Overview
The Deepflow CYQUVLP01 Dual-Wavelength UV Lamp is an engineered ultraviolet irradiation module designed for integration into high-purity and ultrapure water (UPW) generation systems. It emits germicidal and photo-oxidative radiation at two discrete, narrow-band spectral peaks—185 nm and 254 nm—enabling simultaneous microbial inactivation and organic contaminant degradation. At 254 nm, the lamp delivers high-efficiency DNA/RNA photodimerization, achieving >99.9% log reduction of bacteria, viruses, and spores under validated flow and dose conditions. At 185 nm, it generates hydroxyl radicals (•OH) via photolysis of dissolved molecular oxygen and water, facilitating advanced oxidation of trace organics—including TOC precursors such as humic substances, low-molecular-weight aldehydes, and residual pharmaceutical compounds—to CO₂ and H₂O. This dual-action mechanism supports compliance with ASTM D1193 Type I water specifications and ISO 3696 Grade 1 purity requirements when deployed within a fully qualified UPW train.
Key Features
- Stainless steel 316L lamp housing with quartz sleeve optimized for high UV transmittance (>90% at both 185 nm and 254 nm)
- Low-pressure mercury vapor discharge lamp with stabilized arc operation and thermal management for consistent output over 9,000 hours nominal lifetime
- Integrated quartz sleeve cleaning interface compatible with automated mechanical wipers or ultrasonic assist modules
- Modular DIN-rail mounting design enabling seamless integration into existing UPW skids or new system builds
- Real-time UV intensity monitoring via calibrated silicon carbide (SiC) photodiode sensor with analog 4–20 mA output and digital RS485 Modbus RTU interface
- Compliance-ready firmware supporting configurable UV dose calculation (mJ/cm²) based on flow rate, residence time, and real-time sensor feedback
Sample Compatibility & Compliance
The CYQUVLP01 is intended for use exclusively in closed-loop, pressurized ultrapure water distribution systems operating at ≤10 bar and ≤35 °C. It is compatible with deionized feedwater meeting ASTM D1193 Type II or better, and requires pre-filtration through ≤0.22 µm absolute-rated membrane filters to prevent particulate fouling of the quartz sleeve. The unit conforms to IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), and its electrical safety design meets IEC 61010-1 for laboratory and industrial equipment. When installed and validated per manufacturer protocols—including periodic verification using NIST-traceable UV radiometers—it supports adherence to USP Water for Pharmaceutical Purposes, EP 2.2.43 Purified Water, and ISO 14644-1 Class 5 cleanroom water supply requirements.
Software & Data Management
The lamp integrates with standard UPW system SCADA platforms via Modbus RTU or optional OPC UA gateway. UV intensity, cumulative lamp operating hours, and calculated delivered dose are logged at user-defined intervals (1 s to 1 h resolution) and stored locally for ≥30 days. Audit trail functionality records all parameter changes, calibration events, and alarm acknowledgments with user ID and timestamp—fully compliant with FDA 21 CFR Part 11 requirements when paired with a validated electronic record system. Optional cloud-based remote diagnostics provide predictive maintenance alerts based on intensity decay trends and thermal profile anomalies.
Applications
- Final polishing stage in semiconductor-grade UPW systems (ASTM F631, SEMI F57)
- TOC reduction in biopharmaceutical process water loops (≤1 ppb target)
- Endotoxin control in cell culture media preparation water circuits
- UV-assisted ozone destruction in hybrid AOP (Advanced Oxidation Process) configurations
- Validation support for water system requalification per Annex 1 (EU GMP) and FDA Aseptic Processing Guidance
FAQ
What is the recommended maximum flow rate for optimal UV dose delivery?
Optimal performance is achieved at flow rates between 0.5–2.0 L/min per lamp module, depending on pipe diameter and system pressure drop constraints. Dose validation must be performed per IQ/OQ protocol using biodosimetry or radiometric measurement.
Can the CYQUVLP01 replace legacy single-wavelength 254 nm lamps without hardware modification?
Yes—mechanical and electrical interfaces are dimensionally and electrically compatible with standard 254 nm UV modules; however, full qualification per ISO 14644-3 and system-level TOC testing is required post-replacement.
Is lamp intensity calibration traceable to national standards?
Each production batch undergoes factory calibration using NIST-traceable spectroradiometric reference standards; certificate of conformance includes wavelength accuracy (±1 nm), peak irradiance (mW/cm²), and spectral bandwidth (FWHM ≤5 nm).
Does the unit support GLP/GMP audit readiness?
Yes—the embedded data logger, user-accessible event history, and password-protected configuration menus meet core ALCOA+ principles for data integrity when deployed within a validated infrastructure.
