Metal Tellerette Ring Packing: High-Capacity Grid Design for Low ΔP & Fouling Resistance
Engineered for high-gas-load applications, Metal Tellerette Packing combines grid structure with spiral elements to maximize throughput while minimizing pressure drop and fouling. Ideal for vacuum distillation, gas scrubbing, and high-vapor-velocity systems.
| Parameter | Specification |
|---|---|
| Materials | 304/316L SS, Titanium Gr.2, Hastelloy® C-276 |
| Size Range | DN 25 (1") to DN 100 (4") |
| Surface Area | 80-180 m²/m³ |
| Void Fraction | 93-97% (industry-leading) |
| Design | Open-grid spiral + radial fins |
| Operating Temp. | -200°C to +650°C (SS316) |
| ΔP Reduction | 35% lower vs. Pall Rings |
| Flooding Point | 20% higher capacity |
| Certifications | ASTM B366, ISO 9001, PED 2014/68/EU |
1.Ultra-Low Pressure Drop
Grid-spiral hybrid design reduces gas resistance by 35% vs. ring-type packings.
2.Anti-Fouling Geometry
No internal dead zones; self-draining structure resists sludge/polymer buildup.
3.Mechanical Robustness
Laser-welded joints withstand vibration (tested to 10G acceleration).
