newbie just getting set-up

[fragglerock]

I have a Caswell LCD anodizing set-up that I'm getting set-up , in the manual it says to put the 200w adjustable heater in the anodizing tank,,why? It says the tank should operate at 60-75f, if that is so why would you need the heater in this tank?

You need to remember where they are at. A heater is only needed in the anodize tank if the electrolyte temp falls below 60 degrees. Other than that it can be left out.

thank you. I'm in San Diego Ca. so I think I can leave out the heater in the anodize tank.

Then you may have to figure a way to cool the tank.

Maintaining tank temperatures is one of the most important tasks associated with setting up an ano line. Here are the temps I shoot for:
Ano: 68F to 70F
Stripper: ~70F
De-Smut: 100F to 120F
SP degreaser: ~140F
Dye: 138F to 142F
Sealer: Boiling

Thank you so much for this info. What is the easy'st way to keep the ano tank cool? I have limited space and limited funds.

Some have their tank in a larger tank and use ice to cool the tank. A fan blowing over the tank. Can be difficult to regulate temp. I use a $100 110V AC window unit blowing into a cooling box made of scrap materials. (pics in album) Acidrain has a homemade heat exchanger to control temp and then there is the aquarium chiller for about $400. The heat exchangers or chillers need a pump to circulate the electrolyte which can eliminate the need for air pumps to agitate the electrolyte but one rated for acid start out around $200 and go up unless you can find one on Ebay.

Thanks again. this is a great forum, as soon as I anodize my first piece I'll post some picture's. I'll keep good notes so that if I have any more problems I know who to ask and have enough info to ask the right question.
