OTF-1S disk skimmer
Oil skimmer specially developed for coolant emulsions, but can also be used for other applications.
- Disc Ø 200, 250, 300 and 365 mm
- Motor: 230 V, 50 Hz, 3 Watt, synchronous geared motor in accordance with VDE 0530/0730, to be connected in accordance with protection class I, earthed with additional terminal box
- Separation between washer (water part) and appliance by means of plastic connection
- With protective roof
- For fixed mounting
- Made entirely of stainless steel, adjustable Teflon wiper
- For simple, undemanding areas of application
- For small coolant – emulsion containers
- For processing machines
- Small degreasing baths
- Ensures longer service life of the coolant emulsion
- Preferably run the appliance when oil is present, has calmed down and is floating on top
Special version: threaded connection R 1″ AG, clamping device, drain hose ready for connection, level switch for oil collection tank
Construction
OTF-2S disk skimmer
With little or no fluctuation and high levels. If the level drops to the lower edge of the disk, the delivery drops to zero.
- Robust industrial design
- Exposed shaft (partly with counter bearing)
- Maintenance-free
- Extremely steep, large-volume drainage channels
- Clean stripping
- No oil build-up in drainage channels with normal viscosity
- Small compact design with high performance
- also according to ATEX
- also special version
Use
For continuous or discontinuous separation of oil and liquid fat, floating on the surface, in patches or continuous layers as a thick layer or wafer-thin films or patches, from cold or hot condensate, neutral to basic or acidic in still and strongly agitated water.
For coolant emulsions, industrial waste water, oil sumps, refineries, railroad depots, industrial washing plants (for machine parts), pickling plants, shipping, degreasing baths in electroplating plants (and metalworking industry), production of food oils and fats, washing plants (for tank vehicles and cars), food industry. Oils, liquid grease, gasoline, kerosene, solvents and similar.
Field of application
Functionality
Oil is attracted to both sides of the downward-rotating disk section, conveyed upwards and wiped off almost dry on the downward-moving disk section. Steep drainage channels prevent a build-up or spillage at normal viscosity. Oil is drained off quickly. Exact horizontal installation is not required. Floating solids and wind do not affect the function.
Funding data
Dependent on oil layer thickness, viscosity, disk diameter, immersion depth, water movement and speed. Rough guide value per washer at standard speed: half washer width at top edge of level in mm = l/h.
Special version
Made entirely of PP, several disks, as a floating device, with explosion protection in accordance with ATEX, compressed air or hydraulic motor, oil outlet enlarged and in line with the disk (for poorly flowing media).
Reading example in characteristic curve
How much oil in l/h under the following operating conditions:
Viscosity = 160 mm2/s (cSt)
Oil layer thickness = 10 mm
Speed = 16 mm-1
Conveying width dimension x = 500 mm
Result: approx. 500 l/h
* 16 min-1 only for OTF-2B from size 400 and all OTF-4B (the 16 min-1 characteristic curve also corresponds approximately to the delivery rate for all other OTF types at the standard speed (not for OTF-BE)).
