Description

This circular brush skimmer

The HELIX represents a significant advancement in skimmer technology. This circular brush skimmer is the result of several years of research and development.

We have overcome the challenges presented by this circular design by engineering a unique brush drive train and combing mechanisms. DESMI has recognized for some time that circular skimmers have considerable operational advantages over square or rectangular units – namely that the oil is able to flow freely onto the brushes from any angle, which is especially important with heavy and thick oils that do not flow well.

The Principle

This principle has been proven with our traditional line of self- adjusting weir skimmers. This design also significantly increases the total surface area of brushes in contact with the oil layer, in this case over 13 linear feet! The HELIX brush adaptor is available for the TERMINATOR, TERMITE as well as other weir skimmers.

The HELIX completed testing at OHMSETT under the new USCG protocol with great success! The testing included light and heavy oil in waves. Contact us if you would like a copy of the test data.

HELIX SKIMMER – A Powerful, innovative circular brush skimmer

The HELIX skimmer is a powerful brush skimmer in 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.

The HELIX is a revolutionary circular brush skimmer. It has been known for some time that 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.

DESMI Ro-Clean have invented 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 skimmer is available supplied as a complete skimmer head fitted with the well-proven DOP pump in various sizes or alternatively it can be supplied as an adaptor to fit onto other skimmers. The large diameter brushes enable the HELIX to achieve high recovery rates.

 

 

Advantages of the HELIX:

  • 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
