CoolStream S evaporative cooling and ventilation system
QA Certificate
Certificate type
CoolStream S provides low-cost adiabatic / evaporative cooling and ventilation principally for larger industrial and commercial premises.
Coolstream S units use the established principle of evaporative cooling to provide cooled air as part of a balanced ventilation system.
They are configured to integrate within the Coltair modular system of powered ventilation. They can be installed as part of a completely new scheme or retro-fitted to existing systems.
A water quality management system automatically prevents scaling and, when the cooling function is not in use, drains the cooler to prevent water stagnation.
All Coolstream units have an integrated water quality system. Water safely circulates with temperature control and regular renewal of water to avoid the growth of bacteria and scale. CoolStream has been extensively tested and certified 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.
Features and benefits:
- Evaporative cooling is up to 90% efficient.
- Option of EC fans to boost efficiency.
- Low running and maintenance costs. Only uses about 0.5 to 1 kW per 10,000 m³/h cooled air.
- Simple and reliable technology.
- Energy efficient.
- Simple to use.
- Option of two speed or variable speed controls.
- Low noise.
- High air quality: uses 100% outside air.
- Environmentally friendly and safe.
- Free from refrigerants.
- Integrated water quality control system and VDI hygiene certificate.
