    Hass Intellifaucet - W O W

    I visited a darkroom yesterday which had one of these. Holy crap. I remember seeing the ads in magazines and it always looked like a nifty thing, but I'd never seen one in action before. I hadn't ever given much thought to how it actually works before, but it does.

    I've had a model K250 installed for years.* It's one of the single most useful pieces of darkroom equipment I own.

    My previous darkroom was in a desert climate where ice cube tempering was the norm. When I moved to a cooler climate I vowed never again. Instead of ambient 84F/29C degrees in summer I now have 67F/19C degrees or less. It's such a precision instrument that even at 67F/19C degrees it can successfully hold a 68F/20C degree output. Amazing.

    However, for anyone considering the investment it's a good idea to figure out how many months each year your ambient is below 68F/20C. Or below whatever your own baseline processing temperature might be. The unit would not have been of much use if that threshold was only met for a few months out of each full year.

    * There is also a much less expensive darkroom-specific model D250 for the more budget-oriented users.

    They are great. I happened into one a couple of years ago in responding to a CL ad for something else. All the buzzing and clicking of the stepper motors is a little disconcerting at first. But they work really well, and it really beats fiddling with a single-handle temp controller.
    Another big plus is that Hass is still in business and very responsive to email questions.

    I think it's too complicated up front for me even if I could afford one. You kind of have to put together a "water board" with filters and stuff. I ain't no plumber and I don't know anything about flow rates, bleeding, priming, pressure etc. Plus I'm so used to endlessly fiddling with the taps that I'd feel downright spoiled having one of these awesome things. I just thought I'd give the company a plug anyway. I sort of understand how the valve mechanism works, but it still blows my mind how steady this thing held the temperature. It just didn't budge.

    Very interesting piece of technology, at a very uninteresting price (to me anyway). $1100 plus shipping will buy me a lot of film and paper. Using ice cubes out of the fridge and hot water out of my tap has worked just fine for me for a long time.

    Observing it in action, there seems to be an attenuation behavior programmed into the software. At least it looks that way to me watching it work.

    If, say, a hot water tap is opened anywhere else in the house, thus causing a sudden drop in hot line pressure, the software will instantly compensate by intentionally pushing the output temperature over the set point by cutting the cold water flow, thus negating the unexpected cold water surge. It will then swing back and forth like a pendulum until settling back at that set point at a new reduced flow rate.

    The net effect is that a larger volume of tempered water being fed by the unit never changes temperature. The unit itself "absorbed" the temperature anomaly completely. Pretty cool stuff...

    I read somewhere once that Intellifaucets were installed on those old Kodachrome K-Lab processors, but I don't know if that's true.

    [Edit: Yes, it is true. Kodak Publication No. TG2044-1 (04/06/1999) directly references procedures utilizing an Intellifaucet. (See pp. 4, 9, 37 and 38.) Note that the Intellifaucet has been on the market since 1987.]

    There is also a much less expensive darkroom-specific model D250 for the more budget-oriented users.

    I have used an D250 for some years now, and it's a real time saver:

    i know what you mean moms.
    if i had the $$ it would be a nice toy to own.
    i think i have thje broke cobbler's version of the same thing
    or used to .. maybe 20 years ago .. now i just use a faucet
    with hot and cold knobs and a thermometer .. it seems to work OK
    for the time being, that said, i am always in awe of nice darkroom set-ups ..
