Hydrotek HB8CRFKC-05GPF Automatic Urinal Retrofit Kit (0.5 GPF)

The Hydrotek HB8CRFKC-05GPF is a professional-grade, battery-powered concealed retrofit kit designed to upgrade manual flushometers to high-efficiency, touchless operation. Specifically engineered for behind-the-wall installations, this kit is compatible with industry-standard Sloan Royal/Sloan and Zurn Z9000 series urinal valve bodies. Delivering a precision-calibrated 0.5 GPF (1.9 LPF), this system provides a 50% water savings compared to traditional 1.0 GPF valves, making it an essential component for facilities aiming for LEED certification and improved operational efficiency.

Professional-Grade Engineering & Retrofit Compatibility

• Vandal-Resistant Concealed Design: By housing the electronic and mechanical components behind the wall, this kit provides a streamlined, architecturally clean restroom aesthetic while protecting the unit from tampering and accidental damage.
• Seamless Valve Integration: Precision-engineered to fit existing Sloan and Zurn concealed urinal valve bodies. This allows for a rapid, cost-effective upgrade to sensor technology without the need for wall demolition or full valve replacement.
• Industrial Piston Accuracy: Unlike diaphragm kits that can fail due to sediment or pressure drops, Hydrotek’s superior piston technology ensures consistent flush volumes and a longer service life in high-traffic commercial environments.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer seals that are specifically formulated to resist the corrosive effects of chlorine, chloramines, and ammonia found in modern water treatments.

Advanced Sensor Intelligence

• Touchless ADA Compliance: The advanced infrared sensor offers a completely sanitary, "no-hands" experience. This fulfilling ADA accessibility requirements while significantly reducing the spread of germs and improving the user experience.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, this kit is the ideal solution for retrofitting facilities where hardwiring is not feasible or would be cost-prohibitive.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify troubleshooting and streamline facility-wide maintenance.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of inactivity to maintain the fixture’s trap seal and prevent sewer gas odors.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the urinal remains fully functional and flushable even if the batteries are completely exhausted.

Technical Specifications & Installation

• Application: Concealed (behind-the-wall) urinal retrofit.
• Flush Volume: High-efficiency 0.5 GPF (1.9 LPF).
• Operating Range: Engineered for reliable performance across a wide pressure range of 10–125 PSI.
• Simplified Maintenance: Designed for easy integration into existing valve bodies, minimizing labor costs and restroom downtime during facility upgrades.
