Tontsa Posted March 11, 2005 Share Posted March 11, 2005 Hi, I came across with this question when I checked the list of technical equipments of a theatre we're going to do a show at. It said that they have a cracker there and I know it's almost the same as a hazer but is there some kind of difference between them? Link to comment Share on other sites More sharing options...
johnhuson Posted March 11, 2005 Share Posted March 11, 2005 A cracker is a machine which uses a mineral oil which then has compressed air blown through it, the result of the 'cracking' is a very fine mist of oil droplets which produces a haze. Crackers in my opinion produce a much nicer haze to water based machines, which are essentially a smoke machine with fans and a different fluid. The haze from a cracker is less noticable until you put beams through it, it disperses better so there are less clouds, and it hangs around for a lot longer than water based machines.

The haze from a cracker is less noticable until you put beams through it, it disperses better so there are less clouds, and it hangs around for a lot longer than water based machines.Agreed - the haze from a proper cracker (e.g. a Cirro machine) is far superior to that from a water-based smoke-machine-with-a-fan-on-the-front hazer (e.g. Jem or LeMaitre). It 'hangs' better, and is much finer. The only problem with it is that, over time, it has a habit of leaving a thin oily residue over things like lenses and colour - if you're using one long-term, it's something to consider. The only water-based hazer that I've used and liked is the Unique by Look Solutions - about as close as you can get to an oil cracker without actually being one!

We use two of them in Paradiso, Amsterdam and they're fantastic for both bands and dancenights. On low-level they're quite like DF-50 cracker and on full output like any other mid-sized smoke machine, but giving a far nicer haze that stays in the air longer. If anyone is thinking about what smoke machine to buy I would seriously advice to check these out. Link to comment Share on other sites More sharing options...
SparkySteve Posted March 14, 2005 Share Posted March 14, 2005 crackers are also better on tv... they produce thousands of tiny 'flat disc' like droplets in the air, when looking acrros these said 'flat discs' you can't really see the haze... ideal for close up sots etc on tv. But then looking at an angle you catch the flat area of the disc and therefore can see the haze. I think this explains what I mean... hope it helps Link to comment Share on other sites More sharing options...
LegendTheatrical Posted March 14, 2005 Share Posted March 14, 2005 In my experience, the cracker hazer is much better, in performance an reliability especially. I would agree completely with Gareth. The 2 best hazers I have seen are the Swefog, www.swefog.com or the DF-50 www.reelefx.com. Link to comment Share on other sites More sharing options...
johnhuson Posted March 19, 2005 Share Posted March 19, 2005 Would also like to add the Cirro Strata CS6 hazers to the list of good hazers (call me biased if you like as we stock them in our hire stock). One feature which makes it stand out for me is the ability to separate the compressor from the tank to reduce noise. Especially useful in TV/Theatre environments.

(my school is paranoid about safety - I once had to wait for a week before I could have a smoke machine that I hired back while they did a full health and safety check on it :)). Like, in the long term the thin oily residue won't damage anything or start any fires will it? Link to comment Share on other sites More sharing options...
Tomo Posted April 17, 2005 Share Posted April 17, 2005 The residue will need cleaning off at regular intervals - how regular depends how much haze you use of course! I have heard about health concerns, but I'd class them as the 'paranoid' variety rather than anything serious. A small amount of dryness of eyes and throat is the worst I've come across - but that was in people with existing conditions making them more susceptible. Don't drink the fluid though! As to fire hazards - never heard any concern about the residue itself, but the stuff means that more dust will collect on any surfaces - this may become a fire issue if you don't clean them every few years!

I'm sure this is paranoid but our hall isn't massive so I'd be using it in quite a confined space. Link to comment Share on other sites More sharing options...
TallPaul Posted April 17, 2005 Share Posted April 17, 2005 No, they won't get wet. By "water based" this simply means that the fluid is mostly water, and is similar to 'standard' smoke fluid. It is not a spray of water that comes out of the machine or anything, you should be ok! Link to comment Share on other sites More sharing options...
nickb12345 Posted April 17, 2005 Share Posted April 17, 2005 Just dont spill the oil for the cracker... you will be able to skate across your stage on it if you do Nick Link to comment Share on other sites More sharing options...
ben.suffolk Posted April 18, 2005 Share Posted April 18, 2005 Do spend the extra on the oil based fluid, rather than using a water based fluid, its a much much better haze. Ben Link to comment Share on other sites More sharing options...
730 doors Posted April 18, 2005 Share Posted April 18, 2005 has anyone had experience of the antari "fazers" which claim to be able to produce fog (smoke) and haze? The look like they're a conventional smoke machine with added fans and a venty on the front. Do they produce a worthwhile haze or is it just like using a smoke macine with a fan behind it?
