SDM Series Venturi Wet Scrubber
SDM-SD / SDM-ND / SDM-LD / SDM-R
Water is atomised at the venturi throat, binds the dust and is separated — over 99% capture on particles of 1 μm and above. No wear parts, no consumables, with automatic sludge scraping and a recirculation tank, plus optional screw press dewatering. Four sludge variants match different dust behaviours.
- Over 99% capture on particles ≥1 μm
- No wear parts or consumables; very low emission
- Auto sludge scraper and recirculation tank, screw press optional
- Handles aluminium, magnesium, zinc, oily, sticky and explosive dust
- Handles hot oil fume from quenching, forging and die casting
- Tank heating available for cold climates
| SDM-SD | Removable sludge bucket, low re-entrainment |
|---|---|
| SDM-ND | Hopper with gate/discharge valve for water-soluble dust and emulsion |
| SDM-LD | Full automatic scraping, continuous 2–3 shift duty |
| SDM-R | Separate nozzle, droplet separator, settling pond and fan; ponds shared by several units |
| Efficiency | Over 99% at 1 μm and coarser |
|---|---|
| Control | Valves must be set to rated air volume |
| Medium | Recirculated water |
| Heating | Tank heating for cold regions |
NRC Series Centrifugal Wet Scrubber
N RotoClone, 15,000–85,000 m³/h
A centrifugal water curtain replaces pumps and nozzles, so nothing can plug. V-type mist eliminators carry water out, the body is hot-rolled carbon steel, and the only moving parts are the fan blade and the automatic sludge remover. Efficiency is tuned by water level; wet explosion-proof operation covers aluminium, magnesium and titanium polishing.
- 15,000–85,000 m³/h dust-laden air
- Centrifugal water film — no pumps or nozzles to block
- V-type mist eliminator keeps carry-over low
- Only the fan blade and auto sludge remover move
- Three sludge options: automatic, manual, flush
- Type A water level control, no overflow; fan can top-mount
- Wet explosion-proof for aluminium, magnesium, titanium finishing
| Air volume | 15000–85000 m³/h |
|---|---|
| Principle | Centrifugal water film with V mist eliminator |
| Material | Hot-rolled carbon steel |
| Moving parts | Fan blade plus automatic sludge remover |
| Sludge | Automatic / manual / flush |
| Efficiency control | Set by water level |
| Fan position | Top-mounted option |
