Dry gas seals
Protection of contact-free gas seals in offshore turbine compressors
EagleBurgmann took an exclusive licence in 2015 and put the unit into service in 2016, after a pressure test to 330 bar.
InnSep AS, Trondheim, Norway
InnSep AS builds the Lynx separator, a rotating filter that takes liquid out of a gas stream without clogging and without added pressure drop. The same machine has protected compressor seals offshore, cleaned exhaust gas on ships, and taken grease out of commercial kitchen air.

On the record
EagleBurgmann holds an exclusive licence for dry gas seal protection from 2015. Flebu International signed an exclusive sales agreement for ship exhaust gas recirculation in 2018. Innovation Norway, the Norwegian Research Council and the NTNU Discovery Fund funded the development. Chemical Engineering magazine covered the separator in October 2015.



NTNUThe technology
A conventional filter fills up. Pressure drop rises across it, and someone has to swap it. The Lynx separator turns, and the rotation clears the mesh continuously.
The same principle is scaled to the duty. The Lynx 150 was built for very small liquid volumes, for dry gas seal protection. The Lynx 250 is the full gas/liquid separator used offshore and in commercial kitchens. The technology is patented.
A gas stream carrying liquid droplets enters the housing and meets a filter that is already turning. The housing is hermetically sealed, with no shaft passing through the wall.
Droplets are caught in the mesh. The rotation throws the captured liquid outwards to the wall before it can build up, so the filter never fills.
The liquid runs down into a separate chamber and is drained. The gas leaves dry, at the same pressure it would have had without the unit in the line.
Value areas
Each area below carries the highest step it has reached and the year it reached it. Four areas were licensed or sold and put into use by another company. The spread is the honest picture, and it is what makes the four credible.
Protection of contact-free gas seals in offshore turbine compressors
EagleBurgmann took an exclusive licence in 2015 and put the unit into service in 2016, after a pressure test to 330 bar.
Removal of grease from kitchen exhaust air
Two years of operation without downtime in a Trondheim restaurant, then a commercial launch in 2023 and a Norwegian industry award in 2025.
Cleaning of recirculated exhaust gas on marine engines
Flebu International took an exclusive sales agreement in 2018. In 2023 InnSep stated that the system was in use with Norwegian partners.
Removal of liquid from compressed air, before and after the compressor
In 2023 InnSep stated that the separator was in use with Norwegian partners for cleaning compressed air used in seismic operations.
Gas/liquid separation on offshore installations, Lynx 250
The Lynx 250 was tested to 90 bar at the Statoil high pressure facility at Rotvoll in 2016, PED certified, and presented at TEKNA in Stavanger the same year.
SOx and NOx removal from ship exhaust
A project with INVENTAS and the MAROFF programme from 2014. Diesel exhaust was cleaned in a trial at the EagleBurgmann Norway laboratory in 2015.
Preconditioning of ventilation air ahead of a heat exchanger
SkatteFUNN awarded R&D support in 2023 for a project on whether the Lynx principle can keep heat exchangers clean. InnSep carried the project out as applied for.
Separation without gravity, for spacecraft and habitats
InnSep described a separator design for weightlessness in 2022 and reached out to space organisations for collaboration.
Evidence
At the El Rincon restaurant in Trondheim, two ventilation ducts were fed from the same kitchen hood. One duct had a Lynx separator installed behind the hood filter. The other did not. Cameras recorded both.
The duct without a Lynx separator showed a clear grease deposit after six weeks. The duct with one showed no build-up and no detectable residue after two years of service, with no downtime. InnSep published the comparison on 24 May 2023.

Openings
InnSep is opening the technology to partners and investors. The form is not fixed. It depends on the area, and on who is on the other side of the table.
The company would rather hear what you have in mind than tell you what is on offer. Start with a conversation.
Open now
The kitchen separator has been sold and installed in Norway since 2023, and Tovenco carries it in Sweden today. Lynx Kitchen is looking for larger partners who can take it further, first in Sweden and Denmark.
The category does not matter. A contractor moving into commercial kitchens counts, and so does a seller who wants a larger share of the market and of the value chain.
Lynx Kitchen is the contract party for the kitchen system.
Open now
The same separator has been licensed, sold and tested across seven other markets, from dry gas seals offshore to exhaust gas recirculation on ships. Each of them has a history, a year, and a source in the archive.
What an investor would buy is not settled. Shares, a stake in one area, or a licence are all open. That answer should come out of the first conversations, not out of an assumption made in advance.
InnSep is the contract party for everything other than the kitchen system.
One line about which area interests you is enough to start. Call or write.
The site does not answer what a licence costs, what a share would be worth, or how royalties would work. Those belong in the conversation, where your own view of the model matters as much as ours.
The company
InnSep AS is a spinout from the Department of Energy and Process Engineering at NTNU, the Norwegian University of Science and Technology in Trondheim. The company was established in 2011 to develop a scalable gas/liquid separator for removing droplets from a gas stream.
The Lynx concept was awarded the SMN1 Innovation Prize in 2011, nominated for the COMS Young Technology Award in 2012, and nominated for the Norwegian Tech Award in 2015. Development was funded by Innovation Norway, the NTNU Discovery Fund and the Norwegian Research Council.

Questions and answers
The Lynx separator is a gas/liquid separator built by InnSep AS in Trondheim, Norway. It removes liquid droplets from a gas stream using a filter that rotates. InnSep AS was established in 2011 as a spinout from the Department of Energy and Process Engineering at NTNU, the Norwegian University of Science and Technology.
Wet gas passes through a filter that is turning. The mesh catches the liquid droplets, and the rotation throws the captured liquid outwards to the wall, where it drains into a separate chamber. Because the mesh is cleared continuously, it does not clog, and the pressure drop across the unit does not rise as it runs.
A conventional separator relies on volume and gravity, and a static filter fills up over time. The Lynx separator uses rotation instead, so it takes 50 to 70 per cent less volume than comparable gas/liquid separators, and InnSep has reported separation down to 0.3 micron. At the Rotvoll test facility in 2016 the Lynx 250 lost less than a third of the efficiency a conventional separator loses as pressure rises to 90 bar.
In eight value areas. Four reached operation: dry gas seal protection on offshore compressors, licensed to EagleBurgmann in 2015; grease removal in commercial kitchens, launched in 2023; exhaust gas recirculation on ships, sold through Flebu International from 2018; and compressed air for seismic operations. The other four are at pilot, laboratory or concept level.
Yes. The Lynx 250 was tested at the Statoil high pressure test facility at Rotvoll in Trondheim in 2016, where efficiency and K-factor were confirmed up to 90 bar. The unit built for dry gas seal protection was pressure tested to 330 bar at EagleBurgmann Norway in 2016. The Lynx 250 is PED certified.
InnSep AS is a Norwegian company with its head office at Sluppenveien 11 in Trondheim, Norway. It was established in 2011 as a spinout from the Department of Energy and Process Engineering at NTNU, the Norwegian University of Science and Technology. Sondre K. Jacobsen is CEO and Roar S. Andersen is chairman.
Two things. Lynx Kitchen is looking for distribution partners in Sweden and Denmark who want to scale up and have a network in that market. For the seven other value areas, InnSep AS is open to investors and partners. The form is not fixed, and the company would rather start with a conversation than with a term sheet.
That is the main case InnSep has described. Because it needs 50 to 70 per cent less volume than a comparable separator, it fits where a conventional unit would not. In 2016 InnSep set out five retrofit positions: after a main separator, ahead of rotating equipment, in parallel for de-bottlenecking, as replacement internals, and as a replacement separator.
