CoolStream is well suited to industries such as plastics, metal, or food, and for installation in warehouses and shopping centres, or leisure and exhibition centres.
The adiabatic or evaporative air cooler CoolStream is popular with building operators and owners because of their low initial and running costs and low maintenance.
Colt Coolstream - Evaporative cooling is an efficient and effective alternative to conventional air conditioning
How Colt CoolStream evaporative cooler works
Hot dry air is drawn across wetted media, resulting in an exchange of energy and a significant reduction in the temperature of the air. The warmer the outside temperature, the more efficiently evaporative cooling works.
Efficient and Cost effective cooling
Above 30°C, the air can cool down adiabatically by at least 10°C, resulting in very efficient cooling. Evaporative cooling is 4 to 7 times more economical than conventional systems, and at a lower investment.
Evaporative cooling and ventilation in one system
Evaporative cooling involves supplying 100% fresh air and thereby maintains air quality. It is an enhanced input ventilation system, which means it can be used in spring and summer with the cooling function only being operated when conditions dictate. Heat is normally removed at high level via natural ventilators, providing a pleasant temperature at the working area.
Boost your ventilation system with CoolStream Our evaporative cooler is particularly effective in large spaces where a pure ventilation system cannot ensure a comfortable internal working climate. It is well suited for retrofit into existing ventilation systems to boost the cooling effect.
How the evaporative cooler and ventilation system Coolstream works
CoolStream evaporative cooling units consume only around only around 1kW and 50 litres of water per 10,000m³/h of supplied air, depending on the configuration chosen. Energy consumption can be further reduced with the use of EC fans.
Colt conditions for all seasons
Colt also offers an “All Seasons” option, which can provide ventilation, heat recovery and cooling throughout the year.
The Coolstream evaproative air cooling process
Coolstream has met the requirements of VDI 6022
CoolStream’s control system is designed to ensure that water circulates safely, at the correct temperature. The unique shape of the desorption medium maintains complete darkness inside the unit, keeping the water cool. The process water is refreshed to avoid the growth of bacteria. Aluminium fins prevent the incidence of sunlight and protect the desorption medium from the external environment. All this results in optimal water quality. The CoolStream system runs on water only and requires no CFC or similar refrigerants.
Cooling tailored to the building
Colt can advise on all aspects of the ventilation design.
