Coolstream S - Evaporative Cooling System

CoolStream S ventilates or cools on demand. In ventilation mode, it brings in fresh outdoor air. When temperatures rise, it transitions to evaporative cooling, effectively reducing air temperature through the natural process of evaporation.

Achieving up to 90% evaporative saturation with the 150 mm high-efficiency desorption medium. Water changes happen in the background, preventing calcification without interrupting cooling.

Features and benefits:

• Switches from ventilation to cooling automatically as needed.
• Uses 100% fresh outdoor air for optimum air quality.
• High-efficiency medium achieves 90% evaporative saturation.
• Automatic water change prevents scale and maintains hygiene.
• Aluminium/ stainless steel body for durability and corrosion resistance.
• Optional integrated damper prevents winter heat loss.
• Lightweight design enables easy rooftop installation.
• Eight sizes with axial or centrifugal fans for noise or power needs.

Connection Variants:

In the classic version, the CoolStream S is installed on the roof with a bottom duct connection. The cooled supply air is introduced into the room using the Coltair ventilation system. A side duct connection is typically used when the unit is installed next to a building. If the unit is placed on the floor, the supply air is first conveyed upwards. In this instance, a top duct connection is used.

Fans:

For applications with low pressure drops, particularly quiet axial fans are available, while centrifugal fans are also suitable for higher filter classes and external pressures. Only premium EC fans are used in CoolStream systems, and you can discuss exact requirements with Colt International's technical team.

Optional outdoor air filter:

The following options are available:

• Filter/ X: Without outdoor air filter.
• Filter/ A: ISO 16890 Coarse 70%.
• Filter/ B: ISO 16890 ePM10 75%.
• Filter/ C: ISO 16890 ePM1 55%.

Optional supply air damper:

With a CoolStream S, a supply air damper is available as an option. The supply air damper is either integrated into the unit or provided by the customer, with control being provided by the CoolStream S.

Performance classes:

• VDI 6022: The optional VDI 6022 package includes a sight glass, a filter gauge and LED lighting.
• IP rating and protection class: IP54 rating (to EN 60529) and Protection Class 1 (to EN 61140).

Controls:

• Colt Cortiva control: fully automatic operation for up to 16 units. Smart control via PC, laptop or tablet and smartphone.
• Colt Plexus control: With Plexus integrated into the unit and a preferred external control, you get a tailor-made control solution.

Power supply:

• Option/ EU: 380–415 V/ 50 Hz/ 3~ + N + PE.
