Features:

• Venturi scrubbers are sensitive to variations in dust particulate sizes, their distribution and gas flow. With the provision to adjust the venturi throat, desired efficiency can be attained even when actual conditions differ from the design parameters at site.
• Collection efficiency of +99% is possible for dust particulate sizes of even 1 µm.
• Capacity range up to 300,000 m3/h.
• Temperature rating up to 1200 0C.
• High performance nozzles for homogenous mixing of air/liquid.
• Automated constant efficiency and constant ˆp under varying inlet flow conditions.

Hydrostatic Turbulent Contact Orifice Scrubbers:
DVTC scrubber is a pumpless wet scrubber operating under the principle of submerging the dust particulates in to the static water column by breaking the surface tension of water column through fan pressure induced turbulence at the well designed orifices. DVTC scrubber consumes very little water and the collected dust is disposed in sludge form.
Features:

• Pumpless, hence requires least plumbing maintenance.
• Collection efficiency of +90% is possible for dust particulate sizes of 10 µm.
• Modular construction.
• Capacity range up to 60,000 m3/h in single module, up to 300,000 m3/h in multiple modules.
• Temperature rating up to 70 ⁰C.
