The Heller HECS20 20L Evaporative Air Cooler cools the air by passing it over water, giving a fresher, cooler breeze than a standard fan at a fraction of the running cost of an air conditioner. The large 20L tank keeps it running longer between refills, ideal for long hot days and overnight. Works best in dry heat, which suits much of inland Australia.
Features & Benefits
-
Extra-Large 20L Water Tank: The big tank keeps the cooler running for longer between refills, so it can see you through a full hot afternoon or a warm night without topping up.
-
Evaporative Cooling: Warm air is drawn over water, which evaporates and pulls heat out of the air, so the breeze feels noticeably cooler than a regular fan.
-
Low Running Costs: An evaporative cooler uses far less power than a refrigerated air conditioner, so you can stay comfortable through summer without a big power bill.
-
Best in Dry Heat: Evaporative cooling performs best in dry conditions, which suits much of inland and southern Australia. In very humid weather, the cooling effect is reduced.
-
Fresh Air Feel: Unlike an air conditioner, it adds a little moisture back into dry air, which many people find more comfortable on hot, dry days.
-
No Installation Needed: Fill the tank, plug it in and switch it on, with no outdoor unit, ducting or installer required, which suits renters too.
