Integrative dust collectors for the highest demands
On 19 August this year, the 42nd Federal Immission Control Ordinance (42. BImSchV) came into force in Germany. This will impose significantly increased monitoring and documentation requirements on the operators of wet separators.
This said, can wet filtration still be considered a cost-efficient option?
Our innovative concept of dry dust collector with integrated explosion protection elements is pointing the way to a clean, future-proof alternative.
Collectors with integrated flameless explosion venting and isolation elements for metal dusts ST2 and ST3
Manufacturers of industrial dust collectors to be used in potentially explosive atmospheres inside buildings are facing complex challenges. Numerous details must be clarified and requirements complied with, from correctly determining the required vent area to designing the clean-air discharge to selecting the appropriate explosion isolation equipment.
The venting and/or isolation equipment is usually installed on a ready-made collector, a method which is rather expensive and complicated. It must be ensured that each component matches the elements already present in the unit and complies with all relevant requirements. Mistakes at this stage may impair the safe function and cause high consequential costs.
Presently there is hardly any economically viable solution available for metal dusts such as aluminium ST2 or ST3.
Joint development of customized all-in-one collectors
As a promising project, we offer you the joint development of an all-in-one filtration system, where
from the outset, all functions are exactly defined to suit the specific application
all components are optimally configured for the relevant purpose and mutually compatible
the explosion venting element is an integral part of the collector design
Towards the end of the project, we support you in conducting functional tests with a notified certification body, if desired.
Combining competencies – for developing a carefully designed, consistent solution
We rely on combining our key competencies with the know-how of forward-looking filtration manufacturers, based on the conviction that our concept of integrative dust collector holds huge potential for all parties involved.
All relevant material properties and design parameters, specific operational conditions and applicable requirements for the protective system are already identified in the planning stage and taken into account in the design of the collector. This critical preparatory work is the responsibility of a team of experts from the companies involved, who pool their expertise to determine and coordinate all steps to be taken throughout the project.
Gain a competitive edge
The integrative dust collector with its perfectly matching components is an attractive plug-and-play solution for your clients, both manufacturers and operators of plants, as it combines cutting-edge technology with unequalled convenience and reliability of operation.
Nobody in their companies will have to worry about the technical and legal details of explosion safety.

New BREX® module and optimized housing strength increase flexibility
Based on our scubex®series, we developed the BREX® module, which has all functions of a flameless explosion venting device and meets the relevant statutory requirements. As a central component of the novel filtration system, it is the first flameless explosion protection element that can be individually designed to suit a dust collector and to be fitted directly into the housing. Several BREX® modules can be combined to create the optimum venting solution for any dust collector.
The BREX® module is much smaller than other flameless explosion venting equipment.
The strength of the collector can be improved at moderate cost through targeted reinforcement provisions and the built-in BREX® venting modules. The strength of the housing, in turn, has an effect on the size of the required vent area.
Another outstanding feature of the integrative dust collector is our newly developed passive explosion isolation device, which has the following benefits:
the function is independent of the dust load in the volume flow
no minimum installation distances
maintenance-free (no sensors or detectors)
acts as pre-separator
reduced explosion pressure adjusted to collector housing
Passive explosion isolation device according to EN 15089:2009
The assembly inside the housing, through which the airflow passes freely, to some degree acts as pre-separator by extracting already part of the dust. Therefore the filter elements are not clogged rapidly and cleaning cycles can be reduced.
Environment – reusability saves money and resources
The BREX® will not be clogged with combustion residues, not even after several explosion. If it's not visibly damaged after an event it can continue to be used.
The blow-out flap, which is mounted inside a cassette, can be reclosed or easily exchanged, depending on the impact of an explosion.
The explosion isolation module can be exchanged without dismantling the entire unit.
