Overview
The PDS-IMTP-70 is a 70 mm IMTP packing designed for large-scale towers requiring high flow capacity and minimal pressure drop. The large void fraction of 98.5% enhances vapor-liquid contact while reducing energy consumption.
This metal tower packing is built for large-column applications where low-pressure drop, higher capacity, and reliable mass transfer are important.
Large-scale random packing for high-flow capacity
As a high-performance column random packing, PDS-IMTP-70 supports vapor and liquid movement in large towers while helping maintain stable pressure drop and operating performance.

Pressure drop control in high-capacity towers
The open IMTP packing structure helps reduce pressure drop in applications with higher vapor rates and liquid loads. This can support efficient tower operation while helping manage energy consumption.
Applications
- Gas absorption: Used in absorption columns where vapor-liquid contact and mass transfer efficiency are important to process performance.
- Heavy chemical processing: Supports heavy chemical applications that require metal random packing with strength, rigidity, and material compatibility.
- Tall distillation towers: Applied in distillation columns where tower height, vapor flow, liquid distribution, and pressure drop must be evaluated together.
- High-capacity refinery systems: Suitable for refinery applications where capacity, operational reliability, and revamping goals may require larger packing pieces.
Designed for Large Tower Conditions
PDS-IMTP-70 offers a combination of high capacity, low weight, and open geometry for large-scale column service. Its shape helps create liquid-vapor contact while supporting flow through the packed bed.
Capacity, efficiency, and flow Balance
The packing was developed to support efficiency and capacity in towers where pressure drop, liquid loads, vapor flow, surface area, and void fraction are important selection factors.
Practical Benefits of PDS-IMTP-70
Key benefits include low-pressure drop, enhanced mass transfer, increased efficiency, durable metal construction, and support for high-capacity absorption and distillation applications.
Material options for process requirements
Material options include titanium, carbon steel, and other metals listed by PDS, allowing the packing to be matched to process chemistry, temperature, corrosion conditions, and strength requirements.
Comparing Random Packing Options
PDS-IMTP-70 is part of the broader metal random packing category used in absorption, distillation, and tower applications. Depending on process goals, engineers may also evaluate pall rings, Raschig ring designs, saddle shape packing, intalox metal tower packing, or structured packing.
Packing selection factors
Third-generation packing designs were introduced to overcome limitations in earlier packing categories by improving the balance of capacity, efficiency, pressure drop, and liquid-vapor contact. Final selection should consider tower diameter, packed height, liquid hold, material strength, and required efficiency and capacity.
