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.

Portable Cooling Application Details
Review mobility, water capacity, controls and the recommended open-space applications for this portable cooler.
Portable Air Cooler KA-20 is a mobile evaporative cooling solution for workshops, warehouses, events and occupied areas that need flexible spot cooling. Its wheeled housing allows operators to move cooling toward people, machines or work zones without permanent ductwork.
Water is added to the tank and circulated through the evaporative cooling pads. The fan draws warm outdoor air through the wetted media, where evaporation absorbs heat before cooled fresh air is delivered into the open space.
The Portable Air Cooler KA-20 is designed for ventilated environments such as factories, logistics areas, workshops, farms, sports facilities and temporary event spaces. Evaporative cooling performs best when the air path remains open and warm air can leave the space.
The unit combines a protective housing, adjustable fan speed and practical operator controls. Depending on the configuration, the published specifications include 9,000 airflow, 500 rated power, 100 application area and a 55 water tank. Confirm the final electrical configuration and operating conditions before quotation.
Routine service includes checking water quality, cleaning the tank and cooling pads, inspecting the pump and confirming that the fan guard and wheels remain secure. Drain the water system during extended storage and keep the air path free from obstructions.
For project selection, confirm the required coverage, humidity conditions, refill or drainage routine and the position of workers or equipment that need targeted cooling.
