In that context, the supply chain clearly highlighted its direction: digitalization, decarbonization, data center growth, liquid cooling development, high-temperature heat pumps, water recovery, and systems increasingly managed through dynamic control logic. In Italy, the sector generates approximately \u20ac83 billion, according to an overall macroeconomic estimate, while energy demand from data centers continues to grow globally. In this scenario, <strong>a minimal margin for error becomes an operational condition<\/strong>: system performance increasingly depends on the ability of components to maintain <strong>precision, consistency of behavior, and long-term reliability.<\/strong>   <\/p>\n<h2>How operating conditions are changing in HVAC systems and data centers<\/h2>\n<p>Advanced thermal systems now operate in dynamic conditions. BEMS, sensor technology, and advanced control logic continuously regulate flow rates, temperatures, and pressures, adapting operation to demand profiles and energy availability. In data centers, the shift from air-based solutions to hybrid configurations and liquid cooling introduces circuits with dielectric fluids and more complex distribution architectures. In smart buildings, actuators perform frequent and closely spaced adjustments. In industrial environments, heat pumps recover waste heat and push processes toward higher operating thresholds. The result is tangible: <strong>more cycles over the component lifecycle, variable loads, and more pronounced thermal gradients<\/strong>, along with exposure to fluids and mixtures requiring greater design attention. Operating conditions are changing, and the role of components changes with them.      <\/p>\n<h2>What happens when a component loses precision in advanced thermal systems<\/h2>\n<p>With continuous regulation, tolerance margins become smaller. Every deviation matters. A variation in the elastic constant changes the response of a proportional valve. A dimensional deviation affects the linearity of an actuator. A material choice that is not aligned with the application context accelerates relaxation, corrosion, and chemical incompatibility in the presence of refrigerants, water-glycol mixtures, dielectric fluids, or water reuse circuits. In continuously regulated systems, even minimal variations in elastic response generate measurable deviations in performance. In advanced cooling circuits, stability of elastic forces and seal integrity become essential conditions throughout the entire lifecycle. In HVAC systems, the activation frequency of mechanical components increases. In water recovery and reuse circuits, physico-chemical conditions become more variable. Component quality directly affects <strong>response precision, efficiency, and operational continuity.<\/strong>         <\/p>\n<h2>Which characteristics ensure operational continuity in industrial components<\/h2>\n<p>For companies such as Mollificio Valli, <strong>this scenario reinforces the value of mechanical engineering and design<\/strong>. In valves, actuators, regulation units, pumps, and control subsystems, springs and precision metal components directly contribute to the quality of the final result. In regulation systems, the spring defines the response curve and supports long-term behavioral stability. Critical factors include: <strong>fatigue resistance in repeated cycles, thermal stability, and chemical compatibility<\/strong>, dimensional precision, production consistency across batches, selection of materials and treatments suited to operating conditions, and validation through durability testing and functional verification under representative real-use conditions. In systems governed by software, sensor technology, and advanced control logic, the mechanical component is expected to deliver the same level of reliability and performance consistency. The supply chain increasingly rewards suppliers capable of supporting development through data, testing, and co-engineering.     <\/p>\n<p>The transformations highlighted during MCE find a concrete synthesis in this transition: from system design to the endurance of its components. In systems that regulate everything in real time, <strong>quality is recognized in what continues to operate with the same precision, cycle after cycle.<\/strong> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The data presented during MCE \u2013 Mostra Convegno Expocomfort 2026, held at Fiera Milano Rho from March 24 to 27, provide a concrete perspective for understanding the evolution of HVAC+R systems and the water sector.
