certified under VDI 6022 for hygienic air quality, with a robust water quality system.
Space and Weight Efficiency: Smaller rooftop footprint and lighter than conventional systems.

Operational Mechanism: Evaporative cooling involves warm air passing through a moist desorption medium, reducing air temperature significantly. The system supplies 100% fresh air, maintaining air quality and operating the cooling function as needed based on temperature conditions.

Performance: Designed using CISBE Guide C weather data, the system maintains corridor temperatures below 28°C for 99% of the year, with optimal performance in hotter conditions unless external humidity exceeds 90% RH.

Conclusion: CoolShaft provides an efficient, economical, and environmentally friendly solution for building ventilation and cooling, ensuring comfortable conditions for residents while maintaining safety standards.

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...
