I have an MDG Atmosphere that is being really finicky. This is supposed to be one of the best hazers that is available, but ours has never been reliable. We are now two weeks into a 12-14 week run of Les Miserables and I can't get consistent output from it from night to night. I have taken it to be serviced, and it worked great for two performances and then we were back to not so great performance. It really has me miffed. I have checked all the settings, and we haven't changed anything from the nights it worked to now. I suppose I should mention that this particular machine has a serial number under 10, I think it might even be under 5. Tonight was the worst yet, had the regulator freeze up, which is a symptom of liquid CO2 getting drawn from the tank. This is not I good thing, may mean my tank has gone bad. But we have two tanks, and even with the other tanks we still have the same output issues. I was hoping someone might have some input. Other than that, I am trying to convince the theatre we should just get a new machine. We have been having these issues all season, and it seems to be getting progressively worse even after professional service.
