Key Features
- ✓ No Hard Water Bypass (NHWB) Design: Engineered specifically for parallel multi-unit configurations using CAT 5 communication cables to link multiple valves for progressive flow applications
- ✓ Advanced NXT2 Digital Control: Fully adjustable 5-cycle control with electronic meter delivers controlled upflow backwash, downflow brining and slow rinse, rapid rinse, timed brine refill, and downflow service
- ✓ Meter-Initiated Regeneration: Electronic metering system triggers regeneration based on actual water usage, significantly reducing salt consumption and water waste compared to time-clock systems
- ✓ Commercial-Grade Construction: Fiberglass-wound pressure vessel with polyethylene shell continuously wrapped with fiberglass weaving and sealed with epoxy resin for corrosion resistance and leak-free operation
- ✓ Large Capacity Brine Tank: 1,200 lb salt storage capacity maximizes time between refills, reducing maintenance requirements in high-demand commercial settings
- ✓ 3-Inch Porting: Oversized inlet and outlet connections accommodate high flow rates with minimal pressure drop, ideal for whole-facility applications, laundries, boilers, and cooling towers
- ✓ Scalable Configuration: Designed for duplex, triplex, or quadplex installations to achieve continuous flow rates up to 384 GPM in quadplex setups
FAQ
Q: What is the difference between HWBP and NHWB models, and why would I choose the NHWB version?
A: The NHWB (No Hard Water Bypass) models like the EV998076 are specifically designed for parallel operation with multiple units. They use on-board communication cables (CAT 5) to link multiple valves together, ensuring coordinated regeneration cycles and continuous soft water supply. HWBP (Hard Water Bypass) models are single-tank systems with built-in bypass during regeneration. Choose NHWB when you need uninterrupted soft water flow in high-demand commercial applications.
Q: How many units do I need to purchase for a complete NHWB system installation?
A: The CES-3900E-300-NWBP requires multiple units for operation: minimum 2 units for duplex (192 GPM), 3 units for triplex (288 GPM), or 4 units for quadplex (384 GPM) configurations. Each unit must be purchased separately and linked via communication cables, with the brine tank located no more than 15 linear feet from the furthest softener tank.
Q: What type of maintenance is required for the CES-3900E-300-NWBP system?
A: Primary maintenance involves regularly refilling the brine tank with salt (1,200 lb capacity). The advanced NXT2 electronic control handles automatic regeneration cycles based on water usage. The system should be installed in an accessible location for salt refills, and the drain line must maintain proper air-gap separation. Annual inspection of the control valve, O-rings, and distributor assembly is recommended for optimal long-term performance.
