STEINIG-Oil Skimmer OTF-S (with disc)

Following descriped Type: OTF-1 S, OTF-2 S, OTF-3 S

 

otf s 1OTF-1 S

  • disc-Ø 200, 250, 300 and 365 mm
  • motor: 230 V, 50 Hz, 3 watt, synchron gear motor according to VDE 0530/0730, to fit according protection class I, to earth
  • with additional clamping box
  • separating between disc (water part) and unit through plastic connection
  • with integrated bonnet
  • for fast mounting
  • total made of stainless steel, wipers of PTFE adjustable
  • special design: thread nozzle R 1" AG, clamping feature, ready to fit a drain hose, level switch for oil collecting tank
Construction
Type: simple unit construction, total made of stainless steel
wiper: by hand adjustable, very immun, wear resistant
total drain: open, simple drain, against extra cost oil outlet drain with R 1″ AG
outside thread
standard speed: so designed that an effective oil recovery will be reached, at lowest
water rate
gear motor: 0,003 kW, 50 Hz, 220 V, simple construction with insulated cable
and clamping box
disc diameter: 200, 250, 300, 365 Ø
  • for easy, simple and undemanding applications
  • for small coolant emulsion tanks
  • for machining machines
  • small degreasing bathes
  • to cater for longer lifetime of the coolant emulsion
  • preferabel unit let run if oil is available, ease and floating on top

otfs 2OTF-2 S

For not or only less unsteadiness and high levels. At fall of levels up to lower edge of the disc the delivery of oil will be go back up to zero.

  • robust industrial construction
  • free lying shaft (partial with counter bearing)
  • maintenance free
  • extrem steep and large volumed drains
  • clain wiping
  • no oil impounding in the drains at usual viscosity
  • small constructind design with large capacity
  • special design possible
Application
For continuous and discontinuous separating oil and liquid grease floating on surface in spots or connected layers, as a thick layer or film or small spots from cold or hot condensate neutral up to basic or acid in calm and strong moving water.

For ground-water rehabilitation (bymeans of deep well), basin of treating, coolant amulsion, industrial effluents, Oil collecting basins, habour basin, refineries, railway depots, industrials washing-separators, shipping, degreasing bathes in galvanic firms (and industrial for metal processing), manufacturers for eatable oils, washing plants (for tankers, cars, lorries, busses, trams, trains, panzer/armor …).

Oils, liquid grease, petrol, kerosene, solvents and similar.

Performance range
oil recovery Q up to approx. 1.000 l/h
submersible depth ET up to 520 mm
speed n 0,5 – 20 min–1 (depending on Ø)
temperature t up to 100 °C
disc-Ø   250 – 1.400 mm
oil outlet nozzle R 1 – 3″ AG (or spezial nozzle)
rst water content < > <> 1 %

Function
Oil sticks to both sides of the down moving belt part, transported to top over the driving roll and nearly wiped off dry on down moving belt side, squashing away oil on the inside the belt is impossible with
our rolls.
Steep drains avoid, in usually viscocity, an oil block or splash over. Oil is quickly drained. Exactly horizontal mounting is not required. Floating solid parts and wind do not influence the function

Capacity
Dependet from oil layer thickness, viscosity, disc-Ø, submersible depth, water movement and speed. Rough appr. figure per each disc in standard speed: half disc width on top of water level in mm = l/h.

Construction
type: robust industrial design
wipers: adjustable by hand, very resistant, solid in consumption
total drain: total closed, oil outlet nozzle with outside thread
standard speed: so proportioned that there is the most effective oil recovery, with lowest water share
gear motor: 0,011 kW, in 3x 400 V, over that 230/400 V, 50 Hz, IP 54
disc-Ø: 365 up to 1400 Ø
disc number: up to 10
painting: undercoat, 2-fold of blue hammer finish paint, impact-resistant, bigger sizes with black special resistant paint

Special design
Total made of polypropylen PP, multiple discs, as a floating unit, according to ATEX, pressure air drive, hydraulic drive, oil outlet heightened and in one line with the disc (special at heavy fluently fluid).

Lesebeispiel in Kennlinie
Wieviel Öl in l/h bei folgenden Einsatzbedingungen:
Viskosität = 160 mm 2/s (cSt)
Ölschichtdicke = 10 mm
Drehzahl = 16 mm–1
Förderbreite Maß x = 500 mm

Ergebnis: ca. 500 l/h
* 16 min–1 nur bei OTF-2B ab Größe 400 und alle OTF-4B (die 16-min–1-Kennlinie entspricht in etwa der Förderleistung auch bei allen anderen OTF-Typen in der Standard-Drehzahl (nicht bei OTF-BE)).
