What it is
The Performance Double adds a second membrane while retaining the modular layout, remote stainless control panel and standard service items. It is positioned for families, liveaboards and larger crews.
Published performance
The current product page states 140 L/h nominal output at 35,000 ppm seawater, 25°C and 800 psi with the 12 L/min pump, or 120 L/h with the 8 L/min option. It uses two DuPont FilmTec SW30-2540 membranes. The broader category label describes the family as up to 160 L/h, so compare models using the exact configured product page rather than the category headline.
Pump and feed options
The published high-pressure choices are 240 V AC, 50 Hz triplex pumps with either a 1.5 kW motor rating (12 L/min) or a 1.1 kW motor rating (8 L/min). Feed-pump choices include a 12 V DC 110 W pump or a 240 V AC Davey XF171S.
Motor ratings are nameplate figures, not measured whole-system running draw. Confirm startup demand and measured running watts for the exact configuration.
Included equipment
The package lists two membrane housings, the high-pressure pump, anti-vibration mounts, 20 and 5 micron pre-filters, freshwater-flush equipment, hoses, fittings, remote instruments and installation documentation.
Best fit
A practical middle ground for cruising families and liveaboards that want shorter run times than a single-membrane system without moving to the largest package.
Compatibility
Best suited to cruising families and liveaboards with a suitable 240 V AC supply and space for two membrane housings.
