InnSep has developed a self-cleaning filter that can replace today’s separators. With support from Innovation Norway, the technology will conquer the restaurant industry.
The Trondheim-based company’s solution is currently used to purify exhaust gas on ships, air from compressors and gases in the offshore industry. With grants from Innovation Norway, the filter system will now find its way into restaurant kitchens to increase fire safety.
Multiple filter tests
Grease deposits in ventilation ducts can become several centimetres thick over time and highly flammable. In the event of a fire in such ventilation systems, the temperature often becomes so high that the ducts melt and collapse, causing the fire to spread quickly. Another problem is that the grease deposits can become so great that the ventilation ducts fall down due to the extra weight.
“We have tested the filter in our separator using a variety of frying oils and water, and no drops or particles have managed to get through – not even the smell. The process is very efficient”, says CEO of InnSep, Sondre Klæboe Jacobsen.
The solution first became interesting for the company called Mælen Blikk og Ventilasjon which was working on a project nearby. InnSep then got in touch with property and restaurant owners who are required to follow fire regulations and meet these challenges.
Planning mass production
In 2021, full-scale prototypes will be tested in an innovation project supported by Innovation Norway. The Trondheim-based company has received several different start-up and development grants.
“Without Innovation Norway, we would not have been able to focus on the development of the technology or pay salaries, which has been absolutely necessary for the progress of the project. We would have had to postpone the process and give our competitors the opportunity to take the market away from us”, says Klæboe Jacobsen.
InnSep is planning mass production together with the machining company PTM industries when the final commercial version is ready.
“In Norway alone, there are between 5000 and 10,000 restaurants that require our technology. Today’s grease removal systems are composed of filters, UV lights, charcoal filters and rotating discs that make a lot of noise, and they can cost hundreds of thousands of kroner. We will offer a solution at a lower price and with a fraction of the operating costs”, says Klæboe Jacobsen.
Own patent strategy
The separation principle, called Lynx, is mainly based on a rotating, porous disc that all gas/liquid meets. The droplets that try to get through the disc are collected and thrown out by the centrifugal forces. The dry and clean gas is not affected and passes freely through the disc.
The Lynx principle is protected with several patents and InnSep developed its own patent strategy through a pilot project. This has resulted in three new patents that secure all aspects of the innovation and application.
