Application fields

Fermenter, secondary fermenter

Your benefit concerning biogas plants

The biogas agitator Bo-Bu-Mix is a robust mixer with low to medium speed ratings and offers very high peak performances especially for dry matter whose contents vary between medium and high. A high degree of safety is ensured by sealing with strong expansion joints and the use of ATEX-motors.

Installation and maintenance

Installation and maintenance can be performed easily from the outside.

Design and quality

High-class components plus a robust design lead to a long product life.

Submersible and angularly adjustable agitator for lateral installation

The built-in agitator Fermix is submersible to a depth of up to 25 meters, as a special construction up to 100 meters. Thus it can be installed in any container. Attachment parts for concrete and steel tanks are available. The agitator can be adjusted at an angle of 20°, to the right and the left and as well up and down.
This agitator is as well very suitable in combination with large wing mixers. Installation and dismantling can be carried out from the outside without having a person climb into the tank. Fermix is available with a geared motor from 7.5 kW up to 22 kW or with a hydraulic motor. The rotary frequency of the wings is about 300 to 400 RPM, depending on the model.
The wetted parts are zinc-coated or made of stainless steel (V2A or V4A).

• Agitator shaft: standard length 3700 mm
• Sealing: face seal SiC/SiC
• Bearing: tapered roller bearing and rolling contact bearing in oil bath
• Blade: 3-blade, pushing
• Geared motor

• Concrete formwork for wall-mounted frames, zinc-coated or stainless steel
• Wall-mounted frame, fixed – non-adjustable
• Wall-mounted frame, angle-adjustable with expansion joints up to 20°
• Geared motor, ATEX-certified
• Geared motor, special voltage
• Agitator length up to 5200 mm

Fermix is an agitator for flexible and versatile use. By adjusting the angle it can be adapted to changing requirements. As this agitator allows to be stacked it can be installed near the bottom of the tank in order to avoid sinking layers.

Due to the use of strong expansion joints the agitator is leakproof.

In an easy way from the outside.

Most of the services can be carried out from the outside.

Combined drive with tractor possible

This biogas agitator was developed for use in fermenters, secondary fermenters and combination storage tanks.

Due to v-belt drive the noise development could be reduced. The multi-part driveshaft allows that most of the maintenance work can be carried out from the outside.

• Connection plates resp. sealing systems are available for all types of tanks.
• Combined drive with a tractor is possible in difficult cases due to installation in the bottom section.

• Motor rating: 15 kW, 18,5 kW and 22 kW
• Motor speed: 1.000 RPM
• Propeller speed: 312 - 335 RPM
• Three-blade propeller: ø 560 and 600 mm
• Sealing / bearing: face seal, tapered roller bearings, ball bearings
• Material: optional zinc-coated, V2A or V4A (stainless steel)

As shown, with base supports and, depending on type of silo, with various wall sealings

Stainless steel propeller – planetary gear – compact design

The submersible agitators „Turbomix“ are particularly suitable for the homogenization of liquid manure, sewage sludge and biogas substrates.

Due to compact design and streamlined shape and because of the usage of planetary gearing and 4-pole motors, the engines are notably energy-efficient. (Types 1.5/6 and 2.2/6 have direct drive motors.)

The usage of stainless steel propellers with a high blade strength and face seals guarantees a long product life.

Thermal sensors built into the motor’s winding protect from overheating.
Insulation class "F" · protection class "IP68" · immersion depth max. 20 meters

• Complete homogenization of liquid manure after storage season
• Rapid agitation of sinking and floating layers concerning pig, cattle and poultry slurry
• Homogeneous manure is the basis for exact manure dispersion and an optimum fertilization effect. The device runs quietly and can be used unattended. As the agitator is operating immersed in liquid, it causes less emission while stirring.
• By using the installation variants as shown below, the Turbomix can be adjusted to the filling level in silos, receiving pits or fermenters. As well the flow direction of the propeller can be set for optimum performance.
• Used in a biogas plant, the agitators stand out due to best possible adjustment possibilities and a low power requirement.
• Optimum use of the digester is feasible because dead zones and sediments are avoided.

Due to reduced flow turbulences and the use of planetary gearing, the Turbomix agitators are highly energy-efficient. Depending on the electricity rate, a fairly low consumption can be achieved.

"Turbomix" with 8 m electric cable, installation kit for head tank with work platform; biogas fermenting containers or receiving cesspits available. Accessories are compiled according to the installation conditions and to your requirements. A transport trolley for mobile operations is also available.

Simple and quick installation, also in case of tanks which are already filled.

Maintenance is limited to visual check and oil change depending on operating hours.
