Our beloved Glacier Bay system finally gave up the ghost a couple of months ago, and we wound up replacing the system with 2 independent Sea Frost bdxp evaporator systems.
I am not happy about it, at least on the freezer
side. The fridge is fine. Here's why.
First, while the GB unit happily held the temperature down in the single
digits, the SF unit struggles to maintain 20 degrees at the top of the box. Down at the bottom, it's about 12. We're in Ireland
now, so it's better, but in Charleston in July, the damn thing ran around the clock. Even here in Ireland
, It won't achieve single
digits. We added the water cooling
option, so it's not an issue with temps at the units.
A call to SF revealed that they view anything under 28 degrees as an acceptable temperature for a freezer
. This is a new one on me. I can tell you that the ice cream doesn't do well in the 20's.
Here's my real problem, however. The SF uses a LOT more energy in real life than the GB did, even with the box 10-15 degrees warmer than before. I'm sure that the SF uses less AH per day than the GB did, but EFFECTIVELY
, it uses far more power.
The reason is that the GB would cool like hell while running the engine
to charge the batteries, bringing the box temperature down into the negatives. Our big alternator
would happily supply the extra amperage while giving the batteries all they wanted. After we would shut down, the freezer side of the GB would pretty much not run all day.
The SF, on the other hand, runs incessantly. It doesn't have a 'high gear' to drop the temp while charging
, so it's pretty much just running all the time.
We have no insulation
issues, as the boxes are unchanged from what they were with the GB. With the system being new, I can't imagine we have a charge issue. There are 2 plates, occupying 2 full sides of a 6CF box.
I've been pretty horrified by how fast my batteries have been depleting with this new setup.
Any suggestions? Rip out the SF freezer and put a holding plate setup in? I just spent a heap of money
on this thing, so starting over is a poor option for sure.
Hopefully, somebody has some insights on this one, other than telling me that I bought a lousy system...
