These new Deltec skimmers have been spotted in operation. Aquarama had the TC3070 and SC2560 model skimmers up and running.
Additionally, Deltec has released a little explanation as to how exactly their new bubble chambers work and why they are superior to other skimmers on the market (click on text below to be taken to original article):
The Deltec TC skimmer range features a unique, patented twin chamber system which in combination with the new Deltec skimmer pump offers a number of advantages:
The Deltec TC system allows extremely high water flow through the skimmer without causing turbulence. Turbulent flow in the riser tube can draw waste back into the water column and reduce efficiency.
The Deltec TC system pressurizes the suction side of the skimmer pump increasing pump performance.
