Designing a Refrigerator or Freezer box for your boat starts with calculating your box volume, which we expressed in Cubic Feet (Cu Ft). Once we know the box volume, we can then recommend a Eutectic Plate system sized to match your box volume.
With decades of designing, installing, and troubleshooting refrigerators and freezers on boats, two of the leading causes of a poorly performing system are:

• Undersized Compressor for the box volume.
• Undersized Surface area of the Evaporator.
  Knowing these common problems, part of our system design process is to calculate your box volume and heat load for your Refrigeration Box. This allows us to make sure the system we recommend will be matched to your Box specifics, to meet your expectations of box temp and daily power usage. Additional factors that come into play in designing an energy efficient refrigeration system for your boat are:
• Box Insulation thickness
• Box type (Refrigerator or Freezer or Freezer/Refrigerator Combo Spill-Over Unit)
• Expected cruising ground ambient temperature.
  With these data points, we can calculate the daily heat load (in Watts) for your refrigeration box and know the OzeFridge compressor run time needed to remove that amount of heat per day. Designing a good Refrigeration system isn’t guesswork, it’s Science that follows the time proven laws of thermodynamics.
  Understanding and applying this data doesn’t just make for a more energy efficient marine refrigeration system for your boat, it helps you live up to our Motto, “Go Cruising, Not Camping”.
