Sea Frost vs. Vitrifrigo: Which Type of Marine Refrigeration Do You Need?
Shopping for marine refrigeration can feel confusing, especially if you are not sure whether you need a complete refrigerator or a system to cool an existing icebox. At Marea Marine, we help boat owners with this question often.
The easiest way to understand the difference is this: Sea Frost makes refrigeration systems for custom boat iceboxes, freezer boxes, bait freezers, and other built-in cooling projects. Vitrifrigo makes complete, ready-to-install marine refrigerators, freezers, and drawer units for boat galleys and cabins.
Below, we will walk through the difference in plain language so you can better understand what may work for your boat.
The Quick Answer
| If you need… | A Sea Frost system may be right for you | A Vitrifrigo refrigerator may be right for you |
|---|---|---|
| A way to cool an existing insulated icebox | Yes | Usually no |
| A custom refrigerator or freezer built into your boat | Yes | Sometimes, depending on the space |
| A complete refrigerator with a finished door, shelves, and cabinet | No | Yes |
| A replacement for an old built-in boat fridge | Possibly, if it was a custom box system | Yes, if you are replacing a finished refrigerator appliance |
| A bait freezer or fish-box cooling setup | Yes | Usually no |
| A drawer-style refrigerator or fridge/freezer for your galley | No | Yes |
| A water-cooled refrigeration setup | Yes | Usually no |

What Is Sea Frost?
Sea Frost is a marine refrigeration brand that makes the equipment needed to cool a custom insulated box on a boat.
In other words, Sea Frost is usually not the finished refrigerator cabinet that you see in a boat galley. It is the cooling system that goes behind the scenes to turn an icebox, freezer box, fish box, or bait box into a working refrigerator or freezer.
For example, many boats have an insulated cooler box already built into the galley, cockpit, or fishing area. It may have a lid, but no working refrigerator system. A Sea Frost system can be installed with that box to keep food, drinks, bait, or fish cold.
Marea Marine currently carries several Sea Frost refrigeration options, including the BD Air-Cooled System, BDXP Air-Cooled System, Baitfreezer Air-Cooled System, and BG Water-Cooled Condensing Unit.
What Is a Vitrifrigo Refrigerator?
Vitrifrigo is a brand that makes complete marine refrigerators and freezers. These are finished appliances that are ready to install into a boat’s galley, cabin, or cabinet opening.
A complete Vitrifrigo unit already has the refrigerator box, door or drawer, shelves, and cooling system built together. This is usually what boat owners need when they are replacing an older built-in refrigerator or remodeling a galley.
For example, if you currently have a front-opening refrigerator in your boat and want to replace it with a newer unit that fits into the same cabinet area, you would likely start with the Marea Marine refrigerator collection.
Marea Marine’s collection includes 34 complete Vitrifrigo refrigerator and freezer models, including front-opening refrigerators, drawer refrigerators, refrigerator/freezer combinations, and double-compartment drawer units.
Think of It This Way
| Your boat has… | You may need… | Start here |
|---|---|---|
| An insulated icebox that is not refrigerated | A Sea Frost cooling system to turn the box into a refrigerator or freezer | Sea Frost systems |
| A built-in refrigerator that has stopped working | A complete replacement refrigerator, if the old unit is a finished appliance | Complete marine refrigerators |
| A custom fish box or bait box | A refrigeration system designed for that specific box and use | Sea Frost systems |
| A galley cabinet opening for a refrigerator | A finished, ready-to-install marine refrigerator | Complete marine refrigerators |
| A need for a drawer refrigerator | A Vitrifrigo drawer refrigerator or fridge/freezer unit | Complete marine refrigerators |
| A need for seawater cooling or a separate condensing unit | A Sea Frost water-cooled refrigeration system | Sea Frost systems |
Sea Frost: Best for Custom Cooling Projects
A Sea Frost system may be a good fit if your boat has a custom box that needs to be cooled. This could be an old icebox in the galley, a built-in freezer box, a fish box, or a bait freezer.
Sea Frost systems allow you to choose a setup based on your boat’s space, voltage, cooling needs, and the type of box you want to cool.
Sea Frost models available at Marea Marine
| Sea Frost product | What it is | May be a good fit for |
|---|---|---|
| BD Air-Cooled System | A 12V or 24V DC refrigeration system with an air-cooled condensing unit | A well-insulated boat icebox or custom refrigerator box |
| BDXP Air-Cooled System | A higher-capacity air-cooled refrigeration system | Larger refrigerator or freezer boxes |
| Baitfreezer Air-Cooled System | An AC-powered freezer system available in 110V or 220V options | Sportfishing boats that need a dedicated bait freezer |
| BG Water-Cooled Condensing Unit | A water-cooled refrigeration option |
Specialized applications where seawater cooling is a better fit |
The Sea Frost BD Air-Cooled System is designed for well-insulated refrigerator boxes and runs on 12V or 24V DC power. It uses a separate compressor and cold plate, which are installed with the boat’s existing insulated box.
The BDXP system has more cooling capacity than the standard BD system and may be a better choice for a larger refrigerator or freezer project.
A simple Sea Frost example
Let’s say your boat has a large insulated box under the galley counter. Right now, you fill it with ice every time you go out. You want to stop buying ice and use the box as a refrigerator instead.
Because you already have the insulated box, you may not need a complete refrigerator cabinet. You may need a Sea Frost system that can cool the box you already have.
Before choosing a system, we would want to know:
-
The inside measurements of the box
-
Whether you want a refrigerator, freezer, or both
-
How thick and effective the insulation is
-
Whether your boat uses 12V or 24V DC power
-
Where the compressor can be installed
-
Whether the area has good airflow
-
How you use the boat: day trips, fishing, weekends, or longer cruises
Vitrifrigo: Best for Complete Replacement Refrigerators
A Vitrifrigo refrigerator may be a better fit if you need a finished appliance that slides into a cabinet opening or mounts in your boat’s galley.
These models are good for boat owners who want a complete refrigerator, freezer, drawer refrigerator, or refrigerator/freezer combination without building a custom insulated box.

A simple Vitrifrigo example
Let’s say you have an older refrigerator in your boat galley. It already has a finished door, shelves, and its own cabinet. The unit no longer works, and you want to replace it with a newer one.
In that case, you would likely measure the cabinet opening, depth, and available ventilation space, then look for a complete Vitrifrigo refrigerator that fits.
Main Differences at a Glance
| Question | Sea Frost | Vitrifrigo |
|---|---|---|
| Is it a complete refrigerator cabinet? | No. It is usually a refrigeration system for a custom box | Yes. It is a complete refrigerator, freezer, drawer, or fridge/freezer appliance |
| Is it made for an existing icebox? | Yes | Usually no |
| Does it include a finished door or drawer? | No. The boat’s existing box or custom build provides that | Yes |
| Can it work for a custom freezer or bait freezer? | Yes | Some refrigerator/freezer units may work for standard food storage, but Sea Frost is the better place to start for custom box projects |
| Does it require planning for a compressor and cooling components? | Yes | The cooling system is built into the appliance, but you still need proper fit, ventilation, and power |
| Is it a good option for a galley replacement? | Only if the galley uses a custom icebox or box-based system | Yes, in many cases |
| Can it be water-cooled? | Yes, depending on the Sea Frost system | Usually not the main option for this type of appliance |
| Who should consider it? | Owners building, upgrading, or repairing a custom refrigerator or freezer box | Owners replacing or adding a finished refrigerator or drawer unit |
How Do I Know Which One I Need?
The best first question is: Do you already have a finished refrigerator, or do you have an insulated box?
If you have a finished refrigerator with a door, shelves, drawers, and a complete cabinet, start by looking at complete marine refrigerators from Vitrifrigo.
If you have an insulated icebox, freezer box, fish box, or bait box that needs a cooling system, start by looking at Sea Frost marine refrigeration systems.
If you are still unsure, that is completely normal. Marine refrigeration systems need to match the boat, the available space, the power setup, and how you use the boat.
