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 allows us to work today with approaches close to 2K and therefore to obtain from the cooling towers at open circuit of the cooled water outlet temperatures closer and closer to the reference wet-bulb temperature values.
The cooling towers Decsa open doors, 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 reduced operating and transport 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.
Cooling towers open circuit TMR series are equipped with double inlet centrifugal fans that ensure minimum noise and maximum reliability at the same time. Designed to best meet the system solutions where they are required cooling towers Highly performing and at the same time low operating cost, the TMR series is ideal for the cooling of process water in the civil and industrial sectors, particularly in contexts where a low level of noise emission is 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.
