Evaporative Coolers
3 industrial portable evaporative coolers from TradeQuip. 550W and 750W professional units for workshop, warehouse, transport depot and event cooling in dry inland AU climates. Lower capex + lower running cost than refrigerated portable AC.
Evap vs portable AC - humidity rule. Evaporative cooling works in dry inland AU climates (most of QLD, NSW, SA, WA, NT inland) where humidity is below 60 percent. Above 60 percent humidity, evap effectiveness drops because the air is already near-saturated with water. Portable refrigerated AC is the right pick for coastal humid AU (Brisbane, Sydney coastal, Melbourne, Perth coastal).
