Fresh water pressure tanks are essential devices for ensuring constant and stable pressure in boats' plumbing systems, especially for drinking water. These systems are particularly useful for supplying faucets, showers, sinks, and other onboard appliances where adequate pressure, similar to that of a household, must be maintained.

Types of Autoclaves for Clear Water

Membrane Autoclaves

• The most common type on boats. They use a rubber membrane that separates the water from the air pressure.
• They offer optimal pressure management, avoiding peaks and fluctuations.

Autoclaves with Pressure Switch

• They turn on and off automatically based on water pressure.
• They can also be used in systems with storage tanks.

Silent Autoclaves

• Designed to minimize noise during operation.
• Ideal for boats where acoustic comfort is a priority.

Features to Consider

✔ Working Pressure – Choose a model that supports the pressure required for your system. Typically, a pressure of 2-3 bar is sufficient for most boats.

✔ Flow Rate – Measured in litres per minute (L/min), depends on your water needs on board.

✔ Power – Most marine water pumps are powered by 12V or 24V , so make sure it is compatible with your electrical system.

✔ Overload Protection – Some models include protection devices against overheating or dry running.

✔ Quiet – If you want to minimize noise, opt for models with silent technology.
