Frigoboat – Frigomatic K 50F 12/24V – code: E51975 – Veco

Frigoboat – Frigomatic K 50F 12/24V (E51975) Veco: motor compressor unit with keel cooling

The Frigoboat – Frigomatic K 50F 12/24V (code E51975) supplied by Veco is a motor compressor refrigerator in direct current designed for nautical applications, where reliability, size and ease of installation are central aspects. The system is designed to transform an insulated compartment of the boat in a refrigerator or freezer, depending on the evaporator and the system configuration.

The peculiarity of the version “K” version is the keel cooling (keel cooled): condensation occurs through a through-hull heat exchanger, using seawater in contact with the hull. This design avoids the use of a dedicated water pump and reduces the complexity of the cooling circuit compared to solutions requiring forced circulation.

Main features and details

Power supply and system architecture

• 12/24V DC power supply, suitable for onboard direct current systems.
• Condensing unit for marine refrigeration systems, designed to work with evaporators from the Frigoboat range.
• Keel cooling via through-hull exchanger.

Declared components and equipment

• Secop BD50 compressor.
• System precharged with R134a refrigerant.
• Self-sealing quick couplings to simplify connection and maintenance operations.

Integration with Frigoboat evaporators

The Frigomatic K 50F is designed to be paired with various Frigoboat evaporators, to create a system consistent with the volume and intended use (refrigerator or freezer). Depending on the chosen configuration, it can be used to build refrigerators up to approximately 380 liters or freezers up to approximately 100 liters.

Typical applications in the nautical field

This condensing unit is normally used as a component for:

• Building an onboard refrigeration system in an insulated compartment (fridge or freezer, depending on the evaporator).
• Replacement installing the condensing unit in existing systems when a 12/24V DC setup is desired.
• Installations where a outboard cooling compared to air condenser solutions.

It is often considered in navigation contexts in hot climates, where heat dissipation through the hull can be a technically interesting choice compared to air configurations, especially when aiming to contain the complexity of the system.

Operational advantages (without forcing the data)

Outboard cooling: simplicity and reduction of complexity

The adoption of the through-hull heat exchanger allows to eliminate the need for a dedicated water pump for the condensation circuit. In practice, components are reduced and some system management activities are simplified, an aspect appreciated in maintenance and refitting.

More straightforward installation and maintenance

The presence of self-sealing quick couplings this is a useful detail to make connection operations and technical interventions easier, maintaining an orderly and “system-like” approach typical of the Frigoboat marine range.

Consistency with onboard DC systems

The power supply 12/24V DC makes the Frigomatic K 50F suitable for many marine electrical configurations, where the refrigeration system operates on direct current and must integrate with the onboard distribution.

Usage and notes for selection/replacement

Product identification

• Product: Frigoboat – Frigomatic K 50F 12/24V
• Supplier code: E51975
• Supplier: VECO S.P.A.

For a correct replacement, it is good practice to verify the correspondence of the code E51975 and the type of system (particularly the presence of the outboard cooling), as well as the compatibility of the evaporator already installed or planned.

Installation notes (general indications)

• Provide for an installation consistent with a keel cooled, system, including the through-hull heat exchanger as an integral part of the project.
• During configuration, choose the’Frigoboat evaporator depending on the use (fridge/freezer) and the volume of the compartment.
• For interventions on the refrigeration circuit and refrigerant, rely on qualified personnel and follow the procedures provided by the system.

If you are performing a refitting or replacement, and have doubts about the existing configuration (evaporator, connections, pass-through arrangement), it is advisable to collect photos and data of the current system before ordering, to reduce the risk of incompatibility.

FAQ – Frequently Asked Questions

What is the Frigoboat Frigomatic K 50F (E51975)?

It is a Frigoboat motor compressor refrigerator powered at 12/24V DC, supplied by Veco with code E51975, designed for nautical refrigeration systems on insulated compartments (fridge or freezer depending on the configuration).

What does keel cooled mean?
