Open circuit cooling towers are cooling units that cool down a mass of industrial water to high temperatures through direct contact with air.
The encounter of sucked or pushed air with water causes partial evaporation of the same ( 3-4%) that then cools down the remaining water mass ( the latent heat of evaporation). It is sent back to the initial process to absorb heat again and start the cycle once more.
Primarily used in process cooling or air conditioning(HVAC), Decsa's open circuit cooling towers are available in TMA-EU and SQA (flow versus current) models; both are equipped with axial fans. The TMR model, on the other hand, is equipped with centrifugal fans.
All available series, made of galvanized steel sheet, are enhanced through the use of fill packs high-efficiency and balancing the L/G ratio to the best advantage.
The development of fill packs increasingly high-performance allows us to work today with approaches close to 2K and thus to obtain from the open circuit cooling cooling towers cooled water outlet temperatures increasingly close to the reference wet-bulb temperature values.
Decsa open cooling towers , ensuring efficiency and high performance, are available in a wide range of models. They are all UNI EN ISO 9001 and UNI EN IS0 14000 certified and are designed to ensure low energy and water consumption, as well as low operating and transportation costs.
Below are the main areas of application:
SQA is the new Decsa evaporative cooling tower designed to meet best the needs of the industrial market, where the use of industrial water with such quantities of suspended solids requires fill packs with larger passage spaces than traditional wave 12. Designed with the aim of guaranteeing reduced water consumption and at the same time minimising environmental impact, SQA stands out for the presence of a chimney-shape fan section- which can greatly reduce air-side pressure drops and therefore the electrical consumption of the fans.
TMR series open circuit cooling towers are equipped with dual-intake centrifugal fans that ensure both minimum noise and maximum reliability. Designed to best suit plant solutions where high-performance yet low operating cost cooling towers are required, the TMR series is ideal for process water cooling in the civil and industrial sectors, particularly in settings where low noise emission levels are required.
The TMA-EU series, certified by the Cooling Technology Institute for its thermodynamic performance, is equipped with the latest generation of axial fans and is now a benchmark in the world markets of HVAC applications for quality and reliability thanks to noise emission levels that are among the lowest in its class, low power consumption and low operating costs. The wide range of choices among the many models available makes the open circuit TMA-EU cooling tower suitable for all types of applications in cooling systems.
