HP Desalinator: SCA 220-2 LT/H - with RP TRONIC (automatic pressure regulator) – code: HP SCA 220-2 – HP Watermakers

HP SCA 220-2 LT/H desalinator with RP TRONIC (automatic pressure regulator)

The HP SCA 220-2 desalinator is a solution from the SCA series designed for applications where operational continuity, orderly system management, and automated pressure control are required. This version is configured with RP TRONIC, which integrates the automatic pressure regulation system and a remote control panel, for more practical operation in technical installations (for example in nautical and onboard plant environments).

RP TRONIC: automatic pressure regulation and remote control

• Automatic pressure regulator (RP TRONIC): allows automatic pressure regulation, simplifying the operational management of the system.
• Remote control panel included in the RP TRONIC version, useful for installations where the control point does not coincide with the technical area of the unit.

Membranes and configurability of the SCA series

The SCA series can be equipped with osmotic membranes up to a production of 440 Lt/h with four 31540 membranes (data refers to the series, according to what is reported). The specific configuration of this model is indicated as SCA 220-2.

Feed pump

The feed pump is supplied always separately. This aspect is important during installation planning, as it allows more flexible management of layout, accessibility, and hydraulic/electrical connections.

Available power supplies

The system can be supplied with the following power supplies:

• 110VAC 60Hz
• 230VAC 50Hz
• 230VAC 60Hz
• 380VAC 50Hz
• 440VAC 60Hz

The choice of power supply must be defined based on availability on board/system and the planned electrical integration logic.

Communication and integration (MODBUS)

The standard MODBUS protocol is installed on all units and is indicated as compatible with BiBi and Part-NET Interface. This makes the unit suitable for contexts where it is useful to centralize supervision or integrate the desalination unit into existing control systems.

Reported technical data

• Flow rate: 220 Lt/h
• Nominal flow rate: 300 Lt/h
• Daily flow rate: 5280 Lt/day
• Nominal daily flow: 7200 Lt/day
• Installed power: 2.2 kW
• Total weight: 80
• Dimensions: 842X420X456

Typical applications

The desalinator HP SCA 220-2 with RP TRONIC is suitable for installations where fresh water production by reverse osmosis is an integral part of onboard management or a technical system. In particular, the presence of automatic pressure regulation and remote panel makes it interesting when:

• you want a more orderly control of the unit, with simplified operational management;
• it is useful to command and monitor the system from a location different from the technical room;
• it is expected’and for with supervision systems via MODBUS;
• the installation requires flexibility in component positioning, thanks to the separately supplied feed pump.

Operational advantages

While maintaining an essential technical setup, this configuration offers concrete advantages in terms of system management and integration.

Automated pressure management

The system RP TRONIC introduces an automatic pressure regulation logic that can be useful to make the daily operation of the unit smoother, reducing the need for manual interventions during operation.

Remote control and better accessibility

The remote control panel allows to organize operations in a more practical way, especially when the unit is installed in technical spaces not always immediately accessible.

Integration into existing systems

The presence of MODBUS as a standard protocol allows considering the insertion of the desalination unit into broader control architectures, where communication between devices is a project requirement. The indicated compatibility with BiBi and Part-NET Interface is an additional useful element during integration.

Installation flexibility

The separate feed pump can facilitate layout design, allowing better management of space, passages, and routine maintenance according to plant requirements.

Use and installation notes

For a correct installation, it is advisable to define the electrical configuration and integration with any control systems in advance. In particular:

• Alimentazioneselect the correct version among the available options (VAC/Hz) based on the plant network.
• Separate componentsconsider that the feed pump is supplied separately and must be planned in the layout.
• MODBUS integrationif connection to supervision systems is planned, plan wiring and interfacing according to the existing architecture.
• Membranesthe SCA series supports configurations with osmotic membranes; the choice/configuration must be defined based on the required setup.

For system compatibility checks, configuration, and accessories, refer to the manufacturer's technical documentation and the supply specifications related to the HP SCA 220-2 code.
