This technique is as simple as it is environmentally friendly, and has been used around the world for decades.<\/p><p>The principle is as follows: you fill the device&rsquo;s water tank with fresh water, and plug it into the mains. The cooler then draws in hot, dry air and passes it through a moist pad. The cooled air is then redistributed inside the room.<\/p><p>This transformation process is said to be adiabatic, as it neither contributes heat nor recovers it, unlike other types of appliance such as a fan, which blows hot air.<\/p><p>The <strong>cooler<\/strong> operates via its water tank, which incorporates a submersible pump to allow water to trickle down onto the pad. It is then expelled into the room by the unit&rsquo;s fan, which generates no heat.<\/p><p>Particularly effective when outside temperatures are high and humidity low, this device can, for example, reduce the temperature by 15&deg; if the outside temperature is 36&deg;C and humidity 20&deg;C.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c7b1a50 e-flex e-con-boxed e-con e-parent\" data-id=\"c7b1a50\" data-element_type=\"container\" data-e-type=\"container\" data-settings='{\"background_background\":\"classic\"}'>\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-829623b e-con-full e-flex e-con e-child\" data-id=\"829623b\" data-element_type=\"container\" data-e-type=\"container\" data-settings='{\"background_background\":\"classic\"}'>\n\t\t\t\t<div class=\"elementor-element elementor-element-c900f21 elementor-widget__width-inherit elementor-widget-tablet__width-inherit elementor-widget elementor-widget-heading\" data-id=\"c900f21\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">A professional range to cover every need<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ba159b3 elementor-widget elementor-widget-text-editor\" data-id=\"ba159b3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>FoxAir is a specialist in <strong>mobile air coolers<\/strong>.
