Application

Evaporative (adiabatic) cooling and ventilation solutions for  larger industrial and commercial premises.

Description

Range of evaporative cooling and ventilation units for a variety of applications.


  1. CoolStream S provides low-cost evaporative cooling (adiabatic cooling) and ventilation principally for larger industrial and commercial premises.
  2. CoolStream T provides low-cost evaporative cooling (adiabatic cooling) and ventilation principally for larger industrial and commercial premises.
  3. CoolStream A provides low-cost evaporative cooling (adiabatic cooling) and ventilation principally for larger industrial and commercial premises.
  4. CoolStream R provides a complete air conditioning solution over the entire year using evaporative (adiabatic) cooling technology.


Features and benefits:

  • High evaporative cooling efficiency, low running costs.
  • Heat reclaim function reduces heating costs (CoolStream T/ A only).
  • EC fans (fitted as standard) boost efficiency.
  • Variable speed controls boost efficiency by only providing the airflow that is needed.
  • Simple and reliable technology – thus low maintenance costs.
  • All components accessible from the roof (CoolStream T/ A only).
  • Durable: corrosion-resistant aluminium housing with powder-coated water tray and water distribution system.
  • Extensively tested hygienically in compliance with VDI 6022.
  • Controlled by highly intuitive and simple Colt Cortiva controls, either through a web browser or as an app on a smart phone or tablet.
  • Additional destratification by a Colt Wastemaster system boosts the heat reclaim (not available with CoolStream S).

Colt Cortiva controller via browser or app.

Connection

Bottom duct connection.

For use when installed on to the roof.

Side duct connection.

For use when combined with alternative HVAC equipment to the standard Coltair arrangement.

Top duct connection.

For use when adjacent to a building.

System types

CoolStream A.

Highly efficient adiabatic system, using the principle of evaporative cooling to provide cooled air as part of a balanced ventilation system, in situations where conventional air conditioning is not cost-effective.

  • Uses full fresh air to maintain good air quality, with integrated water quality control system.
  • Tested to VDI 6022 with an HVAC hygiene certificate.
  • Incorporates either an AC or an EC fan.
  • Suitable for connecting to an air handling / input system such as Coltair.
