Product catalog summary
Overview
CoolStream is an advanced evaporative cooling, ventilation, and air conditioning system designed for continuous operation throughout the year. It is particularly effective for large industrial buildings where traditional air conditioning is not economically viable. The system is environmentally friendly, using no harmful refrigerants, and is significantly more efficient than conventional systems.
Applications
CoolStream systems are ideal for industries such as plastics, metal, and food, as well as for warehouses, shopping centers, leisure, and exhibition centers.
Features and Benefits
  • Low initial and operating costs with high energy efficiency.
  • Delivers 100% fresh outdoor air in summer and comfortable warm air in winter.
  • Complies with VDI 6022 standards for hygienic ventilation systems.
  • Available in various sizes and configurations to meet different airflow and acoustic requirements.
Operating Modes
  • Summer: Provides direct evaporative cooling by drawing hot external air over a moist medium, reducing air temperature.
  • Spring and Autumn: Mixes outdoor air with warmer internal air to pre-heat supply air.
  • Winter: Combines warmer internal air with external air to minimize heating energy and reclaim heat.
Product Variants
  • CoolStream S: Offers ventilation and cooling with an integrated water quality system to prevent calcification and ensure hygiene.
  • CoolStream T: Provides ventilation, cooling, and heat reclaim, suitable for year-round use.
  • CoolStream A: Comprises evaporative cooling, mixed air, and fan modules for efficient ventilation and air recirculation.
  • CoolStream R: A complete air conditioning solution with cooling, heating, heat reclaim, air filtration, and ventilation.
Control System
The Colt Cortiva control system offers energy-efficient management of CoolStream systems, allowing for remote access and automatic troubleshooting. It is accessible via web browsers or mobile devices and continuously updated for improved functionality.
Specifications
  • Cooling and Ventilation: The systems offer cooling, outdoor air ventilation, recirculation air ventilation, warm air recirculation, heating, and exhaust ventilation control.
  • Fan and Airflow: Types include centrifugal and axial fans with varying external pressures and airflow rates. The number of fans ranges from 1 to 4 depending on the model.
  • Evaporative Cooling: Cooling capacities range from 44 to 116 kW at specified conditions. An integrated drain with a spring return is included for safety.
  • Filter Options: Filters are available in single or two-stage configurations, with classes ranging from G4 to F9 according to EN779 standards.
  • Electrical Data: Power requirements range from 0.8 to 8.5 kW, with a supply of 400V/3Ph/50Hz. Protection is rated at IP54.
  • Acoustical Data: Sound power levels vary by model, with maximum supply air sound power levels ranging from 68 to 99 dB(A).
  • Dimensions and Weight: Dimensions vary significantly across models, with weights ranging from 150 to 950 kg.
Key Features
  • Fully automatic operation with Cortiva Receiver controls.
  • Infinitely variable fan speed for noise level management.

COOLSTREAM S∙T∙A∙R-1

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

COOLSTREAM S∙T∙A∙R-2

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 the...

COOLSTREAM S∙T∙A∙R-3

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 systems...

COOLSTREAM S∙T∙A∙R-4

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 with...

COOLSTREAM S∙T∙A∙R-5

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: cooling,...

COOLSTREAM S∙T∙A∙R-6

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 are...

COOLSTREAM S∙T∙A∙R-7

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 accessible...
