Hydrotek HB8RSLE-UD Automatic Solar-Powered Flush Valve Retrofit Kit (1.0 GPF Urinal)

The Hydrotek HB8RSLE-UD is an industrial-grade, sensor-activated retrofit kit designed to modernize manual Delany urinal flush valves with sustainable solar technology. By integrating high-efficiency energy harvesting with precision electronics, this kit provides a consistent 1.0 GPF (3.8 LPF) flush while virtually eliminating the need for periodic battery maintenance. This "top-down" retrofit solution allows facility managers to upgrade to touchless operation, improving restroom hygiene and ensuring ADA compliance without the labor-intensive requirement of a full valve replacement.

Sustainable Solar Energy Harvesting

• Ambient Light Power System: The HB8RSLE-UD features integrated solar cells engineered to harvest energy from both natural and artificial indoor light. This energy is stored in a long-life internal capacitor, providing a reliable power source that operates independently of the building’s electrical grid.
• Redundant Battery Backup: To ensure 100% operational uptime in low-light environments or during periods of extended darkness, the system includes a redundant battery backup. This dual-power architecture ensures consistent performance regardless of lighting conditions.
• Reduced Maintenance Costs: By utilizing solar energy as its primary power source, the HB8RSLE-UD significantly extends the life of the backup batteries, reducing maintenance labor and the environmental impact of disposable battery waste.

Professional-Grade Engineering & Delany Integration

• Specialized Delany Compatibility: The "UD" designation confirms that this retrofit kit is precision-contoured for a perfect mechanical fit with Delany manual urinal flush valves. This allows for a rapid upgrade that preserves the existing heavy-duty brass valve body while adding modern electronic intelligence.
• Touchless ADA Compliance: Replacing manual handles with a high-performance infrared sensor provides a 100% hands-free user experience. This fulfills ADA accessibility requirements and eliminates a primary surface for cross-contamination, essential for modern public health standards.
• Industrial Piston Reliability: Hydrotek’s proprietary piston technology ensures a precise 1.0 GPF flush volume regardless of water pressure fluctuations. The piston mechanism is highly resistant to mineral buildup and debris, outperforming traditional diaphragm kits in both longevity and maintenance intervals.
• VSI Silicone Elastomer Seals: The internal components feature industrial-grade silicone seals that are highly resistant to chloramines and other aggressive water treatment chemicals, preventing common leak points and ensuring long-term performance.

Intelligent Sensor & Hygiene Features

• True Mechanical Manual Override: For maximum reliability, the HB8RSLE-UD includes a standard manual-mechanical override button. This ensures the urinal remains fully operational for users even if the energy storage is depleted, preventing fixture downtime.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature. If the fixture is not used for a 24-hour period, the system automatically triggers a flush to maintain the trap seal and prevent sewer gases from entering the facility.
• Smart Self-Diagnostics: The electronics include integrated self-diagnostic capabilities and a manual reset function to streamline troubleshooting and ensure consistent performance for facility maintenance teams.
