CoolStream A provides low-cost evaporative cooling (adiabatic cooling) and ventilation principally for larger industrial and commercial premises. It has been hygienically tested and certified to VDI 6022.
The CoolStream A evaporative cooler helps keep larger internal spaces pleasantly 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.
Cooling, ventilation and heat reclaim within one system
CoolStream A 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 A reduces heating costs
It also includes the option of heat reclaim. If there is enough heat in the building, it can provide heating via recirculation all year round. If it is cooler outside and some additional heat is needed, the fresh outdoor air is mixed with the warm air within the building. The supply air then ensures a pleasant temperature. This method of making use of the warmer air at high level reduces the heating bill considerably. Two infinitely variable actuators control the proportion of air that is recirculated.
Installation
Compared to CoolStream T, where they are on the roof, its downstream components are inside the building.
How evaporative cooling systems work
By passing warm outdoor air across a desorption medium, energy is exchanged and a significant reduction in air temperature is achieved. The warmer and drier the outdoor air, the more efficient the evaporative cooling process is.
Applications for CoolStream systems
Evaporative cooling systems provide an efficient and effective alternative to conventional air conditioning, particularly with those industrial and semi-industrial facilities which do not require an absolutely constant internal temperature at all times, and where these buildings are generally simply too large for conventional air conditioning to be cost-effective.
Energy and water efficient
Evaporative cooling systems are up to seven times more efficient than conventional air conditioning systems and infact the warmer the outside air, the more efficient the evaporative cooling process is.
Simplicity of controls
Colt Cortiva is easy to use and, most significantly, available via a tablet PC or a smart phone. It requires no special knowledge to configure the HVAC system or to make changes to the individual parameters.
Safe and environmentally friendly
Colt CoolStream evaporative cooling systems are designed to ensure optimal water quality. They have been hygienically tested and certified to VDI 6022, ensuring peace of mind that they are safe.
