Digi-Key stocks alternistors that are rated for inductive loads.  They are 
rated 40 amps, 120 VAC, and should handle 18 Amps each with considerable 
ease.  You would probably have to run a good line filter between the 
alternistor and load.  Also perhaps some ferrite or iron powder RF inductors 
in the circuit to help clip and really HF transients.  Perhaps even a few 
small air core chokes at the front end.

I think Dave Sharp has considerable experience with these types of power IC 
circuits and perhaps would be a good source to help with the initial design 
work in this area.
