We have a wide range of evaporative air coolers available for hire. Evaporative coolers, also referred to as swamp coolers, provide an efficient and economical method of cooling a space. They harness the natural process of evaporation to produce cool and comfortable air for warm and dry spaces. Evaporative coolers are best used in low humidity spaces. They feature an internal water tank, a water pump, a honeycob membrane and an internal fan. These machines pump water over the honeycomb membrane whilst the internal fan draws warm air inside the unit and pass it through the wet mebrane. As the air passes through, the 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 by the cooler. The cool and humid air helps to create a more comfortable environment in warm and dry spaces. Some evaporative coolers can even be used outdoors during hot and dry spells, such as our indoor & semi outdoor evaporative air cooler unit. Please note that the internal water tank that should be topped up regularly. When using one of these air coolers, the space should be well ventilated to prevent a build-up of condensation. Evaporative coolers must not be used in areas that contain delicate materials that could be affected by a rise in humidity. Whether you want to cool your home, office, shop restaurant, outdoor terrace, warehouse or workshop, we have a suitable evaporative cooler for your needs.
