Knowing the facts and performance of your old system will help establish a base line needed to recommend a replacement unit. Using manufacturer’s charts
of box size, insulation
information and even comparing one boat’s refrigeration
against another like boat
is of little value if current
quantified base line info is available.
Who is manufacture of present refrigeration
Type of refrigeration air or water
Twelve volt or Alternating current
Size of compressor
41 with small 12 volt dual compressors had condensing units under stairs. Where is your compressor
condensing unit or units located?
If your refrigeration is powered electrically list source of energy: alternator
or on board generator
Present systems performance experience that will establish a reasonable base info to develop a new replacement refrigeration unit:
Age of present refrigeration and age of box insulation
Are there any cool spots on box exterior walls or top?
Compressor model number or Btu capacity or normal running amperage?
Approximate hours per day that compressor or compressors run?
What temperatures do you operate boxes at and are you satisfied with temperatures in Freezer
Do the above answers represent summer weather
