Evaporative Cooler Hire

Effective air cooling for well ventilated & outdoor spaces

We have a wide range of evaporative coolers available for hire. Evaporative air coolers provide an efficient and economical method of cooling a range of spaces. Also known as a swamp cooler, these portable air cooling machines harness the natural process of evaporation to produce cool and comfortable air in warm and dry environments. Whether you want to cool your workshop, warehouse, hangar, garage, restaurant, bar or outdoor terrace, we have a suitable evaporative air cooler for your needs. They are best suited to well ventilated areas with open windows or doors. They are not suited for cooling enclosed indoor spaces like rooms in the home and office, as they could cause a buildup of moisture in the space.

We have evaporative coolers available in a range of sizes, from our small evaporative cooler for small workshops and terraces, to our large evaporative air cooler for warehouses and events. You can book an evaporative cooler hire online using our booking system or over the phone with our hire team. We also have portable air conditioners available for hire. 

What is an evaporative cooler?

An evaporative cooler is an air cooling machine with an internal water tank, a water pump, a honeycomb-shaped membrane and an internal fan. The evaporative air cooler pumps water up from its water tank, over the honeycomb membrane, whilst the internal fan draws warm air inside the unit and passes it through the wet mebrane. As the warm air passes through the membrane, moisture in the membrane naturally evaporates into the air, which reduces the temperature of the air drastically. This cooler and more humid air is then circulated into the space, providing more comfortable conditions on warm days. Please note that the internal water tank that should be topped up regularly.

Where can an evaporative air cooler be used?

Evaporative coolers are best used in well ventilated spaces, such as workshops, garages and warehouses with large open doors, or in bar and restaurant terraces. This is due to the fact that evaporative coolers add moisture to the air. So if they are used in enclosed, poorly ventilated spaces, they can cause condensation to build-up inside the space. Therefore evaporative coolers are not suitable for rooms in the home, offices and server rooms.

For the best performance, position the unit in front of a partially opened doorway or window with the conditioned air directed into the room. Have a door or window partly opened away from the air cooler to create a 'flow through' for a better cooling effect.

What is the difference between an evaporative cooler and an air conditioner?

The key difference between evaporative air coolers and air conditioners is that evaporative coolers use water and the process of evaporation to cool the air, whilst air conditioners use refrigerant gas. Evaporative coolers add moisture to the air and air conditioners remove moisture from the air. Evaporative air coolers are much cheaper to run than air conditioners, however air conditioners provide the best option for cooling enclosed spaces such rooms in homes and offices, server rooms and other areas with equipment and materials that could be damaged by a rise in humidity.

If you are looking for an air conditioner rather than an evaporative cooler, we do also have portable air conditioner hire available.
