Description:

We develop, construct, manufacture and deliver upstream agitators. These types of mixers generate a special upstream which supports the mixing process and stabilize the agitator at the same time.
The US mixer is a low-speed mixer; therefore it works energy-efficient.

Application:

The US mixer cannot be used for sludge or higher dry substance contents. We use our mixer for dry substance contents up to appr. 4% and for speeds up to appr. 30 min-1.

It is used in aeration and denitrification tanks, primary anaerobic tanks. For sludge liquor tanks and mixing- and equalizing tanks.

It can be used for max. diameters and edge lengths of 2,0 up to 20,0 m and a max. water depth of 2,0 up to 8,0 m

Tank capacities up to 2000 m³ can be stirred with only one of these type of agitators.

Special Benefits:

• No or very little sediments on the tank bottom
• No air input and aerosol discharge through the surface
• Clam water surface    
• Vortex-free recirculation
• On extra using pedestal necessary
• Individual design and optimised for different customer requirements
• Slowly turning mechanical agitator with drive in dry arrangement and vertical shaft
• Welded propeller with 2 blades for all diameters
• Radius formation adapted to circumferential speed
• Direct thorough mixing and homogenisation
• Propeller designed for gentle treatment of floccs
• Stable spur gear motor with housing in agitator design
• Installation and removal possible at filled tank
• Stabilisation through bore-holes in the blade
• No need for gear dismantling / installation to change oil
• Left-hand or right-hand rotation available, provided that the agitator is designed accordingly
• Quick homogenisation with slow rotational speeds caused by turbulences on the back side of the blades

The following materials are available:

• Steel-galvanized or coated
• Typical stainless steels (s.s) like s.s. 304 or s.s. 316 / s.s. 316 Ti
• For special requirements we can even offer special materials like 1.4462, 1.4539 (Duplex) or even higher alloys like Hastelloy

The following options are available:

• R-US-SB  = special floating sludge destroyer
