Hydrophore System / PackageOffshore/Products

A hydrophore system consists of a set of pumps, connected to a tank, mounted on a skid frame with control panel. Pumps draw fluid typically from a sealed tank located elsewhere, which is then pumped to pressurise a bladder within a tank adjacent on the skid.

A hydrophore pressure tank is used which is partially filled with water and above that compressed air is provided for head pressure. Compressed air builds head pressure, so that water can reach up to highest level and remote places.

Mowe’s has the ability in providing Hydrophore System / Packages Hydrophore tanks for Fresh Water, Sanitary Water and Potable Water Systems according to customer’s specifications and potable water approved standards.

Hydrophore system package

Hydrophore system consists of :

(Air compressor can be of Oil Free/ Clean Water compressors)

A hydrophore pressure tank is to store fresh water and monitors and maintains the water pressure in the tank in order to sustain a 24-hours operational supply of fresh water at constant water pressure in the pipelines to multiple location in the vessel and at any desired height of the ship or building.



There are two Hydrophore systems used globally.

1.   Fresh Water Hydrophore System - are typically used for human consumption, as drinking water after treatment, gally use like sinks, laundry and showers. Fresh Water Hydrophore System is connected with Fresh water generator (FWG), with salinometer & ppm controller. There is a dump valve through which controlled fresh water is passed to Water storage tank and then to Hydrophore Pressure Tank.

This type of package involves equipment like:

- UV Sterilisers

- Activated Carbon Filters

- Chlorination of water

- Anodizing of water

- Alkaline electrolysis of water

Depending on the demand of the potable water, various treatments are in place to produce the needed water.

Such potable water systems usually have a higher control over the flow rate of water as water needs to be treated in a controlled environment.

2.   Sea Water Hydrophore System – used for sanitary application, deck wash, equipment wash and even fire fighting / fire sprinkler systems.

As sea water is highly corrosive, there the equipment used in such systems needs to be suitable. This include material like bronze, SS316 (which may not be the best) and other material that is applicable / resistive to sea water.

A filtration system needs to be in place to avoid sea water contaminants from damaging key equipment.

It is also common to see such systems with higher pressure and higher flow than fresh water hydrophore packages.
