Installed on the facade or roof, it delivers a fresh airflow at a temperature level that is unattainable for an air conditioner under these conditions.<\/p>\n\n<h4 class=\"wp-block-heading\">AD cooler principle<\/h4>\n\n<p>This performance stems from an operating principle based on an evaporative cooling system. Its cooling power is based on the energy consumed by water evaporation, the source of which is the thermal energy of the air. The hotter and drier it is, the more evaporation occurs, and the more efficient it becomes. Thus, the cooler tolerates extreme conditions. Depending on external conditions, the temperature drop varies between 7\u00b0C and 20\u00b0C. The origin of the cooling energy for an adiabatic unit is therefore primarily natural. <br\/><br\/>Consequently, it consumes ten times less electricity than an air conditioner of equivalent power. The electricity consumed comes from a fan, a water pump, a few sensors, and a remote control for distant adjustment of the unit&#8217;s airflow by varying the fan speed. Depending on their nominal airflow rates, AD coolers cool surfaces ranging from 90 to 400 m\u00b2. Beyond that, it is sufficient to distribute several units. You determine and combine the airflow rate of each unit according to the configuration of the volume to be cooled and your overall cooling needs.<\/p>\n\n<p><\/p>\n\n<h3 class=\"wp-block-heading\">IC mobile devices<\/h3>\n\n<p>These adiabatic air coolers are characterized by their flexibility and diverse uses. Usable in mobile or fixed configurations within a building, they can be installed anywhere. Furthermore, mobile coolers have a sweeping function, allowing them to temper an area without moving the unit. They can also be positioned, successively, in several locations, depending on the evolution of the heat flux impacting the work volume. <br\/><br\/>They also address emergency situations where cooling the work environment becomes mandatory. These portable versions greatly improve comfort and working conditions. Moreover, they are both ecological and economical. These units allow you to determine an airflow rate based on temperature measurement ranges in each zone of your production system, or to consider a global approach.<\/p>\n\n<p>The smallest device in the range is the IC12. It is perfect for restoring freshness to premises of 80 to 150 m\u00b2. Its counterpart, the IC 22, lowers the temperature in a factory or <a href=\"https:\/\/obera.fr\/en\/trade\/\">commercial space of 150 to 250 m\u00b2<\/a>. As for the IC 30, it is the most powerful device. It cools the air in an industrial space of 400 m\u00b2.    <\/p>\n\n<p>An air cooler offers an undeniable advantage: the hotter the air, the more significant the cooling it produces. Therefore, temperature elevation affects the airflow rate of a cooler less than that of an air conditioner.<\/p>\n\n<p>To <strong>determine the airflow rate of your industrial air cooler,<\/strong> it is important to consider the surface area of your professional premises.
