CoolStream N provides low-cost adiabatic / evaporative cooling and ventilation principally for larger industrial premises with relatively high internal heat loads.
The CoolStream N adiabatic cooler helps keep larger internal spaces cool all year round. It doesn’t need to cost the earth: using the cooling power of water, it’s possible to achieve low energy cooling.
Fresh outside air is drawn in as the result of the natural thermal conditions within the building and passes through a wetted desorption medium and is cooled. The supply of cooled air at low level combined with removal of heat at high level via either natural or mechanical ventilators provide a pleasant temperature at the working area.
If the thermal movement is likely to be insufficient, the unit can also be equipped with continuously variable highly efficient EC fans.
CoolStream N is well suited to industries such as power generation, plastics, metal, or food, either as a new system or an add-on to existing natural ventilation systems.
CoolStream systems are popular with building operators and owners because of their low initial and running costs and low maintenance.
We offer you the CoolStream S for when only cooling combined with natural or mechanical ventilation is required. CoolStream S uses low-energy fans to move the air.
We offer you the CoolStream R as a second alternative for the complete air conditioning of industrial, semi-industrial and commercial spaces over the entire year.
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.
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 cooling is. Evaporative cooling is up to 7 times more economical than conventional air conditioning systems, and has lower initial costs.
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. Excess heat is normally removed at high level via natural ventilators, providing a pleasant temperature in the internal space.
CoolStream N is particularly effective in large spaces where a purely natural ventilation system cannot ensure a comfortable internal working climate. It is well suited for retrofit into existing natural ventilation systems to boost the cooling effect. The natural ventilation system is supported by the cooler inlet air, so that with the same free inlet area a lower room temperature can be achieved.
CoolStream N is mounted into the façade of a building. A conventional weather louvre system is fitted onto the outside of the unit. It is only 425mm in depth, allowing installation into most kinds of buildings.
Its modular design and high degree of pre-assembly facilitate installation.
The modular system is available in 400 mm increments and up to 10 metres wide. It has four different heights between 666 mm and 2000 mm. Its largest standard geometric size is 20 m2. With only 425 mm overall depth and a wide variety of available paint finishes, the CoolStream N can be installed into most kinds of buildings.
If additional airflow is required, as an option CoolStream N units can be equipped with high-energy efficiency EC fans which provide the air flow the room needs. They operate independently from the conditions outside and operating at full variable speed, providing just the right amount of airflow.
The control system of CoolStream N is designed to ensure that water circulates safely, at the correct temperature. The process water is refreshed to avoid the growth of bacteria. The design prevents the incidence of sunlight and protects the desorption medium from the external environment. All this results in optimum water quality.
CoolStream N units have the highest degree of hygiene, with an integrated water quality control system, and they have been tested to and are in compliance with VDI 6022.
CoolStream N units consume only around only around 50 litres of water per 10,000m³/h of supplied air, and use virtually no electric power.
Colt can advise on all aspects of the ventilation design. With the help of the most advanced CFD calculations, Colt can provide support right at the start of the project and thereby provide definitive information as regards the expected performance and conditions within the conditioned space.
CoolStream needs a suitable environment for it to be able to perform correctly.
It should not:
Highly efficient evaporative cooling system for the façade. Provides cooled air as part of a balanced natural ventilation system, to keep the indoor climate cool. Uses only fresh outside air. Has an integrated water quality control system, and is fully hygienic. Can incorporate optional EC fans to boost air flow and cooling capacity if required. For combination with natural façade ventilators.
