Lgem logo - Derisking with the AlgaeHUB – Start today

We can readily demonstrate and share the whole experience of our newest technologies at our ground-breaking AlgaeHUB®. Because we know investment risk reduction is a crucial success factor for investors in a healthy algae industry. In our cutting-edge facility, we offer customers the possibility to validate their business case on a commercially relevant scale before making significant investments. A must-have for any scale-up, testing is supervised and executed by an expert team of us or your operators, whichever you prefer. 

Of course, our ground-breaking AlgaeHUB® offers a lot more than a pilot-scale test case for your desired production levels. You can experience and approve all our tried and tested production units here. Operational units range from the Lab-25 tubular glass PBR specifically designed for laboratory research and ultra-pure starter culture production to our full-scale Helios- and Entos-units in shiny working order. Read more about them here.

You can experience all aspects of our tubular photobioreactor design. Find out why we switched from PVC to glass to bring you Lgem’s renowned design: it offers a more stable light transmission, better chemical resistance, increased ease of reparability and a considerably improved life span under field conditions. 

We also found that conventional production systems use a lot of power and aeration for circulation to prevent biofouling and oxygen build-up. Two of our patented technologies, Wavywind® and Bubblebrush®, were incorporated into the photobioreactors to address this. 

Air moving through the glass tubes removes oxygen. It supplies carbon dioxide evenly over the whole tubular helix at 100 Watts per 1,000 litres of culture or a mere tenth of the energy input of conventional tubular systems. With volumes ranging from 25 to about 45,000 litres, our designs include a circulation tank, pump set, pH/temperature probe, switch cabinet and cloud-based measurement and control. No centrifugal pumps are needed because the moving air can propel the entire system. That means our PBR systems can also operate with just an air source and without any moving parts, which is particularly interesting for aquaculture that produces fragile species. We’d love to show you.

Admire the geometry and light distribution of our range of intelligent solutions, thanks to factors like the diameter, length, inclination and arrangement of the tubes. Feel the rigidity, surface properties and ease of connectivity of our materials and systems. Understand the exceptional levels of hygiene compared to any other tubular system currently on the market, thanks to the attention to detail in our weld seams, dead zones and seals of mechanical couplings, cleanability, chemical resistance and heat tolerance of our structures. 

We have standardly equipped our PBRs with sensors for all essential process parameters; pH, temperature, light intensity and water level. Our AlgaeHUB® truly is an experience centre for a close encounter with our products, from practical examples and hands-on understanding of mass transfer and control to mixing and energy consumptio. 

Beware, though: seeing is believing.
