Evaporative Air Coolers



Evaporative coolers offer a cost-effective & efficient way of cooling areas on hot summer days. These portable air coolers add moisture to the air to cool it and then circulate the cool air using an internal fan. Evaporative air coolers, also known as swamp coolers, are designed for use in well-ventilated indoor and semi-outdoor spaces. They can be used in the home, as well as in cafes, restaurant and bar terraces, workshops & warehouses, events, gazebos & more.

Evaporative Air Coolers

Easy to use. Cheap to run. Effective cooling machines.

We have a great range of high-quality evaporative coolers available to order online or over the phone. These machines offer a supply of cool humid air, to create a more comfortable environment on hot and dry summer days. Also known as swamp coolers, evaporative coolers add moisture to the air to drastically lower the air temperature and then circulate this cooler air using an internal fan.

These machines are simple pieces of equipment, cheap to run and offer effective cooling in a wide range of well-ventilated indoor and outdoor spaces.

Our range of air coolers includes compact domestic models, as well as commercial and industrial evaporative coolers. So whether you are looking for an air cooler for your home, workshop, warehouse, factory, restaurant terrace, bar or event, we can provide a solution.

The Honeywell ES800 is a compact portable air cooler with a 7 litre water tank, ice compartment and sleek design. It is designed for use in the home and is suitable for areas up to 12m². Larger models, such as the Master BC60 Bio Cooler, can be used in commercial spaces such as bar and restaurant terraces, workshops, garages and more, to keep customers and workers cool on hot summer days. Whilst industrial swamp coolers such as the Broughton Comcool 52 or the Master BC 221 can be used in large industrial spaces such as warehouses, factories and depots with large open shutter doors.

How Do Evaporative Coolers Work?

Evaporative air coolers use the natural process of evaporation to cool air and then circulate it around a space using an internal fan. They feature an internal water tank, a water pump, cooling pads, as well as the fan. They pump the water from their water tank up to the top of the unit, where it flows back down and through the cooling pads. As this happens, the internal fan draws warm air into the machine and passes it through the wet cooling pads. This causes water droplets to evaporate into the air - a process which naturally reduces the temperature of the air, making it cooler and more comfortable. The internal fan then blows this cooler air out of the front of the machine to cool the space.

Where to use an evaporative air cooler

Evaporative air coolers are best used in low-humidity well-ventilated areas. If the area is not well ventilated, condensation can often build up inside the space over time. Therefore it is best to have windows or doors open whilst using one of these machines inside a space.

Evaporative coolers can be used in homes, shops, restaurants, bars, marquees, gyms, warehouses, factories, workshops, garages and much more. They can even be used in outdoor spaces such as bar and restaurant terraces.

Where NOT to use a swamp cooler

Do not use an evaporative cooler in enclosed indoor spaces with no ventilation, as this will result in a rise in relative humidity and condensation. Never use an evaporative cooler in an area that contains sensitive equipment or materials that could be affected by a rise in humidity, such as server rooms. Air conditioners offer the best option for cooling those areas.

Evaporative Coolers v Air Conditioners

Evaporative coolers are designed for use in well-ventilated indoor or semi outdoor spaces. Whilst air conditioners are designed for enclosed indoor spaces, with just a window cracked open to vent out the warm air exhaust.

This means that evaporative coolers are suitable for use on terraces and patios, as well as in spaces such as workshops, warehouses and garages with large open doors, where air conditioners would not be effective.

Evaporative air coolers only need electricity for their fan and water pump. Therefore they use significantly less power than most air conditioning systems, so they are much cheaper to run than air con units.

When cooling indoor spaces with sensitive electrical equipment or items which could be damaged by a rise in humidity - such as in galleries, museums or server rooms - air conditioners offer the best solution, as they remove moisture from the air rather than add moisture.
