Clogged fog heater
« on: February 02, 2018, 11:15:07 am »

I had a cheap broken 700w fogger given to me to poke around on.  I spent $6 to replace the bad pump, then the heater clogged.  Tried pumping vinegar though it.... no help.  The fluid line is SS.  The ID is less than .043 (an .042 drill bit will not go).  Two .018 wires will fit, so I am guessing .038-ish.  90-ish psi rubber tipped blower with a "high-pitched fart" seal won't pass air.

The aluminum block is 3 1/4" long and 1 5/8" w.  From what I gather, the tube snakes thru the block, so I estimated between 4 - 5" of length inside the block.  The exposed part of the tube is about 7" with a couple of loop bends.

I have been able to snake an .018 wire about 1/2" in to the block on the entrance end, and about an inch on the exit end.  I presume to the first internal turns. 

I don't want to buy a fog machine (I haven't used one at a gig in a dozen years - alarms and all), or buy a heater.  This is a project.

Would an ultrasonic cleaner breakup the blockage?  Will the cleaning solution (which I assume has to contact the blockage for the waves to do their thing) be able to travel up such a small channel (even on the exit end)?

I would consider buying a cleaner if it will unclog the heater, because I could then use it to clean the wife's jewelry and maybe other stuff too.  But I would not buy it to clean other stuff if it won't do the trick for the heater.

I thought about taking it to a jewelry store, but I don't know if they would do it.

Final question:  Any danger to ceramic coating on the elements?

Thanks,
David

I have used a syringe and CLR successfully a number of times.
Syringe on the inlet side with a silicon tube over it sealed with a couple of small zip ties.
Pressured up a little in a catch pan over night should get it cleared.
I have used this method a lot and restored heaters to like new condition.

CLR?  That crossed my mind.  Good idea about the pressured sirringe.

Thanks.

Success.  Same principle, but I went in reverse.  This heater had a 1/8 straight pipe on the exit.  I got a fem-fem and a plug.  Teflon taped them up.  Screwed on the coupler loosely and filled with clr then screwed in the plug then tightened them to act as a hydraulic piston.  Started getting output almost instantly followed by flakes of stuff.  Several refills of clr, then vinegar, then distilled water.  I tjink tjis metjod would fix any heater clog as long as it has threaded inlet or outlet.

Thanks to Jason for the pressure concept.

You can also chuck a guitar string up into a drill and run it inside the tube. Sometimes that action will get it unplugged.

CLR = Calcium Lime Rust remover. Typically found in any big box/grocery/hardware store here in the States.

I picked up a couple used Chauvet RGB Geysers.  One has developed a clogged heater... oddly enough, this happened while I was running through a 50/50 Distilled Water/White Vinegar cleaning cycle.

I took the unit apart and verified there were no clogs leading up to the inlet of the heater. I also verified the pump was working.

I tried running a guitar string (tried E,  A and D) through the heater, but it appears the path takes a lot of twists and turns.  I ran the string into the inlet about 18" or so before I got scared of breaking it off inside the heater.  It never did make it all the way through.

I tried tried forcing air, water, and vinegar into the inlet with a squeeze bulb, but never got it to come out of the outlet.

So far, none of this has improved the situation.

The last thing for me to try (that I can think of) is what was mentioned here- to use CLR.  I pickup up some CLR, but it states on the bottle "Do not use on steam machines".  For those of you who have used CLR with success, have you had any problems? Is there anything else worth trying?

Just run distilled water through it after the CLR. You'll be fine.

The warning is for idiots who would put CLR in a steamer and try to huff it.

Update: I've been trying to run CLR through it for 4 days. The most I can get through is about 1 drop a day. I have a syringe filled with CLR attached to the inlet. Pressure is being applied to the plunger to force liquid into the inlet. I've tried putting a tire pump on the inlet while applying 120 lbs of air pressure.  I can't feel the air coming out the other side.  I've tried the guitar string many times, but it eventually reaches a point where it just won't go any further.

I'm beginning to think this one is a lost cause and I should just get a new heater.

Got any way to apply vacuum and draw cleaner backwards.

I think I had a couple of fogger threads.  IIRC this one I got cleared by making a "hydraulic" pump with a brass fitting combo that would attach to the exit end and pushed the CLR through and the scale out.  So good results.  The other thread (fogger) I didn't have any luck.  Win some, lose some.

ADJ, Chauvet, and other "name brand" manufacturers sell parts.  Pumps for generics are available on Ebay and Amazon if the number on them is present.  Often, they are simply sold by heater wattage and comparing inlet and outlet sizes, and voltage.

Never was able to get the heater line to clear. Ended up buying a new heater core and a few misc fitting parts from Chauvet Parts. Got it up and running.

i guess that was cost effective instead of buying a brand new unit :D
sometimes we like to fix things although the repair route is more costly
