CPVC Intalox Saddle Product Description

The CPVC Intalox Saddle is a high-performance random packing manufactured from chlorinated polyvinyl chloride (CPVC), a material engineered to overcome the temperature and chemical limitations of standard PVC. By increasing the chlorine content to 61%–65%, CPVC achieves a heat distortion temperature up to 105°C and significantly improved resistance to chlorine gas, sodium hypochlorite, and sodium hydroxide—making it uniquely suited to the chlor-alkali industry and other aggressive chemical services. The saddle-shaped geometry prevents interlocking and nesting, ensuring uniform bed porosity, while the arched liquid channels and internal vanes promote intimate gas-liquid contact with minimal drag. Compared to CPVC Pall rings, the Intalox Saddle delivers higher flux and lower pressure drop with comparable or better mass transfer efficiency. It is widely used in absorption, scrubbing, stripping, and cooling towers across chemical, chlor-alkali, and environmental protection industries.

Product Highlights

• Higher Temperature Rating: CPVC withstands continuous operating temperatures up to 105°C, significantly higher than standard PVC (≤60°C), making it suitable for hot chlorine gas and warm alkaline solutions.
• Superior Chlor-Alkali Resistance: Specifically resistant to chlorine gas, sodium hypochlorite, sodium hydroxide, and other aggressive chemicals encountered in chlor-alkali production, ensuring long service life.
• Higher Capacity than Pall Rings: The saddle geometry provides larger void space and a freer gas flow path, delivering higher flux and lower pressure drop than equivalent-size CPVC Pall rings.
• Anti-Nesting & Uniform Porosity: Rectangular contact surfaces at both ends prevent packing pieces from interlocking, maintaining uniform porosity throughout the bed and avoiding channeling.
• Excellent Liquid Distribution: The arched liquid channels and internal vanes promote uniform liquid spreading and high liquid holdup, ensuring good absorption efficiency even in slow chemical reactions.
• High Mechanical Strength: CPVC offers compressive strength exceeding 8.0 MPa, providing greater rigidity and load-bearing capacity than PP or PVC, preventing deformation in deep packed beds.
