Designed to improve the performance of cooling towers and reduce environmental impact, DecsaSpray are the next-generation nozzles developed by Decsa.
The result of an in-depth analysis of the geometries, performance and critical issues typical of traditional nozzles, the geometry of DecsaSpray was developed in cooperation with Lechler GmbH,a leading European company in spray technology.
The result is a high-performance component that combines efficiency, reliability and environmental friendliness.
The design features of DecsaSpray result in a number of operational, functional, and economic advantages that clearly distinguish it from traditional nozzles. Below are the main advantages that these new nozzles can bring to cooling towers (including those not owned by Decsa).
With the same surface area covered, fewer nozzles are required than with conventional solutions, while maintaining the effectiveness of water distribution. This is due to obtaining a wide-radius "full cone" even at low pressures.
The full-cone geometry of DecsaSpray centrifugal nozzles ensures uniform coverage over the entire surface area, exceeding the performance of ordinary hollow-cone nozzles.
Uniform water distribution is essential to avoid hot spots and maximize heat transfer efficiency.
In addition, regular distribution reduces the accumulation of sediment salts in dry areas.
A full-cone nozzle is preferred in a cooling tower to ensure even fill coverage and maximize cooling efficiency. This is especially so in systems where maintenance needs to be minimal or can be difficult.
Thanks to more efficient distribution, DecsaSpray operates at lower operating pressures, compared to using conventional rubber nozzles, reducing the power required from recirculation pumps and contributing to overall energy savings.
The absence of narrow passages within the nozzles allows even water with high suspended solids to be handled, minimizing the risk of clogging.
Nozzles consist of only two elements-body and cover-easily disassembled without specific tools, allowing quick inspections without removal from the manifold.
The need for fewer nozzles and piping allows for a 35 percent reduction in plastic materials used, contributing to Decsa's environmental sustainability goals.
DecsaSpray nozzles are available in two models, commonly identified as "small" and "large," which are chosen according to the water flow rate required by the cooling tower and the operating pressure.
Both models are made of polypropylene, a plastic material commonly used in the industry, but the design approach taken by Decsa allows fewer nozzles per unit area than traditional solutions.
This results in an overall reduction in the amount of plastic material used in plants, thus contributing to a lower environmental impact than market standards.
The design of our nozzles allows a wide range of operating pressure, enabling modulation of water flow rate without loss of efficiency.
DecsaSpray represents a perfect synthesis of technological innovation and environmental efficiency, confirming Decsa's commitment to sustainable, high-performance solutions.
Decsaspray nozzles join a range of components developed to optimize cooling tower performance, such as DecsaPack-high-efficiency thermal fill pack DecsaCoating, an advanced protective coating that provides greater durability and corrosion resistance.
