cooling for data centers"},"content":{"rendered":"<h3>Mission-critical infrastructure solution<\/h3>\n<h2>Context and challenge<\/h2>\n<p>In traditional data centers, heat dissipation is often through water-cooled chillers combined with evaporative towers or dry coolers, with a major impact on water consumption, energy consumption, operating costs and plant complexity.<\/p>\n<p>Against a backdrop of increasing focus on environmental and energy sustainability, a high-density data center operator, active in high performance computing (HPC), has embarked on a journey to optimize its cooling infrastructure, with the goal of significantly reducing combined water and energy use without compromising reliability, business continuity and performance.<\/p>\n<p>The existing configuration, based on water-cooled chillers combined with open-loop evaporative towers, was no longer fully aligned with the client&#8217;s new environmental, operational and economic goals.<\/p>\n<h2>Objectives of the project<\/h2>\n<p>Following a joint analysis, the following strategic priorities were defined:<\/p>\n<ul>\n<li>Significant reduction in water consumption while avoiding the increase in electricity consumption typical of full dry solutions<\/li>\n<li>Supporting high thermal loads in limited plant space<\/li>\n<li>Maintaining chiller architecture, improving its overall efficiency<\/li>\n<li>Guarantee of required flow temperatures in all climatic conditions<\/li>\n<li>Maximum operational reliability and service continuity<\/li>\n<li>Optimization of operation and maintenance costs in the long run<\/li>\n<\/ul>\n<h2>W-Tech analysis and proposed solution<\/h2>\n<h3>Site analysis<\/h3>\n<p>The W-Tech team conducted an in-depth analysis of the site, considering:<\/p>\n<ul>\n<li>IT load profiles and future growth scenarios<\/li>\n<li>Available spaces and layout constraints<\/li>\n<li>Energy efficiency and sustainability goals<\/li>\n<li>Local climate data, seasonality, and design conditions<\/li>\n<\/ul>\n<h3>Evaluation of cooling solutions<\/h3>\n<p>Various cooling solutions were evaluated, including traditional evaporative configurations, adiabatic systems and hybrid solutions.<\/p>\n<h3>W-Tech iSeries Solution<\/h3>\n<p>The optimal solution identified was the integration of existing chillers with W-Tech iSeries hybrid chillers, which can combine dry, adiabatic, and evaporative cooling in a single flexible and adaptive platform, dynamically optimizing the balance between energy consumption and water use.<\/p>\n<h3>Advantages of the W-Tech iSeries solution<\/h3>\n<p>The W-Tech iSeries hybrid system is designed to automatically modulate the operating mode according to outdoor environmental conditions, maximizing the overall efficiency of the chiller cooling system.<\/p>\n<h3>Key benefits<\/h3>\n<ul>\n<li>Significant reduction in water consumption compared with traditional evaporative solutions<\/li>\n<li>Significant reduction in energy consumption compared with conventional systems<\/li>\n<li>Sensible cooling guaranteed throughout the year thanks to the dry section<\/li>\n<li>Lower water use even under the most severe design conditions<\/li>\n<li>Plume elimination without the need for additional systems<\/li>\n<li>Reduction in maintenance activities and chemical use<\/li>\n<li>High operational reliability, ideal for mission-critical applications<\/li>\n<li>Small footprint, particularly suitable for sites with limited space<\/li>\n<\/ul>\n<h3>Design and maintenance<\/h3>\n<p>The crossflow design and pre-assembled delivery also ensure:<\/p>\n<ul>\n<li>Easy access to tank, batteries, and mechanical components<\/li>\n<li>Quick inspections even with units running<\/li>\n<li>Improved operational safety and reduced downtime<\/li>\n<\/ul>\n<h2>Achievements<\/h2>\n<p>Adoption of the W-Tech iSeries solution has enabled the data center to achieve concrete and measurable results:<\/p>\n<ul>\n<li>Significant improvement in annual Water Usage Effectiveness (WUE)<\/li>\n<li>Reduction of electrical power consumption by heat dissipation systems<\/li>\n<li>Important decrease in overall operating costs (energy and water)<\/li>\n<li>Improving the overall energy efficiency of the site<\/li>\n<\/ul>\n<p>The system has continuously ensured water temperatures meet the required specifications, reliably supporting high-density IT infrastructure.<\/p>\n<h2>Value to the customer<\/h2>\n<p>Thanks to the W-Tech solution, the customer was able to:<\/p>\n<ul>\n<li>Dramatically reduce water and energy consumption<\/li>\n<li>Improve data center efficiency, resilience and sustainability<\/li>\n<li>Achieve a competitive initial investment with a rapid payback compared to classical air solutions<\/li>\n<li>Align infrastructure with ESG and environmental sustainability goals<\/li>\n<\/ul>\n<h2>Why W-Tech<\/h2>\n<p>W-Tech designs and manufactures advanced cooling solutions for data centers, industry and HVAC, with a focus on:<\/p>\n<ul>\n<li>Energy Efficiency<\/li>\n<li>Reducing water consumption<\/li>\n<li>Reliability for mission-critical applications<\/li>\n<li>Customized design based on site characteristics<\/li>\n<\/ul>\n<p>W-Tech supports next-generation data centers with technologies and solutions designed to meet today&#8217;s needs and anticipate those of tomorrow.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mission-critical infrastructure solution Context and challenge In traditional data centers,
