I promise I'll be quiet through February after this one Peter. :-)
If Pyro supplies anciliary 3 phase AC equipment (such as compressors and nitrogen generators etc) to another country that has a different voltage and frequency grid (220V/60Hz), I'm guessing there would be transformers and frequency convertors involved in the mix.
-- wouldn't this add to the cost of the package (looking at it from the customers perspective) - they could source these locally, and cheaper.
-- would spares for these equipments be supplied by Pyro (since Pyro isnt the OEM for these).
