Hydrotek HB8CRFKC-025GPF Automatic Urinal Retrofit Kit (0.25 GPF)

The Hydrotek HB8CRFKC-025GPF is an ultra-high-efficiency (UHE), battery-powered concealed retrofit kit designed to modernize manual flushometers with advanced touchless technology. Specifically engineered for behind-the-wall installations, this kit is compatible with industry-standard Sloan Royal/Sloan and Zurn Z9000 series urinal valve bodies. By delivering a precision-calibrated 0.25 GPF (0.9 LPF), this system provides a staggering 75% reduction in water consumption compared to standard 1.0 GPF valves, making it a premier choice for facilities striving for peak LEED performance and maximum utility savings.

Professional-Grade Engineering & Retrofit Compatibility

• Vandal-Resistant Concealed Design: Built for high-security or high-aesthetic environments, this kit houses all electronic and mechanical components behind the wall. This protects the hardware from tampering while maintaining a clean, modern restroom appearance.
• Universal Valve Integration: Precision-engineered to fit existing Sloan and Zurn concealed urinal valve bodies. This enables a swift, cost-effective upgrade to sensor technology without the structural expense of wall demolition or full valve replacement.
• Industrial Piston Accuracy: Unlike traditional diaphragm kits that are prone to failure from sediment or pressure fluctuations, Hydrotek’s superior piston technology ensures consistent flush volumes and an extended service life in demanding commercial settings.
• Chemical-Resistant Seals: Features industrial-grade VSI silicone elastomer seals, specifically formulated to resist degradation from chlorine, chloramines, and ammonia commonly found in treated municipal water.

Advanced Sensor Intelligence

• Touchless ADA Compliance: The advanced infrared sensor provides a completely sanitary, "no-hands" experience, satisfying ADA accessibility standards while drastically reducing the transmission of germs in high-traffic facilities.
• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, providing a reliable solution for retrofitting facilities where electrical hardwiring is unavailable or prohibitively expensive.
• Smart Self-Diagnostics: Equipped with an integrated electronic system that includes self-diagnostics and a manual reset function, simplifying maintenance and ensuring long-term operational consistency.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of low use to maintain the trap seal and prevent sewer gas odors.
• True Mechanical Override: Features 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: Ultra-high efficiency 0.25 GPF (0.9 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, reducing labor costs and restroom downtime during facility-wide upgrades.
