Did you know that? <\/h1>\n<p>With the arrival of spring, many evaporative machines (towers, coolers and condensers) are put back into operation after weeks or months of inactivity. It is one of the <strong><em>most critical times of the year<\/em> <\/strong>for those who operate cooling systems and, often, also <em><strong>the most underestimated<\/strong><\/em>. <\/p>\n<p>During downtime, if ponds are not drained or treated properly, standing water can quickly become an <strong><em>ideal environment for bacterial growth<\/em><\/strong>. Among the most significant risks is that related to the spread of<em> <strong>legionellosis<\/strong><\/em>, carried through the evaporation of water produced by plants. <\/p>\n<h2>What happens if no action is taken?<\/h2>\n<h3>The consequences can be significant:<\/h3>\n<ul>\n<li><strong><em>reduction in the efficiency<\/em><\/strong> of heat exchange and increased energy consumption<\/li>\n<li>possible <strong><em>health risk<\/em><\/strong><\/li>\n<\/ul>\n<h3>What to do instead?<\/h3>\n<ul>\n<li><strong><em>emptying the basins<\/em><\/strong> during extended stops<\/li>\n<li><em><strong>use biocides<\/strong> <\/em>long-acting when necessary<\/li>\n<li><em><strong>run<\/strong><\/em> always a <strong><em>disinfection<\/em><\/strong> before recommissioning<\/li>\n<\/ul>\n<p>Proper water management is critical for <strong><em>efficiency<\/em><\/strong><em>, <strong>safety<\/strong> and <strong>durability of the systems<\/strong><\/em>.<\/p>\n<p>At W-Tech we address this issue in an integrated way. We not only design and manufacture heat dissipation machines, <strong><em>but we take care of every detail<\/em><\/strong> that ensures its performance over time. <\/p>\n<p>The use of <strong>Magnelis\u00ae<\/strong>, for example, is a first <em>barrier against corrosion<\/em> because of its ability to repair itself even when scratched or machined. But for us it is not an end point: it is the basis on which we build an even more complete protection system. <\/p>\n<h2>Therefore, we integrate specific solutions at the most critical points:<\/h2>\n<h3><strong>B-COAT<\/strong><\/h3>\n<p><strong>Multi-layer protection<\/strong> dedicated to the basin, the most exposed area, resistant to corrosion, impact and aggressive agents.<\/p>\n<h3><strong>W-COAT+<\/strong><\/h3>\n<p>Full <strong>anti-corrosion coating<\/strong>, applied before assembly to provide coverage in even the most difficult areas. Resistant to UV, chemicals and weathering. <\/p>\n<h3><strong>4Shield<\/strong><\/h3>\n<p><strong>Our most advanced system:<\/strong> a 4-level protection combining structural steel, Magnelis\u00ae, W-COAT+ and a final elastomeric barrier.<\/p>\n<h2>The result: structures that are more durable, reliable and protected over time.<\/h2>\n<p>We have also developed <em><strong>W-CARE<\/strong><\/em>, our dedicated <em>water treatment<\/em> system designed to help our customers maintain <strong><em>safe, efficient facilities <\/em><\/strong>e <strong><em>comply<\/em><\/strong> with current regulations.<\/p>\n<p><em>Because, after all, protecting machines always starts with the water flowing inside them.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cooling water can also do harm.
