The MARLO ‘MR’ Series is designed for larger commercial and industrial water softening applications. Individual tank capacity ranges from 150,000 grain to 1,050,000 grain with continuous flow rates of 20-190 GPM. Single tank, multi-tank parallel, twin alternating, and triple alternating systems are available with a wide variety of timer and water meter controllers.

Features

• Epoxy lined and prime exterior finished carbon steel pressure vessels. Non-ASME construction with 100 psig working pressure.
• High capacity, sulfonated polystyrene cation exchange resin in sodium-form.
• Galvanized steel face-piping assembly with cast iron, normally-open, “Y” pattern diaphragm control valves.
• Pilot stager valve controller for automatic regeneration operation. Pre-wired in a NEMA-4X enclosure with an adjustable timeclock for regeneration initiation.
• Self-adjusting flow control to maintain accurate backwash rates.
• PVC pressure-compensated brine injector for correct brine flow and concentration.
• PVC media-retaining underdrain distribution system in either hub-radial or header-lateral configurations for minimal pressure drop and proper regeneration.
• Rigid, polyethylene brine tanks with dry-salt shelf platform and water re-fill valves.
