[0002] Low-resistance PVC packing is a core component of industrial cooling systems. Its design optimization and material properties directly affect the energy efficiency and operating costs of cooling towers. Through collaborative innovation in materials science and fluid mechanics, low-resistance PVC packing has become a core component for energy conservation and carbon reduction in the industrial cooling field. Driven by both intelligent manufacturing and environmental regulations, its technological iteration will be further accelerated, providing key support for the green transformation of energy-intensive industries.
