Wider surface coverage.
Handle level variations up to 600 mm.
The 1U collector hose can cover liquid surfaces of up to 1 m² and accommodate level variations of up to 600 mm. A skimmer with a 300 mm disc accommodates about 100 mm and collects oil over a more local area. The 1U can be installed inside, above or beside a tank, with optional ceramic scrapers for high particle loads.
The continuously moving hose creates gentle surface circulation and brings oil from a wider area toward the skimmer. A disc enters and leaves the liquid at one location, creating much less surface movement.
Handle liquid-level variations up to 600 mm
A disc skimmer with a 300 mm disc can compensate for liquid-level variations of only about 100 mm. Larger variations require a larger disc skimmer. The disc diameter therefore limits the level range over which a disc skimmer can continue to operate.
Geared-motor and component durability
The robust geared motor used on the 1U offers a significantly longer service life than the 12 V or 24 V motors commonly used on disc skimmers. Other wear parts are also made from high-quality materials and need replacement only rarely.
Optional ceramic wipers for high particle loads
Rubber wipers used on disc skimmers need relatively frequent replacement once the oil contains particles.
For particularly high particle loads, the 1U can be equipped with ceramic wipers to overcome this problem.
Flexible installation inside or outside the tank
A disc skimmer must always operate inside the tank, requiring space and a suitable opening. The 1U can be adapted to local conditions and, where necessary, installed on, inside or next to the tank.
Continuous oil pickup with an oil-attracting hose
The oil-attracting hose is the only regular wear part. Its service life is about three months under extreme conditions and typically around twelve months. Disc-skimmer discs are often made of plastic and may deform at higher bath temperatures. Because the wiper cannot compensate for a warped disc, only part of the adhering oil is removed.
Differences at a glance
- The FRIESS 1U can remove oil thoroughly from surfaces up to 1 m².
- The 1U easily compensates for liquid-level variations up to 600 mm.
- Its robust construction makes the 1U suitable for continuous operation.
- The stainless-steel wipers in the FRIESS 1U provide a long service life even under demanding operating conditions.
- The 1U can be installed inside or outside the tank.
- With few exceptions, the FRIESS 1U is made of stainless steel, avoiding the deformation problems associated with plastic components.
