Anodo di sacrificio 3/4" – codice: crcz912 – Frigomar

Anodo di sacrificio Frigomar 3/4″ (codice CRCZ912)

The’anodo di sacrificio 3/4″ Frigomar, Osculati code CRCZ912 (Art. 912), is a spare part dedicated to seawater circuits and heat exchangers used on Frigomar chillers/cooling circuits. It is a threaded sacrificial anode designed to work as a “consumable” element within the system, with the aim of contributing to the protection of metal parts exposed to the marine environment.

Component features and details

This spare part is supplied by Frigomar and is uniquely identified by the product code CRCZ912. The configuration is typical of anodes for seawater systems: 3/4″ threading and body in zinc 99%.

Technical data confirmed

• Manufacturer: Frigomar
• Code: CRCZ912 (Art. 912)
• Type: threaded sacrificial anode
• , a material commonly used in fittings and small parts for systems. The choice of brass is often linked to the need to use components compatible with other elements of the same material and with typical hydraulic configurations. 3/4″
• Material: zinc 99%

Function of the sacrificial anode in the seawater circuit

The sacrificial anode is designed to:

• help protect the galvanic corrosion metal parts of the cooling circuit;
• help preserve the heat exchanger and other components in contact with seawater;
• progressively consume itself instead of the metal components of the system, making necessary a periodic replacement based on usage conditions and environment.

In practice, the anode is a maintenance element: when it is consumed, replacement allows restoring the protection provided by the manufacturer for the circuit.

Applications and compatibility

The official Frigomar spare parts catalog identifies the anode Art. 912 (code CRCZ912) as compatible with the following units:

• HP 0.75
• HP 1.2
• HP 1.5
• HP 2
• HP 2.5

For the indicated models, a attacco filettato da 3/4″. is provided. If you are performing a replacement, it is good practice to always check the spare part code and the thread present on the installed component or on the unit's documentation.

Advantages for maintenance and spare parts management

In a professional context (nautical and onboard plant engineering), using a spare part identified by the correct code simplifies maintenance and reduces the risk of errors during procurement. This Frigomar anode offers practical advantages mainly related to identification and installation:

• Coded spare part: the reference CRCZ912 helps to quickly order the correct component.
• Formato filettato 3/4″: typical solution for installation/replacement on seats prepared by the manufacturer.
• Material in zinc 99%: useful indication to maintain consistency with the configuration provided for the cathodic protection of the circuit.
• Programmable maintenance: being a consumable component, it allows periodic checks and planned replacements based on operating conditions.

Usage, controls and operational notes

The sacrificial anode works continuously during the operation of the seawater circuit. For this reason, it is advisable to include it in the routine plant checks, especially in case of intensive use or in particularly aggressive environments.

General indications

• Visual inspection: during circuit maintenance, check the consumption status of the anode and the integrity of the threading.
• Replacement: if the anode is significantly worn, replace it with the correct spare part (CRCZ912).
• Check seat and seal: during reassembly, make sure the seat is clean and that the threaded coupling is correct, according to the procedures provided for the unit.
• Spare part/model consistency: in case of doubts about compatibility, refer to the Frigomar spare parts catalog or the code present on the installed anode.

Important note

The information provided is based on the data available for the spare part Frigomar CRCZ912 (threaded sacrificial anode 3/4″ in zinc 99%) and on the compatibilities indicated for the listed units. For different applications or non-standard configurations, it is advisable to verify the spare part code required by the plant.
