Yes I actually remember reading this thread on his forum I'm glad to hear you got it all working. I'm actually replacing a pretty nice semi-working unit with a stainless evaporator, but I don't really have the time I need to do all this soldering, testing, evacuating, recharging etc and I need a DC unit.
I will check into the sea frost bd80 system. Lee, there is an adhesive foam insulation tape used for insulating refrigerant lines. It is about 7 dollars for a 30' roll at home depot in the HVAC department. You should wrap your expansion valve with that tape and that will stop your sweating problem. You can cut the foam to whatever shapes you need to wrap the valve and totally seal and insulate it. I have used it on the refrigerant lines for my Cruisair A/C units (I have split systems) and it has eliminated sweating. The lines used to sweat through the old insulation so I wrapped another layer and it stopped. -Merrill -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lee Haefele Sent: Wednesday, November 21, 2007 3:21 AM To: [email protected] Subject: Re: [Liveaboard] refrigeration Last year Sea Frost offered me a system, with the BD80. I was having trouble finding a new electronic control unit for the BD3f compressor, but eventually found one. Sea Frost normally ships pre charged with R-134 and special disconnects, but my system was installed at boat build with plain connectors. My system is set up with automobile A/C style test fittings and a sight glass on the receiver/dryer. I bought a $29 set of Harbor Freight gauges and can add R-134 from the 12 ounce cans available at Wal-Mart. The boat came to me used from Moorings Charters with the fridge barely working. Sea Frost and Kollmann talked me through the evacuation, recharge and adjustment. One complaint: I cannot get the expansion valve totally insulated/sealed from air. It sweats and drips water, it should be mounted inside the fridge instead of outside.
