Evaporative refrigeration is used in large industry sectors for its production processes and also large segments of the tertiary sector, such as the hostelry industry. The legislation points to the owner as the ultimate responsible for the proper functioning and maintenance of the equipment to avoid problems related with legionella, among other issues,  and to ensure the optimal functioning of the it and its greater energy efficiency. For this reason, the Group of Manufacturers of Evaporative Cooling Equipment of AEFYT, Association of Cold Companies and their Technologies, have developed a series of tips for the owners of cooling towers and evaporative cooling equipments. The objective is that the owners rely on a very energy efficient technology, which also has great advantages in relation to the amortization of the cost, since Legionella is perfectly controllable.
1. Know and apply Royal Decree 865/2003, of July 4, which establishes the hygienic-sanitary criteria for the prevention and control of legionellosis. Manufacturers’ maintenance recommendations take these standards as a basis, although in many cases they are extended and improved.
2. Ensure the correct operation of the equipment. Keeping the controls and periodic cleanings recommended by the manufacturers up to date. It is important to respect the periodicity of these scrupulously.
3. Take care of the design of the equipment. If the equipment is twenty years old or more it might be time to start thinking in renewing it. Currently, the design of evaporative cooling equipments includes numerous improvements designed to eliminate the conditions that favor the multiplication of bacteria, as well as to minimize the dragging of water aerosols in the air discharge of the equipment.
4. Monitor the installation site. Evaporative cooling equipment can not be placed in people’s passage areas to prevent the aerosol they emit from being inhaled. There are many doubts that the bacterium can survive several meters without the presence of a hydrological medium provided by the microdroplets, so the site is vital so that they can not be inhaled. In any case, better to prevent.
5. Ensure that maintenance control books are up-to-date and ensure that they are carried out by reputable companies. In this way, in recent years there has been an intense professionalization of the maintenance sector, as well as a greater awareness of the importance of doing a good job in this regard.
6. Legionella is fought in winter. The maintenance of a tower, although simple, is a task that must be carried out with the periodicity recommended by the manufacturer throughout the year.
Evaporative cooling equipment is suitable for almost all industrial applications where cooling is required: air conditioning for buildings, petrochemical and pharmaceutical industries, food industry, automotive industry, steel production, manufacture of electronics and semiconductor components, power plants , cogeneration plants. Without these equipments, many of the processes of these facilities could not be realized or they would do it in a much lower performance. Likewise, there would be a greater consumption of natural resources, such as water, and would supose a greater threat to the environment.
About the Group of Manufacturers of Cooling Towers of AEFYT: The Group of Manufacturers of Cooling Towers of AEFYT (Association of Cold Companies and their Technologies) is formed by companies that manufacture evaporative cooling equipment, representing 95% of the sector . These are companies committed to the development of a safe evaporative cooling technology that is beneficial for the environment and contributes to energy savings. Among the activities of the group, the diffusion of the benefits of evaporative cooling and the collaboration with the national and regional authorities in the formation of a park of modern and safe cooling towers, as well as with the rest of the interlocutors involved in its maintenance and installation.
Control y Ventilación, SL, is a company of international renown within the industrial and livestock sector, for being a manufacturer of products such as its HUMIBAT Plastic Evaporative Refrigeration, its High Efficiency Droplet Filler and Separator manufactured in High Density Polyethylene under the names of PANAL C & V and SEPARADOR C & V, or its own Cooling Towers, its NUCLEOS Towers.
