Product context
Grace Series is designed for large factories, warehouses and high-heat industrial spaces. Its controlled air movement helps equalize temperatures and reduce stagnant air in large occupied spaces.
Operating principle
Water is circulated from the tank to saturate the evaporative cooling pads.
The fan or blower pulls hot outdoor air through the wet pads.
Heat is absorbed through evaporation before filtered air reaches the occupied space.
Built for industrial use
Continuous outdoor air movement helps reduce heat in open or semi-open facilities.
Even wetting supports stable evaporation, filtration and cooling performance.
Corrosion-resistant housing and reinforced components support long service life.
Timer, temperature and optional humidity controls make daily operation easier.
Selection data
Before specifying
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
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.
