NEWS from REMBE®

The Explosion Safety team led by Dr. Johannes Lottermann moved into a new office building at Zur Heide in autumn 2019. The premises on Gallbergweg that have been used until now no longer offer sufficient space due to the constantly growing number of employees.

In addition to the ultra-modern offices, the new two-storey office building also houses a large, friendly lounge, which is also used for events such as the REMBE® Safety Days. The short distances to the production areas at Zur Heide and to the test field at the REMBE® Research + Technology Center that have resulted from the move enable even faster coordination between sales, development and production.

We operate sustainably – REMBE® is certified according to EN ISO 14001:2015 environmental management systems and attaches great importance to the careful, considered handling of resources. There was therefore no question that the issue of environmental and climate protection would play a major role in the planning of the new building. The focus here was on energy-efficient construction through the use of renewable energies such as heating with an air heat pump and energy-efficient glazing with automatic adjustment of the light exposure level. 

The findings and experience from the internal REMBE® green initiative were also incorporated into the new production and packaging methods.

The event series “REMBE® Safety Days” will continue this year. After the event topics Explosion Safety for spray dryers and Explosion Safety in the woodworking industry in the past, this year’s focus is on the food and beverage industry, specially the daily challenges in the food-, sweet-, grain- and convenience product plants as well as soft drink factories and breweries.

The REMBE® Explosion Safety Days combine the latest topics and presentations, top rank speakers as well as extraordinary evening events. It is a two-day networking event to exchange experiences and protection approaches.

A broad range of perspectives are required to obtain a holistic picture regarding Explosion Safety in the food and beverage industry. This is why the speakers at REMBE® Safety Days 2019 include operators, OEMs, insurance companies and authorities.

One of the highlights at the event is the live explosion demonstration carried out by REMBE® Research + Technology Center GmbH.

The event will be held in English due to the international audience. In addition to theoretical explanations and practical experience reports, a key importance is also placed on providing sufficient time for the personal exchange of information.

In the podcast episode DSS027 of the Dust Safety Science, Dr.-Ing Johannes Lottermann, Director of Explosion Safety at REMBE® GmbH Safety + Control talks about the German VDI standards for explosion safety.

 

During the discussion, Johannes explains:

-How the VDI standard compares with the ATEX standards commonly used in Europe

-The different parts of the standard, which are broken down by equipment type

-The ways that German regulations on combustible dust safety differ from those in other parts of the world

-The differences between dust explosion and gas explosion

Accreditation of the REMBE® Research + Technology Center as an independent testing laboratory

The REMBE® live demonstrations have been an integral part of the POWTECH for many years. The same applies to the key player Roland Bunse - an established figure in the world of Explosion Safety since the 1990s, who has been at REMBE® just as long, and has been head of the REMBE® Research + Technology Center GmbH for 2 years. With the accreditation as a testing laboratory according to DIN EN ISO 17025 the team around Roland Bunse the independence and professionalism appreciated by many customers was once again confirmed. In addition to the REMBE® Research + Technology Center, REMBE® GmbH Safety + Control will of course also be represented at POWTECH, but no longer in Hall 4 as before, but rather in the "new" Hall 5. At the booth 5-410, REMBE® engineers will be presenting a new non-return valve and the Q-Ball E flameless venting device especially designed for elevator in addition to other selected products.

Q-Flap RX™ non-return valve

The new Q-Flap RX™ non-return valve is a joint development between REMBE® and the Swiss company RICO. The Q-Flap RX™ is available up to DN 1250.

The strict requirements of EN 16447 are mainly achieved through the very high strengths and flexible installation distances. This is made possible by the so-called swivel carriage principle.

Isolation is essential for an effective Explosion Safety. No matter how much operators invest into (flameless) venting, if an isolation is missing the explosion can spread within the system and continue to propagate from one facility part to another.

Flameless pressure relief for elevators: Q-Ball E

The Q-Ball E, which is primarily designed for elevators, uses the principle of the contour-parallel relief developed by REMBE®. Thanks to the innovative design, the weight of the Q-Ball is very low. While comparable products from other suppliers weigh between 100-200 kg, the Q-Ball is an absolute lightweight with just 25-50 kg. This particularly facilitates the handling during assembly, as well as the requirements for an installation on the systems in the truest sense of the word.

 

REMBE® Process Safety and REMBE® Kersting GmbH

At POWTECH 2019, the REMBE® Process Safety business unit will also be presenting various new products, including a non-invasive signalling system and a newly developed graphite rupture disc.

In addition to the REMBE® GmbH Safety + Control with the business units Explosion Safety and Process Safety, as well as REMBE® Research + Technology GmbH, REMBE® Kersting GmbH will also participate at the POWTECH. A new, fully automatic sampling system will be presented, that is able to depict the entire process chain from the sample extraction in one part of the plant all the way up to the laboratory. In addition to inline sampling, REMBE® Kersting offers its customers products for flow measurements, and the silo weighing of bulk materials worldwide.

 

You will find the REMBE® Alliance companies in Hall 5, at Booths 5-407, 5-408, 5-409 and 5-410.

A graphite rupture disc that is setting new standards in terms of durability - also with regard to the application temperature. A rupture signalling device that is unbeatable in terms of process leak-tightness, as well as a combination of REMBE® rupture discs and safety valves, which is becoming increasingly popular especially in the chemical industry: these are our ACHEMA highlights. "At this year's ACHEMA trade fair booth, visitors will get closer to our products and solutions than ever before", promises Orhan Karagöz (responsible for the Pressure Relief division) and Dr.-Ing. Stefan Rüsenberg (Teamleader Technical Sales).

Michael Hüske, Sales Manager Germany, is especially looking forward to introducing the NIMU to the visitors. It's not the first non-invasive signalling device for rupture discs, but the latest and therefore state-of-the-art technology.

Conventional signalling devices require cables to be mounted on the rupture disc, which must then be routed out through the rupture disc holder. This is not the case with the NIMU. Here, a signal indicator is attached to the rupture disc during the manufacturing process. The actual sensor is screwed into a blind tapping in the rupture disc holder, where it monitors the position of the signal indicator on the rupture disc. This means that the wiring only starts outside the rupture disc holder.

The system is leak-proof, and back in operation quicker

After an overpressure event, and the associated opening of the rupture disc, the outlet part of the rupture disc holder must be removed, the rupture disc replaced, and afterwards the system can be put back into operation. The days when the signalling cables also had to be routed again to the respective switching box are finally over. This allows colleagues from the electrical department to devote their attention to other tasks.

Additionally: The process is absolutely leak-tight. The blind tapping in the holder replaces the tapping which is usually required. The absence of cable glands (required for the holder tappings for conventional signalling cables) means that the cable glands used cannot become porous, thus preventing an escape of the process media.

When the KUB® rupture disc opens, the NIMU sensor will output information to the process control unit of the system.

 

 

GRX® - cool and hot

If the process temperature is between -180 °C and 1,500 °C, the process involves corrosive media, and the rupture disc must already respond at a relatively low pressure, then the REMBE® graphite rupture disc GRX® is ideally suited to relieve the pressure. Thanks to a specially developed coating, the GRX® does not require polymeric sealants, and is able to withstand the aforementioned demanding process conditions, while still guaranteeing absolute leak-tightness. This in turn reduces the emissions of the system.

If the encounter of hazardous atmospheres with ignition sources cannot be prevented, the explosion protection remains as the only reasonable protection measure for operators. Even if this presumably only the third-best alternative, numerous applications have proven the contrary, because the prevention of explosive atmospheres as well as ignition sources, is often associated with an enormous burden. This applies to the construction of the plant, as well as for the costs of the plant operation.

If explosion protection is possible for gas applications, as of now this can be performed through a flameless pressure relief. ATEX certified and made in Germany.

The original of the flameless venting devices, the Q-Rohr®, is now certified for gas explosions. Originally developed for organic dusts, it has also been approved for different types of metal dusts, dual-fuel and gas engines for some time. In the field of gas applications, a broad range of plants in the chemical industry, as well as various test rigs have already been equipped with the Q-Rohr®.

Roland Bunse, responsible for new applications and upgrading (further) development of the Q-Rohr® since the 1990s: "The Q-Rohr® can be used anywhere, where gas-air mixtures could enable an explosion. This is the case in many industries and factories, whereas test benches are only one example thereof. I am looking forward to the upcoming inquiries - of which there are several interesting challenges currently available with very different applications, which we can all protect with the Q-Rohr®."

The Q-Rohr® consists of a explosion vent with a burst indicator, as well as a stainless-steel mesh filter.  In case of an explosion the explosion vent of the Q-Rohr® will open, the inserted special mesh filter will efficiently cool down the flames of the explosion and reduce any escaping pressure to a safe minimum. System and environment are therefore ideally protected.
