Cooling towers, also known as cooling towers, are frequently juxtaposed with the problem of legionella. In fact, precisely because of the special conditions that can be created inside these facilities, primarily the high water temperature and humidity, it is possible for bacteria that are harmful even to humans to thrive and spread, first and foremost legionella. That is why it is crucial to carry out proper maintenance of cooling towers and various cooling and air conditioning systems.&zw...
An evaporative condenser is a heat exchanger for condensing a natural refrigerant gas, such as ammonia, or refrigerants of the freon family using the natural principle of evaporative cooling. By taking advantage of the latent heat of evaporation of water, this principle allows heat to be subtracted from the refrigerant gas inside the heat exchanger and a small portion of the water sprayed onto the coil to evaporate. Heat exchanger Heat removal in the evaporative condenser is then accomplished...
The lifetime of any industrial equipment, be it an evaporative condenser or a cooling tower, also depends on the proper maintenance of its components. Maintenance activities This article shows the ordinary maintenance activities to carry out on a Decsa's CFR-C closed circuit evaporative condensers, made of Z-725 galvanized steel sheet, equipped with centrifugal fans, and ideal for industrial refrigeration applications. Decsa would like to remind the user that the indications given h...
Since the second half of 2020, Decsa has been involved in the supply of new evaporative condensers for Galbani, one of the largest dairy food factories in Europe, to replace existing ones in their cooling plants. The following units have been supplied: No. 3 evaporative condensers with a capacity of 1,700 kW for the Chiller Plant; No. 4 evaporative condensers with a capacity of 1,700 kW for the Clauger Plant; No. 6 heat exchanger sections for revamping other units not produced by Decs...
Decsa is pleased to present SQA, the new series of open-circuit industrial cooling towers designed to respond effectively and efficiently to the needs of the industrial market (process cooling). SQA SQA is the perfect cooling tower for the industrial market characterized by the use of water with quantities of suspended solids, such as requiring the use of extended fill packs (more space than the classic wave 12). Designed to guarantee reduced water consumption and ensure minimum environmental...
A key element in open circuit cooling towers is the thermal fill pack (also called the "fill pack"). The greater the surface area of the water that comes into contact with the airflow through the pack, the greater the efficiency in terms of heat transfer. Not only that, but the contact time also plays an important role in ensuring the high efficiency of the cooling tower. Type of fill packs in cooling towers There are two types of fill packs: film and splash. Both have the sa...
In industrial cooling towers made of galvanized steel, passivation is an electrochemical process that slows or prevents possible corrosion of the metal from which the units are made. Rust that occurs on the cooling towers during the first period of use, called "white rust", is preventable by pre-treading the metal surface of the cooling tower. Galvanized steel in industrial cooling towers In the air conditioning(HVAC) market, galvanized steel is, to date, the main mater...
Beginning in the second half of 2019, Decsa was engaged by its own pioneering oleochemical customer to design and supply new cooling towers to serve their plants. Decsa installs new cooling towers Important order for Decsa. For a major oleochemicals company in Cremona, Italy, the Italian company specializing in the manufacture and sale of cooling towers, evaporative coolers, and evaporative condensers was actively involved in the design and supply of new cooling towers to serve their plants: o...
The cooling tower is a heat dissipation system that, based on the principle of evaporative cooling, cools down water (or water and glycol) through its exchange with air. Evaporative cooling - used for some time now in the industrial and air conditioning (HVAC) market - is a simple principle. Based on the latent heat of water's evaporation, it reduces the temperature of the process water by evaporating a small part of it. For example, one can note that, through the evaporation of one kg of...
An open circuit cooling tower is a special heat exchanger where the air comes into direct contact with water to decrease the temperature of the water itself. Cooling towers are based on a natural principle that is as simple as it is effective: evaporative cooling. When air and water meet in the thermal fill pack, a small amount of water evaporates, resulting in a natural decrease in the water's temperature circulating in the cooling tower. The cooled water is then reintegrated into the industri...
