Sedna shows specs for various condensing units, but one of them is the same one I just got at surpluscityliquidators.com. It's an FS4BI***** , running R410a and made by Nordyne and sold under Tappan, Maytag, Broan, Westinghouse & others (including privatelabeling for Sedna!) By itself it's a 22 SEER inverter drive variable speed communicating system that can throttle down to 40% of capacity or up to 118% of capacity. Apparently Sedna is piping the compressor discharge directly through a 20 tube evacuated tube collector that can handle 1000psi manifold pressure. I'm curious to see how this process, combined with a desuperheater, actually improves efficiency. If I learn more, I'll post!
