I recently bought a used CPE-2 Jobo rotary processor and to date, only shoot B&W . The difficulty I have is trying to get the bath to 20C for B&W processing as I have to run my A/C A LOT to get 22-23C in the apartment and my "cold" tap wate r is 30C. And doesn't get much lower in "winter." (I'm in FL).
I have put ice in the bath, and keep a couple gallons in the fridge for bath wat er, but the processor brings the water up to processing temperature quickly, and then the temp just quickly goes up on its own toward room temp.
Anybody have any tricks to maintain a lower-than-room-temperature bath? I've re ad some references (Adams, maybe?) in which the author is adamant about developi ng B&W at the recommended temperatures. Besides shortened developing time, is t here really any detrimental effects to processing B&W film at higher temps. (I' m using XTOL and T-MAX 100).
BTW, my processor maintains temp well if the set temp is above room temp.
