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 groundwater remediation (via deep wells), clarification ponds, coolant emulsions, industrial wastewater, oil sumps, port facilities, refineries, railroad depots, industrial washing plants (for machine parts), pickling plants, oil separators, 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 the like.
Features
- Robust industrial design
- Free-flying 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 special version
Field of application
Functionality
A tension roller keeps the belt vertical. It cannot fall out even in the event of water turbulence, wind or if solid particles get between the belt and the tension rollers.
Oil is attracted to both sides of the downward-moving belt section, conveyed upwards over the drive roller and wiped off almost dry on the downward-moving belt section. With our rollers, it is impossible for the oil to be squeezed away on the inside. Steep drainage channels prevent the oil from backing up or spilling over at normal viscosity. Oil is drained away quickly. Horizontal installation.
Funding data
Dependent on oil layer thickness, viscosity, belt width, water movement and speed. Rough guide value at standard speed: Belt width in mm = l/h (non-binding).

Construction
OTF-3 B (made entirely of polypropylene) / OTF-5 B (with gravity drain)
Special version
Drain hose ready for connection, pump, adjustable, explosion protection according to ATEX, firedamp protection, hydraulic motor, compressed air motor, level switch for oil collection tank, double-walled heatable drain channels by means of steam or hot water feed, draw roller safety device, draw roller holder (for agitator tanks and strong water movement), with gravity drain for very difficult or non-flowing draining media, protective grille against coarse soiling, oil outlet on the left as seen from the motor. For even better oil drainage, if viscous or contaminated, the oil drain is available for every appliance up to two nominal sizes larger (not for OTF-1B 60).
Dimensioned drawing
Characteristic curve
Reading example in characteristic curve
How much oil in l/h under the following operating conditions:
Viscosity = 160 mm²/s (cSt = mPas)
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)).

OTF-3B belt skimmer
An oil skimmer developed for applications in the chemical industry where the usual materials steel, aluminum, stainless steel are not sufficient. Made entirely of polypropylene with polyethylene band. With seal to the engine compartment.
The shaft is completely sealed and protected. With large-volume and steeply arranged drainage channels. Available sizes, with immersion depths ranging from very short to extremely long.
