Plastic Polyhedral Hollow Ball Tower Packing – High-Efficiency Mass Transfer for Global Industry

The plastic polyhedral hollow ball is a core random tower packing engineered for superior gas-liquid contact in scrubbers, cooling towers, absorption columns and stripping systems. Manufactured from high-grade polypropylene (PP), polyethylene (PE) or PVC, each ball is formed by a spherical body with multiple half-moon blades arranged around a central reinforcing ring, creating a large, turbulence-enhancing surface without excessive weight. With a typical diameter of 38 mm, the ball delivers a specific surface area of approximately 150 m²/m³, a void fraction of 0.92, and a stacking density of around 25,200 pieces per cubic metre. These precise geometric characteristics enable uniform liquid redistribution, low pressure drop and sustained performance even under high gas velocities or thermal fluctuations, making the product indispensable in petrochemical, fertilizer, steel and wastewater treatment facilities.

Driven by our in-house R&D and ISO 9001-certified production lines, we maintain strict tolerances on blade thickness and curvature to optimise film formation and mass transfer efficiency. Comparative field data show that when replacing traditional Pall rings or Raschig rings in a typical cooling tower circulation loop, polyhedral hollow balls can lift volumetric mass transfer coefficients by 12 %–18 % while reducing fan energy consumption by 5 %–8 % thanks to their lighter wet weight and lower resistance. The material’s inherent resistance to acids, alkalis and organic solvents further allows continuous operation in pH environments ranging from 2 to 14 and temperatures up to 90 °C (PP grade) or 110 °C (reinforced PE grade). All batches undergo rigorous mechanical strength, hydrolysis and UV-ageing tests to ensure a service life exceeding five years under normal chemical conditions.

In summary, plastic polyhedral hollow balls have been proven as a high-efficiency random packing widely deployed in cooling towers, absorption columns, scrubbing systems and stripping towers across petrochemical, fertilizer, steel and wastewater treatment sectors, delivering reliable low pressure drop and stable mass transfer performance under diverse pH and temperature conditions. As a factory-direct manufacturer exporting worldwide, we manufacture polyhedral hollow balls to customer-specified dimensions, and can tailor material grades — including PP, PE and PVC — to exact process specifications, ensuring optimum column fit and operational efficiency.
