Product context
About Industrial Evaporative Air Cooler RTF-20 series
Industrial Evaporative Air Cooler RTF-20 series is a high-volume evaporative cooling solution for factories, warehouses and large facilities with continuous fresh-air needs. It uses wetted cooling pads and a high-volume fan to move filtered fresh air while keeping operating energy lower than conventional comfort cooling.

Operating principle
How it works
Draw in hot air
The fan or blower pulls hot outdoor air through the wet pads.
Deliver cooled air
Heat is absorbed through evaporation before filtered air reaches the occupied space.
Built for industrial use
Engineering features
High-volume fresh air
Continuous outdoor air movement helps reduce heat in open or semi-open facilities.
Efficient cooling pads
Even wetting supports stable evaporation, filtration and cooling performance.
Durable construction
Corrosion-resistant housing and reinforced components support long service life.
Simple controls
Timer, temperature and optional humidity controls make daily operation easier.

Before specifying
Operating notes
Cooling performance depends on entering air temperature, relative humidity and ventilation. The system performs best where cooled fresh air can move continuously through the space.
Service routine
Maintenance checklist
Before seasonal shutdownTurn off the water supply, empty and clean the tank, and dry the cooling pads.
During extended storageDrain circulating water and check the tank, pads and housing for scale, algae or corrosion.

RTF-20 Series Configuration Details
Review the available RTF-20 configurations, electrical options and application range.
The RTF-20 Series industrial evaporative air cooler is designed for factories, warehouses and large facilities that need continuous fresh-air cooling at practical operating cost. The series includes RTF-20A, RTF-20B and RTF-20C configurations for different electrical and installation requirements.
Water is circulated from the tank through evaporative cooling pads. A fan draws warm outdoor air through the wetted media, where evaporation absorbs heat before filtered, cooled air enters the occupied space. The system is intended for ventilated or open environments rather than sealed air-conditioned rooms.
The RTF-20 Series delivers up to 20,000 CMH airflow with approximately 1.1 kW power and an applicable area of 100~150 m², subject to the selected configuration, climate and installation layout. Confirm voltage, outlet size, water tank capacity and project heat load before final selection.
The housing, motor, cooling pads and water distribution system are designed for repeated industrial operation. The cooler can support production areas, warehouses, workshops and other facilities where fresh-air movement improves worker comfort.
Maintenance includes cleaning the tank and pads, checking water distribution, draining the system during seasonal shutdown and inspecting electrical connections, housing and fasteners. Contact RTFANS for help matching the RTF-20 configuration to the facility layout.
