Chauvet Haze 1dx Spitting


posty07

Recommended Posts

Hi All,

 

Recently purchased a hurricane 1dx listed as spares or repair due to not doing anything. Turns out the overheating sensor had just clicked - annoyingly it's a manual reset type..

 

So after resetting, it started heating up and the pump/air pump kicks in as it should and it does start producing a nice haze. However it's spitting a lot whether on low med or high setting

 

Things I've tried/tested

- made sure the main pump works fine, it does

- checked air pump

- checked the thermocouple temp measured with a multimeter

- cleaned with a mix of 50/50 deionised and distilled vinegar for around 30 mins.

 

The overheating sensor does kick in again if it's left plugged in without pumping fluid for around 30 mins

 

I'm using actual Chauvet haze fluid so I'm pretty certain it's not that..

 

Any ideas?

 

Thanks!

If this was a Unique or Tourhazer, then spitting is always caused by the Air Pump which may work perfectly at full output but at low output may become sporadic due to the inside getting soaked in condensed haze. This is a common problem and we often change the A. Pumps and keep loads in stock for this reason. However I don't know the Chauvet Hazer at all so ignore this !! Also we only recommend flushing them (Look & Smoke Factory machines) thru with Distilled Water only (not de-ionised) and certainly no vinegar.

Hi both, thanks for the advice!

 

I'd agree it's probably getting too hot but what I find odd is that the thermocouple reads at 300 degrees c (by probing with a mm) when it switches off then goes back on at around 260.. does that sound a bit hot? Do you know if thermocouples are pretty universal..? Reckon this might work? https://uk.rs-online.com/web/p/thermocouples/6212170/

 

Very possibly could be a bad air pump, it's a few years old and the pump runs almost constantly, reckon it's worth replacing? What pumps do your machines use?

Thermocouples are "universal" if and only if they are the correct combination of metals! The one you link to is a "Type K" thermocouple, so it will have the same voltage per unit temperature as every other Type K thermocouple - but very different to a Type T thermocouple!https://www.tc.co.uk/thermocouple-information/thermocouple-data.html#materialslists some common type letters. Note this also applies to the temperature option on your multimeter - it will only give correct temperatures with the thermocouple type is it programmed for (or selected, if you have the option).

The one you linked to has an exposed junction, i.e. the end of the thermocouple (where the sensing happens) is bare wire. If you short it to ground you won't get a temperature reading! More expensive types often have an electrical insulator (but thermally conductive) over them so they can be used touching metallic components (like the heater block you are trying to regulate).
