Fresh-Air Cooling Systems
Evaporative Air Coolers
RTFANS industrial evaporative air coolers provide energy-efficient temperature reduction by utilizing the natural physics of water evaporation. Supplying 100% fresh, filtered, and cooled outdoor air into the building under positive pressure, these units continuously displace stale, heated air and airborne contaminants.
Key Engineering Highlights
High-efficiency 5090 / 7090 cellulose evaporative cooling media for high water evaporation efficiency
Heavy-duty UV-stabilized copolymer plastic or stainless steel weather-resistant chassis
Positive-pressure fresh-air ventilation removing indoor heat plumes, dust, and smoke
Available in top, bottom, and side discharge configurations for rooftop or wall mounting
Aerodynamic & Airflow Sizing Principles
Evaporative cooling performance is governed by local ambient dry-bulb and wet-bulb temperatures. In warm, dry, or moderately humid climates, evaporative units deliver substantial supply air temperature drops at a fraction of compressive chiller electrical demand.
