The Alligator belt brush skimmer is versatile and has the ability to recover a wide range of oils not normally associated with oleophilic skimmers – from light to very viscous oil. The brush belt pulls the oil into the unit where it is elevated and recovered at the back of the skimmer with a unique double comb arrangement.

The Alligator belt brush skimmer incorporates advantages of the belt mechanism with a stiff brush that enhances the recovery of oil.

Bi-directional belt
The belt can operate in either direction. On underflow mode (with the belt going down into the oil) the skimmer can achieve a high recovery rate with lighter oils. In overflow mode (belt coming up out of the oil) the Alligator is able to recover thick layers of heavy oils with very little water – as low as 2%.

Removable floats
The floats can be detached for shipping and adjustment of skimmer depth in the water.

Removable sump
The whole sump with the DOP-160 off-loading pump attached will slide out. This is to help with transportation and provide quick access to the pump. A suction connection is fitted so that the skimmer can be used with external suction pumps and vacuum trucks. Alternative sumps are available to adapt the unit to fit onto other skimmers. The skimmer provides a lightweight package that can skim a wide range of oils not normally associated with brush skimmers. It is especially good with medium and very viscous oils. This skimmer is based on the proven belt skimmer design in a smaller and user-friendly format. It can operate effectively in open or inshore waters.

Advantages of the Alligator belt brush skimmer:

  • Combined belt-brush skimmer
  • Wide operational range especially with medium and heavy oils.
  • The belt lifts the oil and dumps into the sump
  • Optional DOP-160 vertical screw pump
  • Optional thrusters for remote control and positioning
  • Optional steam and water injection to aid pumping of heavy oils
  • Unique bi-directional operation for recovery of a wide range of oils
  • Marine grade aluminium body with detachable floats and sump

The Alligator and Armadillo belt brush skimmers have a bi-directional belt. The Armadillo is a BELT skimmer designed to be used as an independent skimmer, whilst the Alligator is a belt brush skimmer. However, both work on a similar principle for recovery.
