HP SCA Desalinator: 120 LT/H - code: HP SCA 120-1 - HP Watermakers

HP SCA 120-1 Desalinator (SCA series) – HP Watermakers

The HP SCA 120-1 desalinator belongs to the SCA series by HP Watermakers and is designed for water treatment applications where operational continuity, orderly plant management, and integration with control systems are required. It is a typical solution for technical contexts (such as onboard plant engineering and professional installations) where fresh water production from reverse osmosis must be managed with clear maintenance and supervision criteria.

This version is identified by the HP SCA 120-1 supplier product code and is offered with a configuration consistent with the SCA range, which can be equipped with osmotic membranes and control provisions typical of the family. The feed pump is supplied separate, a useful aspect during installation and plant layout.

System features and details

The SCA series is designed to accommodate osmotic membranes and to support plant configurations oriented towards modularity. Depending on the series configurations, it can reach a production of 440 Lt/h with four 31540 membranes (information referring to the series). The model in question is the variant SCA 120-1, with a rated flow of 120 Lt/h.

Control and integration

For those requiring advanced management, the series includes the version RP TRONIC, which includes:

• automatic pressure regulation system;
• remote control panel.

Furthermore, the standard MODBUS protocol is installed on all units and is indicated as compatible with BiBi e Part-NET Interface. This makes it easier to integrate the desalinator into supervision architectures or into plants where standardized communication between equipment is required.

Available power supplies (supply)

The system can be supplied with the following power supplies:

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

When ordering, it is important to align the required power supply with the available electrical system and the planned installation logics (panel, protections, wiring, and interfacing).

Technical data available

Below are the data reported for this model:

• Flow rate: 120 Lt/h
• Nominal flow rate: 135 Lt/h
• Daily flow rate: 2880 Lt/day
• Nominal daily flow: 3240 Lt/day
• Installed power: 2.2 kW
• Total weight: 65
• Dimensions: 842X420X456

Typical applications

The HP SCA 120-1 desalinator is suitable for applications where the production of fresh water through reverse osmosis is an integral part of plant management. In nautical and technical-professional fields, it can be considered for:

• onboard systems (integration in the engine room or technical room, with predisposition for control and supervision);
• water treatment installations where standard communication (MODBUS) towards monitoring systems is useful;
• contexts in which the separate feed pump facilitates component arrangement and maintenance.

The presence of the MODBUS protocol and declared compatibility with dedicated interfaces make the product interesting when centralizing the management of multiple users or recording operating parameters through external systems is desired.

Operational advantages

Some practical advantages derive from the declared features of the series and model:

• Simplified integration: standard MODBUS on all units, useful for connection to control and supervision systems.
• Power supply flexibility: availability of multiple VAC/Hz variants to adapt to different electrical systems.
• Organized plant management: separate feed pump supplied, useful for customized layouts and accessibility.
• Range scalability: the SCA series includes configurations with osmotic membranes and the possibility to reach higher flow rates (data refers to the series), facilitating product choice alignment with plant needs.

Use and installation notes

For a correct and consistent installation with the plant, it is advisable to consider:

• Check power supply: selecting the correct version among the available power supplies (VAC/Hz) based on the existing network.
• Control integration: if a supervision system is planned, arrange the connection via MODBUS and check the possible need for interfaces (BiBi / Part-NET Interface) based on the existing architecture.
• Component layout: the separate feed pump requires planning of spaces and hydraulic/electrical connections.
• SCA series configuration: for requirements other than the model flow rate, evaluate the overall configuration of the series (membranes and setups) according to the project.

For the final choice and alignment with the system (wiring, accessories, preparations, and configuration), it is advisable to refer to the manufacturer's documentation and the supply data associated with the code HP SCA 120-1.
