Evaporative cooling systems:  Reducing greenhouse temperature in warm climates is a technical challenge that involves the evaluation of the mass and energy balances, the ventilation system, and the physiological processes inherent in the crop. The Technical Department of APR Greenhouses & Technology will study the best solution for your needs.
In facilities with processes where the environmental conditions and the safety level are decisive – such as in nurseries, experimental greenhouses, greenhouses with special crops, animal farms, cooling of large-scale working centres, etc. - advantage can be taken of the benefits offered by a reasonable investment in a unit with very good features. APR Greenhouses & Technology can offer you the working conditions best adapted to warm climates, allowing you to enlarge the production cycle, assure the viability of your crops, seedbeds and nurseries, experimentation trials, improve the staff working conditions, etc. Tell us your location and needs, and we will offer you our best proposa. Systems of evaporative cooling panels: The systems of evaporative cooling panels are systems that aim to provide the most appropriate temperature and humidity in the different premises and compartments that require conditioning, all of which is achieved by the renewing the interior air with air from outside which has had its temperature reduced and its humidity increased by means of the evaporation produced as it passes through a panel with cells of different inclination and arrangement that are highly efficient in relation with this process. The air so treated is displaced through the enclosure from its entrance to its exit, extracting the heat load and providing the temperature and humidity conditions required by the plants, animals and personnel. 
A set of evaporative panels includes: Fans: they provide the renewal of the air volume held in the room or compartment to be cooled. They are usually fans of the helical type with shutter blinds, working in extractor mode. Evaporative panel: fabricated usually with cellulose sheets folded at different angles, joined to form a panel of cells with a variable depth, depending on the requirements of the project and the performance desired from the process. Wet wall of evaporative panels: the panels used are available in different geometries, and they are installed in modules with different numbers, capable of providing sufficient surface area, and organized so their wetting with water can be carried out uniformly and at the same time address the necessary evaporation flow. The wall has a wetting channel in its top part and a drainage channel for concentrates at the bottom. Wetting installation: it consists of a tank and an electric pump, from where the necessary flow is provided to moisten the wet wall.
