Consistency with Gianneschi spare parts

This item falls under the spare parts Gianneschi and is offered with clear references (model and code) to facilitate the identification of the correct component. When replacing, it is good practice to check:

• the match of the code 21ALT020N with the spare parts list or system documentation;
• the compatibility of the’1/2″ male connection with the existing fittings;
• the available space and mounting orientation, based on the circuit configuration.

Typical applications (nautical and plant engineering)

The water vessel is a component commonly used in systems where it is useful to manage pressure and circuit behavior more regularly. In nautical and technical fields, it can be used, for example, in:

• pressure tanks and water pressurization systems;
• onboard water systems with intermittent users (taps, showers, toilets);
• circuits where a more stable response to demand variations is desired.

Actual applications depend on the system configuration and the specifications of the system in which the component is installed. For special installations or complex systems, it is advisable to refer to the manufacturer's technical documentation or your trusted maintenance technician.

Operational advantages

Without entering into undeclared performance, a correctly sized and installed expansion tank can offer practical benefits in the daily use of the system:

• Greater circuit regularity: helps manage the typical demand variations of water users.
• Support for pressure stabilization: helps make the system's behavior more uniform during usage cycles.
• Identifiable spare part: the presence of code and model facilitates replacement and maintenance management.
• Practical format: 2 L capacity suitable for installations where space and ease of integration are important (depending on the system layout).

Use, installation, and maintenance notes

General replacement instructions

Replacing an expansion tank requires attention to safety and proper circuit management. In general:

• secure the system and release the pressure before intervening;
• check that the’1/2″ M connection is consistent with the fittings and the intended orientation;
• check the condition of pipes and fittings, replacing any worn components if necessary;
• at the end, restore the system and check for leaks.

To avoid installation errors or interventions not compliant with the manufacturer's procedures, it is advisable to rely on qualified personnel, especially in the nautical field.

Useful notes for identifying the replacement part

To correctly order or compare the component, use the references:

• Gianneschi – Expansion tank BFIWH
• Code: 21ALT020N
• Brief descriptionWater tank 2 L, 1/2″ M connection, FL/Stainless steel

If you are replacing an existing component and have doubts about compatibility, always compare the code and connection with what is shown on the installed spare part or the system documentation.
