Evaporative Cooling Calculator

Use our handy cooling calculator to figure out ...

Please be aware, evaporative cooling calculations are approximations only.. The effectiveness of the unit also depends on heat retention properties of the space, location/placement of the unit, insulation type, window direction or sunlight infiltration. Please refer to the relevant manual and/or contact the sales team with any specific requirements around suitability.

Delta Temperature Chart

The delta temperature of the air coming from an evaporative cooler can vary depending on a number of factors including relative humidity within the space, water temperature, airflow setting and more
