Schenker watermakers are available in 3 models, Zen, Smart and Modular. All units are fitted with an Energy Recovery System, reducing electric consumption to a minimum. Materials, quality and reliability of the 3 models are the same. In the Zen basically all components are integrated in the main manifolds, and there are very few external components such as fittings, hoses & valves. This makes the Zen very compact, with a special ultra-flat design. The Smart and Modular models are based on a more traditional configuration, therefore the main components of the watermaker (ERS, membranes, valves, pipes) are separated, making the inspection and service of the parts very simple. The Smart is mainly based on single, long membranes whereas the Modular makes use of split membranes. Therefore the external dimensions of the 2 machines are quite different, allowing the customer to choose the best option to adapt to the space available. Finally the Zen is available with a Basic remote control panel (this allows remote start/stop, flushing and timing options) whereas the Smart and Modular are available with 3 different control options, Basic, Analogic and Digital.
