MDAS Series Industrial Chloride Cycle Dealkalizer Systems

Designed for larger industrial boiler-feed applications. Individual tank capacity ranges from 50,000 grain to 980,000 grain with continuous flow rates of 10-300 GPM. Tank diameters from 20″ to 72″ and service pipe connections from 1.25″ NPT to 3″ NPT are available. Single tank, multi-tank parallel, twin alternating, and triple alternating systems are available with a wide variety of timer and water meter controllers. Contact Marlo, Inc. for information on larger tank sizes and custom sized applications.

Features/Benefits

• Epoxy lined and prime exterior finished carbon steel pressure vessels. Non-ASME construction with 100 psig working pressure.
• High capacity, strong-base anion exchange resin in chloride-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-12 enclosure with an adjustable timeclock for regeneration initiation.
• Self-adjusting flow control to maintain accurate backwash rates.
• 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 or wet-salt storage and water re-fill valves.
• Caustic feed system including metering pump, pump stand, and automatic controls.

Optional Equipment

• ASME constructed, stamped, and certified pressure vessels for varying working pressures.
• “Safety Blue” finish painted vessel exteriors. Alternative colors are available.
• Mechanical automatic-reset water meters for volume initiated regeneration.
• Electronic water meters for volume initiated regeneration, flow display, and totalization.
• Twin alternating configurations with remote water meter (mechanical or electronic) and electro-mechanical controller for continuous soft water supply.
• ‘MX’ Electronic programmable cycle controllers for systems up to 3 softener tanks.
• Flexible system control for almost any configuration using timer or volume initiated regeneration. “Additive Flow Feature” for automatically bringing additional tanks on-line as service flow increases.
• Inlet/outlet pressure gauges and sample valves.
• Sch 80 PVC face-piping and thermo-plastic diaphragm valves.
• 304/316 Stainless steel pressure vessels, face-piping, and internal distributors.
• Manual system valves for operator-performed regeneration cycle.
• Bulk brine storage vessels and brine pump skid systems.
• Programmable Logic Control (PLC) electrical packages.
• Skid mounted, pre-piped, and pre-wired systems (for single/multiple softeners).
