Helix Brush Skimmer
Product code: DHS
Description
The Helix skimmer is a powerful brush skimmer with a revolutionary circular design to increase efficiency and total collection surface. The skimmer has a unique brush drive enabling it to collect the heaviest of oils.
Circular skimmers have some operational advantages over square or rectangular units – namely that the oil is able to flow freely onto the collection surface from any angle. This is especially important with thick and viscous oils which do not flow very easily when pumped.
- The Helix skimmer uses a new brush drive mechanism that rotates on a curved stainless steel shaft enabling the brushes to “grab” the oil from any side of the skimmer and pull it into the pump.
- Power to rotate the brushes is provided by a hydraulic motor mounted with a gearbox, ensuring the heaviest of oils can be recovered.
- The Helix brush skimmer is available supplied as a complete skimmer-head fitted with the well-proven DOP pump in various sizes. Alternatively it can be supplied as an adaptor to fit onto other skimmers.
- Its large-diameter brushes enable the Helix brush skimmer to achieve high recovery rates.
Advantages of the Helix brush skimmer:
- 360 degree oil encounter rate
- High oil recovery rate
- Drive motor fitted with gearbox for high torque
- Suitable for a wide range of oils
- Large diameter brush wheels
- Lifting point and splash cover included
- Stand-alone skimmer or adaptor for mounting on other models of weir skimmer
- Patent-pending circular brush design
