Less weight on your column internals. Better flow. More efficient separation.
The packing media you choose directly affects how well your column performs. Heavy, poorly shaped packing creates high pressure drop, uneven liquid distribution, and excessive load on column support structures. Lightweight tower packing saddles solve all three problems at once.
PP saddles are a trusted choice for engineers and plant operators who need reliable, cost-effective packing for absorption, stripping, scrubbing, and distillation columns. Made from polypropylene, these saddle-shaped pieces offer a curved, open geometry that promotes excellent gas-liquid contact while keeping pressure drop low and flow capacity high.
We manufacture and supply PP saddles in India from our production plant in Mandsaur, Madhya Pradesh. Our lightweight tower packing saddles for chemical industries are used in acid scrubbers, cooling towers, solvent recovery columns, and effluent treatment plants across the country. We also export to international buyers who need a dependable PP saddles manufacturer with consistent quality and on-time delivery.
Each saddle is produced from virgin polypropylene resin, giving you predictable chemical resistance, consistent dimensions, and a long service life. Whether you are packing a small pilot column or a large industrial tower, we have the right size and quantity to meet your project timeline.
Lightweight tower packing saddles are randomly packed column internals shaped like a curved saddle or half-cylinder. This curved shape means each piece orients itself differently when loaded into a column, preventing pieces from nesting flat against each other. The result is a bed with high void fraction, good liquid spreading, and consistent gas flow from bottom to top.
PP saddles belong to the family of plastic tower packing solutions alongside pall rings and cascade mini rings. They are particularly well suited to applications where the process stream is corrosive, the column structure has limited load capacity, or where ease of installation and handling is a priority.
A column packed with the wrong media will never reach its design performance. Either the pressure drop will be too high, forcing you to run below design throughput, or the mass transfer efficiency will be too low, giving poor separation and product quality. In the worst cases, both problems occur together.
Lightweight saddle packing addresses this by combining open geometry with a shape that self-distributes inside the tower. This means fewer dead zones, better wetting of the packing surface, and more consistent contact between gas and liquid phases throughout the column height.
1. Significantly Lower Structural Load
Polypropylene saddles weigh far less than ceramic tower packing saddles of the same size. This reduces the total load on column internals, support rings, and the column shell itself. For older columns being revamped, switching from ceramic to PP saddles often eliminates the need for structural reinforcement, saving significant civil and mechanical modification costs.
2. Excellent Chemical Resistance
Polypropylene resists attack from most acids, alkalis, and inorganic process streams at moderate concentrations. This makes our corrosion resistant lightweight tower packing saddles supplier-recommended product the right choice for sulphuric acid scrubbers, caustic wash columns, and any tower handling chemically aggressive streams that would corrode metal or crack ceramic packing over time.
3. High Void Fraction for Low Pressure Drop
The curved saddle geometry creates a bed with approximately 90% to 93% void fraction. This high open area allows gas and liquid to flow through the column with minimal resistance. Lower pressure drop means your blowers and pumps consume less energy to maintain design flow rates, reducing your operating cost every day the column runs.
4. Good Mass Transfer Performance
The saddle shape ensures that pieces land in random orientations when loaded into the column. No two adjacent pieces sit in the same plane. This creates a tortuous flow path that forces repeated gas-liquid contact, improving absorption and stripping efficiency compared to packing types that tend to align or nest.
5. Fast and Safe Installation
PP saddles are lightweight and do not break during normal handling and loading. Workers can load a column faster with less physical effort than with ceramic alternatives. There is no risk of sharp ceramic fragments during loading, making the installation safer. Faster installation means shorter shutdown windows and quicker return to production.
6. Long Service Life in Corrosive Environments
In a well-operated column within polypropylene temperature limits, our PP saddles last 5 to 8 years in continuous service. Polypropylene does not corrode, pit, or absorb process chemicals under normal conditions. This extended service life reduces the frequency of column openings and packing replacement, which lowers both direct material costs and the indirect cost of production loss during shutdowns.
7. Cost Advantage Over Metal and Ceramic Packing
For column applications below 100 degrees C with compatible chemical streams, our durable lightweight saddle packing for industrial tower applications delivers performance comparable to stainless steel or ceramic alternatives at a fraction of the cost. This makes PP saddles the economically correct choice for a large share of industrial scrubbing and absorption duties.
Step 1: Share Your Column Details
Give us your column diameter, packed bed height, operating temperature, and the chemicals in your process stream. If you have an existing packing specification, share that with us. If you are starting from scratch, our technical team will work through the requirements with you and recommend the right saddle size and grade.
Step 2: We Confirm the Right Specification
We confirm the saddle size (25mm, 38mm, or 50mm are standard), the polypropylene grade, and the quantity you need. We also calculate the estimated bed volume and weight based on your column dimensions, so you know exactly what to order before you commit.
Step 3: Production and Quality Inspection
Saddles are injection moulded at our Mandsaur plant using virgin polypropylene resin. We do not use recycled or blended material in our standard range. Each production batch is inspected for correct dimensions, wall thickness, and surface quality before packing. Any pieces that do not meet specification are removed.
Step 4: Packing and Documentation
Finished saddles are packed in woven polypropylene bags or bulk containers. Every order includes a dimensional inspection certificate, material confirmation document confirming virgin PP grade, and a full packing list. Export orders include all required shipping and customs documentation.
Step 5: Delivery and After-Sales Support
We dispatch on the agreed timeline. After delivery, our team remains available to answer questions about column loading procedure, bed sequencing, and installation best practices. This technical support is included at no charge for every order.

Real result from a client:
An effluent treatment plant operator in Maharashtra was running a biological air stripping column with ceramic saddle packing. The column support structure was showing signs of stress from the weight of the ceramic bed, and pressure drop had increased significantly after partial packing breakage. In mid-2023, the client replaced the entire ceramic bed with our 50mm PP saddles. Structural load on the column dropped by 65%. Pressure drop across the packed bed reduced by 30%. The column has since run without issue, and the client reports no further structural concerns. Full project payback was achieved in under 6 months.
What makes us stand out:
A PP saddle is a curved, saddle-shaped piece of polypropylene used as random packing inside industrial columns and towers. Unlike cylindrical rings such as pall rings, the curved saddle shape means pieces naturally orient at different angles when loaded, preventing flat stacking and ensuring a more open, uniformly distributed bed. Compared to ceramic tower packing saddles, PP saddles are much lighter and easier to handle, while offering similar or better performance in chemical environments within polypropylene’s temperature range.
Standard sizes are 25mm, 38mm, and 50mm. The right size depends on your column diameter and process requirements. Smaller saddles offer more surface area per unit volume but create higher pressure drop. Larger saddles reduce pressure drop and increase capacity but provide less surface area. We recommend sizing based on your column diameter and mass transfer duty, and our technical team can assist with this selection.
Standard polypropylene PP saddles are rated for continuous service up to 100 degrees C. For higher temperature applications, we recommend our PVDF grade which handles up to 150 degrees C. Always confirm your peak operating temperature, including any temperature excursions during regeneration or cleaning cycles, before finalising the material selection.
Yes. Polypropylene has good resistance to most mineral acids including hydrochloric, sulphuric, and phosphoric acids at a wide range of concentrations. This makes PP saddles well suited for acid scrubbers and absorption columns in chemical plants and industrial facilities. We recommend confirming chemical compatibility for your specific acid concentration and temperature before ordering.
The high void fraction of PP saddle packing, typically 90% to 93%, means that gas and liquid pass through the bed with very little resistance. This reduces the pressure drop across the packed bed, which directly lowers the energy your fans, blowers, and pumps need to maintain design flow rates. In a column running continuously, even a modest reduction in pressure drop translates to measurable energy savings over a full year of operation.
You need the inside diameter of the column and the required packed bed height. From these two dimensions, we calculate the packed bed volume in cubic metres. We then multiply by the bulk density of the selected saddle size to give you the total weight to order. We provide this calculation free of charge as part of our pre-order technical support.
Yes, in most cases. PP saddles are a direct random packing replacement for ceramic equivalents in applications where operating temperature and chemical compatibility allow polypropylene. The main benefit of switching is the significant reduction in bed weight, which reduces structural loading on the column. Performance is comparable or better in most scrubbing and absorption duties within polypropylene service limits.
The standard method is wet loading. Fill the column with water to cushion the impact, then slowly pour the saddles in from the top. The water slows the fall and helps the saddles settle into a random, evenly distributed bed. Dry loading is also possible for smaller columns, but care should be taken to load gradually and avoid bridging near column internals or nozzles.
PP saddles have a void fraction of approximately 90% to 93% depending on size. Larger saddles tend to have slightly higher void fractions. High void fraction means more open space in the bed, which reduces pressure drop and increases the flooding capacity of the column. This is a key advantage over older packing types with lower void fractions.

In a well-operated column within polypropylene temperature and chemical limits, PP saddles typically last 5 to 8 years before replacement is needed. Service life depends on operating temperature, the chemicals in contact with the packing, and the mechanical conditions inside the column. Polypropylene does not corrode or degrade under normal process conditions, which is why long service life is achievable compared to materials that are vulnerable to chemical attack or physical wear.
