Key Features
- ✓ Progressive Flow Design (NHWB): No hard water bypass configuration requires multiple units for parallel operation, delivering continuous soft water during regeneration cycles
- ✓ NXT2 Digital Control System: Advanced 5-cycle fully adjustable control delivers upflow backwash, downflow brining, slow rinse, rapid rinse, and timed brine refill for optimal regeneration
- ✓ Electronic Meter-Initiated Regeneration: Regenerates based on actual water usage rather than time, significantly reducing salt and water consumption while ensuring consistent softening performance
- ✓ Industrial-Grade Fiberglass Pressure Vessel: Polyethylene shell continuously wound with fiberglass and sealed with epoxy resin creates a corrosion-resistant, leak-free tank rated for 30" x 72" capacity
- ✓ Multi-Unit Communication System: On-board CAT 5 communication cables link multiple valves in duplex, triplex, or quadplex configurations for coordinated regeneration and maximum uptime
- ✓ Large Capacity Brine System: 1,200-pound salt storage capacity maximizes time between refills, with 30" x 48" polyethylene brine tank designed for demanding commercial operations
FAQ
Q: What is the difference between HWBP and NHWB models, and why does the NHWB version require multiple units?
A: HWBP (Hard Water Bypass Present) models can operate as single units with bypass capability during regeneration. NHWB (No Hard Water Bypass) models are designed for parallel operation requiring duplex, triplex, or quadplex configurations to ensure continuous soft water supply while one or more units regenerate, making them ideal for facilities requiring uninterrupted soft water 24/7.
Q: How does the meter-initiated regeneration save on operating costs compared to time-based systems?
A: The electronic meter tracks actual water usage and initiates regeneration only when the resin bed reaches capacity, rather than regenerating on a fixed schedule. This prevents unnecessary regeneration cycles during low-usage periods, reducing salt consumption by up to 40% and water waste significantly, while maintaining optimal softening performance.
Q: Can this system handle the high flow demands of commercial laundries, cooling towers, or boiler feed applications?
A: Yes, the CES-3900E-450-NHWB is specifically engineered for high-demand commercial and light industrial applications. A single unit delivers 100 gpm continuous flow, while quadplex installations achieve 400 gpm constant flow. The 3-inch porting and 450,000-grain capacity per tank make it ideal for laundries, cooling towers, boiler protection, hotels, retail superstores, and whole-facility softening applications.
