Fresh water generation

HEM® RO Simplex desalinator, series 20-80

HEM® Series 20 system is designed for small yachts where space is very limited. The system is available as a monobloc unit enclosed in an aluminium frame. This is compact without being inaccessible for routine service, and allows for fast, simple installation. It can also be supplied in modular form, as seven smaller modules with a completely preplumbed and electrically preconnected main panel for flexible installation.

HEM® Series 25 system is designed for medium sized yachts where a heavy duty unit is required, but one which is compact. Over the years, these units have supplied millions of tons of water for yachts all over the world. The system is available in modular or frame configurations to suit the available space.

HEM® Series 30 was designed to fit the gap between the Series 25 and 40 units, where a higher production than the series 25 is required, but space for the Series 40 is not available.

The HEM® Series 30 uses the 4 inch membrane which gives flows of 375/541/625 litres/hour for the three different models. The framed unit is very compact, whilst still providing unusually good access to all system parts for servicing.

The modular unit does not take up much more space than the Series 25, but gives up to three times the output. A sand filter is strongly recommended if space is available, as the system has a high feedwater flow.

HEM® Series 38 system is designed for refit applications and vessels with minimal space. Despite the compact design, it still provides excellent access to all system parts for servicing.

HEM® Series 60-80 is designed to produce large volumes of water for superyachts and commercial vessels, the HEM® reverse osmosis desalinators, series 60-80 combine a low space requirement with good accessibility for servicing.

Where the system is used for land based water supply, it is often installed in a refurbished 20 or 40ft container which enables the unit to be safely transported and housed on site.

Several variations of design are available depending on the working conditions and intended purpose for the product water. Any standard system can be adapted to your exact requirements.
