STEINIG-Oil Skimmer OTF-S (with disc)Following descriped Type: OTF-1 S, OTF-2 S, OTF-3 S
|
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
OTF-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
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 rangeoil 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.
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).
Performance curve
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)).
OTF-3 S
- for simple applications, spezial at metal-cutting machines
- disc-Ø 205, 300 and 400 mm
- disc 205 and 300 Ø mm made of stainless steel, 400 Ø mm made of plastic
- oil recovery rate without obligation at best covered oil layer up to 5 l/h
- temperature at disc of stainless steel up to 90 °C and of plastic up to 80 °C
- motor: connection 230 V (one phase only), 50 Hz, operating voltage 12 V, with loose time switch, with shock-proof plug and cable, integrated transformer and adjustable speed over setting voltage
- mounting over strong foot magnet
- wipers of polyurethane PU
- with 2 setting possibilities over lever screws, thereby the built-in position can
be installed in the best way - for simple and undismanding applications
- for small coolant emulsion tanks
- for Bearbeitungsmaschinen
- for small degreasing bathes
- to cater for longer lifetime for the coolant emulsion
- preferable unit run if oil is available, oil is settled down and floating on top
