Discoil, is the oil skimmer with discs that resolve various and multiple problems, even in situations with the risk of chemical corrosion (solvents, chloride), mechanical abrasion (sand, metal particles and abrasive materials) and critical temperature situations (due to the weather, cold or hot climates). The decision to diversify work, techniques and equipment is never standard but based on the needs that arise from the different types of problems. In fact, when the environment creates corrosive, abrasive and wear conditions that are the variables taken in the construction of a Discoil machine.

Oil flows into a primary collection tank (part of the machine) and then is transferred to a storage tank.

The transfer operation of the recovered product may be carried out using three main systems:

  • discharge pump
  • autoclave
  • discharge by gravity


There are different Discoil models according to:

The machine size is set by the number (from 1 to 12) and diameter (from 750 to 1200 mm) of the discs. The number and diameter of the discs determine the capacity of recovery and recall of Discoil.

Model S1 S4 M4 M6 L10 L12
Oil recovery capacity 1 m3/h 3 m3/h 10 m3/h 15 m3/h 15 m3/h 17 m3/h

Discoil materials vary according to the type of hydrocarbons to be recovered and the hostile nature of the environment where it will operate. Specifically, the machine can be constructed in painted carbon steel, stainless steel or duplex, and special attention is also devoted to rubber parts that are selected according to the application.

It is provided by a hydraulic generator which may be powered by a flameproof electric motor, or even by a diesel engine, in case of installation in a non-hazardous area.

Discoil is certified to operate in classified areas (ATEX certificate for zone 0,1 and 2).

It can be equipped with Fixed Platforms, Floating Platforms, Lifting System, or other custom structures allowing Discoil to perform routine daily operations even in hard situations.

Fixed Installation

In case the level of water is fixed, the machine is supported by a metallic structure (gratings) generally attached to the side basin walls and equipped with catwalk and service platforms to permit maintenance.

Floating Platforms

In case of variable level of water, a floating platform can be anchored by mooring cables or attached to the tank with vertically sliding guides to support the machine.

Lifting System

Normally adopted in tanks where, for space reasons, floats cannot be used, or in deep tanks or chambers where maintenance personnel access is discouraged.


Discoil can be used anywhere water needs to be treated:

  • Refineries
  • Coastal petroleum product terminals
  • Petrochemical plants
  • Steelworks (Still mill)
  • Power plants
  • Petroleum jetties and pumping stations
  • Ballast water plants
  • Mechanical industries
