    Ericson 32-3 Refrigeration

    The Ericson brochure claims the 32-3 icebox is a "6 cubic foot insulated ice box with insulated top and lid". I believe them regarding the insulation, my block ice lasts all weekend.

    To add electric refrigeration, the price of the Isotherm VE150 is tempting, but it says it is for refrigerating 5.3 cubic feet. My goal is to keep a 12 pack of beer and condiments cold between visits (not extended cruising). I'll still put a bag of ice cubes in when I am aboard, and still use block ice when I am cruising for a few days.

    I'm wondering if the 5.3 cubic foot unit will be up to that task?

    Any opinions appreciated.

    Question

    Our ice box volume is less than yours, altho our Isotherm conversion is working fine.
    Bob M, up in Pt Angeles, is installing a similar model in his E-34.
    I am pretty sure that Bob found the guys @ Sure Marine in Seattle to be as helpful as did I.

    While you might have a dealer closer to your home, it might not hurt to dial them up.
    They were patient and helpful with me before and after the sale.

    I would guess that the sizing of the evaporator plate (or freezer box) is the only "variable" for our small ice boxes, given that there are only one or two compressor sizes.

    My guess is that the beer will be cold with such a unit.

    It's easy in the slip, with nobody opening the top all week and the engine not running hot nearby.

    Ventilate the installation. Cooling the icebox makes hot air, and that hot air needs to evacuate or the thing works against itself.

    I have a big cowl vent on the cockpit coaming right over the compressor.

    I removed a rusted-out non functioning unit when I bought the boat (the boat listing touted "12V refrigeration!"). The compressor was installed starboard and aft of the engine. Actually quite an accessible open area. I think there is a lot of ventilation there, but I can add a flexible duct lead from one of the transom cowls.

    I have the previous model 32 and find that, at least the way I use my boat, that 12V refrigeration is not as helpful as you'd think.

    It uses a lot of energy, ice is required to cool things down quickly initially anyway, and I'm not cruising long enough to push the envelope on cool-vs-cold food.

    Solution: block ice, ice frozen in jugs, and a portable ice maker, $80. Run the ice maker from an inverter at anchor or when on shore power. Once it gets going an ice maker can make quite a bit of ice over the course of a few hours, and it shuts itself off when the water tank is emptied so you aren't likely drain your batteries if you forget about it for a while. If you put the made ice into bags or Tupperware containers, you can run the melt through the ice maker again and refreeze it endlessly.

    When I lived aboard in SoCal I did use the 12V Adler-Barbour reefer constantly, but I was on a dock and had the battery charger on 24/7. This was bad for the batteries and a small 110V fridge would have been better. I have considered cannibalizing a dorm room-style fridge for installation into the icebox, but the AB system has not had the decency to fail since I bought the boat in 1991 and I haven't had the heart or the time to rip out a perfectly good system.

    My electrician says that recharging of batteries at the dock while running a fridge is not harmful to the batteries, but in fact good for them.

    I wonder who's right. Tom?

    Some units can use AC or DC. That better?
