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.

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...
