What are cooling towers? They are heat removal devices that are used to transfer process waste heat to our atmosphere. Cooling towers either use evaporation of water in order to remove process heat and cool the working fluid towards the wet bulb air temperature or if the circuit is a closed loop cooling systems, they rely on air to cool the working fluid to near the dry bulb air temperature. Common cooling tower types include cooling the the moving water used in oil refineries, petrochemical along with other chemical plants, thermal power stations and HVAC systems for cooling down buildings.
When cooling towers were first being used, they were positioned on either rooftops of buildings or as free standing structures, supplied with air from fans or natural airflow. Those who would see them would wonder, what are cooling towers doing on top of those buildings?
What are cooling towers made of? Cooling tower systems are made from corrosion proof engineered plastic material. The shell will not rust, flake, chip, peel or ever need protective coatings or paint applied. They are also made of a one piece shell, which means there are no seams, rivets, panels or an overwhelming number of fasteners to fail during use or to compromise the performance. What are cooling towers warranty? Cooling tower systems come with a 5 year warranty.
What are cooling towers purposes? Industrial cooling towers are used to remove the heat from various sources like heated process material or machinery. A dry cooling tower operates by heat transferring through surfaces that separate the working fluid from ambient air, for example in a tube to air heat exchanger, utilizing convective heat transfer.
