PERMITTED USES
The mixer is suitable for installation on Biogas digesters; it can be mounted on the wall or the ceiling
of the tank, and is designed to homogenise the biomass, even in the presence of non-homogeneous
material.
The BG80 mixer must be used exclusively for the homogenisation of biomass in digesters and in fermentation
containers with fermentation substrates, such as sewage, non-homogeneous material and other co-ferments.
This mixer cannot be used to homogenise and mix the following substances:
Mud residue from clarification
Solid, voluminous substances
Materials with sharp edges that may damage the mixer
Materials mixed with foreign bodies (cords, ropes, plastic ribbons,...)
All uses other than that specified herein are prohibited.
The user and owner of the mixer shall therefore be held directly responsible for any damage resulting from
incorrect use of the product.
To ensure correct use:
- Adhere to the instructions contained in this booklet;
- Observe the specified intervals for checks and maintenance operations.
In order to comply with the product classification in accordance with ATEX directive 94/9/EC, users must
respect the technical data specified on the information plate and the documentation; the latter must be stored
near the equipment, or somewhere known and easily accessible to the user and the maintenance technician.
Transport, storage, maintenance, and commissioning operations, etc., must be performed by specialised staff
in areas free from explosive atmospheres. It is mandatory that the electric power supply to the mixer is
deactivated during such operations so that the mixer out of service, and the operator must take all possible
precautions against any conditions which may cause the involuntary start-up of the mixer, or any movement of
the unit parts.
The BG80 mixer is intended for use in atmospheres at risk of explosions due to the presence of gas-air
mixtures.
Equipment pertaining to group II and category 2 can be used in zones 1 and 2 where explosive atmospheres,
in the form of gas clouds in the air, may occasionally occur during operation; only use the mixing unit with other
equipment if the latter equipment is authorized to operate in the same zones.
The instructions provided in this manual are only applicable to biogas digesters that are used in
areas with potentially explosive atmospheres.
Failure to observe the safety instructions may cause explosions!
The ATEX mixer, identified by the Ex mark, is certified - in accordance with the explosion-proof protection
method specified on the plate - for operation in the presence of Explosive Gas in environments classified as
zones 1 or 2
