Sealing system DRO

Features Packing rings (self-adjusting) with permanent spring-action for optimal, continuous contact with the seal disc, optical wear indicator Can be pressurized with buffer gas Optional dust extraction at the expansion joint Optional flush fitting to remove dust deposits at the seal disc Double-acting seal rings for use with process-compatible barrier gas or to drain toxic or aggressive gas Cutting-edge materials, supports broad range of applications Advantages Reduced pollution emissions Clean residue combustion No partial temperature reduction below the residue combustion threshold due to air infiltration (no dioxin formation) Safe operation Significant reduction in primary energy consumption Long service life, low wear Predictable downtime (e.g. annual inspection) Available as retrofit on existing systems Operating range Diameter: d1 = 2,000… 8,000 mm (78“ … 315“) Pressure: p = -50 … +250 mbar (-0,72 … 3,62 PSI) Temperature (oven surface): t = max. 300 °C (572 °F) Rotational speed: … 2.5 m/s (8.2 ft/s) Radial movement capability: … 35 mm (1,38“)* Axial movement capability: … 150 mm (5,91“)* * Greater values on request Materials Metal parts: Steel S235JR (St 37-2 / 1.0037), CrNiMo steel (1.4571) Other materials on request.
