SLCE SD11 Compact Design for medium tonnage vessels

The SLCE SD11 Reverse Osmosis (RO) Watermaker series delivers reliable freshwater production from 5 to 12 m³ per day. Therefore, this range suits medium tonnage vessels with limited installation space. Its compact footprint fits fishing vessels, frigates, offshore service vessels, and yachts. As a result, operators secure operational autonomy without compromising onboard layout.

 

Modular Design with Standard Equipment

The SLCE SD11 series features a modular construction that simplifies installation on new builds and retrofits. Consequently, integration remains efficient and cost-effective, even in confined engine rooms. Each system includes a self-priming feed pump with strainer and a low-speed sand filter for optimal pre-filtration. In addition, dual-stage 20µ and 5µ cartridge filtration protects critical components. The high-pressure stainless steel pump and high-rejection membranes ensure stable output and consistent water quality. Automatic flushing low-pressure at high-flow reduces fouling and extends membrane life.

 

Consistent Performance and Controlled Water Quality

To support long-term reliability, the SLCE SD11 series includes Cleaning-in-Place functionality for straightforward maintenance. Continuous salinity monitoring ensures safe freshwater production and automatic diversion when needed. A dedicated re-hardening filter improves water quality for onboard use. As a result, crews benefit from dependable freshwater with minimal supervision. Overall, the SLCE SD11 RO Watermaker combines performance, durability, and ease of operation, making it an ideal solution for demanding marine and remote environments.
