ATEX explosive zone measures
•If the device has been ordered for use in a potentially explosive area, make sure that no higher
surface temperature arises then permitted by ATEX.
The ATEX marking on the Goudsmit identification plate only applies to the product produced by
Goudsmit Magnetic Systems B.V.
•The ATEX certified magnetic device requires additional purchase parts to be certified to the ATEX
Directive. This includes control units, connection box(es), switch(es), sensor(s) and pneumatic
parts, etc. Make sure that these are fitted by qualified personnel!
•If the device is placed in storage or has a longer standstill, make sure the device is emptied and
cleaned.
•The device must be grounded, if a gasket is used between the device and the larger installation.
Attach a metal strip between the housing of the device and the installation, to make sure the device
is grounded.
•All screw connections inside the device must be secured against loosening.
The ATEX purchase parts are provided with their own ATEX markings.
Make sure no particles > 10 mm are present in the product flow.
These can damage the magnet or extractor bars or cause impact sparks.
If necessary install a mechanical filter (sieve) before the separating equipment!

Safety
10
Safety
Regularly check that all warning pictograms are still present and legible, and clean if necessary.
Make sure that new pictograms are applied at their correct locations if they have been lost or
damaged.
General
The device is provided with safeguards where necessary. Make sure every person who comes in contact
with the device, wears adequate personal protection (overalls, safety glasses, hearing protectors, helmet,
steel-toed safety shoes etc.).
Areas of the device considered dangerous are marked with warning pictograms.
If the device remains easily accessible to persons, then extra safety precautions (e.g. fencing) must be
installed. When safeguards are not possible, make sure clear instructions are given to people using the
device.
Danger of dust explosion
If this device is made according to an EX dust category (1D/2D/3D, acc. to ATEX equipment directive
2014/34/EU) it can accordingly be used in a dust zone (20/21/22, acc. to ATEX workplace Directive
99/92/EC). The Ex category is then described on the identification plate.
Make sure that the device complies to the correct explosion category.
Danger – dust explosion!
(no sticker on device)
Also check if the identification plates of mounted parts show the correct Ex-category for the Ex
zone in which the device will be used.
Danger of magnetic field
The magnets generate a powerful magnetic field that strongly attracts ferromagnetic (Fe) materials.
Always take into account that these materials may suddenly be powerfully drawn towards the magnet.
This applies to steel workbenches and steel tools, as well as ferromagnetic materials carried on your
person, such as coins in your wallet or your keys. Use non-magnetic tools and workbenches fitted with a
wooden worktop and preferably a non-Fe frame (e.g. stainless steel) whenever possible.
Remember that ferromagnetic items, including personal items, will be attracted - even personal
items if you are closer than 0.3 metres to a magnet.
Danger - strong magnetic field!
!
!

Safety
11
People fitted with pacemakers should never enter the magnetic field
(within a radius of at least one metre).
Prohibited for people with pacemakers!
Credit cards, chip cards, computer disks/tapes, computer screens, watches
etc. may be damaged or destroyed if they enter the magnetic field
(within a radius of at least 0.5 metre).
Danger for magnetic cards!

Intended use / user indications
Products
•Suited for separating ferromagnetic* (Fe) particles out of free falling powder and granular product
streams, grain size up to 10 mm, such as plastics, flour, sugar, coffee beans, etc.
•Not suited for fatty powders or raw materials with particle size over 10 mm.
Fe particles
•Suited for use in product streams with Fe particles of 30 µm and larger, dependant on magnet type.
See product specs for exact values.
•Product stream has to be free from Fe or other parts that can cause damage to the magnet bar
tubes (like dents/bumps)
Temperatures
•Suited for surrounding temperatures of -20°C up to +40°C and
•Suited for product temperature range of -40°C up to +80°C or wider, dependant on magnet type.
See product specifications for exact values.
The magnet is to be protected against higher temperatures than prescribed, because the magnet might
lose magnetic force permanently when exposed to high temperatures
Free space
Make sure that there is approximately 0.5 meter of free space around the clean flow magnet to perform
and ease the inspection and maintenance operation, like mounting or dismounting the magnet bars.
Air pressure
The (relative) over pressure in the product channel has to be less than 0.2 bar.
The (relative) under pressure in the product channel has to be less than 0.5 bar.
Noise level
---
Vibrations
The magnet is to be protected against strong external vibrations, because the magnet might lose
magnetic force permanently and or the brittle ceramic magnet material might break.

Separator specifications
13
Cleaning
Minimum 2x per day cleaning (Fe disposal) of the device is advised for an optimal magnetic Fe
separation and to prevent Fe accumulation on the magnet bars and the problems that can be caused by
that. Clean magnets have the best Fe separation result. So, make sure to clean more often than
assumed to be necessary, to achieve a satisfactory result of the magnet device.
Clean more often when necessary and less often when proven possible!
For dirt cleaning, see chapter Maintenance.
Separator specifications
High temperatures
When high temperatures occur, there is the possibility to use other magnet material than the (standard)
applied Neoflux® or Ferroxdure magnetic material.
Abrasive products
If you have an abrasive product, we can apply a protective coating such as tungsten carbide to the
magnetic bars and/or inside housing.
Please contact us for more information.
Use in food product flows
As standard, the SECF is delivered with a 3µm ceramic blasted (NON-food) finish.
On request this can be adapted so the Cleanflow can be used in almost any food flow.
The Cleanflow separator has got the product channel (SS AISI316) almost 100% magnetically covered.
The product channel (or even complete housing + magnetic bars) can be delivered in gap-free
SS AISI304 or AISI316 or in combination with other food-improved materials, such as those prescribed
or delivered by the customer.
Surface treatments like polishing, electrolytic polishing and wet blasting can be ordered from the factory.
ATEX
The standard clean flow magnets SECF are ATEX II 1/2D executed, suited for use in dust explosive
atmospheres zone 20 inside, zoned 21 outside.
It is however your own responsibility to take the right precautions when using the SECF in dust explosive
atmospheres, like in-time cleaning to prevent for thick accumulating dust layers, and suitable grounding
measures.
Read this manual thoroughly for all ATEX measures.

Working principle
Drawing:Cleanflow SECF
•The SECF manual cleaning Cleanflow magnet is designed to separate Fe (ferromagnetic*) parts out
of a product stream falling through the Cleanflow magnet.
•In the product channel 1 or more magnet bar layers are placed. When more layers, the layers are
placed over another in a way that the material stream passes the bars like in a cascade. The product
stream will therefore always pass minimum 1 magnet bar very closely.
•The Fe particles in the product stream will be attracted by the magnets and will "cling" onto the
tubes, while the cleaned material streams further.
•The Fe parts will stay on the tubes until it will be removed manually. This can be done by taking out
the magnet unit (Fe out) and executing a cleaning / Fe disposal action.
Unfortunately, product that gets stuck in-between and under separated Fe parts will fall off with it while
cleaning the magnet bars of Fe parts, and thus cause some "material loss".
Before every cleaning / Fe disposal cycle, the product stream has to be interrupted.
For an extra description of the cleaning / Fe disposal process:

Construction
Photo: construction of Neoflux® extractor type SECF (other types: see next page)
•The standard SECF has flanges with bolt holes for easy mounting in your product channel.
Other couplings can also be ordered.
•The SECF has 1 or more layers of magnet bars. When more layers, the layers are placed over
another in a way that the product passes the bars like in a cascade.
The product will therefore always pass minimum 1 magnet bar very closely.
•The magnet bars consist of a magnet package with bushes, a magnet package in a surrounding SS
tube, or a magnet package in a surrounding SS tube in a SS extractor tube – the extractor type.
The tube versions are waterproof.
•If the magnet device is an extractor type, then the magnet bars and SS tubes are each welded to an
end plate, which means that the extractor tubes and magnet bars can be shoved in and out of one
another as complete units.
•The assembled magnet bar unit can be shoved into the product channel through the hatch opening.
•The hatch can be tightened and held dust-closed by the fasteners and the mounted door rubber
band.

Installation
Transport and placing procedures
•Bolt a lifting lug to each of the 4 corners of the top flange of the magnet housing for stable lifting and
further transport. Keep each corner at the same level for proper alignment before installation. Pay
attention to possible unequal weight distribution.
Drawing: SECF lifting and transport
•Use proper lifting devices that are suitable for the device’s weight.
The weight of the device is stated on the identification plate.
•Clear the area under the magnet during lifting and transport.
•Mount the flanges of the device tightly to the inlet and outlet flange of your product channel. Improper
alignment and loose assembly may cause leakage of raw product.
•Ensure that the product channels are strong enough to support the weight of the clean flow magnet
and raw product in it. Reinforce them when necessary.
•Install the Cleanflow magnet SECF in a well reachable height for the operators. A good height eases
the working and cleaning process.
•Work safely; make sure there is enough working space, use proper scaffolding, ladders and other
help materials, so the device can be installed without safety risks.
Mount lifting belts at 4 lifting lugs.
Mount lifting lugs at 4 corner flange holes

Installation
19
Magnet bar protection
•The Cleanflow SECF has fragile tubes or bushes around the magnet material for protection. These
tubes and bushes have a small wall thickness, which ensures an optimal grade of Fe separation.
Disadvantage is however, that large, heavy Fe and or other particles in the product flow can create
bumps in the tubes and bushes, and consequently damage the magnet material underneath.
Ensure that large, heavy parts are filtered out of your product flow before it passes the Cleanflow!
Advise: place a sieve (filter) in front of the clean flow!
Also see chapter Maintenance.
Damage to the magnet bars and/or damage caused by damaged bars is not covered by guarantee.
Gasket material / grounding
To prevent the build-up of static electricity, make sure there is metal bridge between the magnetic device
/ product channel and the installation. The completed installation must also be grounded.
Electrical connections & EX
If the device is placed in an Ex zone, everything you add or change to the device's electrical installation
must be executed and documented according to the regulations for the specific Ex zone.
