EVAPORATIVE COOLING

THE BASIC PRINCIPLE

An air cooler cools air through evaporation.

A pump circulates water over cooling pads while a fan pulls warm outside air through those wet pads. As water evaporates, it absorbs heat from the air, producing cooler, moister air that is blown into the room.

The same natural principle creates the cooling sensation when a breeze moves across damp skin.

THE KEY ELEMENT
WET COOLING PAD

Water continuously moves through the cooling media, allowing heat to be absorbed naturally as air passes through.

WHY IT MATTERS

WHY THIS MATTERS

Understanding evaporation helps you get the best cooling performance from your air cooler.

01

Dry Air Cools Better

Evaporation works more effectively when the surrounding air has lower humidity.

02

Fresh Air Intake Matters

Air coolers perform best when fresh outside air can enter and warm indoor air can escape.

03

Clean, Wet Pads Are Essential

Cooling pads need to remain properly wet and clean so air can pass through them efficiently.

A CLOSER LOOK AT WHAT KEEPS YOU COOL.

01

Cooling Pads

Where evaporation happens. Honeycomb pads offer a larger surface area and better efficiency; wood wool pads are more economical. Both need periodic cleaning as dust and mineral deposits reduce performance.

Cooling Pads
02

Water Pump

Circulates water from the tank to the pads. If cooling drops suddenly but the fan still runs, the pump is the first thing to check.

Water Pump
04

Water Tank

Holds the water supply. Larger tanks mean fewer refills but more weight.

Water Tank
03

Fan and Motor

Moves air through the pads and into the room. Air delivery is measured in CMM (cubic metres per hour).

05

Air Throw and Swing

Determines how far and how widely cooled air reaches you. Adjustable louvers or swing features help distribute air evenly across the room.

Ice Chamber

Some models include a dedicated ice chamber to enhance cooling during extremely hot conditions.

THE HONEST ANSWER

It Depends on Your Needs.

Air coolers are ideal for hot, dry climates and open spaces.

Air conditioners are a better choice for humid regions or when you need precise temperature control.

COOLER KNOWLEDGE

COMMON MYTHS

What people often get wrong about coolers — and what actually matters.

Coolers should be used in a closed room like an AC.
“Coolers should be used in a closed room like an AC.”
THE REALITY

No. Coolers need airflow. A closed room becomes humid and cooling drops.

A bigger fan always means better cooling.
“A bigger fan always means better cooling.”
THE REALITY

Not necessarily. Air delivery (CMH), pad quality and room match matter more than fan diameter alone.

Coolers don't work at all in humidity.
“Coolers don't work at all in humidity.”
THE REALITY

They work less effectively, no, not at all. Good ventilation improves performance considerably.

Adding more ice always makes it much colder.
“Adding more ice always makes it much colder.”
THE REALITY

Ice helps, particularly in extreme dry heat, but the effect is temporary and less dramatic than most people expect.

PRACTICAL TIPS

GETTING THE BEST PERFORMANCE

Simple operating habits can make a noticeable difference to cooling, airflow and everyday reliability.

01
↗
Airflow
AIRFLOW

Keep a window or door partially open

Coolers work best when fresh air can enter the room and warm, humid air can move out.

02
↗
Fresh air
FRESH AIR

Position the cooler near a window

Place the cooler where it can draw in fresh outside air for better circulation through the room.

03
↗
Cooling pads
PAD CARE

Clean the pads regularly

Regular cleaning helps maintain airflow and allows the cooling pads to perform evaporation effectively.

04
↗
Water care
WATER CARE

Use clean water and drain the tank

Use clean water and drain the tank when the cooler will remain unused for an extended period.

05
↗
Wet cooling pads
BETTER START

Wet the pads before switching on the fan

Run the pump for a few minutes first so the pads are fully wet before the fan begins moving air.

PERFORMANCE TIP

Fully wet pads help the cooler make better use of the evaporation process.
