Frigomatic 12-24V refrigeration systems

Built to the highest specification and designed for self-installation, Frigomatic refrigeration systems deliver the best performance. 12V or 24V DC fridge or freezer units, with the lowest power consumption, whether air cooled, keel cooled or pump water cooled.

Frigomatic includes a wide range of evaporator plates, either air cooled, keel cooled or pump water cooled. These condensing units help optimize your fridge or freezer system in an existing insulated cool box.

Easy to install, with all components pre-charged with R134a refrigerant and connected by the unique Frigoboat’s re-sealing ‘quick couplings’ system and controlled with either mechanical or digital thermostats.

How do I choose my Frigomatic system?

1) Calculate the volume of the fridge/freezer

In order to choose the right size condensing unit set and evaporator, we need to calcuate the volume:

2) Choose the evaporator that best suits your box

Evaporators are available in different shapes; choose the right one based on the shape of the unit,  and if you need a fridge or freezer.

3) Select the most suitable condensing unit

Air cooled, water cooled, or keel cooled?

It depends from installation constraints, how much efficiency you want from the system, and from navigation conditions. See details in Condensing Unit section.


4) Select the thermostat that best fits your system

Fridge or freezer, digital or mechanical, Frigoboat offers a wide range of thermostats, for every possible need.

Frigomatic thermostats

Frigoboat Mechanical thermostat

Simple and easy, our Frigoboat mechanical control has been designed to keep the fridge/freezer temperature always under control. This thermostat can be installed inside the refrigerated compartment.

Digital thermostat

To have a better monitoring of the cellar temperature, Frigoboat offers a digital display.

Frigomatic condensing units

Air cooled Frigomatic

Frigoboat offers a wide range of air cooled Frigomatic systems, for every type of installation. An air-cooled system is less efficient than a water cooled system but is cheaper and easier to install. To achieve maximum energy efficiency, the air is conveyed to an aluminum fin condenser.

Choose air cooled for Northern European cruising.

Keel cooled Frigomatic

A water-cooled system is more efficient than an air cooled one because water dissipates heat far better than air. Moreover, keel cooling is also more efficient, reliable and quieter than a pump water cooled system as the only moving part required is the compressor.

Choose a water cool if you are planning to cruise the Mediterranean or Tropics.

Water cooled Frigomatic

A water-cooled system is more efficient than an air cooled one because water dissipates heat far better than air.  Water cooled Frigomatics require a pump to bring water to the heat exchanger, designed for the best efficiency and resistance, thanks to the marine grade copper-nickel.

Choose a water cool if you are planning to cruise the Mediterranean or Tropics.

Frigomatic evaporators

Supplied with a 2,8 mt copper pipe, pre charged with refrigerant, as standard; pre-charged pipe extensions are also available from 1 to 6 meters.

All Frigomatic evaporators come with Frigoboat self-sealing couplings.

Available in 3 different models, each with a wide range of different sizes, Frigomatic evaporators can satisfy any installation requirement.

F Serie

Flat evaporators are ideal for fitting into cold boxes that will become a dedicated refrigerator or freezer unit, as they maximize both the access and the volume available. They can be bent (to a 25mm radius) to fit around the inside of the box.

F-Inox Serie

F-Inox Flat evaporators, like F Series, are built within a stainless steel cover, to further protect them.

B Serie

All Frigomatic B series evaporators can be used as a freezer compartment within a fridge or as a dedicated freezer. These freezer compartments can be mounted vertically or horizontally. The 340B has an optional lid, when used horizontally.

H Serie

All Frigomatic H series evaporators can be used as a freezer compartment within a fridge. These freezer compartments can be mounted vertically or horizontally.

Frigoboat keel coolers

The Frigoboat keel cooler takes the water from the outside of the hull in order to cool and condense the refrigerant in the system.

Produced in marine bronze, the sintered plate protects the heat exchanger from damage; while offering the best efficiency in terms of heat exchanging capabilities.

The internal heat exchanger, in marine cupro-nickel, maximizes resistance to corrosion. Similar to a sea water intake, the frigomatic outhull, through the hull, has a diameter of 38 mm and is fixed using a threaded nut.

Keel coolers are available in 2 versions, one with short thread and one with a longer thread; both models can be ordered with or without sacrificial zincs to further protect the system from galvanic corrosion.

With or without zincs?

Both keel cooler models are available with or without sacrificial zincs. Zincs are installed on the keel cooler itself, close to the surface.

Zincs are only needed if the keel cooler is not already electrically connected to the vessel’s sacrificial zinc.


Frigomatic speed regulator

Placed on the compressor controller, the Speed Regulator is a manual speed adjustment device (standard on most Frigomatic units).

Frigomatic extension pipes

A full range of extension pipes, fitted with Frigoboat self-sealing couplings, allows installation of your Frigomatic condensing unit up to 6 meters away from the evaporator.

Frigomatic sea water pump and strainer

Self-priming pumps are specifically designed for Frigomatic water cooled refrigeration systems. Minimum amperage draw (less than 1A in 12V) and rated for continuous operation, it can pump water up to 2 mt and it is particularly quiet.

Self priming pumps can be used to cool up to 3 Frigomatic condensing unit by adding a pump interface or a pump relay.

Pumps need a sea water strainer; Frigoboat ones come with a stainless steel support.

Frigomatic pump interface

Our Frigoboat pump interface is a very useful accessory when it comes to connecting several Frigomatic units to the same cooling pump.

Frigomatic voltage divider

A Voltage divider (24V/12V) is used to run Frigomatic units on a 24V power supply; the maximum power draw of this device is 3A.

230V AC controller option

An optional electronic controller, is built to work on a 230V/50-60 and 115V/50-60 power supply; the controller can automatically switch from one power supply to another. Eg. when the main supply is available, the device will automatically run on it, bypassing the battery supply.

Compatible for 12V and 24V installations, it also includes an overload protection for the A.C. supply with a limit of 100W.
