Roller processors for Ilfochrome?

[MMfoto]

Are there any benefits to using a table top roller processor(Cap40, ICP, IWD) for Ilfochrome processing over a drum processor? This is for moderate to heavy occasional use, not commercial. The drum processors are much more common and I would imagine require much less service. Are there pro's and con's to either?

Hey, something I know about!
I use the ICP42 for up to 16x20, and the Jobo CPP2 for 20x24. The ICP is great for "production" runs, when you need many prints and/or different sizes, and not worry too much about "mistakes." One shot of the chems yields a lot of prints. I found it's easy to clean, and in 12 years have had no failures.
The drum processing requires a lot more water, and more critical attention, but yields the same quality results. You must dry the drums between processes, measure new chems, etc... so the through-put is not as great.
Hope this helps.

I am in touch with a photographer in Vancouver with a Cap 40 for sell if anyone is interested pm me and I will forward the name and address.

I had never considered that the drums have to be dried between use. I suppose if you had two or three drums then that wouldn't slow you down too much. I suppose size constraints would matter most as I'd have to have a drum processore anyways if I wanted to print larger than 16x20", or whatever the maximum size of your unit is.

Do you save a lot on chemistry when using your ICP42?

I won't be up and running for probably six months, but I'm trying to learn and plan ahead until then. I'm sure I'll have a bunch more questions!

Thanks DT.

I have used drums for Ilfochrome processing with great success. As with colour and monochrome use the drums have to be washed, and dried between uses, but drying means removing drops of water, and not “bone” dry. This is necessary to avoid cross contamination and comprises a careful rise and dry, as opposed to 40 minutes in the dishwasher.

On paper, the P3.5 yields 26 8x10's (2080 si) per two liters of mix.
In practice this is what I get per mix:
ICP42 with 2ltr mix - 11 16x20's; 20 11x14's; 35-40 8x10's
The 20x24 drum on the CPP2 per 2ltr mix: 6 20x24's, using the 50% partial re-use method.
