Hydrotek HB8RSLE-CD Automatic Solar-Powered Flush Valve Retrofit Kit (1.6 GPF Closet)

The Hydrotek HB8RSLE-CD represents the pinnacle of sustainable restroom technology, combining high-performance sensor automation with advanced solar energy harvesting. Specifically engineered for the modernization of manual Delany closet flush valves, this solar-powered retrofit kit provides a consistent 1.6 GPF (6.0 LPF) flush while virtually eliminating the need for routine battery replacements. By utilizing ambient light as its primary power source, the HB8RSLE-CD offers facility managers an eco-friendly, low-maintenance solution for achieving ADA compliance and superior restroom hygiene in high-traffic commercial environments.

Advanced Solar Energy Harvesting & Sustainability

• Ambient Light Power System: The integrated solar panels are designed to harvest energy from both natural and artificial indoor light. This energy is stored in a long-life internal capacitor, providing the sensor and solenoid with a reliable power source that operates independently of the building’s electrical grid.
• Redundant Battery Backup: To ensure 100% uptime in low-light environments or during periods of extended darkness, the system includes a redundant battery backup. This dual-power approach ensures the fixture remains fully operational regardless of lighting conditions.
• Minimal Maintenance Lifecycle: By drastically reducing the frequency of battery changes, the HB8RSLE-CD minimizes maintenance labor costs and reduces the environmental impact associated with disposable battery waste.

Professional-Grade Engineering & Delany Integration

• Precision Delany Compatibility: The "CD" designation confirms that this retrofit kit is custom-tailored for a seamless mechanical fit with Delany brand manual closet flush valves. The installation process preserves the existing heavy-duty brass valve body while upgrading the internal components to state-of-the-art electronic control.
• Touchless ADA Compliance: The advanced infrared sensor provides a 100% hands-free user experience, fulfilling all ADA accessibility requirements. This touchless operation significantly improves facility sanitation by eliminating one of the most common surfaces for cross-contamination.
• Industrial Piston Reliability: Hydrotek’s proprietary piston technology offers a distinct advantage over traditional diaphragm systems. The piston mechanism is exceptionally resistant to mineral deposits, scale, and waterborne debris, ensuring a precise 1.6 GPF flush volume and a longer service life in challenging water conditions.
• 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-CD includes a standard manual-mechanical override button. This ensures the toilet remains fully functional for users even in the absence of light or power, preventing fixture downtime.
• Automated Hygiene (Sentinel) Flush: To maintain fixture freshness and prevent sewer gases from entering the facility, the integrated electronics feature a built-in 24-hour sentinel flush. If the fixture is not used for a full day, the system automatically triggers a flush to maintain the trap seal.
• Smart Self-Diagnostics: The system includes sophisticated self-diagnostic logic and a manual reset function, allowing facility maintenance staff to quickly troubleshoot performance and ensure consistent uptime.
