    User manual iSave 21 3. Safety 3.1 General The iSave must not be used for other purposes than those recommended and specified without first consulting your local iSave distributor. This manual must be read and completely understood by the responsible specialist person- nel prior to installation and commissioning.

  • Page 9: Intended Use

    User manual iSave 21 3.2 Intended use The iSave is designed for use as energy recovery device in Sea Water Reverse Osmosis (SWRO) or Brackish Water Reverse Osmosis (BWRO) system. The iSave must not be used for other purposes than recommended and quoted for without consulting your local iSave distributor.

  • Page 10: Preferred System Design

    21 3.4 Preferred system design Danfoss recommends building systems with a high degree of safety. The PI&D in chapter 5.16 shows the Danfoss preferred system design. • It is always the system builders’ responsibility that the system design does not cause any form of hazard and are adapted to local regulations.

  • Page 11: Centre Of Mass

    User manual iSave 21 Check the mass (weight) of the iSave unit. All parts weighing more than 20 kg must be lifted using lifting slings and suitable lifting devices, e.g. an overhead crane or industrial truck. All iSave units weight more than 20 kg.

  • Page 12: Storage

    Storage temperature: 1°C to +70°C (33°F to 158°F) – provided that the pump is drained of fluid and stored “plugged”. Frost protection is required at temperatures below 1°C. Danfoss recommends using DOW- FROST from DOW Chemical Company or Chillsafe mono propylene glycol from Arco Chemi- cal Company.

  • Page 13: Technical Data And Design Review

    The noise level from the iSave including the electrical motor is 86 dB (A). Measurements ac- cording to EN ISO 20361. The test is made under following conditions: 1. iSave and electrical motor mounted on Danfoss base plate. 2. Baseplate is isolated from concrete ground by rubber vibration dampers.

  • Page 14: Materials

    User manual iSave 21 5.3 Materials All critical parts of the iSave are made of super-duplex 1.4410/UN S32750 or the like. Non-critical parts that are not in contact with sea water are made of AISI316. The shaft to the electrical motor is sealed by a standardised mechanical seal.

  • Page 15: How Does The Isave Work

    User manual iSave 21 5.7 How does the iSave work? Figure 5.1 shows a section view of the iSave The iSave consists of a rotating isobaric pressure exchanger and a positive displacement pump, also called booster pump. The rotation speed of the pressure exchanger and the pump is exactly the same, as they are driven by the same electric motor.

  • Page 16: Booster Pump

    User manual iSave 21 5.7.2 Booster pump The booster pump is a positive displacement pump, which means that the flow is controlled by the speed of the electric motor; e.g. if the rotation speed of the electric motor is raised by 10%, the flow will be 10% higher and vice versa.

  • Page 17: Seawater Quality

    The iSave may request a different pre-filter of the seawater than the HP pump and other components in the RO system. As the various filters on the market differ greatly, Danfoss RO Solutions recommends us- ing cartridges with consistent, reliable performance and high efficiency, in which fibres are blown continuously onto a central support core.

  • Page 18: Air Bubbles

    User manual iSave 21 For more information on the importance of proper filtration, please consult our publication “Filtration”, which also will provide you with an explanation of filtration definitions and guid- ance on how to select the right filter. See section 5.8.1 for filter installation instructions.

  • Page 19: Flushing

    User manual iSave 21 5.11 Flushing RO membranes require periodic flushing to limit biological fouling. There are two types of flushing: feed water (Seawater) flush and fresh water (Permeate) flush. Regardless of the flush water used, the water must be pre-filtered to the level described in chapter 5.8.

    User manual iSave 21 5.14 Over-pressurisation caused by low pressure isolation If the low-pressure side of the iSave is blocked and the iSave is exposed to high-pressure, there is a risk that the iSave or the LP piping could be damaged by over-pressurisation.

  • Page 22: On-Site Installation

    Danfoss provides the iSave with a baseplate and support brackets. Although the baseplate is of a sturdy design, it can flex or bend when it is bolted to the foundation. The baseplate thus requires a solid foundation such as concrete or rigid steel frame.

  • Page 23: Piping And Joints

    User manual iSave 21 6.4 Piping and joints Piping material and schedule is of high importance. The strength of the Victaulic® connec- tions is influenced by the material used for both the Victaulic® clamps and the hard piping. The hard piping and connections used must be of proper design and must be installed in accordance with the manufacturer’s recommendations.

    User manual iSave 21 6.5 Flexible couplings and flexible hoses. The strength of the Victaulic® connections is influenced by the material used for both the Victaulic® clamps and hose couplings. The flexible hose and connections used must be of proper design and must be installed in accordance with the manufacturer’s recommendations.

  • Page 25: Accessibility

    User manual iSave 21 6.8 Accessibility With respect to the service and replacement of the complete iSave unit, it is recommended to maintain sufficient space around the unit. The space must be sufficient enough to allow for safe lifting of the equipment, with no risk for personal injury and/or damage to the iSave.
