I think you’re thinking of = my installation – Mark has Fluidyne (or knockoff) = unit.

You got a great price on an E54 = dual core.  Are all the fins in good condition?  They are = relatively easily damaged.  That 182 unit should handle roughly the = same heat load as = mine – so about half the requirement for a 2-rotor.
