H₂-ready Buy · Hire · Have us flare for you
Rugged stainless-steel flaring units for natural gas, biogas, propane, town gas and hydrogen — the DN 50 up to 16 bar. DBI-tested with over 99 % burnout under Article 17 of the EU Methane Regulation. Buy, hire or let us do the flaring.
EU Methane Regulation 2024/1787
Article 17 of the regulation sets two requirements for gas flares. For all units — including existing ones — the deadline expired on 5 February 2026. The DN 25 and DN 50 gas flares meet both, verified by DBI Freiberg.
The regulation permits no more than 1 % residual methane in the exhaust. DBI — Gastechnologisches Institut gGmbH Freiberg, an independent group of companies within DVGW — tested both sizes to EU Methane Regulation 2024/1787, VDI 2105 (10/22) and TA-Luft (08/2021). Both units carry the DBI test mark.
Both gas flares use a standing propane pilot flame that burns throughout the entire flaring operation. That is precisely why the regulation requires it: escaping gas is re-ignited at any time, even if the main flame briefly goes out. A 6 kg propane cylinder typically lasts 48 to 72 hours of continuous operation.
Flared volumes must be recorded and documented in a verifiable manner. The volume measuring case logs flow rate and quantity as a PDF alongside the flaring operation — for authorities, QM and audits.
| Feature | Highest measured residual methane | Burnout |
|---|---|---|
| Gasfackel DN 25 | 0,16 % | at least 99.8 % |
| Gasfackel DN 50 | 0,57 % | at least 99.4 % |
On the DN 25, no residual methane was detectable from 0.5 bar flow pressure upwards. On the DN 50, the highest value was measured at flow rates up to 1,800 m³/h.
And in hydrogen operation? In January 2025 DBI additionally tested the DN 25 with pure hydrogen (99.9 %). At 100 to 360 m³/h and 0.10 to 0.40 bar flow pressure, unburnt residual hydrogen ranged between 13 and 0.5 ppm — DBI certifies complete burnout up to 0.4 bar and 360 m³/h. According to the report, hydrogen operation produces significantly higher NOx values than natural gas; for short-term flaring these are not subject to limit values.
The two requirements above concern the unit. Two more are addressed to you as the operator. We reproduce them here to the best of our knowledge — assessing them for your plant is up to you.
“Where auto-igniters or continuous pilot burners are used, operators shall use flame monitors for continuous monitoring of the main flame or the pilot flame to ensure that no gas is released unburnt.”Article 17(4)
Our units work with a continuous pilot burner. The optical flame monitoring performs exactly this task — it is included in the PREMIUM PRO PLUS (DN 25) and PREMIUM-PRO+ (DN 50) versions. We recommend it; whether it is required for your application is your decision.
“Where the gas flares or other combustion devices are not used regularly, operators shall inspect them before each use.”Article 17(3)
Regularly used flares must be inspected every 15 days. Mobile units are usually deployed irregularly — then the check applies before every use. Any irregularities found must be rectified within six hours. We brief your team on this.
These statements reproduce the text of the regulation and do not constitute legal advice. How Article 17 applies to your plant is for you or your consulting engineer to assess.

A bluff body sits across the pipe. Behind it, vortices detach alternately to the left and right — a regular double row, named after the physicist Theodore von Kármán. Over a wide range, how often a vortex detaches depends solely on the flow velocity: twice the speed, twice the frequency.
Flow
Bluff body
6,0 m/s·× 20 vortices per second compared with 0.3 m/s
Watch this while dragging: the vortices do not move closer together. Their spacing is set by the width of the bluff body, not by the velocity — they simply pass by faster. That is precisely why more of them reach the sensor per second.
Hold a stick in a stream. Behind it, eddies form — one to the left, the next to the right, always alternating. If the water runs faster, the eddies follow each other faster. That is exactly what happens in the measuring case, only with gas: a bluff body sits in the pipe, and behind it the unit counts the vortices. The number of vortices per second gives the velocity; velocity times pipe cross-section gives the quantity. The same phenomenon makes a flag flutter in the wind and an overhead line sing in a storm.
The slider spans the unit's measuring range: 0.3 to 30 m/s in the measuring section. The figures are to scale. The motion in the picture is compressed — across the whole range the frequency changes a hundredfold, which at the upper end could no longer be followed.
The measuring case counts these detachments. Because only their frequency matters and not the force of the flow, the density of the gas is irrelevant. For flaring that is the decisive point: natural gas, biogas, propane and hydrogen differ in density by a multiple — a density-dependent method would have to be recalibrated for every type of gas.
You specify the gas — the device does not. For the conversion to standard cubic metres you enter into the device which gas you are flaring. It cannot verify this: it counts vortices, not composition. Whatever is entered, it takes as given. The wrong gas means the wrong standard value — and that value then appears in the report for the authorities.

You are not just buying a device. We configure it for your application. We service it, repair it and handle the annual inspection of the fittings — in our workshop in Leipzig. On the phone you reach someone who does the flaring himself. And when it is urgent, a hire unit is ready for collection within an hour. Anyone looking only at the purchase price will find cheaper. Anyone who wants the device to work when they are standing in front of it is in the right place.
Key features
DN 50 up to 16 bar, DN 25 up to 5 bar. Flow pressure is the pressure actually present at the unit while flaring — the higher it is, the greater the possible gas throughput.
Flow pressure = the pressure in the moving gas right at the unit (not the static pressure). It determines how much gas can be safely flared per hour.
Shown: the upper riser with flame monitoring and the fitted diffuser extension tube (DN 50, +1,800 mm, stainless V2A). At high flow pressure the extension pushes the flame outlet further up — heat radiation moves upward and radiant heat at ground level drops noticeably. Guyed with three eyelets, use from 1 bar line pressure.
The venturi nozzle — VENKRO 25 for the DN 25, VENKRO 50 for the DN 50, both patent pending — actively draws the residual gas out of the line, down to the ppm range and thus far below 50 % LEL. A separate nitrogen purge can be dispensed with: no cylinders to order, transport, connect and return.
Venturi nozzle = a constriction where flowing compressed air creates a vacuum and draws residual gas out of the line — without any pump.
Shown: the Venturi nozzle with compressed-air connection. How to draw down the line — oil-free compressed air creates a vacuum in the nozzle and pulls residual gas out of the line. Use only oil-free site compressors at 8–16 bar and at least 1.6 m³/min. Open a vent at the far end of the line. When the primary flame goes out: close the air, measure the gas concentration — only shut down below 50% LEL.
Optional for both units — optical monitoring reliably checks the flame, even with hard-to-see gases such as hydrogen.
Optical flame monitoring = a sensor detects via light/UV whether the flame is burning and reports any flame-out immediately.
Shown: the display of the optical flame monitor. Press the central main switch — red LED = battery OK, no flame detected (including methane and hydrogen), green LED = flame burning. The LiFePO4 battery lasts about 120 hours of continuous operation; recharge after 20 days of non-use at the latest.
Quick setup — the unit is ready to operate in about two minutes. The necessary tools are included in the case, ideal for changing sites.

Rule of thumb: For residual-gas volumes up to roughly 700 m³/h (at 5 bar) the DN 25 is sufficient. If you regularly flare larger flows or work at high pressure, the DN 50 is the safe choice — and it also covers the DN 25 range for mixed use.
When does a gas flare need a flashback arrestor? It depends on whether the flare tube is open at the top. On the DN 50 it always is: no back pressure can build up that would let a flame travel back into the line. A flashback arrestor is therefore not required by design – the unit carries the IBEDA GRV50 gas non-return valve, and in the 5 bar version the GRS50 safety fitting to DIN EN ISO 5175-2. Before every job you have to check that the flare tube is clear anyway. There is no silencer for the DN 50. The DN 25 comes with a screw-in silencer in its case. Once it is fitted, the system is no longer open at the top – and then a flashback arrestor is mandatory. Without the silencer the same applies as for the DN 50.
Transport and carrying The trolley rolls. If it has to be carried, the manufacturer specifies the end handles and two people — otherwise the permissible load is exceeded. If only one person is available, the trolley and the riser unit can be carried separately. On the DN 25 that is 15 kg for the unit and 15 kg for the trolley, on the DN 50 38 kg and 27 kg.

System components in detail
Performance classes
The decisive question is not which flare is bigger. It is: what line pressure can you connect to directly — without reducing first?
| Performance class | Maximum pressure | Direct connection up towithout pressure reduction |
|---|---|---|
| Small flare for service connections | around 1 bar | around 1 bar |
| Mobile low-pressure flare | around 1 bar | around 1 bar |
| Mobile medium-pressure flare | around 2 bar | around 2 bar |
| Gasfackel DN 25 | 5 bar | 5 bar |
| Gasfackel DN 50 | 16 bar | 16 bar |
| Gasfackel DN 50with pressure reduction station | 100 barg | 16 bar |
About these figures: The figures for the market classes summarise publicly available manufacturer data and deliberately name no individual competitors. Throughput values from different manufacturers refer partly to normal cubic metres, partly to operating cubic metres — a direct numerical comparison is therefore only possible to a limited extent. What is unambiguously comparable is the permissible pressure.
You are standing at a line with 4 bar. With a flare rated for 1 or 2 bar you also need pressure reduction: another unit that has to be transported, set up, connected and included in the risk assessment. With the DN 50 you connect directly.
The surcharge for the 16 bar version over the 5 bar version is €175 — on a unit price from €11,119 net that is 1.6 %. Anyone who works on a line above 5 bar even once a year has recovered it.
For transmission lines and pipelines at 40 to 100 barg there is the mobile pressure reduction station: it brings the pressure down to 10 to 25 barg, with ATEX-certified fittings, for methane and hydrogen. The same DN 50 then covers the high-pressure range too, instead of requiring a second flare system.
Not sure what pressure actually reaches the unit in your case? That is exactly what the consultation is for — static pressure and flow pressure are two different things.
Accessories
A flare alone is often not enough for a compliant operation. The volume metering case is listed above as a system component — here is the supplementary accessory range, matched to DN 25 and DN 50.
Raises the flame outlet by 1,800 mm for greater safety distance and visibility. Stainless V2A, with three eyelets for guy ropes. Use only from 1 bar line pressure — at lower pressure the flame burns incompletely inside the tube.

includedBuy, hire or have us flare
You do not necessarily have to buy a unit. Which route suits you depends on how often you flare and whether you have your own trained staff.
Hire
For a single construction project, an incident or a trial run before procurement you do not need to buy a unit. Both sizes are available for hire — fully equipped.
| Feature | Hire | Purchase |
|---|---|---|
| Suits | single project, incident, trial run before procurement | regular network operation, several crews |
| Minimum period | 1 day · dispatch to return | — |
| Billing | daily, weekly or monthly rate | one-off |
| Deposit | normally none | — |
| Credit | creditable against a later purchase by arrangement | — |
Our hire units are consistently fully equipped — you are not renting the stripped-down version.
Delivery by forwarder, delivery by us or collection in Leipzig — your choice. A briefing at the unit is available on site for a surcharge, or online via Teams or Meet. By phone works too, but it is the more awkward route: when flaring, it helps if we are both looking at the same unit.
Incident? If a hire unit is in stock, you can collect it in Leipzig within one hour. Call instead of ordering — on the phone it takes two minutes to establish what is available.
Tell us the period, the application and the line pressure. We will quote daily, weekly and monthly rates on request.
Flaring service
You do not have to buy a unit, nor hire one. If you need to get rid of residual gas once or twice a year, we come to you with the flare and carry out the operation.
The scope follows your needs: setting up and running the flare only, or additionally recording the quantity with the volume measuring case including the log for your documentation. On site you will find the owner himself or a colleague. We operate throughout Germany; at short notice too if unit and staff are available. Billing by arrangement — scope and effort depend on the job.
We work with an open flame and corresponding thermal radiation. For the job to work, we need the following from you:
We bring the propane cylinder for the pilot flame ourselves.
Only you can judge which approvals and permits your site requires — that depends on your plant, your operator and the local authority. We tell you what we need technically; the operational clearance rests with you.
Applications
Before any work on a line, the residual gas must go. The flare burns it in a controlled way outside the work area.
During filling, gas displaces the air. The gas-air mixture passes through the flare and is burned off cleanly.
Flow rate and volume must be captured and archived — handled by the volume metering case in parallel.
Procedure
Using the DN 50 gas flare as the example — from setting up to the packed case. The DN 25 works the same way, just one size smaller.
This overview does not replace the operating manual. What is binding is the unit's operating manual and the rules for working on gas-carrying systems, such as DGUV Information 203-090. The manual comes with every unit; we will send it to you in advance on request. Would you rather hand the job over? We can flare for you.
Knowledge & practice
Questions that come up on the phone again and again — answered in more depth than a FAQ allows.
Siloxane vapours burn to silicon dioxide on the hot catalyst and settle as a glassy layer on the active surface. The sensor does not die, it goes deaf. That is exactly what makes it dangerous: a failure is noticed, a reading that is too low is not.
| Sensor type | What happens |
|---|---|
| Pellistor — catalytic bead, Ex and CH₄ measurement | The most critical case. SiO₂ coats the active surface, the reading drops too low or to zero. Irreversible — the sensor has to be replaced. |
| Zirconia O₂ — residual oxygen, 600–700 °C | Same mechanism, because it also works hot. SiO₂ clogs the porous electrode: drift and sluggish response. |
| Electrochemical cell — O₂, CO, H₂S | Less prone to actual poisoning. But an aerosol film on the sintered filter and diffusion membrane lengthens the response time and damps the reading. |
| NDIR / infrared | Immune to poisoning. But a silicone film on window and mirror reduces transmission — usually still recoverable by cleaning. |
Spray mist from several metres away, or vapours from freshly treated parts in the same room, is enough.
In practice: silicone spray does not belong in the same tool case or the same cab as the instrument. The same goes for silicone-based sealing greases, mould release agents, leak detection sprays and some hand care products. For seals and PE push-fit connections use silicone-free lubricants — soap- or PTFE-based. That is the better choice anyway, because silicone residues later cause wetting defects in coating and problems in welding.
The gas quantity under standard conditions follows from the geometric volume of the section and the absolute pressure:
Standard volume ≈ length × cross-section × absolute pressure
The absolute pressure is the operating pressure plus roughly 1 bar of atmospheric pressure. The cross-section is π/4 × diameter squared.
| Section | geometric | standard conditions |
|---|---|---|
| Distribution main DN 200, 500 m, 4 bar | 15,7 m³ | ~79 m³ |
| Transmission line DN 500, 5 km, 16 bar | 982 m³ | ~16.700 m³ |
For the duration this is a rough orientation at best. At 5 bar flow pressure the DN 50 handles around 2,000 m³/h — at 5 bar. As the pressure falls, so does the flow; towards the end hardly anything comes through.
And then the second part only begins: the venturi nozzle works only once the line is depressurised. How long it takes for the reading to drop below half the lower explosive limit depends on the condition of the line — incrustations and deposits keep releasing gas for a long time. Nobody can predict that precisely.
And the calculation applies to the section between the shut-off valves. Which section that is, only the operator knows.
Gas is a commodity. What stands in the line has been paid for by the operator; letting it burn costs that money a second time. Before an inspection a section is therefore usually pumped over — into an adjacent section, into storage, back into the grid.
That does not empty the line completely. Whatever remains after pumping over still has to come out before anyone opens the line. That is where flaring begins — not with a full line.
And there are cases where pumping over is not possible. Whether that applies is decided by the operator case by case. It cannot be judged from outside.
Without the second stage an ignitable mixture stays in the section. With it, the section can be cut.
What the equipment has to be capable of is set out in Article 17 — you will find that further up this page. Article 15 governs something else: whether flaring is allowed at all.
“Venting shall be prohibited, except in the circumstances provided for in this Article. Routine flaring shall be prohibited.”Article 15(1)
Both are permitted only in an emergency, during a malfunction — or where they are unavoidable and strictly necessary. The Regulation lists specific situations for this. Two of them bear directly on mobile flaring:
The proviso in point (k) is exactly the rule from the topic above — only as legal text. Rerouting comes before flaring.
“In addition to the conditions set out in paragraphs 2 and 3, flaring shall only be allowed where either re-injection, utilisation on-site, storage for later use or dispatch of the methane to a market are not feasible for reasons other than economic considerations.”Article 15(6)
The decisive words in that sentence are “other than economic considerations”: the fact that rerouting would cost more is expressly not accepted as a justification.
Conversely, flaring takes precedence over venting. Under paragraph 4, venting is only allowed where flaring is not technically feasible — because the flame cannot be ignited or sustained, because it would endanger safety, or because it would have worse environmental effects in terms of emissions. That justification has to be evidenced to the competent authority.
Annex III lists the information to be provided. For the quantity you need a measurement — that is what the volume measuring case is for.
The Regulation applies to the energy sector: production and processing of oil and fossil gas, wells, transmission and distribution of natural gas, underground storage, LNG facilities and coal mines (Article 1(2)). Biogas plants and industrial end users do not fall under it — different rules apply there.
This information reproduces the text of the Regulation and does not constitute legal advice.
Without these details neither the size nor the safety device can be determined.
We bring the propane cylinder ourselves when we carry out the job.
Whether the fire brigade has to be informed, whether permits are required, how the risk assessment turns out — that depends on your local conditions and internal rules. DGUV Information 203-090 is the guidance document for this. We can advise, but we cannot decide it for you.

Why AB Industrie
Many supply a flare. We supply the complete, verifiable flaring process — coordinated equipment from a single source, backed by service and spare parts.
Flare, volume metering case, pressure reduction station and accessories — coordinated with each other instead of individual parts from different suppliers. One contact for the whole process.
The Venturi nozzle actively draws the residual gas out of the line — well below 50 % LEL, down to the ppm range. Separate nitrogen purging can therefore be omitted.
Rent for a single project or buy permanently — you decide flexibly depending on how often you use it. Including briefing and delivery on request.
Up to 16 bar inlet pressure and around 2,000 m³/h (DN 50) — with the pressure reduction station even pipeline pressures up to 100 bar. Significantly more than common low-pressure flares.
Maintenance, repair and common spare parts directly from our workshop in Leipzig — without a detour via the manufacturer, quickly reachable and with briefing on request.
The volume metering case automatically logs flow rate and volume as a PDF — audit-proof for authorities, QA and audits under the EU Methane Regulation 2024/1787.
The IBEDA safety fittings must be tested at least once a year for tightness and safety against gas return — for the GRV50 in accordance with TRBS 1201, Table 2. This cannot be done on site: the unit is completely dismantled for it. Test and inspection equipment as well as the special jig for dismantling and assembly are located exclusively in our workshop in Plautstraße. We have already serviced and tested dozens of units there.
| Test step | DN 25 | DN 50 |
|---|---|---|
| up to the main shut-off valve | 8 bar | 24 bar |
| complete unit | 6 bar | 17 bar |
The test is documented. You receive the inspection report with the service — for your files, quality management and evidence towards the authorities.
And before every use? Article 17(3) of the EU Methane Regulation requires an inspection before every use for irregularly used flares. We brief your team on what to look out for.
The manufacturer distinguishes two levels. L1 you do yourself, right after the job. L2 is the annual service described above — the unit is completely dismantled for it.
Degassing hose and propane hose have a service life of eight years. Temperature, UV light, contact with media and heavy mechanical stress shorten it — which is why the visual check belongs in the L1 routine.
Silicone does not harm the flare — it harms the instruments: The unit itself does not care about silicone. What is at risk are the Ex and methane detectors running on the same job: siloxane vapours burn to silicon dioxide on the pellistor and settle as a glassy layer on the active surface. The sensor does not die, it just goes deaf — the instrument keeps running and reads low or nothing at all. Spray mist from several metres away is enough. So silicone spray does not belong in the same tool case or the same cab as the instrument. More on this in the guide
Important for your warranty: The annual service is classified by the manufacturer as level L2 and may only be carried out by KROHSE GmbH or one of its service partners — otherwise warranty and liability claims lapse immediately. We are an official sales and service partner of KROHSE GmbH for Germany; with us both remain in force. KROHSE partner list
About us
Frank Abraham founded AB Industrie Service in Leipzig in 2010 — after years of advising pipeline crews on site, in the trench, tool in hand. Nothing enters our range that we would not work with ourselves. For flaring equipment that is KROHSE: we are the official sales and service partner for Germany, advise before the sale, supply the right device with its accessories and service it later in our own workshop.
