Helix 5000 by Orphek adds a twist on the needle wheel with a spinning “spring wheel”
By Jake Adams on Mar 18, 2014
The Helix 5000 protein skimmer from Orphek was first announced and revealed at MACNA but there’s been a whole lotta tinkering on the design in the intervening months. While the shape of the body and the pump are highly reminiscent of the RLSS skimmers from a couple years back, a handful of notable features help the Orphek Helix 5000 stand out.
Initially the Helix 5000 was a complete cone skimmer with a nifty ‘Helix’ part of the diffuser plate which encouraged the erupting bubbles to take on a circular path. along those same lines Orphek is upping the ante with an internal impeller, both above and below the diffuser plate. Again in an effort to put a real spin on the air water mixture in order to increase contact time, the impeller below the bubble plate is pushed by the flow of the incoming water, which is now offset from center to really leverage angular momentum.
