PRODUCT OVERVIEW | COOLSTREAM S∙T∙A∙R COOLSTREAM S∙T∙A∙R DESCRIPTION: CoolStream is an evaporative cooling, ventilation and air conditioning system. Its operating modes range from pure summer cooling through to all year conditioning of the internal space. APPLICATIONS: CoolStream S ∙ T ∙ A ∙ R systems are well suited to industries such as plastics, metal or food and for installation in warehouses, shopping centres, leisure and exhibition centres. FEATURES AND BENEFITS: Environmentally safe, with low initial and very low running costs (up to seven times more efficient than conventional air conditioning), CoolStream is a reliable system with good green credentials, using proven, non-complex technology. It provides 100% cool and fresh outdoor air in summer, comfortable warm air in winter and draught-free ventilation throughout the year with a high level of air quality. Technical data may be found on the back page. PRODUCT OVERVIEW | COOLSTR

PRODUCT OVERVIEW | COOLSTREAM S∙T∙A∙R DESCRIPTION Low initial, operating and maintenance costs CoolStream is an evaporative cooling and ventilation system. It is an efficient and effective alternative to conventional air conditioning, particularly in industrial buildings, where these buildings are generally simply too large for conventional air conditioning to be cost-effective. Consumption of only around 1 kW and 50 litres of water per 2.8 m3/s or 10,000m3/h of supplied air, providing up to 30kW of cooling. Refrigerant free There are no climate-damaging refrigerants such as CFCs needed for...

COOLSTREAM SOLUTIONS ARE INDIVIDUAL : Fresh air is generally always required to some extent in industry, even in the winter. Do you need as much cooling capacity as possible? Then a CoolStream S size 30 could be right for you. Do you need a quiet unit? Then a smaller and quieter CoolStream S size 12 could be the ideal choice. Colt CoolStream S∙T∙A∙R product range maintaining year-round excellent conditions The Colt Coolstream S ∙ T ∙ A ∙ R product range comprises ventilation, cooling, heating and heat reclaim systems for year-round operation. SUMMER In summer, Coolstream S ∙ T ∙ A ∙ R...

CoolStream S ventilates or cools as needed. In ventilation mode the system provides fresh outdoor air. On warmer days when pure ventilation is no longer sufficient the unit switches to evaporative cooling. The incoming air is then cooled via the process of evaporative cooling. CoolStream T ventilates or cools as needed while providing the option of heat reclaim (see p. 3, Fig.4), so (as with CoolStream A) it is suitable for use both within and outside of the cooling period. If there is enough heat in the building, it can provide heating via recirculation all year round. The system works...

Components inside the building CoolStream A consists of three modules: an evaporative cooling module, a mixed air module and fan module. Just as with the Coolstream T or R, the fresh outdoor air is mixed with the warm air within the building, so (as with CoolStream T and R) it is suitable for use both within and outside of the cooling period. If there is enough heat in the building, it can provide heating via recirculation all year round. The supply air is mixed with the air directly beneath the ceiling. CoolStream R provides a complete air conditioning solution over the entire year:...

CONFIGURATION OPTIONS | CoolStream S∙T∙A∙R A CONNECTION OPTIONS A Coolstream system is most often installed on the roof with a bottom duct connection [A]. The cooled air is supplied B into the room typically through a Coltair air inflow system. Where CoolStream units are adjacent on a building, the duct connection is usually to the side [B]. C Where CoolStream units are installed on the ground, the supply air is at first supplied upwards. In this situation a top duct connection is used [C]. HOUSING SIZES Sizes M, L or XL. XL FANS For applications with low pressure losses, quiet axial fans...

Controls options Controlling CoolStream systems with Cortiva With Colt Cortiva a new era of controls for air conditioning systems begins. Cortiva is inexpensive; it obviates the need for an external control systems integrator; and its simple routines enable it to be the solution of choice in a large number of situations. The Coolstream + Cortiva combination is unrivalled from the perspective of energy efficiency. Cortiva can finely control the CoolStream‘s continuously variable fans, resulting in savings in power consumption of up to 50 per cent. Colt Cortiva is easy to use – it’s...
