✦ Swival Arm Mast MOC would be M.S. with Rustocon primer coatings and Epoxy P.U. Primer coating with 2 coats of P.U. Paint coating

✦ Main Body MOC would be Light weight engineering grade Aluminium with Epoxy painting.

✦ At the time of installation you will provide for the fabrication etc for the mounting of the skimmer mechanism at site.

✦ oil skimmer would be ready to perform continuosly for 24 hours and for 365 days a year.

✦ Suitable rain hood cover would be provided to protect the mechanism during rainy seasons if the system is to be kept in open.

✦ Imported polymer Tube is used for more tube travel life as well maximum oil removal .

✦ Tube has property of floating on top of the liquid and thus is capable of collecting maximum surface of the tank liquid.

✦We userustocon primer which is having property of forming insulation coating for rust as well converts the surface rust into protective layer and then Epoxy Polyurethane paint system which is the best possible painting scheme available today .

Below given are the typical Tube oil skimmer engineering specification for an industrial quality Tube Type Oil Skimmer with Dia. ¾”(18mm) Collector Tube and Foot Mount.

✦ GENERAL OBSERVATIONS:

‑ Tube-type oil skimmer unit shall be used and designed for the removal of free floating oils from the surface of water in a sump. The basic advantage in using Tube type oil skimmer is that the tube floats on the water and thus more free floating oil sticks to the tube and thus it is more efficient .

‑ The skimmer shall be mounted on a pre-engineered and fabricated stand that elevates the unit such that the elevation of the oil discharge pipe is approximately 1.1 Metres above the ground level so that oil can be collected in a bigger oil collection vessel kept on the ground level. An oil collection tray is provided on the stand beneath the separator to collect the free oil from the skimmer.

‑ Oil skimmer shall operate by skimming surface oils with a 18 mm diameter floating continuous loop tube. This tube is manufactured of a material that attracts free oils and grease, while being resistant to abrasion. Oil is removed from this tube as it passes through replaceable and adjustable scrapers system made of glass filled Nylon moulded material that will not crack or chip and is highly abrasive resistant.

‑ Skimmer shall operate at a fixed speed of 35 rpm , with the following minimal design removal rate:

      · Heavy oil – 50 LPH

      · Medium oil – 25 LPH

      · Light oil – 12 LPH

‑ Collector tube length is Tank Technical details dependent and is calculated based on the data provided by the customer.

The Tube floats on the surface of water and is driven in a continuous loop by the oil skimmer. Free-floating oils, fats and grease cling to the outside surface of the collector tube and are pulled into the oil skimmer where they are removed by tube scrapers. The material removed flows into a oil collection tray . The collector tube is then driven back to the water to remove more floating oil.
