Where as conventional tubular PBRs are completely filled with water, GemTubes™ have two fases (gas and liquid). LGem’s unique and patented process in combination with LGem design, allows for much lower energy consumption than in conventional tubular PBRs wihout compromise. LGem PBR’s are the world standard when it comes to low energy need, the prevention of bio-fouling, good mass-transfer getting rid of oxygen without loss of CO2.
On the material side we have made huge innovations in both cost reduction as in hygiene and scalability, thanks to our partner GF+. For instance we use innovative materials. Like PP- tri-clamps that contribute to easy installation and outstanding hygiene. LGem GemTubes can all be constructed to allow for heat treatment at 70C or 158F. Important for food production.
LGem technology can be adapted to your individual PBR plant design, even for large scale operations. Up-scaling is unlimited and because of the modular design of our systems, ths allows us to copy paste.
A major operational innovation is the fact that our systems can run in two modes, air only or air assisted with a liquidpump. This unique option makes GemTube systems suitable for the most fragile species like Rhodamonas and Dunaliella as well as for species that precipitate easy.
