300K Meter Twin Alt System w/3050 BT

Topping the commercial twin lineup, the 300K Meter Twin Alt System with 3050 BT delivers maximum capacity and uninterrupted soft water for the most demanding facilities. This Nelsen Connected Series system uses a twin-tank alternating design so one tank always remains in service while the other regenerates, ensuring a constant flow of treated water around the clock without interruption.

Maximum Commercial Capacity

With 300,000 grains of softening capacity, this system is built for large-scale operations where high water volumes and aggressive scale control are critical. It arrives complete with a 1-1/2" commercial twin-tank control valve, upper baskets, 1-1/2" straight male plumbing adapters, commercial distributors, gravel bed, dual mineral tanks, a commercial brine tank with Nelsen 484 brine valve and air check, and high-capacity resin, everything needed for a robust, ready-to-commission commercial installation.

• 300K grain commercial twin-tank alternating softener system
• 1-1/2" commercial twin-tank control valve with Legacy View Bluetooth control
• Dual mineral tanks with commercial distributors and gravel bed
• Commercial brine tank with Nelsen 484 brine valve and air check
• High-capacity resin, upper baskets, and plumbing adapters included

The free Legacy View app for iPhone and Android provides comprehensive control: adjust valve settings, monitor current and historical usage, start a regeneration remotely, store servicing dealer information, and connect to all Legacy View valves in the system. A 9-volt battery backup keeps the electronic meter active and moves the valve to shutoff should power fail during regeneration. By softening at the point of entry, the system protects boilers, water heaters, and process equipment from scale across high-volume use. For large commercial and industrial-adjacent applications that cannot tolerate hard water or downtime, this Nelsen 300K twin system offers the capacity, reliability, and smart monitoring to keep operations running smoothly.

Professional installation by a qualified water treatment dealer is recommended to ensure the twin tanks, brine system, and plumbing are configured for your facility's flow and water chemistry. Once dialed in, the system delivers continuous, worry-free soft water that protects equipment and reduces scale-related maintenance across the entire operation. For facilities that cannot afford hard water or downtime, this Nelsen Connected Series solution combines proven capacity with modern, app-driven convenience.
