Cooling of home/D-I-Y anodising baths

Disambiguation: Please see also --

Topic 36775, "Best way to cool anodizing tanks?"

Topic 51573, "Hard anodizing chiller sizing"


Q. Sir,
I am a home type anodiser making anodised labels. I want to know how to cool the electrolyte which is cost effective as well as easy to operate. I have got 25 liters capacity tank and having lead lining. After I start anodising immediately bath temp. rises and needs immediate cooling. Is it economically viable to use 25 l. tank or should I increase the tank size?
Thanks.

Hey there,
I have a couple trouble shooting questions and a simple yet crude way to maybe cool the tank. If you are able to anodize what you need in a 25 L container, I would stick with that size.
What kind of anodizing are you doing? Often times there are temperature tolerances in anodizing, are you within that tolerance?
Do you have any agitation or circulation within the tank? Circulation in the tank may help keep a constant temperature.
Now for the crude suggestion: get a larger bucket and fill it with cool water. I kind of think of a bomb calorimeter with a water jacket. It may take some trial runs to get the temperature right and the water jacket may need some circulation or temperature control. But I think that maybe the easiest solution.

Hi.
I've seen some home anodizers cool their tank by placing several 'ice packed mineral water bottle ' directly into the anodizing tanks. The mineral water bottles were placed in the chiller in the home refrigerator over night....ready for use the next morning.Good Luck.

Sir,
at present if I start the anodising I take plastic bottle filled with water and freeze it and dip in the solution. During anodising I agitate the solution manually. So it serves the purpose to certain extent. Main problem is every time you have to insert fresh bottle and take out old bottle. Which is hazardous, isn't it. So I want a workable, economic and hazard-less idea.
