CoolStream N natural cooling and ventilation system

CoolStream N provides low-cost evaporative / adiabatic cooling and ventilation principally for larger industrial premises with relatively high internal heat loads. It has been hygienically tested and certified to VDI 6022.

The CoolStream N evaporative 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.

Features and benefits

  • Low running costs: a huge potential geometric face area (maximum of 20 m2 per unit) and high aerodynamic efficiency allow a large amount of air to pass through one unit to cool the low-level working areas.
  • Modular design for easy installation which can fit into almost every type of wall.
  • Option of virtually silent EC fans to boost air flow and cooling capacity.
  • Simple and reliable technology – thus low maintenance costs
  • Durable: with a corrosion-resistant aluminium casing. All components that come into contact with water are powder coated.
  • High air quality: uses 100% outside air for cooling.
  • No refrigerants (e.g. CFCs) used for cooling which would be harmful to the environment.
  • Extensively tested hygienically in compliance with VDI 6022 (“Hygienic Requirements for Ventilation Systems and Units for Internal Spaces”). This is a rigorous standard for air conditioning systems and confirms the high quality of supply air.
  • Digital control with master/slave operation, standalone operation and optional bus protocol (Modbus). Option for fully automatic control, comfortable control of room temperature and touch screen operation for up to 16 CoolStream N units in conjunction with exhaust ventilators or integration into a higher-level control system.
  • Designed and manufactured by Colt.

Cooling and ventilation within one system

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.

Installation

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.

Modular design – flexibility in design and installation

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.

Fan supported

If additional airflow is required, as an option CoolStream N units can be equipped with high-energy efficiency EC fans which provide the airflow the room needs. They operate independently from the conditions outside and operating at full variable speed, providing just the right amount of airflow.
