I see your in BC, we just installed generators at all of our breweries from Carbonic Systems here in Washington. I and all of the brewers i have spoken with are very happy with their performance, pretty much worry free. From what i understand they have a unique design that improves their lifespan and requires less maintenance than others on the market. Not sure if they do international business, but i highly recommend them. Contact Jessie McLaughlin for details on them. I will PM you with contact info.
