Application

Can be roof- or ground-mounted to suit site constraints.

Description

CoolStream A provides maximum design flexibility through three individual modules: the evaporative cooling module, the mixed air module, and the fan module. Similar to the CoolStream T, it blends fresh outdoor air with the warm recirculated air inside the building, ensuring effective mixing of supply air with the air just beneath the ceiling. The individual modules of a CoolStream A system can be positioned in many places, allowing maximum flexibility.

Product Highlights:

CoolStream A – Flexible Modular Cooling & Recirculation

  • Three modules: cooling, mixed air, and fan for flexibility.
  • Mixes fresh and warm ceiling air for balanced temperatures.
  • Can be roof- or ground-mounted to suit site constraints.
  • Multiple duct connection options for easy integration.
  • Compact design delivers high performance at low cost.
  • Standardised wiring simplifies installation and servicing.
  • Cortiva auto-detect speeds setup and commissioning.
  • Variable control prevents draughts while reclaiming heat.

Product Technical Information:

Connection variants:

In the classic version, the CoolStream A (cooling module) 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 is 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. Please contact our technical team to discuss your requirements further.
