The PWS20-P‑PPSM Series includes 2-inch progressive flow skid-mounted softening systems available in duplex, triplex, and quadplex configurations to meet varying commercial flow demands. With total grain capacities ranging from 150,000 to 600,000 grains, these systems are designed to scale efficiently as demand increases. Progressive flow operation allows multiple tanks to work simultaneously, delivering consistent soft water during peak usage while maintaining system efficiency. Flow rates vary by configuration and model size to support a broad range of application requirements.

Each system utilizes high-capacity cation exchange resin in corrosion-resistant fiberglass mineral tanks and is pre-assembled on a heavy-duty steel skid for streamlined installation. Systems are provided complete with mineral tanks, resin, and control valves, all NSF and ANSI certified. The rugged brass control valves are engineered for durability, configurability, and ease of maintenance, and are operated by advanced electronic controllers that store key operational history. Metered, demand-initiated regeneration ensures the system regenerates only when necessary, reducing water, salt, and operational costs while maximizing efficiency.
