Different versions, approved for organic and metallic dusts
Our devices are certified according to Directive 94/9/EC or 2014/34/EU to be used with a variety of organic and metallic dusts. The EC Type Examination tests according to EN 16009:2011 were carried out with organic and 99.5% aluminium material of the dust explosion class ST2.
The housing easily resists pressures up to 2 bar.
Due to its modular design, compact dimensions and various size options, the system can be adjusted to suit individual requirements, no matter if a facility needs upgrading or is in the planning stage.
Low surface and exit gas temperatures increase safety
Unprecedented temperatures of below 50°C on the surface of the device and below 100°C of the exit gas were measured immediately after the explosion-exceeding by far the safety requirements defined by the relevant standard, which, in this respect, is insufficient.
The strong cooling effect is produced by our in-house developed Energy Absorber in combination with the flow-optimized design of the insulating housing.
The above-mentioned temperatures were measured and documented during the EC Type Examination tests with non-metallic ST2 dust.
Continued protection in case of subsequent explosions
All tests with various dusts have shown that flame emission is prevented even in the event of a subsequent explosion, an additional safety feature not yet provided for in the relevant standard.
Unlike the rigid mesh filters used in other flameless venting systems, the elastic metal structures inside the scubex® are not significantly clogged with dust and combustion residues. Therefore the protective function is maintained after an explosion. During the EC Type Examination procedures, up to four successive explosion tests were carried out successfully with one device, without dismounting or cleaning the sample between the tests.
This added value is provided at no extra charge.
Reusable, exchangeable blow-out flap
Due to its unique properties, the scubex® can be reused up to three times, depending on the dust material and severity of the explosion.
Only the blow-out flap must be replaced after an event—there is no need to dismantle the entire device. The flap is mounted inside a cassette, which is easily accessible and can be pulled out after removing a few bolts:
If the frame is not seriously damaged after an activation caused by a minor pressure increase, the blow-out flap can be simply reclosed.
scubex® cool+clean – exchangeable filters for defined cleanliness
If you have special requirements for cleanliness or want to minimize downtime, the scubex® cool+clean with additional heat-resistant particulate filters Class M6 is the ideal option (fine dust filters Class F8 are available on request; classification acc. to EN 779:2012). These filters retain the dust particles (size ≥ 1µm) released during an explosion almost completely and improve the protective and cooling efficacy.
The required safety distance is further reduced.
The filter elements, too, are easily replaceable.
scubex® easy+clean – the economical compact version
The scubex® easy+clean version, developed for plants that mostly work with organic dusts, is characterized by an even more compact design, reduced weight and outstanding value for money.
Benefits of all scubex® versions:
We are proud of having developed a system for flameless explosion venting that actually re-defines the state of the art: the scubex® series exceeds the safety requirements laid down in the EN 16009 standard in more than one respect.
