Frigomatic Threaded Outboard – zinc-free – code: E50361 – Frigoboat

Frigomatic keel cooler with thread (without zincs) – original spare part code E50361

The Frigomatic keel cooler with thread (code E50361) supplied by VECO S.P.A. is a component for onboard systems used in marine refrigeration systems Frigomatic. It is a through-hull heat exchanger (keel cooler), designed to work with seawater in contact with the hull and support the condensation of the refrigerant in the refrigeration circuit.

This version is recommended when you want a replacement consistent with the original system setup and when the installation requires a threaded fastening with tightening by nut. The model is supplied without sacrificial zinc anodes, as per product configuration.

Features and construction details

The outboard E50361 is designed for a through-hull installation and typical use in the nautical field, where corrosion resistance and material reliability are key aspects.

Type and function

• Through-hull heat exchanger (keel cooler) for Frigomatic marine refrigeration systems.
• Uses seawater in contact with the hull to support the condensation of the refrigerant in the refrigeration circuit.
• Solution oriented to a system that does not require a dedicated cooling pump for the condenser, according to the typical keel cooler setup.

Installation: through-hull threaded

• Threaded fastening (through-hull) with tightening nut.
• Short thread (45 mm), suitable for hulls with thickness up to about 40 mm.

Materials

• Body in marine bronze.
• Internal exchanger in cupro-nickel.

Version without sacrificial anodes

• Configuration without sacrificial zinc anodes.

Typical onboard applications

The Frigomatic E50361 through-hull is used as part of the marine refrigeration system, especially when the system is configured with a through-hull heat exchanger. It is a replacement part recommended both during maintenance and in case of replacement of the existing component.

When to use

• For to condense the refrigerant by exploiting seawater in contact with the hull.
• For to replace the original through-hull in case of wear, damage, or need to restore the system.
• To keep the system consistent with systems Frigomatic that use this type of heat exchanger.

Operational advantages (depending on the keel cooler configuration)

In a system with a through-hull heat exchanger, the operating principle is based on heat exchange with external water. This approach is often chosen in the marine field for its installation simplicity and for reducing components dedicated to condenser cooling.

• Essential system setup: using seawater in contact with the hull can reduce the need for additional components dedicated to condenser cooling.
• Quiet operation: the absence of a cooling pump dedicated to the condenser (in configurations that eliminate it) can contribute to quieter operation compared to solutions that include it.
• Original spare part: useful for maintenance interventions aimed at preserving the Frigomatic system architecture.
• Materials for marine use: marine bronze and cupro-nickel are materials commonly used in marine environments for their corrosion resistance.

Usage, notes, and replacement instructions

Being a through-hull component, selection and installation require attention and consistency with the existing system. In particular, it is important to verify that the thread configuration and hull thickness are compatible with the short thread version provided by this model.

Recommended checks before purchase

• Check that the requested replacement corresponds to the code E50361.
• Verify that the intended installation is through-hull threaded with tightening nut.
• Consider the hull thickness in relation to the short thread (45 mm) indicated for hulls up to about 40 mm.
• Keep in mind that this is the version without zincs (without sacrificial anodes).

Operational notes

• For interventions on components passing through the hull, it is advisable to rely on qualified personnel, in line with nautical maintenance practices.
• When replacing, maintain consistency with the Frigomatic system configuration and with the materials/connections already on board.
