Has anyone out there replaced similar? Is there a way to run this unit and keep the amps down by replacement of modern parts?
Its a big consumption
. Advice would be much appreciated.
Old school eutectic plate refrigeration
may not be as outdated as you think on a 43 ft Slocum. In the absents of pictures of your system those who might want to offer advice need more information. Normal refrigeration
running time was 2 to 3 hours a day. Are you saying when unit runs it draws 30 amps continuous for 2 to 3 hours or, as much as 90 amp-hrs in three hours? Thirty amp draw would if this were an AC current
compressor it would be at least a one horse power large compressor. It sounds more like you have a 12 or 24 volt DC ˝ horse power compressor driven direct by a large DC motor
or a belt pulley system. I would caution against thinking a modern compressor or new system being a solution.
You are the best judge of how your system is performing today:
After running 3 hours is the eutectic plate when tapped on solid or a teeny sound.
Is there frost covering complete eutectic plate if not describe where there is lack of frost.
To confirm insulation
is not compromised with age or moisture turn power off to fridge and see how long box temperature will hold in 12 and again in 24 hours.
Most units that draw as much current
as yours will have a liquid sight glass used to determine volume of refrigerant in system look for it and report what you see in the viewing window after compressor has run for at least 30 minutes.
